Savills' latest Lettings Spotlight confirms what many landlords and letting agents have suspected for months: the era of double-digit rental inflation is over. UK rental growth slowed to an average of 3.2% in the year to Q2 2026, down from 5.8% a year earlier and a far cry from the 9-10% spikes recorded during 2022 and 2023. For an industry that has spent three years absorbing shockwaves from interest rate rises, tenant demand surges and acute stock shortages, this represents a meaningful inflection point rather than a temporary lull.
The significance for investors lies less in the headline number than in what sits beneath it. Savills' regional breakdown shows growth has become distinctly two-speed. Prime central London, long the bellwether for high-end rental demand, has seen growth flatten to just 1.1%, as returning corporate lets and a wave of new institutional build-to-rent completions in Nine Elms and Canary Wharf have finally given tenants some negotiating power. By contrast, regional cities are still recording robust uplifts: Manchester rents rose 5.4%, Birmingham 4.9%, and Leeds 4.6% over the same period, reflecting continued inward migration, expanding graduate retention, and comparatively constrained new supply relative to London's build-to-rent pipeline.
This divergence matters enormously for buy-to-let landlords weighing where to deploy capital. With mortgage rates having eased modestly from their 2023-24 peak — the average two-year fixed buy-to-let rate now sits around 5.1%, according to Savills' financing commentary, down from highs above 6.2% — regional cities offering both stronger rental growth and lower entry prices are increasingly favoured over London and the South East. Liverpool and Newcastle, both flagged in the report for yields above 6.5% gross, are attracting particular interest from portfolio landlords consolidating holdings outside the capital. Surrey and other commuter-belt markets, meanwhile, are seeing more modest 2.8% growth, as hybrid working patterns continue to soften demand for premium family lets within the traditional commuter radius.
The supply side of the equation is arguably more consequential than the demand figures themselves. Savills reports that available rental stock has increased by roughly 8% year-on-year nationally, the first meaningful expansion since 2019, driven by a combination of build-to-rent delivery — now running at over 25,000 new institutional-grade units annually — and a modest return of accidental landlords re-entering the market as mortgage affordability improves. This is the mechanism behind slowing rental inflation: it is not that tenant demand has collapsed, but that the chronic undersupply which characterised 2021-2023 is finally being addressed, albeit unevenly and overwhelmingly concentrated in major regional centres rather than London's inner boroughs.
For first-time buyers, this rental cooling carries indirect but real implications. Slower rent growth eases the affordability pressure that has kept many aspiring buyers trapped in tenancy for longer, potentially freeing up savings capacity precisely as mortgage rates stabilise. However, Savills cautions that this effect will be felt unevenly: in cities like Manchester and Birmingham, where rental growth remains elevated, the rent-versus-mortgage calculation still tilts firmly toward staying put rather than saving for a deposit, sustaining tenant demand even as landlords enjoy improving yields.
Looking ahead to the remainder of 2026 and into 2027, the direction of travel is reasonably clear. Savills forecasts national rental growth settling in the 3-4% range through the next 12 months, broadly in line with wage growth and a marked normalisation compared with the post-pandemic distortion. Institutional investment into build-to-rent is likely to accelerate further, particularly in Birmingham and Leeds where planning pipelines remain healthy and land values have not inflated as sharply as in London. The implementation of the Renters' Rights Act — with its restrictions on Section 21 evictions and tighter EPC requirements — will continue to squeeze smaller, less capitalised landlords out of the market, a trend Savills expects to further consolidate ownership among professional and institutional operators. For commercial investors and developers, this points toward one conclusion: the UK rental market's next phase of growth will be won not through speculative acquisition of existing stock, but through disciplined delivery of new supply in the regional cities where demand fundamentals remain structurally strong.
