The Five Criteria That Determine Whether You Should Remortgage Now or Wait
Every remortgage timing decision reduces to five questions. Answer each honestly and the path forward usually becomes obvious.
- How close are you to the end of your current deal? Most lenders allow you to secure a new deal up to six months before your fixed rate ends. If you are inside that window, the question is not really 'now or wait', it is 'which rate to lock'.
- What is your current rate and what rate can you get today? If your existing rate is materially higher than today's market, acting now saves you money immediately. If it is materially lower, waiting usually wins.
- What early repayment charge (ERC) would you pay to break your existing deal? A 3% ERC on a £250,000 balance is £7,500 of pain. Unless the rate saving is enormous, breaking mid-term rarely pays off.
- What is your view on where rates are heading? Markets currently price two further 0.25% BoE cuts in 2026. That view is baked into today's fixed deals, so you only win by waiting if cuts come faster than expected.
- How much rate certainty do you need? If a 1% rate rise would stretch your budget, the insurance value of locking today outweighs small potential savings from waiting.
Score each criterion honestly. If three or more point toward acting, remortgage now. If three or more point toward waiting, hold off and monitor the market monthly.
Decision Matrix: Remortgage Now vs Wait
Use this matrix to cross-reference your situation against the recommended action. It captures the most common combinations we see in our broker network.
| Your situation | Current rate | ERC status | Recommended action |
|---|---|---|---|
| Deal ends in next 6 months | Any | No ERC or low ERC | Remortgage now; lock a rate you can drop if the market improves before completion |
| Already on SVR | 7.5% to 8.5% | No ERC | Remortgage now; every month on SVR burns £200 to £400 extra on a £200k balance |
| Mid-way through 5-year fix at 1.99% | 1.99% | ERC 3% to 4% | Wait; the ERC plus higher new rate will cost more than staying put |
| Mid-way through 2-year fix at 5.5% | 5.5% | ERC 1% to 2% | Run the numbers; breaking may pay off if you can secure a 4.3% fix |
| Moving to a tracker to stay flexible | Any | Any | Wait until within 3 months of deal end; trackers have no ERC so you keep optionality |
| Worried about rate rises affecting affordability | Any | Any | Lock a new deal within your 6-month window; stability outweighs marginal savings |
The matrix is a starting point, not a substitute for running the numbers on your specific balance, ERC and target term. The next section shows you how.
The Cost of Waiting: A Worked Example
Consider Sarah, who has £215,000 left on her mortgage over 22 years and is currently paying a 5.49% fixed rate that ends in July 2026. She is three months away from her deal ending and is wondering whether to lock a new rate today or wait until July.
Today she can secure a 4.29% five-year fix with Nationwide, with no ERC on her existing deal because she is inside her lender's six-month early switch window. Her existing monthly payment is £1,361. On the new 4.29% deal, her payment would fall to £1,215, a saving of £146 per month or £1,752 per year.
If she waits three months, the market expects one 0.25% BoE cut in that window. Historically, roughly 0.15% of a 0.25% cut filters through to fixed mortgage pricing. So by July the same deal might be available at 4.14%. On her balance that would be an extra £19 monthly saving compared with locking today.
But Sarah would have paid her higher 5.49% rate for three more months. That is £438 of additional interest. To break even on waiting she would need the July rate to be 4.12% or lower, not 4.14%. Unless cuts come faster than expected, she is better off locking today and using her lender's rate-drop facility if markets improve before completion.
The lesson: when you are inside your lender's 6-month early switch window, locking today and switching product later is almost always better than waiting.
