High-Risk UK Mortgages Climb to 46% as Affordability Crisis Deepens

Nearly half of all gross mortgage advances in the UK during the second quarter of 2026 were issued to borrowers at high loan-to-income ratios, according to new figures from the FCA and Bank of England. The 46% share marks a sharp increase from 41.4% a year earlier.

Jinesh Vohra, chief executive and co-founder of mortgage overpayment platform Sprive, called the trend a structural problem the industry is failing to address. Speaking on Twenty7tec's ELEVATE Podcast Series with host Ellisha Jade, Vohra argued that lenders and brokers focus too heavily on monthly affordability while neglecting the lifetime cost of debt.

I think it's very important that people understand the cost of debt, because it's not just about meeting the monthly payments. You have to be able to do that over the entire lifetime of the mortgage.

The affordability squeeze has driven a growing share of first-time buyers toward mortgage terms of 30 or 40 years. Stretching the repayment period lowers the monthly payment and helps more applicants pass lender affordability checks, but it significantly raises the total interest paid and leaves borrowers carrying substantial debt later into their careers — and in some cases, into retirement.

Research from Yorkshire Building Society found that 56% of prospective first-time buyers still consider mortgage acceptance difficult, suggesting the underlying affordability constraint remains unresolved despite the structural workarounds now in widespread use.

The pattern is compounded by intermittent customer engagement. Twenty7tec's August 2026 Mortgage Market Snapshot recorded 616,150 remortgage searches, an 11% year-on-year increase. While that activity shows borrowers actively reviewing their arrangements, Vohra argued that two-to-five-year remortgage cycles are insufficient to provide the ongoing financial support homeowners need.

If you are interacting with that customer every two to five years, when they're effectively looking to refinance, how strong is that relationship?

The rising share of high loan-to-income lending is not new to regulators. The Bank of England's Financial Policy Committee has maintained a flow limit on high loan-to-income mortgage lending since 2014, capping at 15% the proportion of new lending at or above 4.5 times income for any given lender.

The Q2 2026 data point of 46% refers to the broader high loan-to-income bracket, not solely those at or above 4.5 times, but the directional trend has attracted regulatory attention as affordability pressure intensifies. Any significant deterioration in borrower resilience at extended terms could prompt the FCA or PRA to revisit the adequacy of affordability stress tests.

Sprive's own position is that technology and data can support more continuous borrower engagement outside of transaction moments. The platform allows homeowners to direct spending rewards toward mortgage overpayments and provides modelling tools on the impact of early repayment.

Vohra's Series A, a $10 million round announced in September 2026 and bringing total funding to more than $15 million, is earmarked for customer acquisition and revenue growth in the UK market. The commercial thesis rests on sustained customer relationships rather than point-in-time origination, which aligns the product with the structural critique Vohra is making of the wider industry.

For mortgage technology providers and lenders, the debate points to a growing commercial opportunity in post-origination engagement tools, an area where the industry's existing technology stack, built largely around sourcing and application processing, remains relatively thin.
