TL;DR
In short
- Bank Rate influences borrowing costs but is not the interest rate on every mortgage.
- Trackers and lender-set standard variable rates work differently.
- A fixed-rate payment generally stays unchanged during its agreed fixed period.
- Future rate decisions are uncertain; this guide does not forecast them.
- Compare total costs, fees, eligibility and flexibility before changing a mortgage.
This evergreen guide explains how Bank Rate changes can affect mortgage costs. It is not a forecast of the next decision or a recommendation to choose a fixed or variable rate. Check the Bank of England for the current rate and decision date.

Interest rate increase in the UK. How will it affect the mortgage market?
What is the interest rate?
Interest is the cost of borrowing and the return on saving. Bank Rate is set by the Bank of England and influences wider interest rates; it is not the rate every mortgage customer pays. See What are interest rates?.
Mortgage pricing also reflects funding costs, market expectations, lender margins and product criteria. The effect depends on the type of mortgage, not just the latest Bank Rate announcement.
Why can Bank Rate change?
Central banks use monetary policy to pursue their objectives, including price stability. Decisions differ between economies and over time; a past increase does not establish what the Bank of England will do next.
Higher rates tend to discourage borrowing and spending and encourage saving, helping reduce inflation over time. The effects are uncertain and delayed. See the Bank of England’s inflation explanation and explainers.
Can the next Bank Rate decision be predicted?
The next change is not certain. The Monetary Policy Committee assesses inflation and economic developments; this article does not predict an increase or decrease.
Use a household budget that allows for different future rates rather than relying on an undated forecast. Your needs, repayment capacity and product terms matter more than a general prediction.
How can rate changes affect different mortgages?
Tracker rates normally move in line with the reference rate specified in the contract. A standard variable rate is set by the lender and need not move identically. An existing fixed-rate payment generally stays unchanged until its fixed period ends, unless other contractual changes apply.
At the end of a deal, compare a product transfer with remortgage options using the total cost, eligibility, fees and any early repayment charge. A new offer may be higher or lower than the expiring rate; refinancing is not guaranteed.

How should fixed and variable rates be compared?
A fixed rate provides payment certainty for the agreed period; a variable rate can move up or down according to its terms. Compare costs, flexibility, your plans and affordability. There is no universally suitable choice based only on the latest Bank Rate decision.
