Sigma Capital Brings Lettings and Property Management of London Multifamily Portfolio In-House Under Simple Life Management

Previously managed under a white-label arrangement with a third-party agent, the portfolio is now operated directly by Simple Life Management, setting a new gold standard for the London private rental market. Residents benefit from dedicated customer teams, a 24/7 maintenance portal, and fully furnished, pet-friendly homes, with apartments predominantly located in transport zones 3–6 and the final two sites currently under construction. 

Simple Life Management is underpinned by a bespoke operating platform designed to deliver excellence and efficiency at scale, directly enhancing net operating income (NOI) for the fund. Simple Life now has almost 6,000 homes directly under management across its owned portfolio and this first third-party contract. 

The Simple Life London portfolio marks Simple Life Management's first external full internalisation contract, a milestone that positions the platform to take on similar mandates from other institutional owners seeking an end-to-end operational partner. 

The expansion comes as former Ascend founder and long-time Sigma partner, Ged McPartlin, was appointed to the role of Managing Director of Simple Life Management in May 2026. Ged will lead the strategic growth of its national portfolio, further strengthening the platform’s position as one of the UK’s leading integrated build-to-rent operational platforms.  

Ged McPartlin, Managing Director of Simple Life Management, said: 

"Bringing the Simple Life London portfolio in-house reflects our long-term ambitions, with a strong offering across both single-family and multi-family housing. With a best-in-class operational model in place, our portfolio of homes, locations and services is scaling with real momentum. 

"Our partnership with EQT is a powerful endorsement of the Simple Life platform and the London opportunity. As institutional capital increasingly seeks exposure to UK residential, the demand for operators who can deliver excellence at scale has never been greater. Our integrated platform puts us in a strong position to capture that, driving the next stage of growth both for this portfolio and for institutional partners looking for an end-to-end operational partner. " 

Graham Barnet, CEO and Founder of Sigma Capital, said: 

"We have worked closely with EQT on our London portfolio through a turbulent period for the capital's construction market, and as the portfolio matures, we are collectively focused on identifying new areas of efficiency and value. London's build-to-rent supply is constrained, and with the well-documented shortage of housing across the city, demand for high-quality professionally managed homes will only continue to grow.  

"Bringing the lettings and management contract under our full Simple Life service will drive greater value for our investors while reducing costs. With Ged coming on board, this also marks our first externally managed contract under our in-house platform, alongside the 4,500 homes we manage on our own balance sheet."
