Mortgage Shock: 970,000 Homeowners Face £5,652 Annual Bill Increase
Around 970,000 borrowers who secured fixed-rate mortgage deals below two per cent back in 2021 are now facing a steep annual rise in their bills, with potential increases of up to £5,652. This refinancing shock comes as interest rates have climbed significantly, leaving many households vulnerable to higher housing costs.
Rising Rates and Financial Pressure
The average two-year fixed mortgage rate climbed above five per cent last week for the first time since August 2025, while five-year fixed products reached 5.1 per cent. Standard variable rates stood at a high of 7.24 per cent, exacerbating the financial strain on homeowners.
According to Compare the Market, homeowners whose five-year fixed deals are ending this year could see their annual repayments jump by as much as £5,652 if they move onto the average variable rate. Even those opting for a new five-year fixed deal would still face additional costs of at least £2,300 annually.
Expert Insights on the Refinancing Crisis
Charlie Evans of Compare the Market highlighted that borrowers exiting ultra-low five-year arrangements are confronting an "even more severe" rise in their yearly costs than previously anticipated. "These households were already on track to see average annual repayments rise. But with rates climbing further... these borrowers are potentially facing a stark refinancing shock," he said.
Lucian Cook, the head of residential research at Savills, added, "In a market where homeowners are fixing their mortgages for longer, the impact of higher interest rates on housing costs – and on households’ ability to spend elsewhere in the economy – tends to have a much longer tail."
Housing Market Context and Future Outlook
According to the property website Rightmove, new seller asking prices have risen by an average of £3,023 in March to £371,042, a "typical" seasonal increase of 0.8%. The number of homes for sale remains at an 11‑year high for this time of year, and Rightmove described the market as "steady" despite global uncertainty created by the Iran conflict.
Cook further noted, "Until recently, 2026 looked set to offer some respite, but that is now less certain given the prospect of another wave of inflation, which mortgage markets are typically quick to price in." This uncertainty adds to the challenges faced by homeowners navigating the current economic landscape.
