About Rendesco
Rendesco designs, funds, drills, installs, owns and operates ground source heat networks, and has since 2012.

Rendesco started in 2012 with a simple idea: homes shouldn’t have to rely on fossil fuels for heating.
So we built the capability to deliver low-carbon heat ourselves: from drilling and engineering to installation, operation and maintenance.
That decision still defines us today: own what you build, and run it properly.
Fourteen years of doing it all ourselves is why we can price keenly, move quickly and stand behind the results for decades. It’s also why there are 12,000+ homes on our networks.
From the ground beneath the development to the heating in each home, we are dedicated to clean heating and cooling for the long term.
We started with a simple ambition: affordable, scalable clean heat for every home.
We demonstrated a different way to finance and deliver clean heating.
We showed the scale and reliability of our approach to low-carbon heating.
We raised funds to accelerate the transition to clean heating with our own network financing.
Most heat networks are delivered by several businesses, creating gaps between design, construction and long-term operation. At Rendesco, every stage sits within one accountable company. Because we operate what we build, every decision is made with long-term performance in mind.

“I am very pleased with Rendesco’s thorough and efficient service and repair. The engineer arrived exactly on time, was very helpful, diagnosed the problem quickly and returned within a few days to repair it successfully. A very expert and professional outfit at all levels.”
“Such is our confidence with Rendesco, we have recently instructed Rendesco to maintain our air source heat pump sites and conduct all water treatment and testing.”
“I have very much appreciated Rendesco's professionalism, their superior knowledge and their great manner when dealing with our residents. Excellent customer service all round.”
“I wasn't sure a heat pump would suit an older house, but Rendesco proved it. The heat pump and battery, optimised by Flow, cut our bills by 65% (£1,455 a year) and it just works.”
“Rendesco made the switch effortless. With an air source heat pump, battery storage and their Flow optimisation, we're saving 45% (£980 a year) and the house is consistently warm.”
“In the first month the Rendesco Flow system is on track to cut our energy bills by 40% and the house has been warm and comfortable at all times.”
