Why Preparation Matters

The most common cause of remortgage delays is incomplete or slow documentation from the applicant. Lenders receive applications across a range of complexity levels, and well-prepared applications with all evidence in place move through underwriting faster and with fewer queries.

Before you apply — whether directly to a lender or through a broker — gather everything on this checklist. Most documents can be obtained digitally and submitted via upload to an online application portal.

Section 1: Your Existing Mortgage Details

You will need to provide the new lender with details of the mortgage you are replacing. Gather:

[ ] **Lender name and account number** — on your mortgage statement or annual summary
[ ] **Outstanding balance** — most recent statement or log into your lender's portal
[ ] **Current monthly payment** — from your bank statement or direct debit schedule
[ ] **Remaining term** — how many years/months are left
[ ] **Current interest rate** — the rate you are currently paying
[ ] **Deal expiry date** — when your current fixed rate or tracker ends
[ ] **Early Repayment Charge details** — from your original mortgage offer document or lender portal

Section 2: Property Details

[ ] **Registered address** — ensure it matches your Land Registry title exactly
[ ] **Tenure** — freehold or leasehold (if leasehold, note remaining years on the lease)
[ ] **Estimated current value** — many lenders conduct their own valuation, but your estimate is needed for the application; research recent comparable sales locally
[ ] **Any charges or restrictions on title** — if you are aware of any charges beyond the existing mortgage (second charge loans, charging orders), flag these to the broker/lender
[ ] **Leasehold details** (if applicable):
[ ] Annual ground rent (and any escalation clause)
[ ] Annual service charge
[ ] Name and contact details of the freeholder or managing agent
[ ] Whether the lease has been reviewed or has any unusual clauses

*Note: Many lenders will not remortgage leasehold properties with fewer than 70–85 years remaining on the lease after the mortgage term ends. If your lease is short, seek advice early.*

Section 3: Identity and Address Verification

All lenders must verify your identity and address under anti-money laundering regulations.

[ ] **Photo ID** — passport or driving licence (in date)
[ ] **Proof of address** — utility bill, council tax bill, or bank statement dated within three months, showing your current address
[ ] **Electoral roll registration** — confirm you are registered at your current address (check at gov.uk)

Section 4: Income Evidence — Employed Applicants

[ ] **Last three months' payslips** (paper or PDF from your employer's portal)
[ ] **Latest P60** (issued by employer after each April 5 tax year-end)
[ ] **Latest three to six months' bank statements** (the account into which your salary is paid)
[ ] **Employment contract** (if requested — particularly for recent job changes)
[ ] If you receive **bonus income**: P60 for last two to three years and/or employer confirmation of bonus history

Section 5: Income Evidence — Self-Employed / Limited Company Directors

[ ] **Two years' SA302 tax calculations** — download from HMRC Online Account (Self Assessment section)
[ ] **Two years' Tax Year Overviews** — also from HMRC Online Account (confirms tax paid/owed)
[ ] **Two years of company accounts** (limited company directors) — prepared and signed by a qualified accountant
[ ] **Three to six months' business bank statements**
[ ] **Three to six months' personal bank statements**
[ ] **Accountant's reference letter** (some lenders require this to confirm income figures)

Section 6: Outgoings and Commitments

Lenders will assess your affordability by examining your committed outgoings. Be prepared to declare:

[ ] **Existing loan repayments** (personal loans, car finance — monthly amounts and remaining terms)
[ ] **Credit card balances** (and minimum monthly payments)
[ ] **Student loan** (lenders see this on payslips but you should declare it)
[ ] **Childcare costs** (monthly amount and expected duration)
[ ] **Any maintenance or child support payments**
[ ] **Ground rent and service charges** (if applicable on your current home)

Bank statements are reviewed to verify declared outgoings — undeclared commitments visible on statements may cause queries or delays.

Section 7: Credit File

Before applying, check your own credit report:

[ ] **Experian** — checkmyfile.com gives all three agencies; Experian also has a direct free report
[ ] **Equifax** — via checkmyfile or direct
[ ] **TransUnion** — via checkmyfile or Credit Karma

Resolve any issues before applying:

[ ] Confirm electoral roll registration
[ ] Dispute and correct any errors
[ ] Note any adverse markers (missed payments, defaults, CCJs) and their dates — you will need to declare these

Section 8: Remortgage-Specific Decisions

Before you submit your application, know your preferences:

[ ] **New loan amount** — are you keeping the same balance or increasing/decreasing it?
[ ] **New term** — are you extending or maintaining the existing remaining term?
[ ] **Product type** — two-year fix, five-year fix, tracker, or other?
[ ] **Overpayment preference** — do you want to maintain the payment level (reducing term) or reduce the monthly payment?
[ ] **Portability** — if you may move in the next few years, consider whether a portable product has value
