What documents do I need for a mortgage application?

Last reviewed 19 May 2026 · Smarter Mortgage Quotes editorial team

Most application delays are documents — a missing payslip or an out-of-date utility bill can hold up an offer by a week. This is the checklist worth printing.

Everyone

  • Photo ID — UK passport or driving licence.
  • Proof of address — utility bill, council tax, bank statement (last 3 months).
  • Proof of deposit — bank statements showing the source and any gift letter.
  • Last 3 months of personal bank statements.

If employed

  • Last 3 months’ payslips.
  • Latest P60.
  • If you receive regular bonus / commission — last 2 years of payslips or P60s.

If self-employed

  • Last 2 years SA302 (tax calculation) from HMRC.
  • Tax year overview for the same 2 years.
  • Certified accounts (Ltd directors).
  • Accountant’s reference (some lenders).
  • Business bank statements (last 3 months).

If remortgaging

  • Current mortgage statement (within the last 12 months).
  • Buildings insurance schedule.
  • Any property improvements done that may affect valuation.

Get these together before you apply and you can shave weeks off the timeline.
