UK households faced unprecedented financial pressure in 2025, as new figures reveal that total housing costs soared to a staggering £226 billion. This increase has been significantly influenced by a sharp rise in mortgage interest payments, leaving many borrowers struggling as they transition from fixed-rate deals.
Escalating Housing Costs
According to a report by property consultancy Savills, housing expenses have surged by £66 billion over the past five years, marking a 41% increase. The latest data indicates that last year alone saw an increase of nearly £8 billion, or 3.6%, in total housing costs, a slowdown compared to the previous years’ jumps of £22 billion in 2023 and £19 billion in 2024.
A particularly concerning aspect of this financial landscape is the 9% rise in mortgage interest payments, which climbed to £53.6 billion in 2025. This surge accounted for over half of the total increase in housing costs, putting additional strain on homeowners.
Impact on Borrowers
Lucian Cook, head of residential research at Savills, noted that the prolonged nature of fixed mortgage terms means the effects of rising interest rates can linger longer than anticipated. “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,” he explained.
The average UK mortgage rate has now surpassed 5%, a rise from 4.84% just a month prior. Lenders are actively adjusting their offerings, with many withdrawing deals or raising rates in response to ongoing global economic instability, particularly in light of tensions in the Middle East.
As a result, the overall cost for the 8.8 million mortgage holders in the UK, including capital repayments, reached £114 billion, translating to an average annual payment of £13,000 per borrower.
Rental Market Developments
In comparison, the rental market has seen a more gradual increase in costs, with spending up by 2.75% to £112 billion in 2025. A significant portion of this expenditure, approximately £81 billion, was directed towards private sector landlords, averaging £15,000 per tenant. Over the past five years, private renters have experienced a staggering 27% increase in their costs.
Interestingly, London has recorded the smallest percentage rise in overall housing expenses, at 36%. This is contrasted with more pronounced increases in other regions, such as the north-west (49%) and the north-east and eastern England (both at 45%). Despite this, London remains the epicentre of Britain’s housing costs, accounting for 23.4% of the total.
Price Trends and Market Stability
According to Rightmove, new seller asking prices have seen a seasonal increase, averaging £3,023 in March, bringing the typical asking price to £371,042. Despite the challenges posed by global uncertainties, the housing market has remained relatively steady, with sales only 2% behind last year’s robust performance and 5% above 2024 figures.
This suggests that, while the market is facing headwinds, it has not faltered significantly amid the ongoing geopolitical climate.
Why it Matters
The escalating costs associated with housing not only impact individual borrowers and renters but also have significant implications for the broader economy. As households allocate a greater portion of their budgets to housing expenses, their capacity to invest and spend in other areas diminishes. This trend could stifle economic growth and consumer confidence, particularly if inflation continues to rise due to external factors. The current situation underscores the urgent need for policymakers to address housing affordability and support measures for those most affected by these financial pressures.
