If your fixed-rate mortgage deal is ending in the next six months, please don't ignore this. Right now, hundreds of thousands of UK families are accidentally sleepwalking onto their lender's Standard Variable Rate (SVR) — and it's one of the most expensive financial mistakes you can make. We're talking about potentially paying hundreds of pounds more every single month than you need to. The good news? With a little bit of action today, you can keep that money where it belongs — in your pocket.
What Actually Happens When Your Fixed Deal Ends?
When your fixed-rate period finishes — whether that's a two-year or five-year deal — your lender doesn't just leave your rate alone. They automatically move you onto something called the Standard Variable Rate, or SVR. This is basically the lender's default rate, and it's almost always much higher than what you've been paying. The average SVR in the UK currently sits around 8%, compared to fixed deals that can be found closer to 4-5%. On a £200,000 mortgage, that difference could cost you an extra £250 to £400 every month. Over a year, that's up to £3,000 gone — just like that.
When Should You Start Looking for a New Deal?
Here's the thing that surprises most people: you can lock in a new mortgage deal up to six months before your current one ends. That's your golden window, and you should use it. Most mortgage offers are valid for between three and six months, so applying early means you can secure today's rate without any pressure. If rates happen to drop before your deal starts, a good broker can often switch you to the better offer anyway. So there's very little downside to starting early, and a huge potential upside. If you're within six months of your deal ending right now, this is your sign to get moving.
Should You Stay With Your Current Lender or Switch?
Your current lender will likely write to you with a renewal offer, and it might be tempting to just tick a box and stay put. Easy, yes. But smart? Not always. Lenders often reserve their best rates for new customers, not loyal ones. Shopping around — even just getting a couple of quotes — could save you a significant chunk of money. That said, switching lenders does involve more paperwork and sometimes fees, so it's worth weighing up the full picture. This is exactly why speaking to a whole-of-market mortgage broker is so valuable. They can compare thousands of deals across dozens of lenders in one go, often finding options you'd never spot on your own. And in many cases, the broker's advice is completely free to you, because they're paid by the lender.
What About Overpaying or Paying Off Your Mortgage Early?
If you've got some savings sitting around earning less than your mortgage rate, it might be worth considering overpaying on your mortgage — especially before you re-fix. Most fixed deals allow you to overpay by up to 10% of your balance each year without any penalties. Overpaying reduces your outstanding balance, which means when you come to remortgage, you might qualify for a lower loan-to-value bracket — and that usually means access to better rates. Every little bit helps, and it all adds up over time.
Terry's Top Tips
- Set a reminder right now — check when your fixed deal ends and put a date in your phone six months before it finishes. That's your action date.
- Don't just accept your lender's renewal offer without comparing it to what else is available. Loyalty rarely pays in mortgages.
- Use a whole-of-market broker — they do the hard work for you and can access deals you won't find on the high street.
- Check your loan-to-value ratio — if your home has gone up in value since you bought it, you might qualify for a much better rate than you think.
- Watch out for fees — a low interest rate with a high arrangement fee isn't always cheaper. Always look at the total cost over the deal period.
