The UK home buying process — a first-time buyer's complete guide

Buying a home in the UK — the full picture

Buying your first home is one of the largest financial decisions you'll make. In the UK the process has several distinct stages — getting financially ready, securing an Agreement in Principle, finding a property, making an offer, applying for a mortgage, instructing a conveyancer, commissioning a survey, exchanging contracts and finally completing.

This guide walks through every stage in plain English: deposit and credit prep, schemes you may qualify for, mortgage applications, conveyancing, surveys, costs to budget for, and what happens on completion day.

MortgagePath does not give regulated mortgage advice. The aim is to help you arrive at a broker or solicitor conversation already understanding the language.

1. Getting financially ready

Before you start viewing properties, lenders will want to see that your finances are in order. The single biggest predictor of how smoothly your application runs is preparation in the months beforehand.

• Build your deposit. UK mainstream lenders typically accept deposits from 5% of the property price, though 10–15% generally opens more competitive products.
• Check your credit reports. The three main UK credit reference agencies are Experian, Equifax and TransUnion. You can access free reports through services such as ClearScore, Credit Karma and Check My File. Look for missed payments, hard searches, electoral roll status and any old addresses still on file.
• Reduce credit utilisation. Try to keep credit card balances below ~30% of the available limit in the months before applying.
• Avoid new credit. Don't take out a car loan, buy-now-pay-later or new credit cards in the 3–6 months before applying — every search and new line of credit can affect affordability.
• Keep bank statements clean. Lenders look at 2–3 months of statements. Frequent gambling transactions, unarranged overdrafts, or unexplained large transfers can all cause questions.
• Stabilise employment. Most lenders prefer to see at least 3 months in your current role; self-employed applicants usually need 2 years of accounts or SA302s.

2. Government schemes and savings products

Several UK schemes exist to help first-time buyers. They change over time, so always confirm current rules on gov.uk before relying on them.

3. How much could I borrow?

Most UK lenders work out a maximum loan as a multiple of your gross household income, then adjust for outgoings.

As a rough rule of thumb, lenders apply income multiples between 4× and 4.75× combined gross income. Some lenders go higher (5–5.5×) for higher earners, professionals (medics, lawyers, accountants), or specific schemes; others go lower if you have dependants or significant credit commitments.

After the income multiple, lenders run an affordability assessment that subtracts modelled household bills, credit commitments, childcare, and stress-tested mortgage payments (often based on a rate 1–3 percentage points above the actual product rate).

• Salary, regular overtime, shift allowances, and bonuses can usually be included (typically at 50–100% depending on regularity).
• Self-employed income is normally averaged over 2 years of tax returns or company accounts.
• Benefits such as Child Benefit and tax credits are accepted by many lenders, but policies vary.
• Pension income, rental income and trust income each have specific rules — a broker can map which lenders treat each favourably.

4. Agreement in Principle (AIP)

An Agreement in Principle — sometimes called a Decision in Principle or Mortgage in Principle — is a non-binding indication from a lender that they may be willing to lend a certain amount, based on a soft credit check and the figures you've shared.

An AIP is not a mortgage offer. It usually lasts 30–90 days and exists to help estate agents and sellers take your offer seriously. The full mortgage application that follows includes a hard credit search, document evidence, and underwriter review.

If a lender or broker uses a soft search at the AIP stage, your credit file should not be affected. Always ask whether the search will be soft or hard before consenting.

5. Finding a property and making an offer

Once your AIP is in hand and you understand your budget, the property search begins. UK buying is typically through estate agents listing on Rightmove, Zoopla and OnTheMarket.

• View properties more than once where possible — different times of day reveal different things (light, noise, parking, neighbours).
• Ask the agent about lease length (if leasehold), service charge / ground rent, EPC rating, council tax band, and any planned works.
• Offers in England, Wales and Northern Ireland are not legally binding until exchange. In Scotland the system differs — an accepted offer through your solicitor is usually binding much earlier.
• If your offer is accepted, the property should be marked 'Sold Subject to Contract' (SSTC). The clock now starts on conveyancing, mortgage application and survey.

6. The full mortgage application

With an offer accepted, you move from AIP to a full mortgage application. This is where the underwriter reviews everything in detail.

• Expect to provide: photo ID, proof of address, the last 3 months of payslips and bank statements, P60, and SA302s (if self-employed).
• The lender will run a hard credit search at this stage.
• The lender will also instruct a property valuation — see the Valuation section below — which is separate from your survey.
• If approved, you receive a binding mortgage offer (usually valid 3–6 months). Read it carefully — once you exchange contracts you're committed.

7. The lender's valuation (this is not a survey)

The lender's valuation is a brief inspection (sometimes a desktop check) carried out for the lender, to confirm the property is worth at least the amount they're being asked to lend against.

It is performed for the lender, not for you. It produces a one-line opinion of value, not a structural assessment, and you may never see the full report. Do not rely on the lender's valuation to tell you about the condition of the property — that is what a survey is for.

Many lenders fund a basic valuation as part of the product; others charge a fee. A 'down-valuation' (lender values the property below the agreed sale price) can mean renegotiating the price, putting in extra deposit, or — occasionally — losing the deal.

8. Conveyancing — the legal side

Conveyancing is the legal work that transfers ownership of the property from the seller to you. It is completely separate from the survey, and is carried out by a licensed conveyancer or a solicitor who is qualified to do property work.

Your conveyancer represents your legal interest. The seller has their own conveyancer. The two sides exchange information, raise enquiries, conduct local searches, agree the contract, exchange contracts on an agreed date, and finally complete the transfer of funds and ownership.

• Typical conveyancing cost in 2026: ~£900–£1,800 in legal fees plus disbursements (searches usually £250–£500, Land Registry, SDLT submission).
• Choose a firm regulated by the SRA (Solicitors Regulation Authority) or the CLC (Council for Licensed Conveyancers).
• Online vs. local: online firms are often cheaper and quicker on simple freehold transactions; complex chains, leasehold or unusual properties can benefit from a local solicitor.

9. Surveys — checking the property's condition

A survey is a physical inspection of the property by a qualified surveyor — typically RICS-regulated. It is paid for by you, performed for you, and tells you about the building's condition. It is completely separate from the lender's valuation and from the legal conveyancing work.

The Royal Institution of Chartered Surveyors (RICS) defines three standard levels of survey. Choose the level that matches the property's age, condition and your appetite for surprises after moving in. New-builds usually have a separate 'snagging' inspection instead.

• Always confirm the surveyor is RICS-regulated and has professional indemnity insurance.
• Reading the survey: focus on defects rated 'urgent' or 'significant'. Quotes for those works should inform any renegotiation with the seller.
• If the survey reveals major issues you didn't expect, you can renegotiate the price, ask the seller to fix items pre-completion, or — because nothing is binding until exchange — withdraw.

10. Exchange of contracts

Exchange is the legally binding moment. Both sides sign identical contracts; your conveyancer transfers the deposit; a completion date is fixed.

From the moment of exchange, neither party can walk away without significant financial consequences. This is why your mortgage offer, buildings insurance, deposit funds and surveys all need to be in place before exchange — not after.

You will normally need buildings insurance to start from the date of exchange (not completion), because legally you carry the risk on the property from this point.

11. Completion day

On the agreed completion date, your conveyancer sends the balance of the purchase price to the seller's conveyancer. Once funds are confirmed received, the estate agent releases the keys.

• Keys are usually available from late morning / early afternoon on completion day.
• Your conveyancer registers the transfer with HM Land Registry and submits the SDLT/LBTT/LTT return.
• Your first mortgage payment is normally due the following month, with a slightly higher first payment to cover interest from completion date to the first regular payment date.

12. Costs to budget for (beyond the deposit)

Many first-time buyers under-estimate the 'extras'. Build a buffer into your savings plan.

• Stamp Duty Land Tax (or LBTT in Scotland, LTT in Wales) — first-time buyer relief may apply up to set thresholds. Confirm on gov.uk.
• Conveyancing fees and disbursements — typically £1,200–£2,500 all-in.
• Survey — £250–£1,500+ depending on level.
• Mortgage arrangement / product fee — sometimes added to the loan; often £495–£1,500.
• Mortgage broker fee — some brokers are fee-free, others charge ~£295–£995.
• Removals — £400–£1,500 typically, more for long-distance or large homes.
• Buildings insurance — required from exchange. Contents insurance recommended.
• Immediate setup costs — utilities, council tax, broadband, locks/keys, basic furniture and white goods.

13. After you move in

The job isn't quite done when the kettle is on. A few admin tasks in the first weeks save trouble later.

• Take meter readings on completion day and register with utility suppliers.
• Inform your local council you've moved in (council tax).
• Register on the electoral roll at your new address.
• Update DVLA (driving licence and V5C for any vehicles), HMRC, your employer, banks, GP and insurance providers.
• Test smoke alarms, CO alarms and locate the stopcock, fuse board and gas meter.
• Save digital copies of the TA6/TA10 forms, completion statement, mortgage offer and survey for future reference.

14. Energy and ongoing running costs

Running costs vary widely between properties. Check the EPC rating, the heating system age, insulation levels and window quality before you offer.

Most UK homes use gas combi or system boilers; many newer homes use air-source heat pumps. EPC bands run A (most efficient) to G (least efficient); the EPC certificate also gives indicative annual heating costs and recommended improvements.

Switching energy supplier on day one is one of the easier wins. Some suppliers offer sign-up credits.
