How to Get a Mortgage in the UK: Complete Guide 2026

Getting a mortgage is the biggest financial transaction most people in the UK will ever make. Understanding how the process works — and how to give yourself the best chance of approval at the best rate — is essential before you start your property search.

How Much Can You Borrow?

Most UK lenders use an income multiple to determine the maximum mortgage. The standard is **4.5 times gross annual income**. Some lenders will go to 5 or 5.5 times for borrowers in certain professions (doctors, lawyers, accountants) or with low outgoings.

For joint applications, lenders typically use a multiple of combined income.

**Example:** Two applicants earning £35,000 each (£70,000 combined) could borrow up to £315,000 at 4.5x income.

Deposit Requirements

The minimum deposit for a residential mortgage is 5% of the purchase price. However:

• **5% deposit (95% LTV):** Higher rates, fewer products available
• **10% deposit (90% LTV):** Significantly better rates
• **25% deposit (75% LTV):** Access to market-leading rates
• **40% deposit (60% LTV):** Best rates on the market

The bigger your deposit, the lower the risk to the lender and the lower the interest rate you will be offered.

What Lenders Assess

Lenders conduct a full affordability assessment which goes beyond income multiples:

Credit Score and History

Your credit file is checked with one or more of the main agencies (Experian, Equifax, TransUnion). Lenders look for:

• No missed payments in the last 3 years
• No County Court Judgements (CCJs)
• No bankruptcies or IVAs
• Low utilisation of existing credit

Check your credit file with all three agencies before applying. Errors are common and can be corrected.

Income Verification

Employed applicants provide:

• Last 3 months’ payslips
• Most recent P60
• Bank statements showing salary credits

Self-employed applicants typically need:

• 2–3 years’ SA302 tax calculations (from HMRC)
• 2–3 years’ accounts (prepared by an accountant for most lenders)

Outgoings and Commitments

Lenders stress-test your ability to repay at higher rates and deduct committed outgoings (other loans, car finance, child maintenance) from disposable income.

The Application Process

Step 1: Get a Decision in Principle (DIP)

A DIP (also called Agreement in Principle or Mortgage in Principle) is a conditional confirmation that a lender would lend you a certain amount. It involves a soft credit check (no impact on your score with most lenders) and takes 24–48 hours.

Get a DIP before you start making offers on properties. It shows sellers and agents you are a serious buyer.

Step 2: Instruct a Mortgage Broker or Apply Direct

A whole-of-market mortgage broker searches all lenders on your behalf and can access some deals not available to consumers directly. For most buyers, using a broker is the most efficient route.

Step 3: Full Application

Once your offer on a property is accepted, submit the full mortgage application with:

• Payslips and P60 (or accounts for self-employed)
• Bank statements (last 3 months)
• Photo ID and proof of address
• Details of the property (from the estate agent)
• Solicitor details

Step 4: Valuation

The lender arranges an independent valuation of the property (or an automated desktop valuation for lower-risk cases). This is not a survey — it confirms the property is worth the amount you are borrowing.

Step 5: Formal Mortgage Offer

If the application is approved, the lender issues a formal mortgage offer. This is valid for 3–6 months. Your solicitor will receive a copy.

Step 6: Exchange and Completion

Your solicitor will arrange for the mortgage funds to be drawn down on completion day. The lender transfers the money directly to the seller.

How to Improve Your Mortgage Chances

Before applying:

• Check and correct your credit file with all three agencies
• Register on the electoral roll if you are not already
• Avoid new credit applications in the 3 months before your mortgage application
• Reduce credit card balances to below 30% of the credit limit
• Avoid large unexplained deposits in your bank account (lenders ask about these)
• Save a larger deposit if possible — each LTV band improves available rates

Mortgage Costs to Budget For

Beyond the deposit:

• **Arrangement fee:** £999–£2,000 (can be added to the mortgage but you pay interest on it)
• **Valuation fee:** £150–£500 (often free on packaged products)
• **Solicitor fees:** £900–£1,600
• **Broker fee:** £0–£500 (most brokers are free to the buyer)
• **Stamp duty:** Varies by price and buyer type
