In a significant shift for the UK housing sector, average private rents in Great Britain have halted their upward trajectory for the first time since 2017, according to comprehensive data released by the property website Rightmove. This stagnation follows nearly a decade of consistent increases, marking a pivotal moment in the rental landscape as landlords increasingly resort to price reductions to attract tenants.
Market Dynamics and Affordability Pressures
The typical advertised private rent outside London remained unchanged at £1,370 per calendar month during the first quarter of 2026. This flatlining represents the first instance since 2017 where rents have not climbed in the initial three months of the year compared to the preceding year's end. Rightmove emphasized that affordability remains severely stretched, with many tenants reaching the financial "ceiling" of what they can realistically pay.
Jeremy Leaf, a north London estate agent and former residential chair of the Royal Institution of Chartered Surveyors, noted that tenants have grown even more concerned about the escalating cost of living since the onset of the Iran war on 28 February. However, this geopolitical event has also spurred some relocation from the Middle East to the UK, bolstering demand in select segments of the premium rental market, as reported by the estate agency Chestertons.
Supply Increases and Landlord Adjustments
Rightmove's analysis reveals a notable 3% year-on-year rise in the number of available rental homes, with supply reaching its highest level for this period since 2021. Approximately 26% of rental listings are now undergoing price reductions while advertised—the highest proportion recorded since Rightmove began tracking this metric in 2012. Colleen Babcock, Rightmove's property expert, commented, "It's still early days, but the most immediate shift due to the war in Iran has been some significant increases to borrowing costs for landlords, which may filter through to the market at a later stage."
Landlords are now compelled to "position rents correctly for the current market," as lower tenant demand and a broader selection of properties alleviate the intense competition that previously drove rents upward. In London, the average advertised rent saw a modest 0.7% increase to £2,736 per month in the first quarter, though this figure remains below the peak recorded in summer 2025.
Regulatory Context and Market Stability
Rightmove reported "no major signs of changes" in rental market operations ahead of the Renters' Rights Act taking effect on 1 May 2026, which will eliminate section 21 of the Housing Act—a provision allowing landlords to evict tenants without court justification. Despite claims from charities about last-minute evictions preceding the law's implementation, Rightmove observed "no surge in newly listed homes for rent ahead of 1 May," indicating relative stability in this regard.
This evolving scenario underscores a broader recalibration in the rental sector, where increased supply and cautious tenant spending are reshaping landlord strategies and market expectations across Great Britain.
