Your current deal may be ending soon, your monthly payment may have risen, or your household plans may simply have changed. Knowing how to remortgage puts you in a stronger position before your lender’s standard variable rate takes over. The right move is not always the lowest headline rate – it is the mortgage that suits your property, income, plans and budget.
A remortgage means replacing your existing mortgage with a new one, either with your current lender or a different provider. You might keep the borrowing at the same level, borrow more for an agreed purpose, or change the mortgage term. It can be straightforward, but the best time to start is usually well before your current deal ends.
When should you start a remortgage?
Many lenders allow a new mortgage application to be arranged up to six months before completion. Starting early gives you time to understand your options, gather paperwork and deal with any lender queries without rushing. It may also help you secure a product before your existing fixed rate ends.
Check the date your current deal finishes, not just the date you first took out the mortgage. Your mortgage offer or annual statement should show this, along with any early repayment charge. An early repayment charge is a fee your lender may apply if you leave a fixed or discounted deal before it ends. In some cases, paying it can still make financial sense, but it needs to be weighed carefully against any potential saving.
If you do nothing when a deal expires, many mortgages move onto the lender’s standard variable rate. This is often higher than a fixed or tracker product, although rates can change and there is no single answer that suits every borrower.
How to remortgage: a practical step-by-step process
1. Review your current mortgage
Start with the facts. Confirm your outstanding balance, interest rate, monthly payment, remaining term and deal end date. You should also find out whether there are exit fees, early repayment charges or product fees to consider.
It is worth looking at the full cost, not only the rate. A mortgage with a lower rate and a large arrangement fee may not be cheaper over the period you expect to keep it. Equally, a fee-free option can be useful for borrowers with a smaller balance or those who may move again in the near future.
2. Work out what has changed
Lenders will assess your current circumstances, even if you have paid your mortgage without difficulty for years. Think about changes to your income, employment, household spending, credit commitments and family plans. If your income has become more complex, for example through self-employment, overtime, commission or a combination of salaries and dividends, the way a lender assesses it can vary.
Also consider your property’s likely value. This affects your loan-to-value, often shortened to LTV. If you owe £180,000 on a home worth £300,000, your LTV is 60%. Generally, a lower LTV can open up more competitive mortgage pricing, although lender criteria and affordability still matter.
3. Decide what you need from the new deal
A remortgage is a chance to make a deliberate choice rather than simply accepting the next rate offered. You may want payment certainty through a fixed-rate mortgage, or you may prefer the flexibility of a tracker. You might choose to keep your term the same, reduce it to repay the loan sooner, or extend it to make payments more manageable.
Be realistic about the trade-offs. Extending the term can reduce the monthly payment, but you are likely to pay more interest overall if nothing else changes. Shortening the term may save interest, but affordability must remain comfortable enough to cope with everyday life and unexpected costs.
Some homeowners also consider borrowing additional funds for home improvements or to consolidate existing debts. This needs particular care. Moving short-term debts onto a mortgage can lower monthly outgoings, but it may increase the total amount repaid because the borrowing lasts longer. Your home may be repossessed if you do not keep up repayments on a mortgage or other loan secured on it.
4. Check your credit position and documents
Before applying, check that your personal details are accurate on your credit file and that you are registered on the electoral roll at your current address. Missed payments, high credit-card balances and recent applications for credit can affect the options available, but they do not automatically mean a remortgage is impossible. The right lender depends on the full picture.
You will normally need recent proof of income, bank statements, identification and details of your existing mortgage. Employed applicants may provide payslips and P60s. Self-employed applicants may need accounts, tax calculations or other evidence, depending on the lender. Providing clear documents promptly can prevent avoidable delays.
5. Compare suitable lenders and products
A product transfer with your existing lender can sometimes be quick and may not require the same level of underwriting as moving to a new lender. However, it is still sensible to understand how it compares with other suitable options. Staying put may be convenient, but it is not automatically the best value or the best fit for your plans.
A full remortgage to a new lender may involve a valuation, legal work and a more detailed affordability assessment. Some products include a free valuation or legal service, while others charge fees. These details matter, particularly where you have limited equity, a changing income, or a deadline linked to your current deal ending.
An adviser can assess products across lenders and explain the practical differences in plain English. At CoG Financial, that means looking beyond a rate table and taking time to understand what you want the remortgage to achieve.
6. Submit the application and respond quickly
Once you have chosen a suitable route, the lender reviews your application, income, expenditure, credit history and property. The valuation may be desktop-based or may require an inspection. A solicitor or conveyancer will usually handle the legal work when you switch lender, including repaying the old mortgage at completion.
Keep an eye on messages and respond to requests promptly. A lender may ask for an updated bank statement, clarification of a payment or further income evidence. It is normal for questions to arise, and a responsive adviser can keep you informed about what is happening and what is needed next.
7. Check completion is timed correctly
Before completion, confirm that the new mortgage will repay the old one and that your new monthly payment date is clear. If you are changing lender, there may be a final payment to the old lender and then a new direct debit to set up. Do not cancel your existing direct debit until you know the previous mortgage has been redeemed.
If your current deal has a precise end date, timing is especially important. Completing too early could trigger an early repayment charge. Completing too late could mean spending time on a higher variable rate. Your adviser and solicitor can help coordinate the process, but it is still useful to keep your own record of key dates.
Questions to ask before you commit
Ask how long the new rate lasts, what the payment could become after the deal period, and whether fees are paid upfront or added to the loan. If fees are added to the mortgage, you will usually pay interest on them too. You should also ask whether the product is portable if you might move home during the fixed period, and what overpayment allowance is available.
Protection deserves a place in the conversation as well. A mortgage is often a household’s largest commitment. Life insurance, critical illness cover or income protection may help provide financial support if illness, injury or death affects the ability to meet payments. The right cover depends on your family, employment benefits, savings and existing policies.
Avoid treating a remortgage as a last-minute task
The most useful next step is often simply to begin early, with accurate information and a clear idea of what matters most to you. A remortgage should reduce uncertainty, not create more of it. With a named adviser to explain the options and keep the application moving, you can make a considered decision without trying to navigate every lender requirement alone.
