Across the United Kingdom, a significant number of homeowners are facing the end of their two- and five-year fixed rate mortgage deals in 2026. This transition can have serious financial consequences, especially in the current interest rate environment. Understanding what happens when a fixed rate period ends, the risks associated with a lender’s standard variable rate (SVR), and the benefits of remortgaging can help homeowners make informed decisions and protect their financial well-being.

When a homeowner’s fixed rate mortgage deal expires, the loan typically reverts to the lender’s SVR unless a new deal is arranged. The SVR is a variable interest rate set by the lender, which often tracks changes in the Bank of England’s base rate, but can be adjusted at the lender’s discretion. This rate is usually much higher than available fixed or tracker deals, meaning monthly payments can rise sharply for those who do not remortgage in time. For example, an SVR can be several percentage points above the current base rate, resulting in hundreds of pounds in additional monthly payments for the average homeowner.

Allowing a mortgage to revert to the SVR presents clear risks. The most immediate impact is a jump in monthly repayments, which can strain household budgets and reduce disposable income. Unlike fixed rates, which offer certainty over monthly payments, the SVR can fluctuate, making it difficult for homeowners to plan their finances. Lenders can change the SVR at any time, and if the Bank of England raises its base rate, SVRs often rise quickly in response. This lack of predictability exposes homeowners to financial shocks, particularly if they are unprepared for sudden increases.

Remortgaging before the end of a fixed rate deal is usually encouraged to avoid these risks. Remortgaging means switching your existing mortgage to a new deal, either with your current lender or a different provider. By locking in a new fixed rate or even a competitive tracker rate, homeowners can secure lower monthly payments and protect themselves from unexpected interest rate hikes. Many lenders offer incentives for remortgaging, such as free legal work or reduced arrangement fees, making the process more attractive and affordable.

Recent trends in the Bank of England’s base interest rate have heightened the importance of timely remortgaging. In the past few years, the base rate has increased as policymakers attempt to manage inflation and stabilize the economy but recently declines in the rate have occurred. Each increase in the base rate is quickly reflected in lenders’ SVRs, making them more expensive for borrowers. While fixed rate deals taken out five years ago may have benefited from historically low rates, those deals ending now are maturing into a higher interest rate environment. This means that reverting to SVR is likely to be even more costly.

The impact of fixed rate endings can differ depending on whether a homeowner is coming off a two- or five-year deal. Those who secured two-year fixed rates in 2024 did so when interest rates were higher than they are now, so their repayments with a remortgage could offer savings. Those who locked in five-year deals during the ultra-low rate period around 2021 could face repayments higher than they were used to paying. Homeowners coming off five-year fixed rates are particularly vulnerable to payment shocks, as their new rate could be significantly higher than what they have paid for half a decade. In both cases, failing to act before the fixed rate expires can lead to a sudden and substantial rise in costs.

Because of these risks, it is essential for homeowners to shop around for remortgage deals before their fixed rate ends. The mortgage market is competitive, and lenders frequently introduce new products or special offers to attract remortgaging customers. Comparing deals allows homeowners to find the most favorable rates and terms, potentially saving thousands of pounds over the life of the loan. Engaging with a mortgage broker or using comparison websites can help identify suitable options and ensure a smooth transition to a new deal. It is advisable to begin the remortgaging process at least three to six months before the end of the fixed rate period to avoid being placed on the SVR. However, even those already on a SVR could benefit by shopping as soon as possible.

For those who have already reverted to a SVR, it is not too late to act. While moving off a SVR may involve some paperwork and potentially fees, the long-term savings from securing a lower rate can far outweigh these costs. Homeowners on a SVR should review their options as soon as possible, as every month spent on a higher rate means more money spent unnecessarily. 

The end of two- and five-year fixed rate mortgage deals in 2026 demands prompt action from homeowners. Allowing a mortgage to revert to the SVR exposes borrowers to higher and unpredictable monthly payments. Remortgaging offers the opportunity to secure better rates, gain payment certainty, and protect household finances. Homeowners should start comparing remortgage deals well in advance of their fixed rate ending, and those already on SVR should prioritize finding a new deal. Taking proactive steps now can safeguard your financial future and provide valuable peace of mind.
