UK Property Glossary: 50+ Terms Every Homebuyer Should Know

UK property transactions are full of jargon. Estate agents, solicitors, mortgage brokers, and surveyors all use specialist terminology that can leave even confident buyers feeling lost. This glossary cuts through the complexity, giving you accurate, UK-specific definitions in plain English.

Whether you have just received your first mortgage illustration and do not know your KFI from your AIP, or you are deep into conveyancing and puzzled by disbursements and covenants, every term you need is here — arranged alphabetically and cross-referenced where terms relate to each other.

Agreement in Principle AIP

Also called a Decision in Principle (DIP) or Mortgage in Principle (MIP), an Agreement in Principle is a written indication from a mortgage lender confirming how much they would be willing to lend you, based on an initial assessment of your income, outgoings, and credit history. It is not a legally binding mortgage offer, but it is invaluable when making offers on properties, as it demonstrates to estate agents and sellers that you have financing likely in place. Most AIPs are valid for 60 to 90 days and involve only a soft credit check, which does not leave a mark on your credit file. Read our complete guide to Agreements in Principle for more detail.

Appraisal

In the UK property context, an appraisal (sometimes called a valuation appraisal) is an estate agent's informal assessment of a property's likely market value and saleability. Unlike a formal mortgage valuation or surveyor's report, it is carried out by an estate agent rather than a qualified surveyor, carries no professional liability, and is typically provided free of charge when marketing a property for sale. Sellers use appraisals to inform their asking price decisions. Buyers should note that appraisals are not the same as a survey and should commission their own independent valuation.

Arrears

Arrears refers to mortgage payments that are overdue and have not been paid by the date they were due. A borrower falls into arrears when they miss one or more monthly mortgage payments. Lenders are required by the Financial Conduct Authority (FCA) to treat borrowers in arrears fairly and to work with them to find a solution before taking enforcement action. Persistent arrears can lead to repossession of the property and a significant negative impact on the borrower's credit history. If you are struggling to meet mortgage payments, contacting your lender early — before missing a payment — gives you the best chance of finding a manageable arrangement.

Bridging Loan

A short-term, secured loan designed to "bridge" a gap in financing — most commonly used when a buyer needs to purchase a new property before their existing property has sold. Bridging loans typically run for a period of a few weeks to 12 months and carry significantly higher interest rates than standard mortgages, as well as arrangement fees and exit fees. They can be arranged much faster than a traditional mortgage. Bridging loans require careful consideration; the costs can mount rapidly if the original property takes longer to sell than anticipated. They are regulated by the Financial Conduct Authority when used for residential purposes.

Building Survey

Also known as a Full Structural Survey or RICS Level 3 Home Survey, a Building Survey is the most comprehensive property survey available in the UK. It is carried out by a qualified surveyor (RICS-accredited) and provides a thorough examination of all accessible parts of the building — including the roof, walls, floors, drainage, and structural elements — together with a detailed written report identifying defects, their likely causes, and repair recommendations. Building surveys are particularly advisable for older properties, those in poor condition, unusual constructions, or any property where you have concerns. They cost more than a HomeBuyer Report, typically £600–£1,500+ depending on property size and location, but can save buyers significant sums by identifying costly problems before exchange of contracts.

Buy to Let BTL

Buy to Let refers to the purchase of a residential property with the specific intention of renting it out to tenants rather than living in it as a primary home. Buy to Let mortgages are a distinct product from standard residential mortgages; they typically require a larger deposit (usually 25% or more), carry higher interest rates, and affordability is assessed primarily on the property's anticipated rental income rather than the borrower's personal income. Since 2017, the tax treatment of Buy to Let has become significantly less favourable, with mortgage interest relief restricted to the basic rate of income tax. Stamp Duty Land Tax surcharges of 3% also apply on second properties and Buy to Let purchases.

Chain

A property chain (or housing chain) is a sequence of linked property transactions where each buyer is also a seller, and the completion of each transaction depends on the others. For example: Buyer A needs to sell their flat to fund the purchase of House B; the seller of House B needs the proceeds to buy Property C. If any link in the chain breaks — because a buyer pulls out, a mortgage falls through, or a survey reveals a problem — the whole chain can collapse, leaving every party in legal limbo. Chains are one of the most common sources of stress and delay in UK property transactions. The longer the chain, the greater the risk of collapse. First-Time Buyers and chain-free sellers are therefore highly valued by other parties in the chain.

Chain-Free

A property described as chain-free (or "no chain") means there are no linked property transactions that need to complete simultaneously. This typically occurs when a seller is downsizing to rented accommodation, selling a probate property, or when a buyer is a first-time buyer with no property to sell. Chain-free transactions tend to proceed more quickly and with less risk of collapse, making chain-free properties particularly attractive. Buyers purchasing a chain-free property may be able to complete within eight to twelve weeks compared to the typical twelve to twenty weeks for a full chain.

Completion

Completion is the final stage of a UK property purchase. On the agreed completion date, the buyer's solicitor transfers the remaining purchase funds (the balance after the deposit paid at exchange of contracts) to the seller's solicitor. Once the seller's solicitor confirms receipt of the full purchase price, the keys are released — usually via the estate agent — and the buyer takes legal ownership of the property. Completion typically takes place at midday, though it can happen at any point during the working day. The buyer must have buildings insurance in place from completion day. SDLT is due and payable within 14 days of completion.

Conveyancer

A conveyancer is a legal professional who handles the transfer of legal ownership of property from one person to another. In the UK, conveyancing work can be carried out either by a licensed conveyancer (regulated by the Council for Licensed Conveyancers) who specialises exclusively in property law, or by a solicitor (regulated by the Solicitors Regulation Authority) who may practise across multiple legal disciplines. Both can handle straightforward residential purchases. Key tasks performed during conveyancing include conducting local authority searches, reviewing the draft contract, raising and responding to enquiries, managing the transfer of funds, and registering the new ownership with the Land Registry. See our conveyancing process guide for a full step-by-step breakdown.

Covenants

Covenants are legally binding obligations or restrictions that are attached to a property and bind both current and future owners. There are two main types: restrictive covenants prevent the owner from doing something with the property (such as building an extension, running a business from home, or keeping certain animals); positive covenants require the owner to do something (such as maintain a boundary fence or contribute to the upkeep of a shared driveway). Covenants are typically registered at the Land Registry and are disclosed by the seller's solicitor during conveyancing. Breaching a covenant can expose the owner to legal action from the beneficiary of the covenant. Old covenants on older properties can sometimes be obscure or unenforceable, but buyers should always seek legal advice before assuming a covenant can be ignored.

Deposit

In the context of buying a property, "deposit" refers to two related but distinct things. The mortgage deposit is the upfront lump sum you contribute from your own savings towards the property's purchase price; the lender provides the remainder as a mortgage loan. The deposit is typically expressed as a percentage of the purchase price (e.g., a 10% deposit on a £250,000 property = £25,000), and a larger deposit results in a lower Loan to Value (LTV) ratio and better mortgage rates. The exchange deposit is the sum paid to the seller's solicitor at exchange of contracts to make the sale legally binding — this is usually 10% of the purchase price and is separate from (but part of) your total mortgage deposit. If you pull out after exchange without legal justification, you forfeit the exchange deposit.

Disbursements

Disbursements are the third-party costs that your solicitor or conveyancer pays on your behalf during the property purchase process, and then recharges to you. They are separate from the solicitor's own professional fees. Common disbursements include: local authority searches (£250–£400); Land Registry fees for registering the new ownership (£20–£910 depending on property value); electronic money transfer fees (£20–£50); anti-money-laundering checks (£6–£20); and environmental, drainage, and water searches (£30–£100 each). Always ask your solicitor for a full, itemised quote that includes both their fees and all anticipated disbursements so there are no surprises at completion.

Draft Contract

The draft contract is the initial version of the legal contract for the sale and purchase of a property, prepared by the seller's solicitor and sent to the buyer's solicitor at the start of the conveyancing process. It sets out the agreed terms of the sale, including the purchase price, the property boundaries, what fixtures and fittings are included, any known defects, and the legal title information. The buyer's solicitor reviews the draft contract, raises any necessary enquiries with the seller's solicitor, and negotiates amendments before both parties are happy to proceed to exchange of contracts. The process of reviewing and finalising the draft contract is one of the most time-consuming parts of conveyancing.

EPC Energy Performance Certificate

An Energy Performance Certificate (EPC) is a document that rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient), along with an estimated annual energy cost and recommendations for improving the rating. In England, Wales, and Northern Ireland, it is a legal requirement to have a valid EPC (issued within the last 10 years) before marketing a property for sale or rent. EPCs are carried out by accredited domestic energy assessors. A property's EPC rating can affect its value, its appeal to buyers, and — for landlords — whether it can legally be let. Since 2020, rental properties in England must have a minimum EPC rating of E; proposals to raise the minimum to C are under consultation. Buyers should check the EPC of any property they are considering, as a poor rating can mean high energy bills.

Equity

Equity is the portion of your property's value that you own outright, free of any mortgage debt. It is calculated as the current market value of the property minus the outstanding mortgage balance. For example, if your property is worth £300,000 and your remaining mortgage is £180,000, your equity is £120,000 (40%). Equity builds over time as you repay your mortgage and/or as the property's value increases. Equity can be accessed through remortgaging or through equity release products (for older homeowners). It forms the basis of your deposit when you move to a larger property. Negative equity occurs when the property's value falls below the outstanding mortgage balance.

Exchange of Contracts

Exchange of contracts is the legally binding milestone in a UK property transaction. Both the buyer and seller sign identical copies of the final agreed contract, and those copies are formally "exchanged" between their respective solicitors, usually by telephone. From this point, neither party can withdraw without incurring significant financial penalties — the buyer forfeits their deposit (typically 10%) if they pull out, and the seller may be sued for breach of contract if they withdraw. The completion date is agreed at exchange. Exchange can occur on the same day as completion (known as "simultaneous exchange and completion") in some chain-free transactions, but more commonly there is a gap of one to four weeks between the two events, allowing time for removals to be booked and final preparations to be made.

First-Time Buyer

A first-time buyer is someone who has never previously owned a residential property, anywhere in the world, either alone or with another person. This status confers several financial benefits in the UK: relief from Stamp Duty Land Tax on properties up to £300,000 (and a reduced rate on the £300,001–£500,000 portion); eligibility for a Lifetime ISA with a 25% government bonus; and access to specific mortgage products and government homebuying schemes such as Shared Ownership and First Homes. If you are buying jointly with someone who has previously owned property, you will not qualify as a first-time buyer for SDLT purposes even if you yourself have never owned. HMRC can challenge first-time buyer status, so it is important to declare accurately. Read our complete first-time buyer guide for full details.

Fixed Rate Mortgage

A fixed rate mortgage is a mortgage where the interest rate — and therefore the monthly repayment — is locked in at a set level for an agreed initial period, typically two, three, or five years (though ten-year and even lifetime fixed rates exist). After the fixed period ends, the rate usually reverts to the lender's Standard Variable Rate (SVR), which is almost always higher. Fixed rates provide certainty and protection against interest rate rises, making them particularly popular with first-time buyers who are budgeting carefully. The trade-off is that you will not benefit if interest rates fall. Early repayment charges (ERCs) usually apply if you pay off or switch the mortgage before the fixed period ends.

Freehold

Freehold is a form of property ownership in England and Wales where the owner owns the property and the land it stands on outright, with no time limit and no obligation to pay ground rent or service charges to any other party. Most houses in the UK are sold as freehold. Freehold ownership is generally considered preferable to leasehold because there is no lease to expire, no freeholder to deal with, and no ongoing charges for ground rent or building management. When buying a freehold property, the owner takes on full responsibility for maintaining both the building and the land. Some newer houses are sold as leasehold, which has been controversial; legislative reforms are gradually improving protections for leasehold house owners.

Full Structural Survey

See Building Survey. A Full Structural Survey is the older, informal name for what RICS now classifies as a Level 3 Home Survey. It is the most detailed level of survey available, covering every accessible element of the property's structure and fabric. It is most appropriate for properties that are old, in poor condition, of unusual construction (e.g., timber-framed, thatched, or concrete), or where significant works are planned. The report is substantial and detailed, giving the buyer a comprehensive picture of the property's condition, all known defects, and guidance on repair and maintenance priorities.

Gazumping

Gazumping occurs when a seller accepts a higher offer from a new buyer after having already verbally agreed to sell to another buyer, leaving the original buyer without the property they believed they were purchasing. In England and Wales, a property sale is not legally binding until exchange of contracts, meaning sellers are technically free to accept any offer up to that point. Gazumping is most common in a rising market where demand outstrips supply. Buyers can reduce the risk of being gazumped by moving quickly through the legal process, asking the seller to take the property off the market upon acceptance of their offer, and considering a lock-out agreement. Scotland operates under a different legal system and gazumping is far less common there because offers are binding much earlier in the process.

Gazundering

Gazundering is the opposite of gazumping: it occurs when a buyer reduces their offer at the last moment — typically just before exchange of contracts — exploiting the seller's desire not to lose the sale or restart the process. The buyer essentially uses the seller's sunk costs (solicitor fees, time invested, dependence on the chain continuing) as leverage to renegotiate the price downward. While technically legal before exchange, gazundering is widely regarded as unethical and can cause considerable distress. It is most prevalent in falling or uncertain markets. Sellers can protect themselves by ensuring their own position is strong before proceeding and by carefully vetting buyers' financial readiness and commitment at the outset.

Ground Rent

Ground rent is an annual charge that the owner of a leasehold property pays to the freeholder (also called the landlord or ground landlord) in exchange for the right to occupy the land on which the property sits. Historically, ground rents were often small (sometimes peppercorn — £1 per year) and purely symbolic. However, in the 2010s many new-build leasehold properties were sold with ground rents that doubled every ten or twenty-five years, creating significant financial burdens and making properties difficult to sell or mortgage. The Leasehold Reform (Ground Rent) Act 2022 banned the charging of ground rent on new residential leases in England and Wales, though existing leases with ground rent provisions remain in place. Buyers of leasehold properties should always check the ground rent terms carefully before proceeding.

Help to Buy

Help to Buy was the name given to a series of UK government homebuying schemes designed to make property more accessible, particularly for first-time buyers. The most well-known was the Help to Buy: Equity Loan scheme, under which the government lent buyers up to 20% (40% in London) of the purchase price of a new-build property, requiring only a 5% deposit and a 75% (55% in London) mortgage. The scheme closed to new applications in England in October 2022. The Help to Buy: ISA, a savings account with a government bonus, also closed to new entrants in November 2019 (though existing holders could continue saving until November 2029). In 2026, the main government-backed homebuying initiatives include the Lifetime ISA, Shared Ownership, and the First Homes scheme.

HomeBuyer Report

A HomeBuyer Report (officially an RICS Level 2 Home Survey) is the most commonly commissioned property survey in England and Wales. It is carried out by a RICS-qualified surveyor and provides a standard-format report covering the condition of all visible and accessible parts of the property, using a traffic-light rating system (1 = no action needed; 2 = repair or investigate; 3 = urgent investigation or repair). It typically includes an opinion on the market value of the property. A HomeBuyer Report is suitable for conventional, modern properties in reasonable condition. For older, unusual, or significantly deteriorated properties, a Building Survey provides more depth. Costs typically range from £350–£750 depending on property size and location.

HMRC His Majesty's Revenue and Customs

HMRC is the UK's tax authority, responsible for the collection of taxes and the administration of certain benefits. In the context of property transactions, HMRC is relevant because Stamp Duty Land Tax (SDLT) must be reported and paid to HMRC within 14 days of completion. HMRC also oversees Capital Gains Tax (CGT) on gains made when selling a property that is not your principal private residence. HMRC's anti-money-laundering requirements mean that solicitors must verify the source of funds used in property transactions. If you are buying through a company, additional HMRC reporting obligations may apply.

Interest-Only Mortgage

On an interest-only mortgage, the borrower's monthly payments cover only the interest on the loan — not any of the capital (the original amount borrowed). This means that at the end of the mortgage term, the full original loan amount is still outstanding and must be repaid in full. To qualify for an interest-only mortgage, lenders require borrowers to demonstrate a credible repayment strategy, such as savings, investments, the sale of assets, or a future inheritance. Interest-only mortgages were common before the 2008 financial crisis but fell sharply after tighter regulation was introduced. They remain available for borrowers with significant equity and a sound repayment plan, and are more common in Buy to Let lending. Monthly payments on an interest-only basis are lower than on a repayment mortgage, but the overall cost of the loan over the full term is significantly higher.

Joint Mortgage

A joint mortgage is a mortgage taken out by two or more people together — typically a couple, friends, siblings, or a parent and child. All named borrowers are jointly and severally liable for the mortgage debt, meaning that if one party cannot pay, the others are still responsible for the full repayment. Lenders typically use all applicants' incomes in the affordability assessment, which can allow the group to borrow more than any individual could alone. Joint mortgages can be held as joint tenants or tenants in common, and the ownership structure has significant implications for what happens if one party dies, wants to sell, or defaults. A formal agreement — sometimes called a cohabitation agreement or declaration of trust — is strongly advisable for non-married joint owners.

Joint Tenancy

Joint tenancy is one of two ways in which co-owners can legally hold property together (the other being tenants in common). Under a joint tenancy, all owners hold equal and undivided shares of the property, and crucially, the right of survivorship applies — if one owner dies, their share automatically passes to the surviving owner(s), regardless of what their will says. Joint tenancy is the default ownership structure for married and civil partner buyers in England and Wales. It is not possible for one joint tenant to leave their share of the property to someone other than the co-owner in their will; the right of survivorship always takes precedence. Joint tenancies can be converted to tenancies in common (a process called "severing the joint tenancy") with notice to the co-owner.

Key Facts Illustration KFI

A Key Facts Illustration (KFI) is a standardised document that mortgage lenders and brokers are legally required to provide to borrowers before recommending or offering a mortgage product. It sets out the key terms of the mortgage in a prescribed format, including: the total amount borrowed; the interest rate and type (fixed/variable/tracker); the monthly repayment amount; the total amount repayable over the full mortgage term; any fees and charges; and information about what happens when the initial deal period ends. The KFI was introduced by the FCA (then FSA) to allow borrowers to compare mortgage products on a like-for-like basis. It has largely been replaced by the European Standardised Information Sheet (ESIS), but the term KFI remains in common use. Always review the KFI carefully before committing to a mortgage product.

Land Registry

HM Land Registry is the government body responsible for registering the ownership and interests of land and property in England and Wales. When you buy a property, your solicitor submits an application to Land Registry to register the change of ownership in your name; this is one of the final steps of the conveyancing process and typically takes several weeks to complete. The Land Registry maintains a publicly searchable register — the title register — which records the legal owner, the property's title (freehold or leasehold), any mortgage charges, and any rights, restrictions, or covenants affecting the property. Official copies of title documents can be obtained online for a small fee. Land Registry fees are a standard disbursement on any purchase, scaled according to the property's value.

Leasehold

Leasehold is a form of property ownership in which the buyer purchases the right to occupy a property for a fixed period of time — the lease — but does not own the land on which the property stands, which belongs to the freeholder. Most flats in England and Wales are sold as leasehold; some houses are also sold leasehold, though this practice has been increasingly criticised. Leasehold owners typically pay annual ground rent and service charges to the freeholder or managing agent, must comply with the terms of the lease (e.g., no pets, no sub-letting without consent), and must obtain the freeholder's permission for major alterations. As a lease shortens — particularly when it falls below 80 years — extending it becomes more expensive and finding a mortgage more difficult. Buyers should always check the lease length and terms before proceeding.

LTV Loan to Value

Loan to Value (LTV) is the ratio of the mortgage loan to the value of the property, expressed as a percentage. For example, if you are buying a £200,000 property with a £180,000 mortgage and a £20,000 deposit, your LTV is 90%. LTV is one of the most important factors lenders use to price mortgage products: the lower the LTV, the lower the risk to the lender, and consequently the better the interest rate offered to the borrower. The most significant rate improvements typically occur at LTV thresholds of 90%, 85%, 80%, and 75%. Lenders generally do not offer residential mortgages above 95% LTV. Your LTV will naturally decrease over time as you repay the mortgage capital and/or as the property value increases, enabling you to access better rates when you remortgage.

Local Authority Search

A local authority search is a standard enquiry made by your solicitor to the local council during the conveyancing process. It reveals information held by the council about the property and surrounding area, including: whether the property is in a conservation area or listed building; any planning permissions or enforcement notices affecting the property; whether the road outside is adopted (i.e., maintained at public expense); any proposals for road schemes, compulsory purchase, or major development in the vicinity; and whether the property is connected to public sewers. Local authority searches typically cost £250–£400 and take between one and six weeks, depending on the council's workload. Many solicitors also recommend drainage and water searches, and environmental searches, as additional disbursements.

Mortgage Broker

A mortgage broker (also called a mortgage adviser) is an intermediary who searches the mortgage market on your behalf to find the most suitable product for your circumstances. Brokers can be: whole of market (with access to products from all or most lenders, including some exclusive deals not available directly); multi-tied (able to recommend products from a selected panel of lenders); or tied (representing only one lender). Most high street mortgage brokers are fee-free, earning commission from the lender upon completion of the mortgage. A good broker will assess your full financial picture, explain your options clearly, and manage the application process on your behalf. Using a broker is particularly valuable if you have a complex financial situation, are self-employed, or have a limited credit history.

Mortgage Deed

The mortgage deed is the legal document that creates a charge (a form of security interest) over the property in favour of the mortgage lender. By signing the mortgage deed, the borrower grants the lender the right to repossess and sell the property if the borrower defaults on the mortgage repayments. The mortgage deed is prepared by the lender and signed by the borrower (and co-borrowers, if any) in the presence of a witness, usually just before completion. It is then registered at the Land Registry alongside the new ownership. The charge created by the mortgage deed is removed from the Land Registry title only when the mortgage is fully repaid.

Mortgage Offer

A mortgage offer is the formal, written document issued by a lender confirming that they will provide a mortgage on specified terms, subject to any conditions. It is distinct from an Agreement in Principle, which is a preliminary indication; a mortgage offer is made only after the lender has conducted a full assessment of the borrower's financial situation, completed a mortgage valuation of the property, and is satisfied to proceed. A mortgage offer is typically valid for three to six months. Once a mortgage offer is in place, the buyer's and seller's solicitors can work towards exchange of contracts. Some lenders may add conditions to the offer (e.g., requiring remedial works before drawdown, or confirmation of certain income) which must be satisfied before the mortgage can proceed to completion.

Mortgage Valuation

A mortgage valuation (also called a lender's valuation) is a brief inspection of the property carried out by a surveyor on behalf of the mortgage lender — not the buyer — to confirm that the property is worth at least the purchase price and represents adequate security for the loan. It is not a survey of the property's condition; it is purely a lender risk assessment and will not identify structural defects, damp, or other problems in detail. Buyers must not rely on a mortgage valuation as a substitute for commissioning their own survey. The cost of the mortgage valuation (£150–£400) is usually charged to the buyer by the lender, though some lenders offer free valuations as part of their mortgage product. Always instruct a separate HomeBuyer Report or Building Survey to protect your own interests.

Negative Equity

Negative equity occurs when the outstanding balance of a mortgage exceeds the current market value of the property. For example, if you bought a property for £200,000 with a 5% deposit (£190,000 mortgage), and the property subsequently falls in value to £175,000, you are in negative equity by £15,000. Negative equity is not an immediate problem if you continue making mortgage payments and do not need to move — the mortgage can simply continue. However, it becomes problematic if you want to sell, remortgage to a better deal, or if you default and the lender repossesses the property and cannot recover the full debt. Negative equity is most common after periods of rapid house price growth followed by a downturn, and disproportionately affects buyers with small deposits.

New Build

A new-build property is one that has been newly constructed and has not previously been lived in. New builds in the UK are typically sold by developers directly or through estate agents. They often come with a NHBC Buildmark warranty (or similar) covering structural defects for ten years from construction — two years of full builder's warranty followed by eight years of structural guarantee. New builds attract several specific mortgage considerations: lenders often impose restrictions on the maximum LTV for new builds (frequently 85% for flats); valuers sometimes "down-value" new builds relative to their asking price; and developer-paid incentives (such as cashback or paid stamp duty) must be disclosed to the lender. The purchaser also typically has no ability to negotiate on price with a large developer, though incentives and upgrades may be negotiable.

Offer

In the UK property market, an offer is the price a buyer puts forward to a seller for the purchase of a property, submitted verbally or in writing through the estate agent. Unlike in Scotland (where formal offers are made through solicitors and are legally binding once accepted), in England and Wales an offer — and even an acceptance — is entirely non-binding until exchange of contracts. This means either party can withdraw at any point before exchange without legal penalty, which is why gazumping and gazundering are possible. When making an offer, buyers should state any conditions (such as including certain fixtures) and confirm their financial position and timeline. It is common practice to offer below the asking price, though in competitive markets, offers at or above asking price may be required.

Overpayment

A mortgage overpayment is when a borrower pays more than their required monthly mortgage payment, reducing the outstanding capital balance faster than the scheduled repayment plan. Overpaying saves money on interest over the life of the mortgage and shortens the mortgage term. Most lenders allow overpayments of up to 10% of the outstanding balance per year without penalty; overpaying beyond this threshold during a fixed rate deal typically triggers early repayment charges. Even modest regular overpayments — for example, an extra £100 per month on a £200,000 mortgage — can save thousands of pounds in interest and shave years off the term. Buyers should check their lender's overpayment terms in their mortgage offer and KFI.

Property Chain

See Chain. The term "property chain" and "housing chain" are interchangeable and refer to the sequence of interdependent transactions that must all complete simultaneously for any individual sale in the sequence to proceed. Managing a property chain effectively requires all parties — buyers, sellers, solicitors, mortgage lenders, and estate agents — to communicate promptly and progress their own side of the transaction in a timely manner. Estate agents often take on an informal coordination role in managing chains, chasing all parties for updates and helping to resolve bottlenecks.

Property Survey

A property survey is an inspection of a property carried out by a qualified surveyor to assess its condition and identify any defects or risks. There are three main levels of survey available in England and Wales, classified by RICS: Level 1 (Condition Report — a basic overview for newer, conventional homes); Level 2 (HomeBuyer Report — the most popular, covering all visible elements with a traffic-light rating and market value opinion); and Level 3 (Building Survey / Full Structural Survey — the most comprehensive, recommended for older or unusual properties). A survey is distinct from a mortgage valuation, which is for the lender's benefit only. Commissioning your own survey is one of the most important steps a buyer can take to protect their investment and avoid unexpected repair costs.

Remortgage

Remortgaging is the process of switching your existing mortgage to a new deal — either with your current lender (a product transfer) or with a different lender entirely — without moving home. The most common reason to remortgage is to secure a better interest rate when an initial fixed or tracker deal comes to an end, avoiding the lender's more expensive Standard Variable Rate (SVR). Remortgaging can also be used to release equity from the property (borrowing more against its increased value), to consolidate debts, or to change the mortgage term. The remortgaging process is generally simpler and faster than a purchase, though it still involves a valuation and, if switching lender, a conveyancer. Remortgaging costs can include exit fees from the old lender, arrangement fees from the new lender, and legal fees, so it is important to calculate whether the savings outweigh the costs.

Repayment Mortgage

A repayment mortgage (also called a capital and interest mortgage) is the most common type of mortgage in the UK. Each monthly payment covers both the interest accruing on the loan and a portion of the original capital borrowed. In the early years of the mortgage, payments are weighted more heavily towards interest, with only a small amount reducing the capital. Over time, as the capital reduces, the proportion of each payment going towards capital increases. If all payments are made as scheduled, the mortgage will be fully repaid at the end of the agreed term, leaving the borrower owning the property outright. This contrasts with an interest-only mortgage, where the capital remains outstanding throughout. The vast majority of residential mortgages in the UK are on a repayment basis.

RICS Royal Institution of Chartered Surveyors

RICS is the professional body that sets and enforces standards for property surveying and valuation in the UK and internationally. RICS-qualified surveyors (who hold the designation MRICS or FRICS) carry out HomeBuyer Reports, Building Surveys, mortgage valuations, and other property assessments. When commissioning a survey, buyers should always ensure the surveyor is RICS-accredited, as this provides a level of professional assurance and recourse if the survey proves negligent. RICS also publishes guidance and data on the UK property market, including the widely cited RICS Residential Market Survey, which tracks supply and demand trends.

SDLT Stamp Duty Land Tax

Stamp Duty Land Tax is a tax levied by HMRC on purchases of land or property in England and Northern Ireland above set thresholds. (Scotland uses Land and Buildings Transaction Tax; Wales uses Land Transaction Tax.) SDLT is calculated on a tiered basis, with different rates applying to different portions of the purchase price. In 2026, first-time buyers pay no SDLT on the first £300,000, then 5% on the portion from £300,001 to £500,000. For non-first-time buyers, the standard residential rates apply. Properties purchased as second homes or Buy to Let investments attract a 3% surcharge on each band. SDLT must be paid to HMRC within 14 days of completion, and the solicitor typically handles this on the buyer's behalf. Use our stamp duty calculator to find out exactly what you will pay.

Shared Ownership

Shared Ownership is a government-backed scheme that allows buyers to purchase a share of a property (typically between 10% and 75% of its value) and pay subsidised rent on the remaining share, which is owned by a housing association. The buyer takes out a mortgage on their purchased share only, making the scheme accessible to those who cannot afford to buy on the open market. Over time, buyers can purchase additional shares (a process called "staircasing") until they own 100% of the property. Shared Ownership properties are always leasehold, and buyers must pay both mortgage costs on their share and monthly rent on the housing association's share, plus service charges. Eligibility criteria vary by scheme and location; generally, household income must be below £80,000 per year (£90,000 in London).

Solicitor

In a property purchase, the solicitor is the qualified lawyer who handles the legal aspects of buying the property on the buyer's behalf — a process called conveyancing. Their duties include reviewing the draft contract, conducting local authority searches and other enquiries, raising questions with the seller's solicitor, managing the transfer and receipt of funds, handling SDLT payments, and registering the new ownership with the Land Registry. Solicitors are regulated by the Solicitors Regulation Authority (SRA). While a licensed conveyancer can handle straightforward purchases, a solicitor may be preferred for complex transactions. Solicitor fees for a residential purchase typically range from £1,000 to £1,800 including VAT, plus disbursements.

Structural Survey

See Building Survey and Full Structural Survey. "Structural survey" is the informal, widely used term for the most detailed level of property inspection available from a RICS-qualified surveyor. Despite the name, a full structural survey covers more than just structural elements — it assesses all accessible parts of the building, including the roof, walls, floors, windows, plumbing, drainage, and electrical systems where visible. The resulting report details all defects found, their probable causes, urgency, and recommended action. It is especially recommended for properties built before 1960, any property requiring significant work, unusual constructions, or where the buyer wants comprehensive knowledge before committing.

Subject to Contract

The phrase "subject to contract" (sometimes abbreviated to STC) is used in UK property transactions to indicate that any agreement reached is not yet legally binding — it remains conditional until exchange of contracts takes place. When a seller accepts a buyer's offer, the agreement is described as "subject to contract" because either party can still withdraw without legal penalty. This is fundamentally different from the Scottish system, where an accepted offer creates a binding contract earlier in the process. You may see "STC" or "SSTC" (Sold Subject to Contract) on property listings online, indicating that an offer has been accepted but the sale has not yet legally completed.

Subsidence

Subsidence is the downward movement of a building's foundations, caused by the ground beneath shrinking, compressing, or collapsing. It can be caused by clay soils drying out and shrinking in dry summers, tree roots absorbing moisture from the soil, leaking drains washing away ground, or former mine workings. Subsidence manifests as cracks in walls — typically diagonal cracks wider at the top than the bottom — as well as sticking doors and windows. It can be a serious and expensive problem to remediate and can affect a property's insurability and mortgageability. A RICS Building Survey will identify evidence of past or active subsidence. Properties with a history of subsidence can be more difficult to insure and may require specialist insurers at higher premiums.

Surveyor

A surveyor is a qualified professional who inspects and reports on the condition and/or value of property. In the context of buying a home, the most relevant surveyor is a chartered surveyor who is a member of the Royal Institution of Chartered Surveyors (RICS) — designated MRICS or FRICS. RICS-qualified surveyors carry out HomeBuyer Reports, Building Surveys, and mortgage valuations. When commissioning a survey, buyers can find RICS-regulated surveyors through the RICS "Find a Surveyor" directory. It is advisable to use a local surveyor with knowledge of the property types in your area. Never rely on the mortgage lender's valuation surveyor — their survey is for the lender's benefit only.

Tenants in Common

Tenants in common is one of two ways co-owners can hold property together in England and Wales (the other being joint tenancy). Under tenants in common, each owner holds a defined and separate share of the property — shares need not be equal; one owner might hold 60% and the other 40%, for example, reflecting different contributions to the deposit. Crucially, there is no right of survivorship: if one owner dies, their share passes according to their will (or intestacy rules if there is no will), not automatically to the co-owner. This makes tenants in common the preferred ownership structure for unmarried couples with unequal contributions, business partners, or anyone who wishes to pass their share to a third party such as a child. A Declaration of Trust is strongly advisable to document each owner's share.

Title Deeds

Title deeds are the legal documents that prove ownership of a property and record the history of its ownership, together with any rights, restrictions, and covenants attached to it. Since the introduction of compulsory Land Registry registration, physical title deeds are no longer required to prove ownership — instead, the Land Registry holds a digital title register that fulfils this function. However, older, unregistered properties may still have physical deeds. When you buy a property, your solicitor will obtain official copies of the title register and title plan from the Land Registry; these confirm the seller's right to sell and reveal any interests that could affect your ownership. The original deeds (if they exist) are often retained by the mortgage lender while the mortgage is in place.

Tracker Mortgage

A tracker mortgage is a variable rate mortgage where the interest rate moves in direct relation to a specified external benchmark — usually the Bank of England base rate — plus a fixed margin. For example, a mortgage at "base rate + 1.5%" would be 6.75% if the base rate were 5.25%. When the Bank of England increases the base rate, tracker mortgage payments rise; when it cuts the base rate, payments fall. Trackers offer transparency (the rate movement is mechanically linked to a public index) and can be cheaper than fixed rates when rates are falling. However, they expose borrowers to the risk of payment increases. Some trackers have an interest rate "collar" — a minimum rate below which they will not fall — but not all. Trackers are usually available with or without early repayment charges.

Transfer Deed

The transfer deed (formally known as the TR1 form for registered land) is the legal document that transfers ownership of a property from seller to buyer. It is prepared by the seller's solicitor and signed by both parties before or at completion. The transfer deed is then submitted to the Land Registry by the buyer's solicitor to update the register, formally recording the buyer as the new legal owner. The TR1 also records the manner in which co-buyers will hold the property — as joint tenants or tenants in common — and any restrictions that apply. The transfer of title at Land Registry is not instantaneous; it typically takes several weeks to several months after completion, depending on Land Registry workload.

Underwriter

An underwriter is a specialist within a mortgage lender who assesses mortgage applications in detail and makes the final lending decision. When a mortgage broker or lender's own adviser submits your application, it is reviewed by the underwriter, who analyses your income, expenditure, credit history, employment status, and the surveyor's valuation of the property to determine whether the application meets the lender's criteria. For straightforward applications, underwriting can be partially automated; for more complex cases — such as self-employed applicants, recently changed jobs, or unusual property types — a human underwriter will review the case in full. The underwriter may request additional documentation (such as further proof of income or clarification of a credit issue) before issuing a mortgage offer.

Universal Credit (impact on mortgages)

Universal Credit is the main means-tested benefit in the UK, replacing six previous benefits including Housing Benefit, Tax Credits, and Income Support. For mortgage applicants, Universal Credit income can be considered by some lenders when assessing affordability, though policies vary significantly between lenders — some will include it in full, some partially, and others not at all. Borrowers who receive Universal Credit while working may find it counts positively alongside their employment income. Separately, homeowners on Universal Credit may be eligible for Support for Mortgage Interest (SMI) — a government loan that pays the interest on mortgage payments for those who qualify. SMI is a loan, not a grant, and is secured against the property and must be repaid with interest when the property is sold.

Valuation

In property, a valuation is a professional assessment of a property's market value at a given point in time, conducted by a qualified RICS surveyor. The most common form in a purchase transaction is the mortgage valuation, commissioned by the lender to confirm the property is worth the purchase price. However, buyers can also commission their own independent valuation for any purpose. A valuation is distinct from an appraisal (an informal estate agent's estimate) and from a full survey (which assesses condition as well as value). If a surveyor values a property below the agreed purchase price — known as a "down valuation" — the lender will typically only lend against the lower value, requiring the buyer to bridge the gap from additional savings, renegotiate the purchase price with the seller, or withdraw from the transaction.

Variable Rate Mortgage

A variable rate mortgage is any mortgage where the interest rate can change over time, in contrast to a fixed rate mortgage where the rate is locked in for an agreed period. The main types of variable rate mortgage in the UK are: the Standard Variable Rate (SVR) — the lender's default rate, which the lender can change at any time and which is typically the most expensive option; the tracker mortgage — which moves directly with the Bank of England base rate; and the discount rate — which is set at a fixed margin below the lender's SVR. Variable rate mortgages can be cheaper than fixed rates when interest rates are low or falling, but they expose borrowers to payment increases when rates rise. Most buyers coming to the end of a fixed rate deal are advised to remortgage rather than fall onto the SVR.

Zero Hours Mortgage

A "zero hours mortgage" is an informal term used in the UK mortgage industry to describe a mortgage applied for by a borrower who is employed on a zero-hours contract — a working arrangement with no guaranteed minimum hours, where hours worked (and therefore earnings) can fluctuate significantly week to week. Zero-hours contract workers can obtain a mortgage, but they face greater scrutiny from lenders. Lenders typically require at least 12 months' employment history on the contract (some require two years), consistent evidence of income, and will usually base affordability calculations on an average of recent earnings rather than a fixed salary. Using a specialist mortgage broker familiar with non-standard income types is strongly recommended. Some lenders specifically accommodate zero-hours contract applicants; others will not consider them at all.
