UK Build-to-Rent Market Kicks Off 2025 With Strong Investment Momentum

The UK’s Build-to-Rent (BTR) sector is showing no signs of slowing down in 2025, kicking off the year with more than £1.1 billion invested in the first quarter alone. This is the seventh straight year where Q1 investment has smashed the billion-pound mark, proof that notwithstanding economic worries elsewhere, the UK is a solid bet.

Although the numbers are a tad lower than the same period in 2024, they’re still in line with long-term averages. Knight Frank’s latest report shows that 18 property deals were completed in the first quarter of the year. The majority of those were in the Single Family Housing (SFH) sector, which made up half of all transactions.

This strong performance suggests the sector is likely to continue growing, especially since Knight Frank is already helping to manage another £1.7 billion worth of property deals expected to happen later in the year.

Investors Get Creative in a High-Cost Market

The way money’s flowing into BTR is evolving. Though funding new developments still dominates (making up 72% of deals), investors are also eyeing stabilised schemes (11% of transactions) as early backers look to cash out and recycle their capital. Meanwhile, joint ventures—now accounting for 17% of deals—are becoming a go-to strategy for spreading risk in an era of high construction and borrowing costs.

“With debt costs still elevated, investors are weighing up all options to get into the market,” notes Knight Frank’s report. One tactic gaining traction: forward commitments, where buyers lock in deals before construction even wraps up, but especially popular in the booming SFH segment.

Debt Markets Open Up, Just as Rate Cuts Loom

Some good news for investors: lenders are fighting to deploy capital, producing peak liquidity in the debt market. That competition is pushing margins down, making borrowing cheaper overall. Some banks are now providing 60% loan-to-value (LTV) ratios, in a sign of growing confidence in BTR’s stability.

Yet the bigger picture is still hazy. Fresh US tariffs and fear of slowing growth have markets betting the Bank of England could cut rates sooner than expected. If that happens, borrowing costs may dip further, possibly unlocking a fresh wave of investment.

Core Investors Are Back in the Game

Higher borrowing costs had kept some traditional core and core+ investors on the sidelines, but as conditions ease, they’re dipping their toes back in. A Knight Frank survey of 60 major UK Living Sector investors found 70% plan to ramp up core and core+ investments this year.

What’s catching their eye are Single Family Homes and low-rise multifamily projects, seen as safer bets in uncertain times. Looking ahead, investors rank SFH as the biggest growth area over the next five years, followed by co-living and traditional multifamily housing.

Fewer First-Time Buyers = More Renters for BTR

The reality is that homeownership is slipping further out of reach for many. Official data shows urban areas have seen the sharpest drop in first-time buyers over the last decade. In London every single borough recorded fewer new homeowners per 1,000 homes between 2013 and 2023. The same trend hit Manchester, Birmingham and Leeds hard.

That’s propping up rental demand as fierce competition push rents higher, a big tailwind for BTR developers catering to renters who can’t (or don’t want to) buy.

The UK now has 130,000 completed BTR homes; another 56,357 are under construction, and 108,757 have planning permission. But the pipeline is shrinking. Developers are contending with soaring costs, red tape and planning delays—only 28 projects are due for completion in 2027, suggesting a supply crunch could be looming.

“We’re seeing more SFH builds and fewer high-rise multifamily projects,” the report notes. Even though SFH construction jumped 29% year on year, multifamily starts tanked 20%.

Could Government Support Give the Sector a Boost?

The recent relaunch of the Private Rented Sector Guarantee Scheme—offering £2 billion in government-backed loans—could help unlock stalled projects. Knight Frank estimates the scheme could support 13,000 new BTR homes, about 12% of the current consented pipeline.

BTR Still Has Room to Run

Notwithstanding rapid growth, institutional investors still own only 2% of UK rental homes. The rest are held by small landlords. Knight Frank believes BTR could eventually make up 30% of the private rental market, translating to 1.9 million purpose-built rental homes.

And Single Family Housing could overtake multifamily due to surging suburban demand, with potential for over 1 million SFH units nationwide.

Conclusion

The UK’s BTR market is holding strong, but it’s not without hurdles. Investment is flowing, debt markets are competitive and policy support is expanding. Yet supply constraints could soon become a headache.
