The Bank of England has increased interest rates to 4%, a move that could push up monthly mortgage repayments for households already struggling with rising living costs. The Bank's Monetary Policy Committee (MPC) raised the base rate by 0.25 percentage points from 3.75% on Thursday (November 5), marking the first increase in more than three years.
Inflation and Energy Costs Drive Decision
The decision comes after UK inflation reached 3.5% in September, remaining well above the Bank's 2% target. Higher energy costs linked to the ongoing conflict in the Middle East have added to concerns about further price increases.
The rise will have an immediate impact on homeowners with tracker mortgages, which follow movements in the Bank Rate. Borrowers on standard variable rates could also see their monthly repayments increase if lenders pass on the rise.
Homeowners with fixed-rate mortgages will not see an immediate change, although those approaching the end of their current deals could face higher borrowing costs when they remortgage.
Reaction from Industry Experts
Jenny Holt, Customer Savings & Investment Director at Standard Life, said: “For households already feeling the strain of rising bills, today’s interest rate increase will be unwelcome news, particularly for those with mortgages or other borrowing.
“With inflation reaching 3.5% in September and energy costs continuing to squeeze household budgets, the Bank has judged that further action is needed to bring price pressures under control.”
She added: “For mortgage holders, the impact will be most immediate for those on tracker rates, while some borrowers on variable rates could also see their repayments rise. Anyone approaching the end of a fixed-rate deal should review their options early and understand what a higher rate could mean for their monthly budget.”
Impact on Savers and Tax Changes
The increase could also provide some welcome news for savers, although banks and building societies are not required to pass on higher interest rates to customers.
Jason Hollands, Managing Director of online investment platform Bestinvest, warned that higher savings returns could result in more people paying income tax on their interest. He said: “This widely expected rate rise may be welcomed by savers, but more will find that their savings interest exceeds their annual Personal Savings Allowance.
“The Personal Savings Allowance has remained unchanged since it was introduced in 2016, while savings rates have risen sharply in recent years as the Bank of England has raised the base rate to tackle inflation.”
Under current rules, basic rate taxpayers can earn £1,000 in savings interest each tax year without paying income tax, while higher rate taxpayers have a £500 allowance. Additional rate taxpayers do not receive a Personal Savings Allowance.
The latest interest rate increase also comes just over a week after Chancellor John Healey announced changes to the taxation of savings income in the Autumn Budget. From April 2027, income tax rates on savings interest above the relevant tax-free allowances will rise to 24% for basic rate taxpayers, 44% for higher rate taxpayers and 49% for additional rate taxpayers.
Mr Hollands urged savers to consider tax-efficient accounts, including Cash ISAs, which allow people to earn interest without paying income tax. He said: “Using an ISA is one of the simplest ways to shelter savings interest and investment returns from tax.”
The annual ISA allowance remains at £20,000 following the UK Government's decision to abandon plans to reduce the Cash ISA limit in last month's Budget.
Outlook for Future Rate Moves
Meanwhile, Ms Holt cautioned that today's increase does not automatically mean another rise is imminent. She said: “The Bank faces a difficult balancing act. Ongoing conflict in the Middle East continues to create uncertainty around global energy prices, complicating efforts to bring inflation back towards its 2% target.
“At the same time, hiring remains subdued and the outlook for economic growth is uncertain.”
The Bank of England's next interest rate decision is scheduled for December 17.
