If your fixed-rate mortgage deal is ending in the next six to twelve months, this is one of the most important things you can read right now. We're talking about the difference between paying an extra £200, £300, even £400 a month — or not. That's real money, the kind that pays for food, energy bills, or a family holiday. The good news? A little bit of forward planning can make a massive difference. Let me walk you through it, step by step.
Why Rolling Onto Your Lender's Standard Rate Is a Trap
When your fixed deal ends, your lender doesn't just sit you down for a chat and find you the best option. Instead, you automatically roll onto something called the Standard Variable Rate — or SVR. Right now, many lenders' SVRs sit somewhere between 7% and 9%. If your old fixed rate was 2% or 3%, that jump can add hundreds of pounds to your monthly payment almost overnight. Lenders rely on homeowners not paying attention. Don't be one of them. The moment your fix ends, and you haven't switched, you're almost certainly paying over the odds.
The Six-Month Rule — Start Looking Earlier Than You Think
Here's the thing most people don't realise: you can lock in a new mortgage rate up to six months before your current deal ends. That means if your fix runs out in, say, October, you should be shopping around right now. Mortgage rates do move around, but if you secure an offer today and rates drop before your deal starts, many lenders will let you switch to the lower rate. If rates go up, you're already protected. It really is one of those rare situations where acting early has no downside. Set a reminder in your phone right now — six months before your end date — and treat it like an important bill that needs paying.
Should You Stay With Your Current Lender or Switch?
This is the question everyone asks. Staying with your existing lender — called a product transfer — is quick, simple, and involves very little paperwork. There's no new affordability check in most cases, which matters a lot if your financial situation has changed since you first took out your mortgage. But — and this is a big but — your current lender is not always offering you the best deal on the market. Research consistently shows that people who shop around and switch lender can save significant sums. The answer? Always check what your current lender is offering, then compare it against the whole market. Never just accept the first renewal letter that lands on your doormat. That letter is written to make life easy for the lender, not for you.
The Value of a Good Mortgage Broker
A whole-of-market mortgage broker can access deals you simply cannot find on your own. Many high street lenders offer exclusive rates only through brokers. A decent broker will compare hundreds of deals, explain the true cost including fees, and handle all the paperwork. Lots of brokers offer a free initial consultation, and some are fee-free entirely, earning their money from the lender instead. For most people, speaking to a broker before their fix ends is one of the best financial decisions they can make. Half an hour of your time could genuinely save you thousands over the next two to five years.
Terry's Top Tips
- Diary it now: Mark six months before your fix ends in your calendar and commit to starting your mortgage search on that date.
- Know your numbers: Find out your current deal's end date, your remaining balance, and your home's approximate value before you speak to anyone — it speeds everything up.
- Don't ignore the fees: A lower interest rate with a hefty arrangement fee isn't always cheaper than a slightly higher rate with no fee. Always compare the total cost over the deal period.
- Check your credit file: Before applying anywhere, make sure your credit report is accurate. Errors can cost you access to the best rates.
- Overpay if you can: If your deal allows it, making small overpayments now reduces your balance and can unlock better loan-to-value bands, meaning cheaper rates when you remortgage.
