Which mortgages move
What a Bank Rate change does to your mortgage
- Base-rate tracker: set at Bank Rate plus a fixed margin, so a 0.25-point move in Bank Rate moves your rate by 0.25 points. Your mortgage offer says from when.
- Standard variable rate (SVR): your lender decides whether and how far to move it. Many follow Bank Rate, but they do not have to.
- Fixed rate: your payment stays the same until the fixed deal ends. A change matters when you remortgage, because new fixed deals are priced on expected future rates.
How it is worked out: monthly repayment = balance × r ÷ (1 − (1 + r)^−n), where r is your annual rate ÷ 12 and n is the months left. Interest-only = balance × annual rate ÷ 12. Payments are rounded to the penny. Your lender’s figure can differ slightly (fees, daily interest, the day the change starts).
Recent decisions (Bank of England, checked 31 October 2026): Bank Rate held at 3.75% on 18 June, 30 July and 17 September 2026. 2026 decisions still to come: 5 November and 17 December. Bank of England: upcoming MPC dates.

Bank Rate and mortgage FAQs.
When is the next Bank of England interest rate decision?
Thursday 5 November 2026. The Bank usually announces at 12:00 noon UK time. The one after is Thursday 17 December 2026 (Bank of England MPC dates).
What is the Bank of England base rate now?
Bank Rate is 3.75%. The Monetary Policy Committee held it at 3.75% on 17 September 2026.
How much will my mortgage go up if the base rate rises 0.25%?
It depends on what you owe and for how long. On a £200,000 repayment mortgage over 25 years at 5%, a 0.25-point rise adds £29.32 a month (£351.84 a year), from £1,169.18 to £1,198.50. On a fixed rate nothing changes until the deal ends.
Will my mortgage go down if the Bank cuts rates?
A base-rate tracker falls by the same amount. On £200,000 over 25 years at 5%, a 0.25-point cut lowers the payment by £28.95 a month. An SVR falls only if your lender passes it on; a fixed rate does not change.
Does this page predict the decision?
No. It shows what a move of 0.25 or 0.5 points in either direction would do, and the no-change row. Only the Bank of England’s Monetary Policy Committee decides.
