Bank of England Expected to Raise Interest Rates to 4%

Rising energy costs and renewed inflationary pressure have put UK monetary policy on course for a potential tightening, with the Bank of England expected to increase its benchmark interest rate on Thursday, November 5, 2026. Analysts widely anticipate a rise from 3.75% to 4%, which would increase borrowing costs while potentially improving returns for savers.

The expected decision would mark the first interest rate increase since August 2023. The Monetary Policy Committee (MPC) has maintained the rate at six consecutive meetings, following earlier reductions from its 5.25% peak.

According to the latest inflation figures, the Consumer Prices Index (CPI) reached 3.5% in September 2026, compared with 3.1% in August. The latest reading remains substantially above the Bank's 2% inflation target, with higher petrol and diesel prices contributing to the acceleration, according to the Office for National Statistics.

The economic consequences of the US-Israel conflict with Iran have also contributed to higher international energy and fuel prices. Rising household energy bills and renewed oil price increases have added pressure to the UK's inflation outlook.

Chris Cheverall, head of UK at CMC Markets, said the central bank's challenge extends beyond the anticipated increase.

"The decision is increasingly less about whether rates reach 4% and more about what follows after that. A quarter-point rise is already widely expected, but the Bank now has to balance inflation that is still too high against an economy where the growth outlook has weakened sharply."

The potential increase would directly affect hundreds of thousands of mortgage borrowers. According to UK Finance, approximately 510,000 homeowners with tracker mortgages could face an additional £31 in monthly repayments following a 0.25 percentage point increase.

Another 470,000 borrowers with standard variable-rate mortgages could see monthly payments increase by approximately £14, depending on whether their lenders pass on the higher borrowing costs.

Customers with fixed-rate mortgages would not experience an immediate change in their existing monthly payments. However, future refinancing could become more expensive because lenders have already incorporated expectations of higher interest rates into new mortgage offers.

Moneyfacts reported that the average two-year fixed residential mortgage rate stood at 5.96% on November 4, while the five-year average reached 5.99%.

Mortgage broker L&C estimated that some homeowners refinancing a £200,000 mortgage over 25 years could pay nearly £5,000 more annually than borrowers who secured refinancing agreements in 2021. At that time, the average five-year fixed remortgage rate among the 10 largest lenders was 1.30%.

Rachel Springall of Moneyfacts highlighted the risks associated with choosing variable-rate borrowing instead of locking in a fixed mortgage agreement.

"The right choice ultimately depends on borrowers being confident they can stomach future rises. The devil is in the detail."

Beyond mortgages, changes to the Bank rate can influence interest charged on credit cards, personal loans and vehicle financing. Banks and building societies also adjust their savings products in response to changes in the central bank's benchmark rate.

Moneyfacts reported that on November 4, the average easy-access savings account rate for a £10,000 balance was 2.58%. Easy-access cash ISAs averaged 2.79%, while one-year fixed savings accounts offered an average return of 4.48%.

The expected November increase follows a significant shift in monetary policy expectations. Earlier forecasts anticipated two interest rate reductions during 2026, but rising energy prices and persistent inflation have changed expectations, with analysts also anticipating another possible increase early next year.

The Bank of England is scheduled to announce its monetary policy decision at 12:00 GMT on Thursday, November 5, 2026, alongside guidance on the future direction of interest rates.
