Thousands of Britons on fixed-rate mortgage will see their deal come to an end by the end of the year

Britons are due to be "thousands of pounds a year worse off" due to their low-interest fixed-rate mortgage deal coming to an end in the months ahead, according to new analysis.

Research conducted by budget management app Nous found that approximately 350,000 households secured five-year fixed-rate mortgages between October 2020 and February 2023, when interest rates were at historic lows.


These borrowers managed to avoid the rate spike that occurred two years ago, but now face substantial payment increases as their agreements conclude this winter.

Nous conducted analysis revealing that nearly half of all mortgages arranged during this period were five-year fixed arrangements.

Experts note the financial implications are severe for affected homeowners as interest rates on five-year fixed mortgages have surged from an average of 1.88 per cent in 2020 to five per cent currently.

For borrowers with standard £200,000 mortgages, monthly payments will increase by £333, reaching £1,169. This represents an annual cost increase of £3,996.

Those with larger mortgages face even steeper rises. Homeowners with £500,000 loans will see monthly payments climb by £833.

Greg Marsh, the chief executive of Nous, warned: "Hundreds of thousands of homeowners are in for an unpleasant shock this winter.

"The era of ultra-cheap mortgages is over. For these households, it's leaving them thousands of pounds a year worse off."

Despite the Bank of England reducing its base rate to four per cent in August, mortgage costs continue climbing.

Major lenders including Nationwide, Halifax and HSBC have recently increased their rates, typically adding 0.2 percentage points to fixed deals.

Adam French, the head of News at Moneyfacts, explained: "The Bank of England Base Rate may grab headlines, but there are many more rates and indices that influence the cost of borrowing."

He highlighted that swap rates, which banks use to price fixed mortgages, experience approximately 500,000 changes annually compared to just eight base rate decisions.

Water and council tax bills have already risen this year, with energy prices set to increase in October.

Hina Bhudia, a partner at Knight Frank Finance, noted that recent economic data has made further Bank of England rate cuts appear less likely.

Initial predictions of a November reduction have shifted to expectations of spring action.

Mr French suggested borrowers might see gradual cost reductions through year-end, though intermittent increases will occur as global economic factors increasingly influence lender pricing.

He advised that those seeking mortgages could monitor rates and potentially switch deals before completion if prices decline.
