The UK build-to-rent sector recorded an 11.7% rise in completed homes over the past year, with cumulative completions climbing from 132,161 units in Q1 2025 to 147,670 in Q1 2026, according to new research from deposit alternative provider Zero Deposit.
The figures point to sustained expansion in a sector that has become a significant part of the UK's rental housing landscape. BTR developments are purpose-built for long-term renters and typically offer a higher standard of finish and service than much of the wider private rented sector, including professional building management, concierge services, dedicated amenity spaces, bundled services, enhanced energy efficiency and pet-friendly policies.
Rental premium continues to climb
Underpinning the sector's growth is its ability to command a consistent premium over the wider market. The build-to-rent rental premium reached 12.3% in 2025, nearly double the 6.5% recorded in 2016, reflecting growing tenant demand for purpose-built accommodation. The average monthly rent across the sector now stands at £1,546, compared with £1,377 across the wider private rented sector.
The gap is most pronounced in London, where build-to-rent properties average £2,560 per month against a wider market average of £2,280. Tenants' willingness to pay more reflects the amenities, professional management, energy efficiency and resident-focused services that many developments offer.
Investment remains strong
Higher achievable rents continue to attract substantial investor interest. The first quarter of 2026 saw £795.4 million invested into the sector, up 1.1% on the same period last year. This follows annual investment of £5.3 billion across 2025, itself 6.6% above 2024's total of £4.97 billion.
Protecting income in a changing market
As portfolios grow in both scale and value, protecting rental income is becoming an increasingly pressing concern for operators. Development costs are significant, rental values are high, and the impact of void periods or arrears is correspondingly greater. The Renters' Rights Act has added further pressure, limiting some traditional risk-management practices and accelerating interest in alternatives.
Insurance-backed guarantor products are attracting particular attention, especially given that many build-to-rent schemes draw international renters, overseas students and young professionals who may not meet traditional affordability checks or be able to provide a UK-based guarantor.
Touchstone, a build-to-rent operator, has adopted Guarantor+, Zero Deposit's regulated insurance-backed alternative to a traditional guarantor, designed for tenants who are financially capable of renting but lack access to a UK guarantor.
"The continued growth of the build-to-rent sector, alongside rising rental premiums, is reinforcing the importance of protecting rental income and maintaining operational efficiency across larger and more complex portfolios," said Harpreet Dosanjh, associate director and head of build-to-rent at Touchstone.
"As the sector expands, operators are also adapting to an evolving regulatory landscape shaped by the Renters' Rights Act, while continuing to serve a diverse customer base, including students, young professionals and international renters who may not have access to a traditional UK guarantor.
"In response, we selected Guarantor+ due to its straightforward claims process and three-year cover, which provides greater certainty than many alternative products offering shorter terms. This solution helps reduce barriers for prospective residents while supporting landlords in maintaining a broad and accessible customer base, particularly in student-heavy locations.
"Ultimately, we selected Guarantor+ because it provides peace of mind across the board, from a partner that understands the realities of the build-to-rent sector."
Sam Reynolds, CEO of Zero Deposit, said the results reflected both the quality operators deliver and the growing complexity of managing large rental portfolios. "The build-to-rent sector continues to go from strength to strength, with increasing levels of investment, growing stock numbers and consistently strong tenant demand. In addition, the ability to command a rental premium reflects the quality, service and experience that build-to-rent operators provide.
"As the sector expands, rental growth and assets under management continue to increase, making the protection of rental income more important than ever. Many operators serve tenant groups who may not have access to a traditional guarantor despite being financially capable renters. Guarantor+ bridges that gap, enabling operators to maintain strong occupancy levels while ensuring appropriate regulatory protection for both landlords and tenants.
"Our product is perfectly placed for a rental market that has faced significant disruption and change. We have the only solution that provides regulated protection for both tenants and landlords, an increasingly important consideration in the context of the Renters' Rights Era and the growing risks associated with it.
"We work with over 30% of the UK's BTR operators, and products like Guarantor+ are helping to provide greater long-term security, operational efficiency and compliance support across the sector. As adoption grows, these solutions are playing an increasing role in supporting the sector's long-term success."
