When should you remortgage in the UK?
Start looking around 3–6 months before your fixed deal ends — otherwise you roll onto your lender’s SVR, which is usually far more expensive. Here’s the timeline.
“Remortgaging” means switching your mortgage to a new deal — either with a new lender (a remortgage) or your existing one (a product transfer). Timing it right is the single biggest thing you can do to avoid overpaying.
Why the timing matters
When your fixed or tracker deal ends, you don’t stay on that rate. You roll onto your lender’s standard variable rate (SVR) — a default rate that’s usually significantly higher and can move up at any time. Every month on the SVR is typically money you didn’t need to spend.
The remortgage timeline
- 6m6 months before your deal endsA new deal offer is often valid for up to six months, so this is the earliest useful point to start comparing rates.
- 3m3 months beforeLine up your new deal or product transfer so it’s ready to start the day the old one ends — the sweet spot for most people.
- 0Deal endsYour new rate takes over. Do nothing and you’re on the SVR from this day.
Remortgage vs product transfer
| Product transfer | Remortgage | |
|---|---|---|
| Who | Your current lender | A new lender |
| Speed | Fast, fewer checks | Fuller application |
| Rate | Convenient, may be higher | Often more competitive |
| Best when | You want simple and quick | You want the best rate and can shop around |
It’s usually worth getting a product-transfer quote from your lender and comparing the wider market before deciding.
In short
Treat your deal-end date as a hard deadline. Start comparing 3–6 months out, line up a new deal or product transfer to begin the day the old one ends, and you’ll usually skip the SVR entirely.
Frequently asked questions
What is an SVR?
The standard variable rate is the default rate your lender charges once a fixed or tracker deal ends. It can change at the lender’s discretion and is usually higher than a new fixed deal, which is why people remortgage before it kicks in.
Is a product transfer the same as remortgaging?
Not quite. A product transfer is a new deal with your existing lender — quick, with fewer checks. Remortgaging means moving to a new lender, which can offer a better rate but involves a fuller application. It’s worth comparing both.
Can I remortgage early?
You can, but if you’re still inside a fixed deal you may face an early repayment charge. Most people time a new deal to start the day the old one ends to avoid both the charge and the SVR.
