How to Get a Mortgage in UK (First-Time Buyers Guide

Buying your first home in the UK is an exciting milestone, but the process of getting a mortgage can feel overwhelming—especially if you’re new to it. With different lenders, deposit requirements, and affordability checks, understanding how mortgages work is essential before making any decisions.

This guide will walk you through everything first-time buyers need to know about getting a mortgage in the UK in 2026, from saving for a deposit to getting approved.

What is a Mortgage?

A mortgage is a type of loan used to buy property. You borrow money from a lender (usually a bank or building society) and agree to repay it over time—typically between 25 to 35 years—with interest.

The property itself acts as security, which means if you fail to repay, the lender can repossess your home.

Step 1: Check Your Financial Situation

Before applying for a mortgage, you need to understand your financial position. Lenders will assess:

Your income
Monthly expenses
Existing debts
Credit history

Most lenders follow strict affordability checks to ensure you can manage repayments even if interest rates rise.

A good rule is that lenders may offer 4 to 4.5 times your annual income, although this can vary depending on your circumstances.

Step 2: Save for a Deposit

The deposit is the upfront payment you make towards your property. In the UK, most first-time buyers need at least:

5% deposit (minimum requirement)
10–20% deposit (better mortgage deals)

For example, if you’re buying a £250,000 home:

5% deposit = £12,500
10% deposit = £25,000

The bigger your deposit, the lower your interest rate and monthly repayments.

Step 3: Improve Your Credit Score

Your credit score plays a crucial role in mortgage approval. A higher score increases your chances of getting better deals.

To improve your credit score:

Pay bills on time
Avoid missing payments
Reduce existing debts
Register on the electoral roll

Lenders use your credit history to determine how reliable you are as a borrower.

Step 4: Get a Mortgage Agreement in Principle (AIP)

An Agreement in Principle (also called a Decision in Principle) is a statement from a lender showing how much they might lend you.

This is not a full mortgage offer, but it helps you:

Understand your budget
Show sellers you are a serious buyer
Speed up the buying process

Most estate agents prefer buyers who already have an AIP.

Step 5: Understand Types of Mortgages

There are different types of mortgages available in the UK. The most common include:

1. Fixed-Rate Mortgage

Your interest rate stays the same for a set period (usually 2, 3, or 5 years).
Best for: Stability and predictable payments

2. Variable-Rate Mortgage

Interest rates can go up or down depending on the lender or Bank of England base rate.
Best for: Flexibility but comes with risk

3. Tracker Mortgage

Follows the Bank of England base rate plus a fixed percentage.
Best for: Transparent rate changes

4. Discount Mortgage

Offers a discount on the lender’s standard variable rate for a limited time.

Choosing the right type depends on your risk tolerance and financial stability.

Step 6: Compare Mortgage Deals

Not all mortgages are the same. You should compare:

Interest rates
Fees (arrangement, valuation, legal)
Cashback or incentives
Early repayment charges

Using a mortgage broker can help you find better deals, especially if your situation is complex.

Step 7: Submit Your Mortgage Application

Once you’ve chosen a lender, you’ll need to submit a full application. This includes providing documents such as:

Proof of income (payslips, tax returns)
Bank statements
ID and address verification
Details of the property

The lender will then carry out:

Credit checks
Affordability assessment
Property valuation

Step 8: Receive a Mortgage Offer

If your application is successful, the lender will issue a formal mortgage offer. This document outlines:

Loan amount
Interest rate
Repayment terms
Conditions

At this stage, you can proceed with the legal process (conveyancing) and finalize your home purchase.

Step 9: Complete the Purchase

After legal checks are completed, contracts are exchanged, and you’ll set a completion date. On this day:

The lender releases funds
You pay your deposit
Ownership of the property is transferred to you

Congratulations—you are now a homeowner!

Additional Costs to Consider

Buying a home involves more than just a deposit. You should budget for:

Stamp Duty (first-time buyers may get relief)
Solicitor fees
Survey and valuation costs
Moving expenses

Planning for these costs will prevent financial surprises.

Government Schemes for First-Time Buyers

The UK government offers schemes to help buyers get on the property ladder:

1. Shared Ownership

Buy a portion of a property and pay rent on the rest.

2. Lifetime ISA (LISA)

Save up to £4,000 per year and receive a 25% government bonus.

3. First Homes Scheme

Offers discounts on new-build homes for eligible buyers.

These schemes can make homeownership more affordable.

Tips for First-Time Buyers

To improve your chances of success:

Save as much deposit as possible
Avoid taking new loans before applying
Keep your financial records organized
Work with a mortgage broker
Don’t rush—compare multiple options

Being prepared can make the entire process smoother and less stressful.

Common Mistakes to Avoid

First-time buyers often make these mistakes:

Borrowing more than they can afford
Ignoring additional costs
Not checking credit score
Choosing the wrong mortgage type
Skipping professional advice

Avoiding these errors can save you money and stress in the long run.
