The housing market in the UK is experiencing a significant shift, with first-time buyers taking on record-high mortgages. The average first-time buyer now borrows a staggering £210,800, a figure that has been steadily increasing due to various factors. But here's where it gets controversial: is this a positive development, or are we heading towards a potential financial bubble?
First-time buyers are seizing the opportunity to purchase properties that were once out of their reach. Rising wages and more lenient affordability tests have created a perfect storm, allowing these buyers to take on larger loans. According to Savills, a leading property agent, first-time buyers accounted for a whopping 20% of all spending in the UK housing market over the past year, the highest level since 2007.
This trend is particularly evident in cities like London, where first-time buyers made up over half of all purchases this year, as per research by Hamptons, an estate agent. In total, mortgage lenders loaned a record £82.8 billion to 390,000 first-time buyers during this period, a 30% increase from the previous year.
But why are these mortgages getting bigger? Well, some first-time buyers are bypassing the traditional route of buying a flat and opting for houses instead. The average age of a first-time buyer is 34, and many have children by the time they enter the property market. Additionally, the stamp duty holiday, which allowed buyers to pay no tax on the first £425,000 of a property's value, encouraged many to purchase larger homes.
Lucian Cook, the head of residential research at Savills, attributes this record borrowing to a more relaxed approach by lenders. He states, "Home ownership is more accessible now than ever before due to lower borrowing costs, real house prices, and more accessible mortgage debt."
However, this relaxed lending environment has raised concerns. Mortgage lenders typically cap loans at 4.5 times a borrower's income and conduct stress tests to ensure borrowers can afford repayments if interest rates rise. But in March, the Financial Conduct Authority (FCA) warned that some lenders' stress testing methods were "unduly restricting access" to affordable mortgages. The FCA reminded lenders of their flexibility to design appropriate tests for their customers.
Since then, most lenders have lowered the interest rate at which they stress test borrowers, allowing first-time buyers to increase their borrowing by £20,000 to £40,000. This relaxation of lending rules coincides with easing mortgage rates, with average two-year and five-year fixes at their lowest since before Liz Truss's mini-budget in 2022.
According to Rightmove, house hunters can now typically snap up properties for about £2,000 less than a year ago and about £6,700 less than the average only a month ago. Across Britain, average asking prices in December 2025 are 0.6% (£2,059) lower than in late 2024, with the average asking price at £358,138, down 1.8% or £6,695 from November.
Annual growth in asking prices has varied across regions, with the strongest growth in the north-west of England (2.6%), flat in London (0%), and the most negative in the south-west and south-east (both at minus 2.7%). Rightmove expects a "Boxing Day bounce" as people who delayed their home-moving plans due to budget uncertainty start looking again after Christmas.
So, is this a sustainable trend, or are we heading towards a potential housing market crash? What do you think? Share your thoughts in the comments below!
