Millions of UK households face higher mortgage bills as Bank of England set to raise rates

More than 2.3 million households are expected to see mortgage payments rise when fixed-rate deals end in 2027, after the Bank of England’s monetary policy committee is widely forecast to lift the base rate from 3.75% to 4% on 5 November following a rise in inflation to 3.5% in September.

Expectation of a rate rise

The Bank of England’s nine-member monetary policy committee is widely expected to raise the base rate from 3.75% to 4% on 5 November, after official figures showed UK inflation increased to 3.5% in September. Markets and economists have treated such a move as likely, citing the persistent inflationary pressure that the Bank seeks to tame.

Impact on households coming off fixed deals

More than 2.3 million households whose fixed-rate mortgage deals expire in 2027 are forecast to face a sharp increase in monthly payments when they remortgage. Many borrowers whose fixed deals come to an end move onto new fixed or variable products priced off prevailing interest rates, meaning an increase in the Bank’s base rate tends to feed through to mortgage costs.

Wider implications for borrowers and the housing market

Higher borrowing costs will squeeze household finances for many remortgaging borrowers, increasing the share of income needed to service mortgages. That pressure can reduce discretionary spending and alter decisions about moving home. Lenders typically adjust new product pricing to reflect changes in the Bank rate, which can leave borrowers searching for affordable alternatives or accepting higher repayment levels.

Policy outlook and economic context

The BoE has raised rates in recent years to counter inflation that has remained above its 2% target, and the expected November move would be another step in that direction. How long rates stay elevated will shape the scale and duration of impacts on mortgage holders and the housing market more broadly, as households and lenders adapt to a higher-cost borrowing environment.
