The increases come amid rising inflation linked to the conflict in the Middle East, which has disrupted oil supplies and pushed up energy prices. Higher borrowing costs have also affected the housing market, with property prices recording their sharpest annual decline in more than three years.
Fixed Mortgage Rates Approach 6% As Household Costs Increase
According to figures from Moneyfacts reported by This is Money, the rise in mortgage rates has added approximately £2,000 to the annual cost of a typical £250,000 mortgage, bringing yearly repayments close to £20,000.
Borrowers taking out a two-year fixed-rate deal now face an additional £168 in monthly repayments, equivalent to £2,016 annually. Those choosing five-year fixed mortgages are paying £161 more each month, adding £1,932 to their annual costs.
The increases represent a marked change from expectations earlier in the year, when analysts anticipated falling borrowing costs as the Bank of England prepared to reduce interest rates.
Caitlyn Eastell, personal finance analyst at Moneyfactscompare.co.uk, said borrowers could face thousands of pounds in additional annual costs compared with the beginning of January. The impact has extended beyond mortgage repayments to the wider property market.
According to a report by Lloyds Banking Group, average UK house prices fell by 1.2% in the year to October 2026, marking the steepest annual decline since October 2023.
Sarah Coles, head of personal finance at AJ Bell, described the decline as a sign that the housing market had “succumbed to gravity”, with elevated borrowing costs discouraging prospective buyers.
She also warned that continued uncertainty surrounding international developments could place further upward pressure on fixed mortgage rates, which remain close to 6% across both two-year and five-year products.
Middle East Conflict and Inflation Reshape Interest Rate Expectations
The conflict involving Iran, which began at the end of February, has substantially altered the outlook for British interest rates.
Disruption to oil supplies, particularly through the Strait of Hormuz, has driven energy prices higher, contributing to inflationary pressures and increasing borrowing costs internationally.
Before the conflict, some forecasts suggested fixed mortgage rates could fall towards 3% during 2026 as the Bank of England reduced its benchmark rate. Instead, the central bank raised its official interest rate from 3.75% to 4% last week, its first increase since August 2023.
UK inflation has already reached 3.5%, an 11-month high and considerably above the Bank’s 2% target. According to the original report, Bank of England governor Andrew Bailey has left open the possibility of another increase before Christmas, amid concerns that inflation could exceed 6%.
Domestic business costs have also contributed to inflationary pressure. Measures introduced by Labour include a £25 billion increase in employers’ National Insurance contributions and minimum wage rises, with businesses passing higher costs to consumers.
Financial markets are now pricing in the possibility of interest rates reaching 4.5% or 4.75% by the end of 2027. Angela Kerr, director at the Homeowners Alliance, said the Middle East conflict had overturned earlier expectations of further rate cuts, leaving homeowners facing a markedly different borrowing environment.
