TL;DR

In short

  1. Work out a realistic budget, including the deposit, purchase costs and a margin for ongoing ownership costs.
  2. A mortgage agreement in principle (AIP) can help with your search, but it is provisional; a full application and further lender checks follow.
  3. After an offer is accepted, mortgage, survey and legal work can overlap. The point at which a purchase becomes binding differs across the UK.
  4. England and Wales, Scotland, and Northern Ireland have different legal stages and property taxes. Get advice from the professionals handling your transaction.

Buying a home is a major financial and legal commitment. This guide outlines a typical owner-occupied purchase, from planning your budget to completion or settlement. The order can overlap, and neither a mortgage nor a purchase offer is guaranteed.

How to buy a house in the UK: a practical sequence

1. Set a realistic budget and prepare for lender checks

Start with what you can afford each month, not only the price you would like to pay. A lender may consider your income, regular commitments, household expenditure, deposit, the property and its own lending criteria. Your credit-report information can be relevant, but a consumer credit score does not guarantee a mortgage approval or a particular rate.

Check your credit files for accuracy and allow time to address any issues. You can obtain your statutory credit report without paying for a subscription. If you choose a paid monitoring service, check its current trial length, renewal price and cancellation terms first. This Checkmyfile link is an affiliate link, so Extend Finance may receive a commission if you use it.

Gather documents a lender may request, such as identification, evidence of income, outgoings and the source of your deposit. You may then seek an agreement in principle (AIP), also called a mortgage in principle. An AIP is an early indication based on limited information; it is not a mortgage offer, and a lender will carry out further checks before deciding whether to lend.

Non-British applicants may have mortgage options, but eligibility can depend on the lender’s residency, visa and other criteria. Owning a property does not itself establish permission to live in the UK.

2. Build a deposit and budget for separate costs

Deposits commonly start at around 5% to 10%, but there is no universal minimum: products, applicants and properties have different criteria. Some limited low- or no-deposit products exist. For example, Skipton’s Track Record options are advertised for England, Wales and Scotland, not Northern Ireland, and are subject to its eligibility criteria. A larger deposit can improve loan-to-value and available pricing; where rate, term and repayment basis are the same, borrowing less reduces the scheduled payment.

Use local property listings, such as Rightmove and Zoopla, to test your target price. Dividing the price by 20 is only a 5% deposit illustration, not a rule for every mortgage.

Keep the deposit separate from an itemised buying budget. Ask for quotes and leave a contingency for costs that apply to your transaction, including:

  • solicitor or conveyancer fees, searches and registration costs;
  • a lender valuation, mortgage product or application charges where applicable;
  • an independent condition survey, if you choose one;
  • purchase tax, moving costs, buildings insurance and any immediate repairs; and
  • continuing costs such as mortgage payments, maintenance and household bills.

Purchase tax is not one UK-wide charge. Stamp Duty Land Tax (SDLT) applies in England and Northern Ireland, Land Transaction Tax (LTT) applies in Wales, and Land and Buildings Transaction Tax (LBTT) applies in Scotland. Some buyers owe no purchase tax, while reliefs, higher rates and other circumstances can change the result. Check the relevant tax authority’s current guidance for your circumstances.

3. Decide whether to use a mortgage adviser

You can apply to a lender directly or use a mortgage adviser. An adviser can help explain options, prepare a mortgage application and work within the range of lenders and products they cover. Ask how the adviser is paid, whether there is a fee or commission, what its lender/product coverage is, and how total cost and suitability will be considered. Even a whole-of-market service may not include every deal.

A mortgage adviser supports the mortgage process; a solicitor or conveyancer handles the legal transfer. If you use a firm for regulated financial services, you can check its relevant permissions on the FCA Financial Services Register.

4. Find a property and make an offer

Compare properties carefully: location, tenure, condition, likely repair needs and your own priorities all matter. An estate agent can pass on your purchase offer, but a purchase offer is different from a mortgage offer. You can make an offer before receiving a final mortgage decision, but plan the finance, survey and legal work before you become legally committed.

Once an offer is accepted, instruct a solicitor or conveyancer promptly. The formal process then varies by nation, so use the correct section below and ask your legal professional about your contract, conditions and insurance timing.

After you have chosen a property, submit the formal mortgage application if you have not already done so. The lender may value the property for its own lending decision. That valuation is not the same as a buyer’s condition survey: a survey can give you more information about the property’s condition and may identify work you need to budget for.

At the same time, your solicitor or conveyancer carries out the legal work. They can investigate title, obtain searches where relevant and explain the contract and conditions. Do not treat an AIP, an accepted purchase offer or a lender valuation as confirmation that the transaction will complete. Confirm that mortgage funding and the contract conditions are satisfactory before committing, following your solicitor’s advice.

6. Know when the purchase becomes binding

England and Wales

In an ordinary private-treaty purchase, an accepted offer is usually subject to contract. The purchase becomes binding on exchange of contracts; completion follows, when funds are transferred and keys are released. Auctions and new-build contracts can follow different arrangements. Legal checks and searches, a lender valuation and a buyer’s survey are separate steps. Ask your solicitor when buildings insurance should start, because the timing can depend on the contract, property and lender requirements.

Scotland

In Scotland, a solicitor submits the formal offer. A qualified acceptance and negotiated missives come before a binding contract when missives are concluded, so confirm finance and conditions with your solicitor before that point. A Home Report normally includes a survey/valuation, property questionnaire and energy report, though exemptions exist, including for some new homes; it does not necessarily replace other checks or lender requirements.

The solicitor checks title and title burdens, then handles settlement, usually on the agreed date of entry, with funds, disposition and keys. Registration follows the relevant legal process. Ask your solicitor when insurance risk transfers under the missives and whether any block policy applies.

Northern Ireland

In Northern Ireland, engage your own solicitor, arrange mortgage finance and obtain condition checks that are appropriate for the property. A condition survey is separate from a lender valuation. Contracts are exchanged when the purchase becomes binding, followed by completion through transfer of funds and possession. Contract terms and timing vary, so have your solicitor confirm the position for your purchase and the appropriate insurance timing.

Is buying right for you?

Buying can suit people who want to make a long-term home and can afford the costs and risks, but it is not automatically better than renting. Renting provides accommodation and flexibility; buying brings legal ownership alongside borrowing, maintenance and transaction costs.

With a repayment mortgage, the capital part of each payment reduces the debt; interest-only payments do not repay the principal. Property prices can fall, which can leave an owner in negative equity, and maintenance or repairs remain the owner’s responsibility. Fixed mortgage payments normally stay unchanged during the fixed deal period, while variable payments may change and payments can also change when a fixed deal ends. Build affordability headroom and consider how you would manage changes in your circumstances.

Home improvements may also need planning or building approvals and can be limited by title, lease or local rules. Check the applicable requirements and get professional advice before committing to work.

Your home may be repossessed if you do not keep up repayments on your mortgage.

FAQ

Frequently asked questions

How much deposit do I need to buy a house in the UK?

Deposits commonly start at around 5% to 10%, but this is not a universal minimum. The deposit and product available depend on the lender’s criteria, your circumstances and the property. Budget separately for the deposit and buying costs.

What is the difference between an AIP and a mortgage offer?

An AIP is a provisional indication based on limited information. A mortgage offer follows a formal application and further lender checks; neither an AIP nor an accepted purchase offer guarantees completion.

Is a mortgage valuation the same as a house survey?

No. A lender valuation helps the lender make its lending decision. A buyer’s condition survey is a separate check that can provide more information about the property’s condition.

When does a house purchase become legally binding?

For an ordinary private-treaty purchase in England and Wales, this is usually exchange of contracts. In Scotland, it is when missives are concluded. In Northern Ireland, contracts are exchanged. Your solicitor can explain the exact point and any exceptions for your transaction.

Which taxes and costs should I budget for?

Budget from quotes for legal work, searches, registration, lender charges where applicable, survey, moving, insurance, repairs and ongoing costs. SDLT applies in England and Northern Ireland, LTT in Wales and LBTT in Scotland; liability and any relief depend on your circumstances.
