UK build-to-rent investment has reached an all-time high of £3 billion during the first half of 2026, despite concerns over the sector's ability to meet surging demand. The substantial figure represents a significant 28% increase on the same period last year and marks the second-strongest start to a year on record for the burgeoning housing segment.
A whopping £2 billion was driven by three major portfolio transactions in the second quarter, including L&Q's extensive 3,200-home Metra Living portfolio, Lendlease's Elephant Park development in London, and Blackstone's sale of approximately 1,000 single-family homes from its Leaf Living business. These large-scale deals helped to recover from a more subdued first quarter, which saw just £736 million invested.
However, beneath the headline figures lies a concerning trend: funding for new multifamily development has plummeted to its lowest level since at least 2015. Investment through forward funding, forward purchases, and land acquisitions accounted for a mere 10% of multifamily investment during the first half of the year – a stark contrast to the period between 2023 and 2025 when such development funding typically represented around two-thirds of total investment.
Karl Tomusk, an associate in UK living research at JLL, described the dearth of investment in new multifamily homes as 'staggering', highlighting the challenge of making new developments financially viable despite recent improvements in mortgage rates. The current scenario underscores a clear dichotomy: strong investor demand for existing operational BTR properties, but significant difficulties for developers in bringing new schemes to fruition amidst the prevailing economic climate.
The long-term implications could be a widening gap between housing supply and demand in a sector already described as 'fundamentally undersupplied'. While a recovery in development activity is anticipated should market conditions improve, the immediate outlook points to continued challenges in expanding the UK's rental housing stock.
