Design & Build
Heat pump and heat network projects delivered to your specification and build programme. Designed, drilled, installed and commissioned by one accountable specialist.


Most installers never meet their systems again. We’ve run the heat pumps and heat networks we build for more than a decade, so operational experience feeds every design decision: right-sized plant, serviceable layouts, monitoring built in from day one.

Geological and heat-yield risk sits with Rendesco. We assess the ground through desk studies and thermal response testing, design with appropriate margin to CP1, and drill using our own rigs. We apply the same approach across bespoke and funded networks, with the agreed risk position clearly set out in the contract.
Typically access, compound space, spoil arrangement and trench windows shared with your groundworks. This is itemised per project in the drilling attendances schedule.
Yes: we provide full D&B services to a performance spec, or build to a developed design with our drilling and installation scope defined around it. We confirm with clients where designs should be adjusted to ensure successful commissioning before contracting.
