Mortgage application documents: the full checklist

Most UK mortgage applications need the same core set: photographic identity, proof of address, three months of payslips and bank statements, your latest P60, and evidence of where your deposit came from. Self-employed applicants add two to three years of tax calculations and tax year overviews or accounts. Contractors add their current contract. Gifted deposits need a signed letter from the donor. Requirements vary by lender, so treat this as the working list rather than a fixed rule.

Lenders must verify who you are. Many can do this electronically against the electoral roll and credit data, in which case you may never be asked for anything. If the electronic check fails, which is common if you have recently moved or are not registered to vote, you will need documents.

• A valid passport or a photocard driving licence.
• A recent utility bill, council tax bill or bank statement dated within the last three months, showing your current address.
• If you have lived at your address for less than three years, an address history covering the full period.
• Your national insurance number.
• Proof of right to reside in the UK if you are not a British or Irish citizen, including visa details and expiry date.

A photocard driving licence used for identity usually cannot also serve as proof of address, so plan for two separate documents.

If you are employed

• Last three months of payslips, or the last three payslips if you are paid weekly or four-weekly, in which case lenders often want more.
• Latest P60.
• Last three months of personal bank statements showing salary credits going in.
• Employment contract or a letter from your employer if you have recently started, changed role or are still in a probation period.
• Evidence of bonus, commission or overtime if you want it counted. Usually two years of payslips or P60s, or an employer letter confirming the pattern.

If you have changed jobs in the last six months, say so at the fact find. Lenders differ on how they treat probation periods, and it changes which lender you should be applying to.

Sole traders and partnerships:

• SA302 tax calculations for the last two or, more often, three tax years, downloadable from your HMRC online account.
• Matching tax year overviews for the same years. Lenders want both, because the overview confirms the tax was actually declared.
• Last three months of business and personal bank statements.
• Accountant's details, since some lenders write to them directly.

Limited company directors:

• Two or three years of finalised company accounts.
• Personal tax calculations and tax year overviews for the same years, showing salary and dividends.
• Confirmation of your shareholding percentage.
• Some lenders will consider retained profit within the company rather than only what you have drawn, which can materially increase what you can borrow. This is one of the clearest cases where lender choice changes the outcome.

If your latest year is much stronger than the previous one, that is worth flagging, because some lenders use the latest year while others average two or three.

• Your current contract, showing the day rate, the start and end dates, and the parties.
• Evidence of your contracting history, often twelve months in the same line of work.
• Your CV in some cases.
• Bank statements showing the income arriving.
• If you contract through a limited company, expect the limited company document list too, unless the lender assesses you on the day rate.

Day rate assessment can be considerably more generous than accounts-based assessment for a contractor, which is why getting the right lender matters here.

Lenders are required to establish the source of your deposit. Vague answers cause delays.

• Savings: three to six months of statements for the account holding the money, showing it building or sitting there.
• Sale of a previous property: the completion statement from your conveyancer.
• Inheritance: a letter from the executor or solicitor, plus the bank statement showing it arriving.
• Bonus or a large one-off payment: the payslip and the matching credit on your statement.
• Cryptocurrency or share sales: the exchange or broker statement plus the transfer into your UK account, and expect additional questions.
• Money held overseas: proof of source and evidence of transfer. Some lenders decline this entirely.

Any unexplained credit over a few hundred pounds on your statements may be queried. If your mother repaid you 2,000 pounds she borrowed, be ready to say so.

If any part of the deposit is a gift, the lender will want a signed gifted deposit letter from the donor confirming that the money is a gift and not a loan, that the donor retains no interest in the property, and that it is not repayable.

You will also usually need the donor's identity documents and evidence of where their money came from. Your conveyancer will run their own anti money laundering checks on the same funds, which is a separate exercise from the lender's.

Lenders differ on who may gift. Parents are accepted almost everywhere. Grandparents and siblings are widely accepted. Friends, employers and non-resident relatives are accepted much less often. Ask before you rely on it.

In addition to the standard set:

• Evidence of the expected rental income, usually a letter or valuation from a letting agent, though the lender's own valuer will also give a rental figure.
• Details of your existing portfolio if you own other rental property, typically a schedule listing addresses, values, outstanding mortgages, monthly payments and rents.
• Personal income evidence, because many buy to let lenders set a minimum income requirement.
• For a limited company purchase, the company's incorporation documents, the SIC code, details of all directors and shareholders, and personal guarantees from the directors.

• The reservation form and the developer's plot details.
• The anticipated build completion date and the long stop date.
• Details of any incentives from the developer, such as a deposit contribution, stamp duty paid, or white goods included. These must be disclosed, and lenders limit how much incentive they will accept.
• A new build warranty, for example NHBC or an equivalent.

Offer expiry is the recurring problem on new build. If the build will not complete within the offer validity period, your broker needs to plan for an extension or a re-offer from the start.

• Gather everything before you make an offer on a property, not after.
• Scan documents in full. A payslip photographed with the corner cut off will be rejected.
• Make sure names and addresses match across documents. A missing middle name or an old address triggers manual checks.
• Do not open new credit, change jobs or move money around unusually in the three months before applying.
• Keep your bank statements tidy and be ready to explain anything unusual on them.
• Register on the electoral roll at your current address if you are not already.
• Tell your adviser about anything awkward on day one rather than letting the underwriter find it.

Requirements differ between lenders and change over time, so your adviser should give you a list tailored to the lender they are recommending.
