TSB and Barclays have joined a growing list of UK lenders raising mortgage rates, with TSB increasing fixed rates on all house purchase products by 0.15%. Barclays and other lenders including Skipton Intermediaries and Nottingham Building Society have also adjusted their pricing upwards. This latest wave of increases reflects ongoing cost pressures in the lending market and the Bank of England’s steady interest rate environment.
For property investors, these incremental rate rises mean borrowing costs are edging higher again after a period of relative stability. Even a 0.15% increase on fixed rates can translate into several hundred pounds more in annual mortgage payments on typical loan sizes. Investors relying on leverage should reassess cash flow models and stress-test their portfolios against further rate rises.
Data from Prop AI Deals shows that average fixed mortgage rates have climbed by around 0.3% since mid-2025. While this is not a sharp spike, the cumulative effect is enough to dampen yields in some areas, especially where rental growth remains subdued. Investors targeting buy-to-let properties may need to factor in tighter margins and potentially slower capital appreciation.
The broader message is that lenders remain cautious amid economic uncertainty, and mortgage pricing will likely stay firm or rise gradually. Investors should monitor lender pricing closely and consider locking in fixed rates sooner rather than later to avoid further cost escalation.
