Knowing what paperwork you’ll need can make the mortgage process far less stressful. Being prepared early helps avoid delays and gives lenders confidence in your application.

This guide explains the documents first-time buyers are usually asked for when applying for a mortgage in the UK.


Proof of Identity

Lenders need to confirm who you are.

You’ll usually need:

  • A valid passport or driving licence
  • Proof of address (such as a utility bill or bank statement)

Documents normally need to be recent and clearly readable.


Proof of Income

This helps lenders assess affordability.

Common examples include:

  • Recent payslips
  • P60
  • Employment contract
  • Bank statements showing salary credits

If you have variable income, lenders may ask for additional evidence.


Bank Statements

Most lenders request 3–6 months of bank statements.

They’ll review:

  • Regular income
  • Day-to-day spending
  • Existing financial commitments

This helps confirm affordability and financial behaviour.


Proof of Deposit

You’ll need to show where your deposit comes from.

This could include:

  • Savings statements
  • Gifted deposit letters
  • Evidence of funds building up over time

Transparency is important – lenders need to see the source of funds clearly.


Credit Commitments

Details of:

  • Loans
  • Credit cards
  • Finance agreements

These are often verified against your credit report.


Documents FAQs

What if I can’t find a document?

An adviser can usually suggest alternatives that lenders may accept.

Do documents need to be originals?

Most lenders accept digital copies, provided they are clear and complete.


Be Prepared and Apply With Confidence

Having your documents ready before you apply can make the mortgage process smoother and quicker.

If you’re unsure what you’ll need or want help preparing, a mortgage adviser can guide you through it step by step.
