Bank statements: what to review before you apply

In short

Bank statements are one of the ways the figures you give can be evidenced. Under the FCA's MCOB 11.6 responsible lending rules, a lender assessing affordability considers your income and your committed expenditure, must obtain evidence of income it takes into account, and may corroborate credit commitments using credit-reference searches or credit-card and bank statements; the rules give payslips and bank statements as examples of income evidence. MoneyHelper adds that lenders might ask to see recent bank statements to support the spending figures you supply, and that lender rules differ. Neither source sets a fixed number of months or a universal list of things a lender looks at, so what will be requested is a question for your lender or adviser.

Who this is for

  • Anyone about to gather statements for an application
  • People with irregular income or one-off credits they would need to explain
  • Applicants who want to describe their own finances accurately rather than from memory

Key points

Statements can evidence income and support declared spending

MCOB 11.6 lists bank statements among the examples of evidence of income, and MoneyHelper says lenders might ask to see recent bank statements to support the figures you have supplied for regular spending. That is the documented purpose: connecting your stated figures to your accounts.

Affordability is about income and committed expenditure

The FCA rules require affordability to be assessed against income and your committed expenditure, and allow firms to use either actual or modelled figures for some categories of household expenditure. So a lender's view of your outgoings is not necessarily built line by line from your statements.

Credit commitments may be corroborated in more than one way

MCOB 11.6 contemplates corroborating credit commitments using a credit-reference agency search or credit-card and bank statements. It does not require a lender to review all transactions individually, and we have not cited any source that says one does.

What is requested differs between lenders

Both MoneyHelper and the FCA rules leave the specifics to lender policy. No source cited here sets a number of months, a required file format, or a list of transaction types that will be examined.

Exceptions and things that vary

  • Requirements differ between lenders, including which accounts and how much history are requested. We cannot tell you a number, because no source cited here sets one.
  • Self-employed applicants may be asked about business as well as personal accounts; the specifics remain lender-set.
  • Joint applicants may be asked about individual accounts as well as shared ones; again this is lender policy.
  • Nothing here describes what any individual lender will look at, or how it will interpret what it sees.

How to work through it

  1. Ask what is actually needed

    Before exporting anything, ask your lender or adviser which accounts and what period they want, and in what format. That avoids guessing from a generic list.

  2. Obtain official statements for those accounts

    Download the statements your bank issues for the accounts and period you have been asked about, and keep them together in one place.

  3. Reconcile them against what you have declared

    Compare the income and regular spending figures you have given with what the statements show. Where the two differ, work out why, so you can describe your position consistently rather than from memory.

  4. Note factual errors and items you could not explain

    Flag anything that looks wrong — a duplicated debit, a payment you do not recognise — and anything, such as a one-off credit, you might be asked about. Being able to point to a receipt or transfer confirmation is the useful preparation.

  5. Write a short, truthful summary

    One page in your own words covering your income, your regular commitments and any one-off items, ready for a conversation with your lender or a qualified adviser.

Illustrative example (not a real case)

Imagine an applicant asked for statements for their main current account. Reading them, they notice they had described their travel costs as lower than the recurring payments actually show, and they see a one-off credit from selling a car. They correct the figure they had given and keep the sale invoice alongside the statement, so both points can be explained accurately. The example is about accuracy and organisation. It says nothing about what a lender would ask, look at, or decide.

Illustrative only. Figures and situations in examples are made up to show a method. They are not typical, not a benchmark and not a prediction of any outcome.

What not to assume

  • Do not assume a particular number of months, set of accounts or file format will be requested. Ask instead.
  • Do not assume being organised makes an application more likely to be accepted, or makes a decision quicker. It only means you can answer questions accurately.
  • Do not assume statements tell you anything about eligibility or the outcome of an application. They are evidence, not a decision.
  • Do not change, delay, reroute or disguise genuine spending or transfers in the hope of influencing a lender. Describe your finances as they actually are.
  • Do not assume moving money between your own accounts removes the need to explain where it came from.

Questions for a qualified adviser

We cannot answer these for you, and we do not introduce or recommend advisers. Take them to a suitably qualified FCA-authorised mortgage adviser of your own choosing.

  • Which accounts do you need statements for, for what period, and in what format?
  • Do the income and spending figures I have given match what you would expect to see?
  • How would you like me to evidence a one-off credit, such as a car sale or a refund?
  • Is there anything in what I have sent that you would like me to explain or obtain again?
