Rent Hikes Loom as Buy-to-Let Mortgage Costs Surge by £1,100 Annually
Experts are issuing stark warnings that rental prices are set to skyrocket as buy-to-let mortgage repayment costs increase by an average of £1,100 per year. This financial pressure on landlords is compounded by upcoming regulatory changes, creating a perfect storm in the private rental sector.
Soaring Mortgage Rates and Shrinking Product Choice
According to the latest research from Moneyfactscompare.co.uk, buy-to-let fixed mortgage rates have risen sharply since the start of March 2026, largely due to unrest in the Middle East. The two-year fixed rate has reached 5.40%, its highest level in a year, while the five-year fixed rate stands at 5.91%, a two-year peak.
For landlords with a £250,000 loan over a 25-year term, borrowing costs for a two-year fixed deal are now £1,100 higher compared to early March. Additionally, the overall choice of buy-to-let mortgage products has plummeted by around 1,300 deals since March began, with availability dropping below 5,000 for the first time since November 2025.
Regulatory Pressures and Landlord Challenges
Landlords are also bracing for the Renters’ Rights Act, which comes into force in May 2026. This legislation will require property owners to invest up to £10,000 to achieve an Energy Performance Certificate (EPC) rating of C by October 2030. These combined financial and regulatory burdens are pushing many landlords, particularly smaller investors, to reconsider their positions in the market.
Rachel Springall, Finance Expert at Moneyfactscompare.co.uk, commented: “Soaring borrowing costs will cause pain to landlords this year, as they join millions of consumers facing higher mortgage repayments. This is terrible news, as rising costs could lead to higher rental payments for tenants, or a drop in the pool of properties available for rent if landlords decide enough is enough and sell off their portfolio.”
Industry Insights and Market Shifts
Zaman Sheikh, Director of Northwood Chelmsford, highlighted the severe impact on smaller landlords: “Smaller landlords are currently facing a perfect storm of increased regulatory and borrowing costs. For many, higher mortgage rates have acted as the final straw and they are choosing to exit the sector altogether.”
Sheikh noted that buy-to-let investments have become increasingly challenging, with mortgage rate hikes turning an uphill slog into an Everest. Landlords are now intensely focused on Return on Investment (ROI) and yields, leading to a trend of London landlords selling properties due to low yields and shifting investments to areas outside the capital where returns remain more reasonable.
He added: “Tenants are clearly also vulnerable as, in many cases, landlords will have no choice but to pass on the cost of higher mortgage rates. It’s a challenging time right now.”
The combination of geopolitical instability affecting mortgage rates and stringent new regulations is reshaping the rental landscape, with significant implications for both landlords and tenants across the UK.
