Changes to rental supply & demand in 2026
Nationally, the rental market is rebalancing. Zoopla reports that rental supply is up 15% year-on-year across the UK, while demand has fallen by roughly a fifth, driven in large part by a 78% decline in net migration between June 2023 and June 2025. This has eased the intense competition that characterised the post-pandemic market.
In Surrey, however, the picture is more nuanced. While some additional stock has entered the market as tenants have been able to purchase their first homes, demand in the county continues to outstrip supply, particularly for high-quality, well-located family homes. Towns like Guildford, with its university, strong employment base and excellent transport links to London, remain magnets for professional tenants.
The average house price in Guildford borough stood at £523,000 as of December 2025 (broadly flat year-on-year) which means affordability barriers keep many aspiring homeowners in the rental market for longer. For landlords, this translates into a deep, reliable tenant pool and properties that let quickly when properly managed.
Interest rates & mortgage costs in 2026
After several years of volatility, 2026 is expected to offer more stable borrowing costs for landlords.
Analysts predict the Bank of England will keep rates steady for most of the year, with reductions possible if inflation stays subdued. For landlords with variable or tracker mortgages, this is encouraging news. For those on fixed deals approaching expiry, the current environment offers far more palatable refinancing options than it did in 2022.
Rightmove’s forecast of 2% growth in average asking prices for 2026 suggests that capital values are also stabilising, offering landlords the prospect of steady total returns from both income and equity growth. At the same time, muted capital growth values are likely to tempt some homeowners to let their properties rather than choosing to sell up right now.
