Mortgage Deal Ending in 2026? Here's What to Do

Knowing what to do when fixed rate mortgage ends UK is one of the most urgent financial questions facing British homeowners right now. The average five-year fixed mortgage rate hit 6% for the first time in three years on October 5, 2026, and around 1.8 million mortgage holders will reach the end of their fixed-rate period this year. Almost a million of them are remortgaging for the first time since rates spiked in September 2022, stepping off a sub-2% or sub-3% deal and landing in a market where six percent is the norm.

If that describes your situation, this guide covers every option available to you and what the current numbers mean for your decision.

What to Do When Fixed Rate Mortgage Ends UK: The Short Answer

The moment your fixed deal expires, your mortgage moves automatically to your lender's standard variable rate (SVR) unless you act first. SVRs are currently running between 7.5% and 8.5% at most major lenders, which is significantly higher than the best remortgage deals on the market today. The short answer is: do not drift onto the SVR. Lock in a new deal before your current one ends.

The longer answer depends on which option is right for your situation, and that is what the rest of this guide covers.

Why UK Mortgage Rates Are Rising Again (October 2026 Update)

Global bond markets have been volatile through the second half of 2026, pushing up swap rates (the benchmark lenders use to price fixed mortgages), and that cost is being passed directly to borrowers.

The numbers are stark. At the start of September 2026, there were 1,494 fixed mortgage deals priced below 5%. By the first week of October, that number had collapsed to just nine. The average five-year fixed rate hit 6.00% on October 5, its highest point since September 2023.

This is not a repeat of the mini-budget crisis of 2022, when rates spiked suddenly and unpredictably. The current rise is slower and driven by ongoing geopolitical pressures, a stickier-than-expected inflation picture in the US affecting global bond yields, and a Bank of England that has held rates higher for longer than the market expected.

For borrowers, the practical effect is the same: the deals available today are significantly more expensive than the ones most people signed up for two or five years ago, and the window of cheap fixes has largely closed.

Your 3 Options When the Fixed Rate Expires

When your deal ends, you have three realistic choices. This is the core of what to do when fixed rate mortgage ends UK, and understanding each option is where every borrower should start.

Option 1: Remortgage to a New Fixed Deal

This is what most borrowers will do. You switch, either with your existing lender (a product transfer) or to a new lender (a full remortgage), to a new fixed deal with a set rate for two, three, or five years.

The advantage is certainty. You know exactly what your monthly payment will be for the duration of the fix. Given the current direction of rates, locking in now before any further rises could save you considerably over the fixed period.

The consideration: if rates fall significantly after you fix, you are stuck at the higher rate until your deal ends (or you pay an early repayment charge to exit). Most fixed deals currently carry exit fees calculated as a percentage of your outstanding balance, often 1% to 5% depending on how early you leave.

Option 2: Product Transfer With Your Existing Lender

A product transfer is a remortgage that stays with your current lender. The application process is usually simpler (no full affordability assessment in most cases, no solicitor required, lower or zero fees), and your lender may offer rates not available through the open market.

The downside is that you are not comparing the whole market. Your lender's product transfer rates may not be the best available. Speaking to a whole-of-market broker before accepting a product transfer offer is worth doing, even if you end up going back to your lender anyway.

Option 3: Do Nothing (Move to SVR)

If you take no action when your fixed deal ends, you move to the SVR automatically. This is rarely the right choice in the current environment. With SVRs running at 7.5% to 8.5% and the best remortgage deals available at 4.5% to 5.5% depending on your loan-to-value ratio, the monthly difference on a typical mortgage can run to several hundred pounds.

There are edge cases where staying on the SVR briefly makes sense: if you are selling your property within the next three months, or if you are expecting a large payment that will allow you to pay off the mortgage entirely. Outside of those situations, moving to SVR and sitting there is an expensive mistake.

How to Find the Best Remortgage Deals Right Now

Start with a whole-of-market broker. A whole-of-market mortgage broker has access to deals from across the market, including some lenders who do not sell directly to the public. The broker fees vary (some charge a flat fee, others are paid by commission from the lender, some offer both), but the difference between the best and the third-best deal across a 25-year mortgage can far outstrip any fee. Look for brokers authorised by the Financial Conduct Authority (FCA) and registered on the FCA register.

Use comparison tools for a baseline. Sites like MoneySuperMarket, Moneyfacts, and L&C Mortgages give you a read on what is currently available based on your loan-to-value (LTV) ratio and outstanding balance. These are useful for getting a ballpark, but they do not show the full market.

Check your LTV. Your loan-to-value ratio determines which rate band you fall into. If your property has increased in value since you took out your mortgage, your LTV may have improved, potentially moving you into a better rate tier. Getting an updated valuation is worth doing before you start comparing deals.

Look at fee structures carefully. A lower rate with a higher arrangement fee is not always cheaper than a slightly higher rate with no fee. Always calculate the total cost over the fixed period, including any arrangement fees, valuation fees, and legal fees, rather than comparing headline rates in isolation.

Ask about rate reservations. Most lenders let you lock in a new rate up to six months before your current deal expires, without paying any early repayment charges. With rates currently moving upward, reserving early gives you a ceiling without committing you if rates fall.

Should You Fix for 2 or 5 Years in This Market?

This is the question every borrower is wrestling with right now, and there is no single right answer. Here is how to think it through.

The case for a 2-year fix: If you believe mortgage rates will fall over the next 24 months as the Bank of England cuts rates and the economic picture settles, a two-year fix lets you remortgage again in 2028 or 2029 when rates may be lower. You pay a slight premium for that flexibility, but if your prediction is right, you come out ahead.

The case for a 5-year fix: If rates stay elevated or rise further, locking in for five years at today's rates protects you through the full period. Five-year deals are currently priced attractively versus two-year deals in most LTV bands. You also reduce the cost and administrative effort of remortgaging again in two years.

The current market view: Most mortgage broker commentary in October 2026 leans toward the five-year fix for borrowers who do not expect to sell or make major changes in the next five years. Rates forecasters are split on whether the Bank of England will cut enough over the next 24 months to make a two-year deal the better bet. The uncertainty itself is a reason to lock in longer.

If you are unsure, a fee-free mortgage broker can model both scenarios against your specific balance, income, and plans. That 30-minute call can easily be worth several thousand pounds over the life of the deal.

What If You Cannot Afford the New Rate?

This is a real concern for borrowers moving from sub-2% fixes signed in 2020 or 2021. A household that fixed at 1.8% on a £250,000 mortgage was paying around £1,040 a month on a 25-year repayment basis. At 5.5%, that same mortgage costs around £1,530 a month. That is a nearly £500 monthly increase hitting at the same time as elevated energy bills and a higher cost of living.

If affordability is a concern, there are several routes worth knowing about.

Talk to your lender before your deal ends. Under FCA rules introduced after the 2022 spike, lenders are required to offer support to borrowers in financial difficulty. Options may include temporarily switching to interest-only payments, extending the mortgage term to reduce monthly payments, or a payment deferral in severe cases.

Extend the term. Extending your mortgage from 20 remaining years to 25 years reduces the monthly payment at the cost of paying more interest overall. This is a legitimate tool for managing cash flow, particularly if you plan to make overpayments when your situation improves.

Check your eligibility for the Mortgage Support Scheme. The government's existing support mechanisms for struggling mortgage holders, including the Mortgage Interest Relief scheme for benefit recipients, are worth checking if your income has dropped significantly. Citizens Advice and StepChange both offer free mortgage debt advice.

Conclusion: What to Do When Fixed Rate Mortgage Ends UK

The most expensive thing a borrower can do right now is nothing. Drifting onto the SVR when your deal expires could cost you hundreds of pounds a month compared to the best remortgage deals available today.

The process of remortgaging is simpler than most borrowers expect. A whole-of-market broker can do most of the work for you, and the time investment is a few hours of form-filling spread across two or three weeks. The financial return on that time is substantial.

Start six months before your current deal ends if you can. That window gives you access to rate reservations, enough time to handle any complications without pressure, and the best chance of securing a competitive deal before conditions change again.

UK mortgage rates in October 2026 are the highest in three years. The market is not going to hand you a good deal passively. Taking action this month, not next quarter, is the move.
