Your Fixed Mortgage Deal Ending Soon? Here's How to Save Up to £3,000 a Year Before It's Too Late

📅 18 September 2026⏱️ 5 min read✍️ Terry the Turtle

Millions of UK homeowners are rolling off cheap fixed mortgage deals right now — and many are sleepwalking into paying hundreds of pounds more every month. Terry the Turtle explains exactly what to do, and when to do it.

If your fixed-rate mortgage deal is ending in the next six to twelve months, this is genuinely one of the most important financial conversations you can have right now. Across the UK, millions of families who locked in at ultra-low rates of 1% or 2% a few years ago are suddenly facing deals at 4%, 5% or even higher. On a typical £200,000 mortgage, that can mean paying £200 to £400 more every single month. That's money that could be going towards your family, your savings, or just making life a little easier. The good news? If you act early and smartly, you can soften the blow significantly — and Terry is here to show you how.

Understanding What Happens When Your Fix Ends

When your fixed-rate deal finishes, your lender doesn't just leave you on a nice rate out of the goodness of their heart. You automatically roll onto something called the Standard Variable Rate — or SVR. This is the lender's default rate, and it is almost always much higher than anything you could get by shopping around. We're talking rates that can sit anywhere between 7% and 9% at the moment. Staying on the SVR even for just a few months could cost you an extra £500 to £1,000 you simply didn't need to spend. The fix is simple: don't let it happen by accident.

Start Shopping Around Up to Six Months Early

Here's something most homeowners don't realise — you can lock in a new mortgage deal up to six months before your current one ends, with many lenders now offering a window of up to six months. That means if your deal ends in March, you could be securing your new rate right now in September. And if rates drop between now and March? Many lenders will let you switch to the lower rate before completion at no extra cost. It's a brilliant way to protect yourself from rate rises while still keeping the door open if things improve. There is absolutely no reason to wait until the last minute.

Should You Stay With Your Lender or Switch?

Your existing lender will almost certainly write to you with a new deal offer — and it might look tempting because it's familiar and feels easy. But easy is not always best. The difference between your lender's retention offer and the best deal on the market could easily be 0.5% to 1%. On a £200,000 mortgage over a two-year fix, that's a difference of £2,000 to £3,000 in interest payments. Always, always compare what's out there before you accept anything. A good mortgage broker can do this legwork for you, often for free, and has access to deals you simply cannot get by going direct to lenders yourself.

Fixed or Variable — What's Right for You Right Now?

Most people feel safer with a fixed rate because you know exactly what you're paying each month — brilliant for budgeting when life is already expensive enough. Two-year and five-year fixes are the most popular choices. A two-year fix gives you flexibility to remortgage again sooner if rates fall, while a five-year fix gives you longer-term certainty. There's no single right answer — it depends on your own situation, your plans for the property, and your appetite for risk. The important thing is to make an active choice, not to drift onto the SVR by doing nothing.

Terry's Top Tips 🐢

  • Diarise your end date today. Check your mortgage paperwork and mark the date your fix ends. Set a reminder six months before so you don't forget to act.
  • Never just accept your lender's first offer. It might not be the best rate available to you. Always get a comparison first.
  • Use a whole-of-market broker. They search thousands of deals and can often find rates not available directly to the public — and many charge you nothing at all.
  • Check your credit file before you apply. A healthier credit score means access to better rates. Fix any errors now rather than being surprised later.
  • Think about overpaying if you can. Even small overpayments while you're still on a low rate can reduce your balance and lower your repayments on your next deal.
