Calculate Your Mortgage Payment Change
Frequently Asked Questions
How does the Bank of England base rate affect my mortgage?
The Bank of England base rate is the interest rate at which the Bank lends to commercial banks. It directly influences the cost of borrowing across the economy. For mortgages, it affects variable rate products most immediately. Tracker mortgages follow the base rate by a set margin automatically. SVR and discount variable mortgages are set by individual lenders and usually (but not always) move in the same direction as the base rate. Fixed-rate mortgages are unaffected during the fixed term.
Which mortgages change when the base rate changes?
Tracker mortgages: automatically change by the same amount as the base rate on a set date (usually within 30 days). Standard Variable Rate (SVR) mortgages: lenders can change them at will, but typically follow base rate moves broadly. Discount variable mortgages: move with the lender’s SVR. Fixed-rate mortgages: do not change during the fixed term, regardless of base rate movements. Offset mortgages and flexible mortgages: depends on whether the underlying rate is tracker, SVR, or fixed.
What is a tracker mortgage in the UK?
A tracker mortgage has an interest rate that is set at a fixed margin above (or occasionally below) the Bank of England base rate and automatically adjusts whenever the base rate changes. For example, a tracker at ‘base rate + 1.5%’ would charge 6.25% when the base rate is 4.75%. Trackers offer transparency because you know exactly how your rate will move. The downside is that your payments rise if the base rate increases, unlike a fixed-rate mortgage which provides certainty for the fixed term.
How much does a 0.25% rate change affect a mortgage?
On a £200,000 repayment mortgage with 20 years remaining, a 0.25% rate change alters the monthly payment by approximately £25–30 per month, or £300–360 per year. The exact impact depends on the outstanding balance, remaining term, and starting rate. Larger balances and shorter remaining terms amplify the monthly impact.

Bank of England base rate history and forecast for 2026
The Bank of England raised the base rate aggressively from 0.1% (December 2021) to a peak of 5.25% (August 2023) to combat inflation. Rate cuts began in August 2024, and by early 2026 the rate had reduced to approximately 4.5%. Most market forecasters as of early 2026 expect further gradual cuts through 2026–2027, with the base rate potentially reaching 3.5–4.0% by end-2027, depending on inflation and economic growth.
