Mortgage fixed rates end on a set date. The next payment can be much higher.
A fixed-rate mortgage protects your payment for a period of time. When it ends, your rate and monthly payment can change unless you arrange the next step in time.

Fixed-rate endings can create payment shock
+£180/month
The Bank of England said a typical borrower whose fixed deal ends by the end of 2026 could pay about £180 more each month, a 28% increase. This is one of the clearest timing risks Onremind covers: the date is known, the consequence can be large, and early review matters.

How mortgage rate changes work
Most residential mortgages are taken on fixed rates lasting 2–5 years.
During the fixed term, the interest rate is locked and monthly payments are predictable.
When the fixed period ends, the mortgage reverts to the lender's Standard Variable Rate (SVR) or a follow-on rate.
This reversion happens automatically on a fixed date.
The SVR is almost always higher than the fixed rate you were paying.
The problem isn't awareness.
It's timing.

Mortgage overpayment usually does not happen because someone ignored the market. It happens because a fixed deal ends, the intention to review is there, life gets busy, and the default rate takes over before the decision happens.

Common renewal patterns
These outcomes are predictable — and avoidable if you act before the renewal date.
Fixed rate ends
When the fixed period expires, the mortgage reverts to the lender's SVR — usually significantly higher.
The fixed-rate end date is the trigger point.
Product transfer missed
Lenders often offer product transfers before the deal ends. Missing the window means a higher follow-on rate.
The decision window closes at the fixed-rate end date.
Intro fees end
Some deals include introductory fee discounts that expire, causing monthly payments to rise.
The discount end date is fixed from the start.
Remortgage window missed
Remortgaging takes weeks to arrange. Starting too late means the SVR applies in the interim.
Early action is needed before the fixed term expires.
