Right now, hundreds of thousands of UK families are sitting on a financial time bomb and many don't even know it. If your fixed-rate mortgage deal is ending in the next six to twelve months, the rate you automatically roll onto — called the Standard Variable Rate, or SVR — could be dramatically higher than what you're paying today. We're talking an extra £200, £300, even £400 a month for some households. That adds up to thousands of pounds a year, straight out of your pocket. The good news? You absolutely don't have to let that happen. Let me walk you through exactly what to do.
What Actually Happens When Your Fixed Deal Ends?
When your fixed-rate period finishes, your lender doesn't just wave goodbye. They quietly move you onto their Standard Variable Rate. This is a rate the lender sets themselves, and right now SVRs from major UK lenders are sitting around 7% to 9%. If you locked in a deal a few years ago at 2% or 3%, you can see the problem immediately. Your monthly payments could jump substantially — and unlike your fixed rate, the SVR can go up or down whenever the lender feels like it. It's unpredictable, expensive, and entirely avoidable if you plan ahead.
The Golden Rule: Start Looking Six Months Early
Here's something most people don't realise — you can often lock in a new mortgage deal up to six months before your current one ends, and most lenders won't charge you a penny to do so. That means if your deal finishes in October, you could be sorting a new rate right now in April. This is genuinely important because mortgage rates move around a lot. By securing a rate early, you protect yourself if rates rise again. And if rates fall before you complete, many brokers can help you switch to a better deal before it starts. You've got nothing to lose by starting early, and potentially a lot of money to save.
Should You Stick With Your Current Lender or Switch?
Your existing lender will likely write to you with a retention offer — that's their way of keeping your business. It can be tempting to just accept it because it feels easy. But easy isn't always cheapest. Comparing your lender's offer against the whole market could save you a serious amount of money. Even a 0.3% difference in interest rate on a £200,000 mortgage means around £600 a year saved. Over a five-year fix, that's £3,000. It genuinely pays to shop around, and a good mortgage broker will do that legwork for you — often at no cost to you, because they're paid by the lender instead.
What About Overpaying While You're Still on Your Current Deal?
If you've got a bit of spare cash and your current mortgage allows it — most fixed deals let you overpay by up to 10% of your balance each year without penalties — it's worth considering. Overpaying reduces the amount you owe, which means when you remortgage, you might qualify for a lower loan-to-value bracket. Lenders offer their best rates to people borrowing a smaller percentage of their home's value. Dropping from 75% loan-to-value to 70% can unlock noticeably better rates. Even small overpayments now can make a meaningful difference to your options later.
Terry's Top Tips
- Diarise your end date right now. Find your mortgage documents, note when your fixed deal ends, and set a reminder to start comparing deals six months before that date.
- Never just roll onto the SVR. Even if you're already on it, you can remortgage away from it at any time — there's no penalty for leaving an SVR.
- Use a whole-of-market broker. They compare deals from dozens of lenders, not just one, and can often access rates not available directly to the public.
- Check your credit file before you apply. A cleaner credit history means better rates. Use a free service to check yours a few months before you need to remortgage.
- Don't panic, but do act. Rates are moving. The sooner you get informed, the more control you have over what you pay.
