London Rents Cool as Required Salary Drops 17% to £71,550

New data from Propertymark shows the salary required to rent an average home in London has fallen by 17% year-on-year, from £86,250 to £71,550. For a capital that has spent much of the past three years as the byword for rental unaffordability, this is not a marginal adjustment — it is a structural signal that London's rental market is recalibrating after a period of extreme dislocation.

The scale of the shift matters because London has long set the tone for rental sentiment across the UK. When affordability deteriorates in the capital, it tends to be read as a leading indicator for other high-demand cities; when it improves, as it now has, investors and policymakers alike should ask whether this is a genuine turning point or a temporary correction. The most plausible explanation is a combination of factors: a modest easing in headline rents after two years of double-digit growth, wage growth finally catching up with housing costs, and a supply response as landlords who delayed selling during the stamp duty and mortgage rate turmoil of 2023–24 have brought stock back to market. Renewed supply, even at the margins, has real pricing power in a market as tight as London's.

For buy-to-let landlords, this data carries a nuanced message. Falling required salaries do not necessarily mean falling yields — in many cases they reflect rents plateauing after unsustainable growth, which is arguably healthier for portfolio longevity. Landlords in prime central London and inner boroughs such as Hackney, Islington and Wandsworth, where rent-to-income ratios had become genuinely stretched, may see slower rental growth but more stable tenancies and reduced void periods. Landlords who overpaid for stock in 2022–23 anticipating continued rent inflation will need to reassess yield assumptions, particularly with mortgage rates still elevated relative to the ultra-low rate era.

The regional context is instructive. Manchester and Leeds have seen rental growth of 6–8% over the past year, according to recent lettings agency data, still comfortably outpacing London's cooling trajectory. Birmingham, buoyed by HS2-adjacent development and institutional build-to-rent investment, continues to post tighter voids and firmer rent rises than the capital. Liverpool and Newcastle, both benefiting from relative affordability and strong rental yields of 6%-plus, remain attractive to yield-focused investors precisely because they have not experienced the same affordability ceiling now constraining London. Surrey's commuter belt, meanwhile, occupies a different position again — hybrid working patterns have sustained demand for family rental homes even as core London demand softens, meaning affordability pressures there have not eased at anything like the same pace.

For first-time buyers and renters aspiring to homeownership, an easing in required rental salary offers modest breathing room to save for deposits, but it should not be mistaken for a broader affordability fix. London house prices remain roughly 12 times average earnings in many boroughs, and a 17% fall in the rental salary threshold does little to shift the fundamental deposit hurdle. What it does do is reduce the immediate cost-of-living pressure that has driven tenants to double up, move further out, or delay household formation altogether — a trend that has itself been distorting demand data across the South East.

Looking ahead six to twelve months, expect London's rental market to settle into a more moderate growth pattern of 2–4% annually rather than the 8–10% spikes seen in 2022 and 2023, assuming the Bank of England holds or gradually eases rates and net migration into the capital stabilises. Institutional investors and build-to-rent developers should read this as confirmation that London yields will compress further relative to regional cities, reinforcing the current capital flow toward Manchester, Birmingham and Leeds, where rental growth and yield profiles remain more compelling. Commercial investors weighing PRS and BTR acquisitions should treat this data as a signal to diversify regional exposure rather than assume London's affordability correction reverses the broader northward shift of rental investment capital.

The direction of travel is clear: London is no longer the runaway outlier it was two years ago, but this is a rebalancing, not a collapse. Investors who treat the 17% fall as evidence of a softening capital market, rather than a return to genuine affordability, will price their strategies more accurately over the next year.
