How to translate growing investor appetite for SFH into supply

Single-family housing (SFH) has become an increasingly established part of the UK residential investment market. Investors are attracted by its relatively low-risk profile, typically high occupancy levels, and the breadth of its resident demographic.

With favourable market sentiment having solidified over the past few years, the investment case is no longer the most interesting question facing SFH. The challenge now is how we translate this growing investor appetite into a larger and more consistent supply of high-quality rental homes.

There is significant headroom to do so. In 2025, single-family build-to-rent housing accounted for less than 3 percent of houses listed for rent. By comparison, multi-family build-to-rent flats represented just over 20 percent of apartments listed for rent. For SFH to begin closing that gap, collaboration between institutional capital and the UK's housebuilders will be critical.

The evolution of the SFH market over recent years means that this collaboration is already well under way. Almost all national-scale housebuilders have now transacted a single-family sale. Barratt, Taylor Wimpey, Vistry, Persimmon, Bellway and Miller Homes are among those that have recognised how incorporating SFH into a mixed-tenure strategy can complement their core activities of selling homes and delivering affordable housing.

The market continues to mature, with a growing number of institutional investors actively transacting and establishing pipeline relationships with leading developers.

For the next stage of the market's development, these types of relationships will be vital. To deliver SFH at scale, we must focus on creating repeatable routes through which housebuilders can incorporate institutional rental into their development strategies and investors can secure appropriate stock.

There are some characteristics of SFH that make it particularly well suited to this kind of partnership. Schemes are usually further through the pre-development process when investors become involved, as major housebuilders are accustomed to managing the planning process themselves. This can give investors greater certainty and enable a quicker route to construction.

There can also be greater predictability around costs. Most housebuilders work with proven house types across their developments, adapting the mix for different tenures and target demographics. Standardised design and delivery therefore provide a high degree of cost predictability.

Finally, SFH lends itself to phased delivery. First homes can typically be handed over around six months into a development programme, with approximately four to eight homes delivered each month thereafter as homes are released progressively. This allows demand to be absorbed more gradually, without placing pressure on rental values, while helping to align investment returns with developers' pricing expectations.

These characteristics help explain why SFH can work for both sides of the partnership, giving housebuilders another route to market and institutional investors access to new housing supply.

Growing the market isn't simply about increasing the number of homes, however. The quality and suitability of that supply will be equally important. Developers have gained experience of what makes a successful SFH scheme, and the opportunities being brought to market are increasingly appropriate in terms of both scale and individual unit sizes. Homes are being considered as rental products rather than simply transferring larger properties designed for open-market sale into the rental sector.

Location selection continues to be driven by established demand fundamentals, including sizeable catchment populations, proximity to employment hubs, good schools and amenities, and well-developed transport infrastructure. A focus on these fundamentals allows the creation of homes offering investors sustainable rental demand and long-term performance.

There is still considerable room for the market to grow, and the opportunity is particularly apparent when we look at SFH supply levels. Allsop research suggests that more than 26,000 rental houses were sold in 2025 and did not subsequently return to the rental market, equivalent to roughly 8 percent of all houses listed for rent during the year. The equivalent net loss of rental apartments was just over 3 percent of the country's supply of rental flats.

Against that backdrop, the fact that SFH BTR represented less than 3 percent of houses listed for rent in 2025 highlights how much scope there is for the professionally managed sector to grow.

That does not mean SFH should expand at the expense of other housing tenures. The UK needs significantly more homes across the board. Housing delivery remains below the Government's target of 1.5 million homes over the five years to 2029, with macroeconomic and geopolitical uncertainty, planning constraints, construction costs, building safety requirements and buyer sentiment among the factors affecting delivery.

Therefore, room exists for home ownership, institutional private rental, social and affordable housing to grow alongside one another. For SFH, the ingredients for further expansion are increasingly solidifying, featuring strong institutional appetite, greater housebuilder experience, and a delivery model that can work for both parties.
