Remortgage documents checklist (UK)

Remortgaging or moving onto a new product with the same lender is as much a paperwork exercise as a rate-shopping exercise. Lenders and conveyancers need evidence of who you are, what you earn, what you already owe, and what sits against the property. Gaps or mismatched dates are a common reason applications stall in the final weeks before a fixed rate ends.

This page is a practical checklist of documents commonly requested for a UK remortgage or a product transfer (sometimes called a retention). It describes process only. It is not personalised advice, not a promise that every lender asks for the same pack, and not a recommendation of any product. Exact lists come from your lender, broker or solicitor.

If your fix is already in its last eight weeks, pair this list with the week-by-week plan in Fixed rate ending — what to do next. When you receive a Key Facts Illustration (or European Standardised Information Sheet), see How to read an illustration for what the rate, fee and ERC lines usually mean.

Gather early — before rate-hunting

Collecting documents first makes the rest of the process smoother. You can answer underwriting questions quickly, instruct a conveyancer without delay, and put real figures into a true-cost comparison instead of guesses. Start with papers you already hold at home or in online banking, then request anything missing (redemption figures, tax calculations, lease packs) while you still have calendar room.

Product transfers often need a lighter pack than a full remortgage to a new lender. Full remortgages usually involve identity checks, affordability evidence, a valuation and legal work to redeem the old charge and register the new one. Treat the sections below as a master list, then tick only what your path requires.

Current mortgage and deal paperwork

These items sit at the centre of timing and cost, whether you stay or switch:

• Latest mortgage statement showing outstanding balance, account number, property address and payment history
• Original mortgage offer, Key Facts Illustration or equivalent for the current deal — including the deal end date and any early repayment charge (ERC) wording
• Written note of when the ERC (if any) ends, and how it is calculated (percentage of balance, sliding scale, or fixed sum)
• Provisional or formal redemption statement method from the current lender (how daily interest is counted if completion slips)
• Any exit, discharge, deeds or admin fees that apply on full redemption
• Product-transfer or retention quotes and fee schedules from the current lender, if offered
• Reversion / standard variable rate (SVR) wording — or a written figure for the rate that would apply after the fix if no new product is in place

Fees and ERCs often decide the arithmetic before headline rates do. Our Remortgage true cost calculator is built for those lines once you have them in writing.

Identity and proof of address

Lenders must verify identity and address under anti-money-laundering rules. Typical requests include:

• Photo ID — current passport and/or photocard driving licence (full or provisional, as the lender accepts)
• Proof of current address dated within the lender’s window (often three months) — for example a utility bill (not usually a mobile phone bill), council tax bill, or bank / building society statement
• For joint applications, ID and address evidence for each applicant
• Any change-of-name evidence (marriage certificate, deed poll) if names differ across documents

Scans or clear photos are often accepted for upload, but some lenders still ask for certified copies via a solicitor or broker. Follow the channel your lender specifies.

Income evidence — employed

For PAYE employment, lenders commonly ask for recent income evidence that matches bank credits:

• Latest payslips — often the most recent three consecutive months
• Most recent P60 for the last full tax year
• Personal bank statements covering the same period, showing salary credits and regular outgoings
• Employment contract or starter paperwork if you changed jobs recently or are on a fixed-term contract
• Evidence of regular overtime, bonus or commission if those amounts form part of the income the lender will use

If income is variable, expect more months of payslips. Keep filenames and dates tidy so underwriters can match each slip to a bank credit without chasing you.

Income evidence — self-employed and company directors

Self-employed applicants and limited-company directors usually face a longer evidence trail. Common items include:

• HMRC tax calculations (often called SA302s) for the last two or three tax years
• Matching HMRC tax year overviews for the same periods
• Certified accounts or an accountant’s certificate covering the trading period the lender requires
• Business bank statements where the lender asks for trading evidence
• Personal bank statements showing drawings, salary or dividends as relevant to how income is assessed

Download tax documents from your HMRC online account early — postal copies take longer. Criteria differ by lender; some weight average profit, others take a different slice of director remuneration. Your illustration and underwriting notes state what was used.

Outgoings, credit and other commitments

Affordability checks look at committed spending as well as income. Have details ready for:

• Loans, hire purchase and car finance — balances, monthly payments and end dates
• Credit cards and store cards — limits and typical balances
• Childcare costs, maintenance or CSA / CMS arrangements
• Student loan repayments if they appear on payslips or bank statements
• Other mortgages or secured loans, including buy-to-let if you hold them
• Any guarantor, shared ownership or help-to-buy style arrangements still in force on the property

MoneyHelper notes that lenders look closely at whether repayments remain affordable if rates rise or household income changes. Clear statements reduce follow-up questions.

Property, title and legal pack

On a remortgage to a new lender, conveyancers usually need property papers. Common requests include:

• Property address and, if known, title number
• Freehold or leasehold status — for leasehold, the lease, service-charge accounts and any buildings insurance details the solicitor requests
• Buildings insurance schedule (some lenders require cover to be confirmed before completion)
• Details of alterations, extensions or loft conversions, plus planning or building-control paperwork if asked
• Shared ownership, freehold management or estate-rentcharge documents where they apply
• Contact details for your chosen conveyancer if the product does not include a lender panel solicitor

Product transfers often skip a full legal remortgage pack, which is one reason they can complete faster when time is short. That does not remove the need to read the new product terms, fees and ERC schedule.

What a product transfer often needs instead

A product transfer keeps the same lender and usually the same account. Typical paperwork is lighter:

• Identity confirmation if the lender’s records are out of date
• The retention or product-transfer illustration and fee schedule
• Confirmation of the start date relative to the current deal end date (to limit days on SVR)
• Any declaration the lender requires about occupancy, insurance or further borrowing

Some transfers do not repeat a full affordability assessment when you are not borrowing more and remain within the lender’s rules — but that is lender-specific. Always read the transfer terms you are offered rather than assuming the pack is empty.

Illustrations, offers and Agreement in Principle

Alongside identity and income packs, keep the decision documents organised:

• Agreement in Principle / Decision in Principle reference if you explored a new lender
• Key Facts Illustration or ESIS for each product you are seriously comparing — rate, APRC, fees, cashback and ERC lines
• Formal mortgage offer once issued, plus its validity window
• Valuation type and result when a new lender instructs one (desktop, drive-by or full inspection)

Suggested order of gathering

1. Current mortgage offer, statement, ERC end date and any retention quote — so timing and cost are visible.
2. Photo ID and recent proof of address for every applicant.
3. Income pack (payslips and P60, or SA302s / tax year overviews and accounts) plus matching bank statements.
4. Credit commitments and regular outgoings listed with monthly amounts.
5. Property and lease documents if a new-lender remortgage is on the table.
6. Illustrations and, later, the formal offer — filed with the redemption method for the completion date you are aiming at.

Working in that order supports the calendar in Fixed rate ending and the step sequence in How remortgaging works in the UK.
