Pioneer Point Partners , a private equity firm focused on sustainable infrastructure, has taken a majority stake in Rendesco.
The transaction represents the fifth investment by Pioneer鈥檚 second institutional fund, Pioneer Infrastructure Partners II, which reached final close in April 2025.
Pioneer has committed up to 拢100 million to Rendesco, with the Fund鈥檚 initial investment being used to acquire a majority stake in the business and support the delivery of its existing and future pipeline.
The commitment will facilitate up to 拢500m of capex investment in low-carbon heat network infrastructure, the firms say.
Founded in 2012, Cheltenham-based Rendesco is a leading UK heat network developer and operator, specialised in ground source heat pump solutions for new-build residential developments.
The company works with national and regional housebuilders to deliver low-carbon heating solutions for sites ranging from 50 to 2,000 homes and has installed heat networks at over 175 developments to date.
The recent publication of the UK鈥檚 Future Homes Standard provides clear regulatory support for low-carbon heating solutions in new residential developments.
Rendesco says its GSHP supplied heat networks offer high efficiency, low operating costs and the ability to provide both heating and cooling, making them an attractive solution for housebuilders and end customers.
Founder and CEO Alastair Murray (pictured) will continue to lead the business and remain a shareholder following completion.
