If your fixed-rate mortgage is ending, prepare for the payment your own lender quotes rather than relying on a market average. Check the expiry date, rebuild your household budget and ask about support before a payment becomes unaffordable. This guide covers UK mortgages; Canadian renewal arrangements follow different rules.
Anúncios
- An expiring fixed deal can move to a different rate without a replacement arrangement.
- A workable budget includes other household bills, not just the mortgage instalment.
- A smaller monthly payment can mean a larger overall borrowing cost.
- Discussing support is different from agreeing a change that affects your credit file.
What happens when your fixed mortgage deal ends?
The end of a fixed deal is not normally the date the entire mortgage must be repaid. It is the end of the period during which the agreed interest rate stays fixed. The remaining loan still needs a payment arrangement.
According to Financial Conduct Authority guidance reviewed in October 2026, borrowers who do not arrange another deal move to their lender’s reversion rate. That is often a standard variable rate, although another type of rate can apply. The FCA says this rate will normally exceed the introductory rate.
Read your mortgage statement and original offer together. Find the fixed-rate expiry date, the remaining balance and the remaining repayment term. Ask the lender to confirm the rate and payment that would apply afterwards, including when the first changed payment would leave your account.
A headline about average mortgage rates cannot supply those answers. Your payment depends on your own loan and the terms available to you. Likewise, understanding the limits of interest rate forecasts helps separate a possible market movement from an actual household commitment.
How can you check whether the new payment is affordable?
Start with reliable take-home income and spending shown on recent statements. Replace the current mortgage payment with the lender’s proposed payment, keeping the rest of the budget realistic. A plan that works only by ignoring routine expenses is not evidence that the mortgage is affordable.
Include costs that arrive less regularly, such as home maintenance, insurance renewals and vehicle repairs. Record whether savings are available for emergencies or already set aside for a known bill. Using savings temporarily and funding a lasting payment increase are different decisions.
Build a practical information checklist
- Record regular income separately from overtime, bonuses or other uncertain receipts.
- List essential housing, energy, food, transport and caring costs.
- Keep other debt repayments visible instead of treating them as spare spending.
- Note upcoming changes to work, childcare or retirement income.
- Identify a continuing shortfall even after realistic spending adjustments.
Citizens Advice’s England guidance, reviewed in October 2026, highlights checking income, spending and possible entitlement to help. Cutting discretionary spending may create room, but it cannot solve every affordability problem. If the essentials still do not fit, that is useful information for a lender conversation, not a reason to postpone it.
Ask for alternative payment illustrations using your actual balance and circumstances. Keep the assumptions with each illustration, especially the repayment term and any fees. This makes it easier to see whether apparent relief comes from a different rate, a longer repayment period or temporarily paying less capital.
What can you ask your lender before missing a payment?
The FCA advises borrowers to contact their lender when they become concerned about affordability. Explain whether the pressure is temporary, linked to an expiring deal or likely to continue. A prepared budget gives the lender a clearer picture than a request for the smallest possible instalment.
Possible discussions include extending the repayment term or temporarily paying interest only. Availability depends on your circumstances and mortgage terms; these are not automatic entitlements. Ask for the consequences in writing before agreeing to a change.
| Possible arrangement | Potential benefit | Important trade-off |
|---|---|---|
| Longer repayment term | A lower regular payment | More interest overall and borrowing that lasts longer |
| Temporary interest-only payments | Short-term payment relief | No capital reduction during that period and higher payments afterwards |
| A replacement mortgage deal | A different rate or payment structure | Fees, eligibility checks and contractual restrictions can matter |
If a longer term would run beyond your expected retirement, ask what income evidence and affordability checks apply. For temporary support, establish when normal repayments restart and what they will be. Relief now can otherwise create a payment problem later.
Checking alternative deals is a separate part of the decision. Our guide to the costs and conditions of switching a UK mortgage deal explains why the advertised rate is not the whole comparison. Do not assume that leaving an existing fixed deal early is free.
Will asking for mortgage support affect your credit file?
The FCA distinguishes discussing help from changing the repayment arrangement. In its guidance on support for struggling mortgage borrowers, the regulator says that talking through options does not itself damage your credit file. That does not mean every subsequent agreement has no reporting consequences.
Ask how the specific proposal will be recorded and whether it changes the contractual payment. An arrangement to pay less than the agreed amount can appear on your file. Request an explanation of reporting alongside the new payment schedule, rather than relying on a general reassurance about support.
If a payment has already been missed, explain that immediately. Continue payments you can afford in line with your agreement while discussing next steps; a conversation alone does not change the contract.

Frequently Asked Questions
Not simply because market rates rise while your agreed fixed period is still running. The important point is when that fixed period ends and which rate applies next. Check your contract and ask the lender for the future payment rather than assuming a news headline describes your mortgage.
No. Spreading repayment over a longer period can reduce the regular instalment while increasing the total interest paid. Compare the overall cost as well as the immediate payment. Consider whether the extended schedule would continue into retirement and ask the lender how affordability would be assessed.
You can contact the lender before a payment is missed, and the FCA encourages early conversations when affordability becomes a concern. Bring your budget, mortgage details and expected income changes. Waiting for arrears is not a condition of discussing options, although the support available depends on individual circumstances.
No. This article describes UK guidance and uses an England-specific Citizens Advice resource for budgeting context. Canadian borrowers need information relevant to their own lender, mortgage contract and regulatory setting. Do not treat a UK reversion-rate explanation or lender-support discussion as a statement of Canadian renewal rights.
