UK Property Buying Guide 2026/27 | The Complete Home-Buying Process

Buying a home in England or Wales is a process with a fixed skeleton: agree a price, secure a mortgage, instruct a solicitor to run the legal work, commission a survey, exchange contracts, then complete. A straightforward purchase can take several months and chains can take longer; the biggest cost surprises come from Stamp Duty Land Tax (SDLT), surveys and legal fees that sit on top of the deposit. Northern Ireland and Scotland have different process and tax rules. Understanding each step before you commit keeps the process moving and stops a low offer becoming an expensive purchase.

The two numbers that matter most at the start are what you can borrow and what the tax bill will be. Model both with the Mortgage Calculator→ and the Stamp Duty Calculator→ before you view properties, so every offer you make is grounded in real affordability.

Step 1: Mortgage Affordability Before You Offer

Lenders typically cap borrowing at around 4.5 times gross annual income, though some stretch to 5–5.5 times for strong applications, and affordability tests apply to your committed outgoings as well as income. Your deposit sets the loan-to-value (LTV): a 10% deposit means a 90% LTV mortgage, which carries higher rates; pushing to a 15% or 20% deposit drops you into cheaper rate bands. Get an Agreement in Principle before you view — sellers and estate agents take an offer far more seriously when financing is already checked.

A £40,000 salary with a 10% deposit could support a simple illustrative £200,000 purchase on a 4.5× income multiple (£180,000 borrowed plus £20,000 deposit), subject to the lender's affordability assessment. Keep a buffer: stamp duty, surveys, solicitor fees and removals are cash costs on top of the deposit and vary by transaction.

Step 2: Making an Offer and Going Under Offer

Your offer is usually made verbally through the estate agent, then confirmed in writing. Until exchange of contracts, either side can walk away — there is no binding commitment, which is why "gazumping" (a seller accepting a higher offer later) remains legal in England and Wales. Once accepted, the property is marked under offer and the clock starts: your solicitor raises searches and enquiries, your lender values the property, and your survey is booked. Aim to keep the process moving because a slow buyer can be dropped for a faster chain.

Step 3: Stamp Duty Land Tax

SDLT is payable in England and Northern Ireland on purchases over the nil-rate threshold, with different rules for first-time buyers and additional properties. The bands are progressive — you only pay the higher rate on the slice of price within each band.

First-time buyers pay nothing up to £300,000 and 5% on the portion from £300,000 to £500,000 — the relief disappears entirely above £500,000, so a £510,000 purchase uses the standard rates on the full price. Buyers of additional properties usually pay 5 percentage points on top of the standard rates, and non-UK residents usually pay a further 2% in England and Northern Ireland. Scotland (LBTT) and Wales (LTT) have their own bands.

Step 4: Solicitor and Conveyancing

You need a conveyancing solicitor or licensed conveyancer to handle the legal transfer. Their job: check the title, raise searches (local authority, drainage, environmental, chancel repair), review the contract, calculate the SDLT return, and register the transfer at HM Land Registry. Fees typically run £850–£1,500 plus disbursements of roughly £300–£600 for searches, Land Registry fees and the SDLT filing. Compare quotes in writing, and expect them to flag anything from the searches — a planning application next door or a missing boundary — that you should chase before exchange.

Step 5: Surveys

The lender's valuation is for the lender, not you — it confirms the property is worth the loan, and it is not a survey. A condition report (Level 1) is a basic check; a homebuyer report (Level 2) covers structural issues for typical homes; a full structural survey (Level 3) is worth it for older, larger or non-standard properties. At £400–£1,500 depending on level and property size, a survey is the cheapest insurance you will buy in the process — a £700 survey that finds a £10,000 roof problem has paid for itself many times over.

Real Cost Examples

First-time buyer: £350,000 flat. Deposit 10% (£35,000). SDLT: nothing on the first £300,000, 5% on £50,000 = £2,500. Solicitor £1,200, Level 2 survey £650, searches and fees £450, removals £600. Total cash needed beyond the deposit: £5,400. Mortgage at 90% LTV on a simple 4.5× income multiple is £315,000, implying about £70,000 income before the lender's affordability assessment.

Home mover: £450,000 house. Under the standard rates, SDLT is 0% on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the remaining £200,000 (£10,000): £12,500 in total. With a £90,000 deposit (20%), the £360,000 mortgage is £80,000 at a simple 4.5× income multiple, before the lender's affordability assessment. A Level 3 survey at £1,100 on a 1930s property finds £8,000 of damp and re-pointing before exchange — the seller agrees to £5,000 off, easily covering the survey cost.

Hidden Costs to Budget

Beyond the headline items, buyers routinely forget a handful of smaller bills. A mortgage product fee of £999–£1,999 can sometimes be added to the loan rather than paid upfront — check whether the monthly cost of rolling it in is worth it. Buildings insurance must be in place from exchange, not completion, and home insurance before you move in. Valuation fees are waived by most lenders but not all. On a leasehold flat, budget for a share of the seller's ground rent and service charge statements, plus potentially a deed of covenant fee from the freeholder.

Add a contingency of £1,000–£2,000 on top of everything else — the survey that finds something, the searches that need chasing, the moving day that needs a second van. A 1% contingency of the purchase price is a sensible rule of thumb for older properties.

Exchange and Completion

Exchange of contracts is the point of no return: you pay the deposit (typically 10%), the completion date is set, and either side pulling out now forfeits money. Completion usually follows 1–4 weeks later, when the balance transfers, the keys release, and the property is legally yours. In Scotland the process differs — a binding contract forms much earlier at the conclusion of missives. Budget for the moving-day overlap: mortgage interest, insurance from exchange, and the first council tax bill all start at completion, not when you finally unpack.

Checks before exchange

Treat exchange as a decision gate, not just an administrative milestone. Confirm that the mortgage offer is still valid, the valuation matches the property and the lender has received any requested documents. Ask your conveyancer to explain unresolved searches, title restrictions, lease length, service-charge information, planning matters and any repair or insurance requirement. If the seller has agreed a price reduction or a repair, make sure it is reflected in the contract or completion arrangements rather than relying on a conversation with the estate agent.

Recalculate the cash required immediately before exchange. Include the deposit, SDLT, legal balance, searches, lender charges, insurance, removals and a contingency, and distinguish costs payable on exchange from those payable on completion. Do not assume that a first-time-buyer relief, higher-rate replacement-home refund or non-UK-resident surcharge applies until the buyer status and property facts have been checked against the current GOV.UK rules. A change in ownership, additional property or completion date can change the tax position.

Leasehold and new-build questions

For a leasehold property, review the lease term, ground rent provisions, service charge, planned major works, restrictions on subletting or alterations and the freeholder or managing-agent information. These are ownership obligations rather than mortgage headline figures. For a new build, check the specification, warranty, completion certificate, estate charges and whether the property is ready for legal completion. A reservation or developer incentive may affect the transaction economics and should be disclosed to the lender and solicitor.

Keep a written timeline of the offer, mortgage application, searches, survey, contract approval, exchange and completion. When a chain changes, update the timeline and ask which dates are contractual and which are only targets. This makes it easier to identify a genuine deadline, protect the mortgage offer and avoid committing to moving costs before the legal transaction is ready.
