UK mortgage rate rise fears are mounting as more than 2.3 million households brace for a sharp increase in payments when their fixed-rate deals expire in 2027. The Bank of England is expected to raise its base rate this week for the first time since December, adding further pressure on borrowers already squeezed by higher energy and food bills.
Why the Bank of England Is Set to Raise Rates
The Bank’s nine-member Monetary Policy Committee (MPC) is widely expected to increase the base rate from 3.75% to 4% on 5 November. This follows UK inflation rising to 3.5% in September, prompting concerns that price pressures are not easing quickly enough.
Financial markets anticipate this could be the first of four quarter-point rises over the next 12 months. If realized, the base rate would climb to 5% by late 2026, significantly raising borrowing costs for homeowners.
How Many Households Are Affected?
According to UK Finance, a banking industry body, 2.3 million households will reach the end of their fixed-rate deals next year. Additionally, around 700,000 borrowers were forecast to switch to new rates between July and December this year.
These borrowers face the prospect of remortgaging at higher rates, as swap rates—which influence fixed-rate mortgage pricing—have already risen due to bond market volatility. The volatility has been triggered in part by energy prices and inflation fears linked to the war in the Middle East.
What This Means for Your Mortgage Payments
For homeowners coming off fixed deals, the impact could be substantial. A rise in the base rate typically translates into higher monthly payments for those on variable or tracker mortgages, and it also pushes up the cost of new fixed-rate deals.
With inflation already eroding household budgets, an increase in mortgage payments could strain finances further. Mortgage approvals have already fallen to a near-decade low, indicating that the housing market is cooling as affordability worsens.

What Should Borrowers Do Now?
If your fixed-rate deal is ending in the next 12 months, start exploring remortgage options early. Lenders often allow you to lock in a new rate up to six months in advance, providing protection against further increases.
