Everything you need to know about how to remortgage uk in the UK.
Remortgaging means replacing your existing mortgage with a new one, either with the same lender (a product transfer) or a different lender. The process typically takes 4–8 weeks from application to completion, though straightforward cases can complete faster and complex situations may take longer.
The process involves several stages: research and comparison, application, valuation, legal work, and completion. Understanding each step helps you prepare the right documents, set realistic timelines, and avoid common delays.
Start by checking your current mortgage deal: the interest rate, remaining term, monthly payment, and crucially, when your current fixed or tracker rate ends. Also check whether any early repayment charges (ERCs) apply. These details are on your annual mortgage statement or available by calling your lender.
Gather the documents you will need for the application. Most lenders require your last three months of payslips, your latest P60 or tax calculation, three months of bank statements, proof of address, photo ID, and details of your current mortgage including the outstanding balance and account number.
Compare remortgage deals from across the market, factoring in the interest rate, arrangement fees, valuation fees, and legal costs. Use a mortgage broker or comparison tool to find the best overall deal for your situation. Remember to compare the total cost over the deal period, not just the headline rate.
Most lenders allow you to apply for a remortgage 3–6 months before your current deal ends, locking in the new rate. If rates fall before completion, some lenders will let you switch to the lower rate. If rates rise, your locked rate is protected. This gives you the best of both worlds.
💡 A mortgage broker handles the comparison and application process for you, including submitting paperwork and liaising with the lender. Most brokers do not charge a fee for remortgage advice (they are paid by the lender), making their service effectively free to you.
The new lender will arrange a valuation of your property to confirm its worth and ensure the LTV is within acceptable limits. This may be a physical valuation (a surveyor visits the property) or an automated desktop valuation (the lender uses data and algorithms to estimate the value without a visit).
Desktop valuations are increasingly common for remortgages, especially at lower LTVs, and speed up the process significantly. If a physical valuation is required, the surveyor's visit typically takes 15–30 minutes. Many remortgage deals include the valuation at no cost. If the valuation comes in lower than expected, it could affect the LTV and the rate offered, or in some cases, lead to the application being declined.
Even though you are not buying or selling a property, remortgaging requires legal work to transfer the mortgage charge from your old lender to the new one. A solicitor or conveyancer handles this process, which includes identity checks, reviewing the title deeds, conducting necessary searches, and registering the new mortgage with the Land Registry.
Many remortgage deals include free conveyancing provided by a panel solicitor appointed by the lender. If you prefer to use your own solicitor, you will need to pay their fees (typically £300–£1,000). The legal work usually takes 2–4 weeks and is often the part of the process that takes the longest.
Once the valuation and legal checks are satisfactory, the new lender issues a formal mortgage offer. This document confirms the loan amount, interest rate, term, monthly payment, and all conditions. Review it carefully and raise any questions with your broker or solicitor before proceeding.
On completion day, the new lender sends the mortgage funds to your solicitor, who uses them to repay your old mortgage. Any additional funds (if you are borrowing more) are transferred to your bank account. Your first payment to the new lender is typically due one month after completion. The entire switch happens in the background with no disruption to your daily life.
⚠️ Ensure there is no gap between your old deal ending and your new one starting. If your old fixed rate ends on 1 March and your new mortgage does not complete until 15 March, you will spend two weeks on the SVR, costing you unnecessary money. Planning ahead and starting the process early avoids this common pitfall.
The most frequent causes of delay are incomplete paperwork (missing payslips, unsigned documents), valuation issues (the property valued lower than expected, or access problems for a physical valuation), and legal complications (title issues, leasehold queries, or slow communication with your existing lender).
To minimise delays: have all your documents ready before applying, respond promptly to any requests from the lender or solicitor, and ensure the surveyor can access your property for valuation. If you are self-employed, having clean and up-to-date accounts makes a significant difference to processing times.
