More than 834,000 rental properties have left the traditional private rented sector over the past decade, while institutional Build to Rent supply continues to expand, according to new analysis from TwentyCi.

The company’s Q2 2026 Property & Homemover Report estimates that 834,800 properties have exited the traditional PRS over the period.

At the same time, Build to Rent listings increased by 22% during the second quarter, highlighting the changing composition of rental housing supply.

However, new rental supply during the year to date was 17.4% higher than during the equivalent period of 2025, while June 2026 recorded the first annual increase in available rental stock for five years.

The wider residential sales market presented a mixed picture during the second quarter.

New property listings were 0.5% higher than a year earlier, while the number of sales agreed fell by 5.8%. Exchanges, however, increased by 2.8%, while fall-throughs were 8.7% lower.

Newly listed properties were priced an average of 11.6% above their automated valuation model value, compared with a gap of 5.7% a year earlier.

The findings suggest that while rental supply may be beginning to improve, the structure of the sector continues to change, with traditional landlord-owned properties declining over the longer term as institutional Build to Rent becomes a larger part of the market.
