What documents do I need for a mortgage in the UK?

Most UK lenders ask for photo ID, proof of address, proof of income and recent bank statements. Employed applicants usually supply three months of payslips and a recent P60. Self-employed applicants usually supply two to three years of SA302 tax calculations with matching tax year overviews, or company accounts. You will also need evidence of your deposit and, if you are remortgaging, a recent mortgage statement.

How many bank statements do mortgage lenders want?

Three months is the common request, and six months is not unusual for self-employed applicants, contractors, or anyone with a less standard income pattern. Lenders look at your regular commitments and spending patterns, not at individual purchases, so send complete statements rather than edited ones.

Do I need documents before I get an agreement in principle?

Usually not. An agreement in principle is normally based on figures you declare plus a credit check. Documents get checked at full application, which is when a mismatch between what was declared and what the paperwork shows causes problems. Gathering the file early is the simplest way to avoid that.

What counts as proof of deposit?

Typically savings statements showing the money and how it built up. A gifted deposit usually needs a letter from the person gifting it confirming it is a gift rather than a loan, plus ID and evidence of where their money came from. Lenders are meeting anti-money-laundering obligations, so unexplained lump sums attract questions.

Mortgage Documents Checklist (UK)

Plain-English guide · no advice, just how the market works

Mortgage applications rarely fall over because someone lacked a document. They fall over because the document arrived three weeks late, or said something different from the application form. Assembling the file before you apply is the cheapest thing you can do to make the process fast, and it costs you nothing but an evening.

The universal four

Almost every lender, for almost every applicant, wants these.

1. Photo ID

A valid passport or a photocard driving licence. It needs to be in date and the name needs to match the application, so if you have married, divorced or changed your name, sort the deed poll or marriage certificate out now rather than at underwriting.

2. Proof of address

Usually a utility bill, council tax bill or bank statement from the last three months. Mobile phone bills are often rejected. If you have moved recently, expect to evidence the last three years of address history on the form even though you only prove the current one.

3. Proof of income

What this means depends entirely on how you are paid, which is the next section.

4. Bank statements

Three months is the standard ask, six is common for anything less conventional. Send full statements, every page, unedited. Underwriters are looking at committed outgoings, existing credit, and whether the income landing in the account matches the payslips. They are not scrutinising your takeaway habit, but undeclared loan repayments and gambling transactions do get noticed.

Proof of income, by how you earn

Employed

Typically the last three months of payslips and your most recent P60. If a meaningful part of your income is bonus, overtime or commission, expect to be asked for longer evidence, often payslips covering a year or two, because lenders differ enormously in how much variable pay they count. That variation is precisely the kind of thing a broker is paid to know.

Self-employed, sole trader or partnership

Usually two to three years of SA302 tax calculations with the matching tax year overviews, both downloadable from your HMRC online account. One without the other is routinely rejected, so always pull the pair for each year.

Company director

Usually two to three years of finalised accounts prepared by an accountant, plus personal tax documents. Whether a lender considers salary plus dividends, or salary plus your share of retained profit, varies by lender and can change the borrowing figure substantially. Our self-employed broker page goes into who reads those accounts generously.

Contractor

Often a copy of the current contract, evidence of the contracting history, and business bank statements. Several lenders will work from a day rate rather than accounts, which frequently produces a very different answer.

Other income

Rental income, pensions, maintenance, benefits and second jobs are all treated differently by different lenders. Declare everything, evidence what you can, and let the broker work out who counts it.

Deposit and the money-laundering question

Lenders must establish where your deposit came from. Savings built over time are simple: statements showing the balance and the pattern. A lump sum that appears from nowhere will be queried, so be ready to evidence a house sale, an inheritance, a bonus or a share sale.

A gifted deposit normally needs a letter from the giver stating that it is a gift and not repayable and that they retain no interest in the property, together with their ID and evidence of their own source of funds. Ask for this early. Chasing a relative for a passport scan during a chain is nobody’s idea of a good week.

Extra documents for particular cases

Remortgaging: a recent mortgage statement and, if the property is let, the tenancy agreement.
Buy-to-let: evidence of rental income or a letting agent’s appraisal, plus details of your existing portfolio. See our buy-to-let guide.
New build: the reservation form and details of any builder incentives, which affect the valuation.
Shared ownership or Right to Buy: the memorandum of sale or offer notice from the housing association or council.
Visa holders: your visa or share code, and evidence of time in the UK.
Credit history with blemishes: nothing extra is compulsory, but a short written explanation of what happened and when often helps. Our credit history page covers this.

How to assemble the file once

Create one folder, digital, named with the year.
Download statements as PDFs from your banking app rather than photographing paper, screenshots and photos of screens get rejected constantly.
Pull SA302s and tax year overviews together, year by year.
Check every name and address is consistent across every document.
Check nothing expires in the next three months.

Do this once and you can apply, re-apply to a different lender, or switch mid-process without losing a fortnight.

Why the list changes between lenders

There is no national mortgage document standard. Each lender sets its own underwriting policy, which is why one will accept a contractor’s day rate and another insists on two years of accounts, and why a case that was declined on paperwork grounds in one place sails through elsewhere. Matching your circumstances to the lender whose policy fits is most of what a good broker does. If you want to understand the wider job, read do I need a mortgage broker.
