Sigma Capital Group is celebrating a decade of setting the standard for the BTR single family housing (SFH) industry, as it marks the milestone with over 12,500 homes completed or underway, across c.175 transactions.
Less than 12 months ago, Sigma took the strategic decision to internalise its lettings and property management with the introduction of ‘Simple Life Management Limited’ for Sigma’s balance sheet portfolio.
Over the course of the last decade, Sigma has achieved unrivalled operational scale across the UK, generating over £180m estimated rental value per annum, across all its portfolios.
The milestone comes as the UK’s single-family-housing sector is experiencing rapid growth. Last year, investors poured a record £1.9 billion into acquiring or funding homes, with SFH representing over 40% of all BTR investments for 2024, according to Knight Frank.
Sigma first pioneered UK single-family housing in 2014 and to date, has completed or contracted on over 9,600 SFH properties, with occupancy levels at 99% on all stabilised assets, and demand increasing year-on-year as awareness of the product grows – with over 30,000 enquiries for Simple Life properties in 2024 from the Simple Life website alone.
Over the last decade, Sigma’s product offering has grown, adapting to the needs of the market. In 2024, Sigma launched the first build-to-rent development to offer air source heat pumps in Mansfield, setting a new standard in gas-free heating. Tenants in Simple Life homes are also able to completely manage their tenancy independently, through the implementation of Simple Life’s app, which offers in-app messaging to make maintenance requests.
In 2024, Sigma also signed a new framework agreement with Vistry Group to deliver 5,000 new homes across the UK, as part of the longstanding collaboration with Countryside Partnerships.
2025 is set to be a transformational year for build-to-rent, as the Government continues to ramp up its housebuilding drive, aiming to build 1.5 million homes. According to the British Property Federation, two-thirds of local authorities in the UK are bringing build-to-rent forward as part of their housing delivery plans.
Sigma has a current pipeline of 19,000 units with a £5.9bn gross development cost and is expecting to reach 3,500 total units for its own balance sheet by the end of Q4 2025.
Graham Barnet, CEO and Founder of Sigma Capital: “In 2014, there wasn’t a typical professionalised rental product, and we’re proud to have shaped the BTR SFH sector over time."
"In the early days, the rental market was archaic, with an over-reliance on private landlords, and we had to bring together the investors, house builders, the land availability and local authorities to bring this product to market. Today, we have achieved significant scale across the UK as a result of our long-term relationships with partners in the public and private sector."
“Thanks to the tenacity of our team, we’re exactly where we wanted to be, with a superior product and unrivalled satisfaction scores. Our model is a best-in-class example of delivering high quality homes, and we’re looking forward to continuing to set the standard over the next decade and beyond.”
