Remortgage Reminder
Santander UKRecorded a lower monthly payment than the renewal quote.
A dated note on how FCA rules govern lender communications at the end of a fixed-rate mortgage deal and why the end date itself is the active decision point.
Published 1 January 2026
FCA rules in the Mortgages and Home Finance: Conduct of Business sourcebook (MCOB) govern how lenders communicate at the end of a fixed-rate deal and how the reversion rate is disclosed.
Reversion rates move with lender funding costs, which are anchored to the Bank of England Bank Rate over time — so the reversion rate published on the original mortgage offer is rarely the rate that actually applies on the day.
On the day after the fixed-rate end date, the mortgage typically reverts to the lender's standard variable rate. That reversion rate is usually higher than the original fixed rate and recalculates the monthly payment.
Any early repayment charge window that ends near the same date frames how early a remortgage can be completed without a penalty, so the end date is a hard anchor for the decision either way.
It is on the original mortgage offer and on the most recent annual statement.
This is what applies from the day after, if no action is taken.
Acting too early can trigger an ERC; acting too late means the SVR applies.
