The squeeze on mortgage affordability for homebuyers across the United Kingdom has reached its most severe point since the financial crisis of 2008, according to new data released by the banking industry body UK Finance.
Last year, typical homebuyers across the nation allocated just over one-fifth (21.3%) of their gross income towards mortgage payments, marking the highest proportion recorded since 2008. This figure underscores the mounting financial pressure on those striving to get onto the property ladder or move home.
Regional Disparities in Affordability
The burden of rising mortgage costs is not uniformly distributed, with certain areas experiencing far greater strain. In North Norfolk, located in East Anglia, and the London borough of Hillingdon, new borrowers typically spent more than a quarter of their gross income on mortgage repayments.
According to UK Finance, the least affordable local authority in 2025 was North Norfolk, where homebuyers needed 25.7% of their gross income to cover initial mortgage payments. Other areas facing acute affordability challenges include several London commuter belt locations such as Luton (24.9%), Slough (24.8%), and Spelthorne (24.8%).
Conversely, the most affordable local authorities were predominantly found in Scotland, with East Ayrshire and Inverclyde topping the list. Interestingly, the City of London, despite being a major business district with limited residential stock, ranked as relatively affordable due to its high-earning buyer profile.
Market Activity and Economic Context
UK Finance reported that 723,000 house purchase mortgages were issued in 2025, representing a 17% increase compared to the previous year. However, this uptick in activity occurred against a backdrop of elevated mortgage rates, which had surged earlier in the year amid market uncertainty linked to the conflict in the Middle East. Although rates have eased somewhat in recent weeks, they remain high by historical standards.
James Tatch, head of analytics at UK Finance, commented: "It has been challenging times for those trying to buy a property in recent years, with affordability pressures weighing heavy. But the pain is not felt equally across the country. Property prices, wages, and demographics vary greatly across and within regions. All of these have an impact on affordability and, if you are a landlord, how profitable your investment property is."
Tatch added that understanding local market nuances enables better decision-making for government and local authorities, and that UK Finance looks forward to continuing work with stakeholders to improve the mortgage market.
Industry Perspectives on Affordability
Mary-Lou Press, president of NAEA Propertymark, highlighted that higher interest rates and the challenge of saving for a deposit mean many people who could afford monthly repayments are still locked out of buying. "It is no longer just about income; access to upfront cash is becoming the biggest barrier," she said. Press also noted clear regional differences, with buyers in more affordable parts of the UK remaining active, while in higher-value areas such as London and the South East, stretched affordability is slowing activity and forcing buyers to adjust expectations.
Aneisha Beveridge, head of research at Hamptons, observed that homeowners in London's commuter belt are among those feeling the impact of higher mortgage rates most sharply. "These are areas where a much larger share of households rely on a mortgage, especially compared to central London. It is also where first-time buyers and upsizers are stretching the hardest to get a bit more space, often pushing loan-to-income multiples to make the numbers work," she said.
Beveridge added a note of perspective: "For many renters, spending this proportion of income on housing would feel like a step forward. Even with rates edging up again over the last month, owning with a mortgage is still often cheaper than renting, so affordability challenges are increasingly about access and upfront barriers, rather than just the cost of monthly repayments."
