An analysis from the British Property Federation and Savills shows over 17,000 Build To Rent homes completed between Q1 2024 and Q1 2025.

This brings the total number of completed BtR homes to 127,150. 

This includes more than 55,400 homes completed in London and 71,700 across the regions, with regional growth (18%) outpacing the capital (13%).

Despite this strong delivery, the number of new starts has fallen behind, and for the fifth quarter in a row, completions have outstripped starts on site. This has led to a sharp 14% contraction in the number of homes under construction nationally. 

London has seen the steepest fall, down 18% year-on-year to just 15,000 homes under construction, while the regions dropped by 12% to 34,870.

Consented homes have risen 13% over the past 12 months and the total number of homes in planning, pre-consent, has grown by 5% to 109,920 units. However, detailed planning applications have fallen 16% since last quarter, raising concerns over longer-term supply.

The slowdown in construction reflects the broader challenges currently impacting housing delivery. 

Significant delays at the Building Safety Regulator are currently blocking schemes across the country, while concerns over development viability, driven by build cost inflation and the economic climate, are contributing to a cautious market. 

Taken together, these factors are slowing down delivery, as projects aren’t proceeding from outline planning through to detailed planning and ultimately into construction and delivery.

BtR continues to expand into new markets, with 215 local authorities now including BtR in their pipeline – up from 210 last year – with the Single Family BtR market playing a central role in this expansion, as 36,900 (13%) homes are currently under construction or in various stages of planning.

Melanie Leech, Chief Executive, British Property Federation, comments: “Completions remain robust, and planning activity is holding up well, but the sector is facing a real bottleneck in progressing schemes through to construction. 

“Viability challenges, coupled with continued uncertainty around project timelines are slowing momentum just at a time when rental demand is rising sharply. Investor appetite is there but unlocking it will require a concerted effort to support the delivery of BtR homes. 

“Urgent action is needed in particular to deal with the pipeline blockage currently being caused by the Building Safety Regulator. 

“The outlook for the remainder of the Parliament could be more positive, with specific support for Build-to-Rent expected as part of the Government’s long-term housing strategy. Tackling backlogs and delays at the Building Safety Regulator, combined with planning reforms starting to bed in, could help provide more certainty around delivery. 

“There’s no doubt that the sector’s ability to rapidly deliver high-quality, professionally managed homes will remain a vital part of the UK’s housing mix and the Government’s ambitious 1.5 million homes target.”
