Sentinel Real Estate has acquired UK affordable housing manager Hearthstone Investments to scale its recently launched UK living platform.

Founded in 2009, Hearthstone manages a portfolio of over 1,800 affordable rental homes across England, Scotland and Wales, representing more than £400m (€468m) in assets under management on behalf of institutional investors, including UK local government pension schemes.

The acquisition follows Sentinel’s formal entry into the UK market in January 2026.

Under the terms of the deal, the Hearthstone team will be integrated into Sentinel’s global platform.

Michael Streicker, president and CEO of Sentinel, said: “Expanding to the UK represented a logical evolution of the platform that we have successfully built across the US and Australia. This corporate acquisition provides us with highly complementary business in the attractive UK living sector.

“The team at Hearthstone has a proven track record of raising, managing and deploying capital at scale in this sector, and we look forward to working collaboratively with them to grow our UK business.”

Ben Sanderson, managing director at Sentinel in the UK, said: “We believe strongly in UK rental housing and were prepared to build our business organically. However, we were attracted by the opportunity to accelerate our growth in the market through the acquisition of a professional, experienced team with a sizeable portfolio.

“This acquisition will provide a strong foundation for delivering value to our clients and capitalising on the significant investment opportunities we have identified across the UK living sector.”

Cedric Bucher of Hearthstone said: “We are delighted to be joining Sentinel, a firm with deep residential expertise, global resources and a long-term investment focus. Together, we can build on the Hearthstone team’s achievements while scaling Sentinel’s platform, enhancing its capabilities and accelerating the next phase of growth in the UK market.”
