Remortgaging means replacing your existing mortgage with a new deal, usually because your current fixed or discounted rate is ending, you want a more competitive rate, or you need different features. For UK homeowners, the mortgage switch process is easiest to manage as a sequence: review your existing loan, compare options, apply, complete valuation and legal work, receive the mortgage offer, then complete the switch.
MoneyHelper suggests shopping around up to six months before your deal ends, giving you time to compare options carefully and avoid last-minute decisions.
Step 1: Check your current mortgage
Confirm your outstanding balance, current rate, monthly payment, remaining term and the exact date your deal ends. Check whether an early repayment charge applies and whether your lender charges an exit or administration fee. A lower rate elsewhere is not automatically cheaper if leaving early triggers a substantial charge.
Step 2: Decide what you need from the new deal
You may simply want to replace an expiring fixed rate, but remortgaging can also change the term, repayment features or borrowing amount. Additional borrowing can make the application more involved because the lender may need to assess the extra debt and affordability.
Compare a full remortgage with a product transfer from your current lender. A transfer can be simpler, while a new lender may offer wider choice. Compare overall cost and features, not just the advertised rate.
Step 3: Estimate your loan-to-value
Your loan-to-value, or LTV, is your mortgage balance as a percentage of the property’s value. If you owe £180,000 and your home is worth £240,000, your LTV is 75%. Lenders often price products in LTV bands.
Treat your own valuation as a starting point. The lender decides what property value it accepts. If its valuation is lower than expected, your LTV may move into another pricing band.
Step 4: Compare the full cost, not just the rate
Compare product fees, valuation charges, legal costs, cashback, incentives and charges for leaving your existing lender. MoneyHelper notes that changing a mortgage can cost £1,000 or more in some cases, although some deals include valuation or legal services.
Compare costs over the period you expect to keep the deal. On a smaller balance, a slightly higher rate with no large fee can cost less overall than a lower rate with a substantial fee. Review remortgage fees and costs before committing.
Step 5: Prepare your documents and finances
Get your paperwork ready before applying. Depending on the lender, you may need proof of identity and address, bank statements, payslips or other income evidence, plus information about loans, credit cards and regular spending. Self-employed applicants may need accounts, tax calculations or other evidence of earnings.
Check your credit reports for errors and make sure application figures match your documents. Avoid unnecessary new borrowing during assessment. A remortgage documents checklist can prevent delays.
Step 6: Submit the mortgage application
Once you choose a suitable product, you or your broker submit the full application. The lender reviews it against criteria that can include income, expenditure, credit history, property type, LTV and any extra borrowing. FCA rules provide flexibility for certain straightforward remortgage cases, but each lender still applies its own policies.
Step 7: The lender values your property
The lender must be satisfied that the property provides adequate security. Depending on the lender, property and available data, the valuation may be automated, remote or involve a physical inspection.
A mortgage valuation is mainly for the lender; it is not the same as a detailed condition survey. If you want a fuller inspection for defects or maintenance concerns, that is a separate service. Understanding how mortgage valuations work can help you prepare for this stage.
Step 8: Complete the legal work
When moving to a different lender, legal work is normally needed to replace the old lender’s security with the new lender’s charge. A solicitor or conveyancer may check title information, obtain a redemption statement, handle the new mortgage deed, arrange repayment of the old loan and deal with registration after completion. Exact procedures vary by lender and across the UK.
Some products include a legal service; others offer cashback towards costs. If you use your own conveyancer, check that the firm is acceptable to the new lender before instructing it.
Step 9: Receive and check the mortgage offer
When underwriting and valuation are complete, the lender can issue a formal mortgage offer. Check the loan amount, interest rate, monthly payment, term, fees, early repayment conditions and any special requirements.
The offer is a major milestone, but completion still depends on the legal work. Avoid significant financial changes that could affect the mortgage and disclose material changes when required.
Step 10: Complete the remortgage
On completion day, the new lender sends funds to the solicitor or conveyancer. The old mortgage is repaid using the redemption figure, agreed fees are settled and any approved additional borrowing is transferred as appropriate. The legal representative then deals with registration of the new lender’s charge.
Do not cancel your old mortgage direct debit too early. Wait until the former lender confirms repayment, then check the date and amount of your first payment to the new lender.
A practical remortgage timeline
Suppose your fixed rate ends on 30 September. You could start comparing deals in April, narrow your options in May and submit an application in June. That leaves the summer for underwriting, valuation and legal work, with completion planned after the old deal’s early repayment charge period ends.
The remortgage steps can overlap, and document checks, valuation and conveyancing may move at different speeds. Starting early gives you room to answer queries without rushing into a poor decision.
Frequently asked questions
How long does the remortgage process take?
There is no guaranteed timescale. Straightforward cases may progress quickly, while underwriting questions, valuation issues, legal work, leasehold information or unusual title matters can cause delays. Beginning several months before your existing deal expires gives you more flexibility.
Do I need a solicitor to remortgage?
If you move to a new lender, legal work is normally required. Your lender may provide a conveyancer or allow you to use a firm from its approved panel. A simple product transfer may not need the same conveyancing process.
Will the lender check affordability?
Often, yes. The exact assessment depends on the circumstances and lender. Lenders may review income, spending, debts and other commitments, particularly if you are borrowing more. FCA rules also allow modified assessment approaches for some eligible remortgage cases.
Can I remortgage before my fixed deal ends?
You can usually apply before the current deal finishes, and many products can be arranged months in advance. Completing too early can trigger an early repayment charge, so check dates and total costs before setting completion.
Final thoughts
The remortgage process step by step becomes easier when you separate the financial decision from the administration. Understand your current mortgage and exit costs, compare the total cost of suitable deals, prepare your evidence, apply, complete valuation and legal stages, check the offer and coordinate completion. Starting early gives you time to make a deliberate choice rather than accepting whatever is available when your current rate expires.
