A mortgage deal ending can feel distant until the reminder lands in your inbox and your monthly payment is about to change. Knowing when to remortgage before deal ends gives you time to compare your options properly, protect yourself from a move on to your lender’s standard variable rate and make a decision that works for your household budget.
For many homeowners, the right time to begin is earlier than expected. A new mortgage does not normally need to start immediately, but the application, valuation and legal work can all take time. Starting the conversation early means you are less likely to make a rushed choice just because the end date is approaching.
When to remortgage before your deal ends
In most cases, it is sensible to start reviewing your mortgage around six months before your current fixed or tracker deal finishes. Many lenders allow you to secure a new rate several months in advance, although each lender has its own rules and the offer may only be valid for a set period.
This does not necessarily mean you should complete the remortgage six months early. If your existing deal has an early repayment charge, completing before the deal end date could be expensive. Instead, the aim is usually to arrange the new mortgage in advance and set its completion date for when your current deal ends, or shortly afterwards.
A mortgage adviser can check the dates, product rules and charges with you. This is particularly valuable if you are balancing a fixed-rate expiry, a change in income, a planned move or a need to raise funds. The cheapest-looking rate is not automatically the most suitable option once fees, term length and your wider plans are considered.
Why acting early can protect your budget
When an introductory deal ends, your mortgage commonly switches to the lender’s standard variable rate, often called the SVR. This rate can be significantly higher than the rate you have been paying, and it can change at the lender’s discretion. Even a modest rate increase may add a noticeable amount to your monthly payment.
Applying early gives you breathing room. Your adviser can assess what you can borrow, search suitable products and identify whether a new deal with your current lender or a different lender is likely to offer better value. If a lender’s underwriting takes longer than expected, you are also less likely to be left without a plan at the point your current product ends.
There is another benefit: mortgage rates can move while you are deciding. Securing a product can provide certainty for a limited period, subject to the lender’s conditions. If rates later improve before you complete, it may be possible to review alternatives, but that depends on the lender, timings and your circumstances. It is not a reason to delay taking advice, but it is a reason to give yourself options.
Check your early repayment charge first
An early repayment charge, or ERC, is one of the main reasons not to remortgage too soon. It is a charge your existing lender may apply if you repay all or part of your mortgage before a specified date. It is often a percentage of the outstanding balance, so it can run into thousands of pounds.
Your mortgage offer and annual statement should show when any ERC applies, but check the detail rather than relying on memory. Some deals have a charge that falls over time; others allow a certain level of overpayment without penalty. Your lender can confirm the exact figure and the date the charge ends.
Occasionally, paying an ERC may still be worth considering, particularly where the saving from a new rate is substantial or your circumstances have changed. That calculation needs care. It should compare the charge, arrangement fees, valuation or legal costs where applicable, the new monthly payment and the total cost over the period you expect to keep the mortgage. A lower payment in the first month does not always mean lower overall cost.
Start with the right questions
Before an application is submitted, it helps to be clear about what has changed since you last arranged your mortgage. Lenders will look at affordability now, not simply at whether you have maintained your existing payments.
Think about your income, regular commitments, outstanding credit, childcare costs and future plans. A new job, reduced overtime, self-employed income, a recently cleared loan or an expected addition to the family can all affect the options available. If you are considering debt consolidation, extending the mortgage term or borrowing extra for home improvements, be open about it from the outset. These choices can reduce monthly outgoings but may increase the total amount repaid over time, especially if debts are repaid over a longer period.
It is also worth checking your credit report well before you apply. Correcting an error, registering on the electoral roll or allowing time after a recent credit application can sometimes make the process smoother. Do not take out new credit unnecessarily in the run-up to an application unless it is needed.
Product transfer or remortgage?
You may receive a product-transfer offer from your current lender before your deal ends. This is a new rate with the same lender, usually without moving the mortgage elsewhere. It can be quick and may involve less paperwork, making it a useful option for some borrowers.
However, a product transfer is not always the best value or the best fit. A remortgage to a new lender could offer a more competitive rate, different features or the ability to borrow more, although it will normally involve a full affordability assessment and may take longer. Conversely, staying with your existing lender can be sensible where your circumstances have become more complicated and a new application could be difficult.
The right route depends on the whole picture: the rate, fees, repayment method, mortgage term, flexibility for overpayments and your plans for the property. This is where personal advice can save time and avoid a decision based solely on a headline rate.
Allow time for the application process
A straightforward remortgage may complete in a matter of weeks, but there is no guaranteed timetable. The lender may need proof of income, bank statements, identification and details of your existing mortgage. For self-employed applicants, accounts, tax calculations and tax year overviews may be required. The property valuation can also influence the lender’s final decision, particularly if its value has changed since you bought it.
Using electronic document sharing can remove some of the usual paperwork delays, but prompt responses still matter. Keep payslips, bank statements and identification to hand, and tell your adviser early if anything may need explaining, such as a gifted payment, commission income or a recent change in employment.
If your current deal ends before the new mortgage completes, you may spend a short period on the SVR. That is not ideal, but it does not mean the remortgage has failed. Your adviser can help set expectations and monitor progress, while ensuring you understand the cost of any gap.
Avoid choosing on rate alone
A two-year fixed rate can suit someone who expects to move, sell or make major changes in the near future. A five-year fixed rate may appeal if predictable payments matter more and you are comfortable with the longer commitment. Neither is automatically better.
Look closely at product fees. A deal with a very low interest rate may carry a sizeable fee, which can make it less competitive for a smaller mortgage balance or a borrower planning to remortgage again soon. Consider whether the fee is paid upfront or added to the loan. Adding it to the mortgage can help cash flow, but interest may be charged on it.
Flexibility matters too. Check overpayment allowances, portability if you may move home, and any ERC structure. A mortgage should support the life you expect to lead, not tie you into a deal that becomes costly if plans change.
A calmer way to approach your next deal
Six months before your deal end date, gather your mortgage details and book a conversation. At around three to four months out, you should ideally have a clear view of the products available, the likely costs and any actions needed to complete on time. If the deadline is closer than that, it is still worth seeking advice promptly rather than accepting the first offer that appears.
At CoG Financial, an adviser can look beyond a rate table, explain the trade-offs in plain English and keep you updated throughout the process. The most useful next step is simple: check your deal end date now, then give yourself enough time to make a confident choice rather than an urgent one.
