How to Buy a House in the UK: The Complete 2026 Guide

Buying your first home in the UK is the biggest financial decision most people ever make — and, if you have never done it before, one of the most confusing. This guide walks you through the entire process in 2026, in plain English and in the order it actually happens: working out what you can afford, saving your deposit, getting a mortgage agreed, making an offer, surviving conveyancing, and finally completing. Read it once from top to bottom and you will understand the whole journey; then use the linked deep-dive guides when you reach each stage.

In short: a typical first-time purchase takes roughly two to four months from accepted offer to completion, needs a deposit of at least 5% of the price plus a few thousand pounds in fees, and moves through nine clear stages. Here is each one.

Step 1: Work out what you can realistically afford

Before you fall in love with a listing, pin down your budget. Lenders typically offer around 4.5 times your annual income, though this varies with your outgoings, credit profile, and the size of your deposit. Your monthly mortgage payment, not just the headline price, is what determines whether a home is genuinely affordable. Factor in that interest rates in 2026 sit well above the lows of the early 2020s, so stress-test your budget against a rate a percentage point or two higher than today's.

Step 2: Save your deposit (and the hidden extras)

The deposit is the single biggest barrier for most first-time buyers. The minimum is usually 5% of the purchase price, but a larger deposit unlocks lower interest rates and cheaper monthly payments. Crucially, your deposit is not the only cash you need up front — budget separately for stamp duty (where it applies), conveyancing fees, a survey, mortgage arrangement fees, and removal costs.

• 5% deposit on a £250,000 home = £12,500 — the entry point for most 95% mortgages
• 10% deposit = £25,000 — noticeably better rates open up
• A Lifetime ISA adds a 25% government bonus on up to £4,000 saved each year
• Keep £2,000–£5,000 aside for fees, searches, survey and moving costs

Step 3: Get a mortgage Agreement in Principle

An Agreement in Principle (AIP), sometimes called a Decision in Principle, is a lender's written estimate of how much it would lend you, based on a soft credit check. It is not a full mortgage offer, but estate agents will rarely take your offer seriously without one — it proves you are a credible buyer. Getting an AIP early also flags any credit issues while you still have time to fix them.

Step 4: Find the right home and make an offer

Now the enjoyable part. Search with your maximum budget firmly in mind, view widely, and look beyond the decor to the fundamentals: location, condition, tenure, and running costs. When you find the one, you make an offer through the estate agent. Offers are not legally binding in England, Wales or Northern Ireland until contracts are exchanged, so both sides can still walk away — which is why the next steps move quickly.

Step 5: Apply for your full mortgage

With an offer accepted, you convert your Agreement in Principle into a full mortgage application. The lender runs a hard credit check, verifies your income and deposit, and instructs a valuation of the property to confirm it is worth what you are paying. If everything checks out, you receive a formal mortgage offer — usually valid for three to six months.

Step 6: Instruct a conveyancer and get a survey

Conveyancing is the legal process of transferring ownership. Your conveyancer or solicitor carries out local searches, checks the title and lease, raises enquiries with the seller's side, and handles the money. Separately, arrange a survey appropriate to the property's age and condition — a lender's valuation is not a survey and will not tell you whether the roof is failing.

Step 7: Exchange contracts

Exchange of contracts is the moment the purchase becomes legally binding. You pay your deposit to the conveyancer, a completion date is fixed, and neither party can pull out without serious financial penalty. This is also when you must have buildings insurance in place. Until exchange, you remain exposed to gazumping — a rival buyer offering more — so momentum matters.

Step 8: Completion day — you get the keys

On completion day the balance of the money is transferred, the seller moves out, and the estate agent releases the keys. The property is legally yours. Your conveyancer then files your Stamp Duty Land Tax return and registers you as the new owner with HM Land Registry. Congratulations — you are a homeowner.

“The single most common cause of a purchase collapsing is a broken chain further up or down the line. Understanding your chain — and choosing chain-free where you can — is one of the best ways to protect your move.”

How long does buying a house take?

From accepted offer to completion, a straightforward first-time purchase usually takes two to four months. Chains, slow searches, mortgage delays, or survey issues can extend that. Staying responsive to your conveyancer, returning paperwork the day it arrives, and keeping your mortgage broker in the loop are the practical levers that keep things moving.
