If you’re preparing to apply for a mortgage, having a clear mortgage checklist can make the process much smoother. Whether you’re a first-time buyer or applying for a new mortgage, this guide will walk you through the essential documents, key steps, and expert tips you’ll need for a successful mortgage application in the UK.

Before you meet a lender, it’s vital to use our checklist to make sure you’re fully prepared. Here’s your complete mortgage application checklist—designed to help you feel confident and ready for your mortgage journey.

Mortgage Application Checklist: Key Documents You Need to Provide

Before submitting any mortgage application, lenders will ask you to provide evidence of your income, identity, and finances. Here’s what you’ll need:

Personal Identification

  • Passport or driving licence
  • Proof of name and address (e.g. utility bill or council tax)

Income and Employment

  • Three months’ payslips
  • P60 form from your employer
  • Latest bank statements (usually covering 3–6 months)
  • For the self-employed: 2–3 years of SA302s from HMRC, tax year overviews, and business accounts

Credit & Financial Details

  • Credit report from one or more of the three credit reference agencies: Experian, Equifax, or TransUnion
  • Details of current loans, credit cards, and outgoings
  • Evidence of deposit (including source, e.g. someone gifting you the money)
  • If applying for a buy-to-let or investment property, you may need to provide additional documents

Mortgage Appointment Checklist: What to Bring

For your first appointment, whether in person or online, bring these documents you can bring to keep everything on track:

  • All ID and proof of address
  • Bank statements and payslips
  • Details of any ISA, savings, or investments
  • Proof of deposit source
  • Information on your desired mortgage term, repayment method (e.g. fixed-rate or interest-only), and property details
  • If you’re not a UK citizen: indefinite leave to remain, EEA residency, or an appropriate visa
  • If buying a second property, declare this upfront

Tip: The initial mortgage appointment is without obligation, so use it to gather insights and ask questions.

Choosing the Right Mortgage: Factors to Consider

Finding the right mortgage deal depends on your personal circumstances. Consider:

  • The best mortgage term for your lifestyle (e.g. 25 years)
  • Whether a fixed-rate or variable rate works best for you
  • LTV (loan-to-value ratio) and how your deposit affects the rate
  • Total monthly mortgage repayments and whether they fit your affordability
  • How quickly you want to repay the mortgage

This part of the mortgage application process can be complex. That’s why many buyers choose to work with trusted mortgage advisers who can assess your needs and find the best mortgage for your situation.

Check Your Credit History and Score

A strong credit history can improve your chances of a full mortgage approval. Before you apply, review your report and:

  • Make sure you’re on the electoral roll
  • Pay off any outstanding debts
  • Avoid new credit applications
  • Fix any inaccuracies with Experian, Equifax, or TransUnion

Improving your credit score could mean better rates and a quicker decision in principle.

Final Steps Before You Apply for a Mortgage

Here’s your final checklist to make sure you’re ready to get a mortgage:

  • Review your credit score and report
  • Gather all bank statements, payslips, and ID
  • Consider your ideal mortgage deal and repayment plan

  • Confirm how much you can borrow based on your income, outgoings, and deposit
