What Documents Do I Need to Apply for a Mortgage?

Applying for a mortgage can feel overwhelming, but being well-prepared with the right paperwork puts you in a strong position and helps things move smoothly. Here is a comprehensive guide on the key documents you should gather before you apply.

The Key Mortgage Documents You'll Need

When you apply for a mortgage in the UK, most lenders will ask for the following documents: Having these ready in advance can make the whole process quicker and smoother.

1. Proof of Identity and Address

What you need:

• A valid passport, driving licence, or other government-issued photo ID

• A proof of address document, such as a council tax bill, utility bill, or bank statement from the last three months

Why it matters: Lenders must verify who you are and where you live to comply with money-laundering regulations. Having all details up to date prevents delays.

2. Proof of Deposit

What you need:

• Bank statements showing your savings (typically one to three months)

• If your deposit is a gift, you will need a gift letter confirming it is non-repayable

Why it matters: Lenders want to ensure your deposit funds are transparent and legitimate.

3. Proof of Income

For Employed Applicants:

• Pay slips (typically last three months, or up to six if you are paid weekly)

• A P60 or annual statements for bonuses, overtime, or commission

For Self-Employed Applicants:

• SA302 tax forms and tax-year overviews from HMRC (usually two years’ worth)

• Year-to-date business accounts or certified accounts if you own a limited company

• Up to 24 months of business bank statements, and interim accounts if trading for less than two years

Why it matters: It demonstrates to the lender that you have a steady earned income and verifies your affordability.

4. Proof of Expenditure

Required documents:

• Statements of regular payments like rent, loan repayments, and credit cards

• Evidence of ongoing commitments, such as insurance or maintenance payments

Why it matters: Lenders assess your ability to afford repayments alongside existing outgoings.

5. Additional Income Sources

You may also need to document other income, like:

• Benefits (Universal Credit, child tax credits) with three months’ bank statements or award letters

• Pensions or foster allowances withthe latest statement or payment summary

• Investment income or rental income with the latest statements

Why it matters: Every verified income source boosts your affordability and borrowing power.

6. Non-UK or Foreign Nationals

If you are not a UK citizen or have lived abroad recently, you will need:

• A valid visa or residence permit, or a ShareCode confirmation

• Non-UK credit history if in the UK for less than 12 months

Why it matters: Lenders need proof of lawful UK residence and may check overseas credit history where applicable.

7. Other Property Details (for purchases and remortgages)

You may also be asked for:

• Valuation reports or RICS survey summary (for buy-to-let or remortgage scenarios)

• Solicitor or estate agent details, plus information about lease length or block management if applicable
