UK Homebuyers Confront Highest Mortgage Affordability Pressures in Nearly 20 Years
UK homebuyers are experiencing the most severe mortgage affordability challenges in almost two decades, though the impact varies significantly across different regions, according to data from UK Finance.
The banking organization reported that, on a national scale, initial mortgage repayments typically consume more than one-fifth (21.3%) of a homebuyer’s gross income, marking the highest level since 2008.
This data pertains to 2025 and does not yet reflect the economic disruptions caused by the Iran war, which has contributed to increased mortgage costs. As a result, many mortgage applicants now face paying hundreds or even thousands of pounds more than prior to the conflict.
Regional Variations Highlighted in Mortgage Affordability
UK Finance emphasized that the headline figure conceals notable regional disparities.
The "least affordable" locations, measured by mortgage repayments as a percentage of income, include north Norfolk and the west London borough of Hillingdon. In these areas, homebuyers typically allocate over a quarter of their gross income to mortgage repayments (25.7% and 25.1%, respectively).
Eight of the remaining ten least affordable areas are situated within the London commuter belt. Examples include Luton in Bedfordshire (24.9%), Slough in Berkshire (24.8%), Broxbourne in Hertfordshire (24.4%), and Harlow in Essex (24.2%).
Conversely, seven of the ten most affordable local authority areas are located in Scotland. Leading this list are East Ayrshire and Inverclyde, where the average homebuyer in 2025 commits 17% of their gross income to initial mortgage repayments.
Some may find it surprising that the City of London ranks as the third most affordable local authority for home ownership. UK Finance explained this is because buyers able to afford homes in the City typically belong to the highest-earning income brackets.
Although the City is dominated by financial services firms and includes the 2,000 flats of the Barbican estate, it remains one of the UK’s most expensive housing markets.
UK Finance described this as a "quirk" of their analysis, noting that the City of London appears as affordable on this metric as some Scottish areas where property prices are considerably lower.
Expert Commentary on Affordability Challenges
James Tatch, head of analytics at UK Finance, said the past few years had been challenging for those trying to buy a property, with affordability pressures weighing heavy.
“But the pain is not felt equally across the country,” he added. “Property prices, wages and demographics vary greatly across and within regions. All of these have an impact on affordability.”
Mortgage Market Activity Amid Affordability Pressures
Despite ongoing affordability challenges driven by high property prices, borrowing costs, and the difficulty of saving for deposits, 2025 saw "robust activity" in house purchase borrowing, according to UK Finance.
The number of mortgages granted by banks and other lenders for house purchases reached 723,000, representing a 17% increase compared to 2024.
UK borrowers had been benefiting from lower-cost home loans until the outbreak of the war on 28 February, which caused a surge in fixed-rate mortgage deals. However, recent weeks have witnessed a gradual decline in fixed-rate mortgage pricing.
