ONE SYSTEM.
Every part of your home.
Heat pump, solar, storage and control — engineered together, not bolted on.

Trustmark approved | MCS Certified | NAPIT accredited
Whole-home renewable energy, designed and installed across Gloucestershire and wider areas
PBT Installations are an MCS-certified, NAPIT-registered renewable energy company based in Cheltenham, serving homeowners, self-builders and businesses across Gloucestershire — Cheltenham, Gloucester, Stroud, Cirencester, the Cotswolds and the Forest of Dean.
We’re not single-trade installers. We design and fit heat pumps, solar PV, battery storage, air conditioning and smart energy controls as one integrated system, so each technology works with the others to cut your running costs and keep your home comfortable all year round. Whether you’re retrofitting an existing property or building from scratch, we’ll design a system around how you actually live.
Our technologies:
- Heat Pumps — exclusively premium Stiebel Eltron, for efficiency even in sub-zero temperatures
- Solar PV & Battery Storage — Solarwatt, and Tesla, designed to power your whole home
- Air Conditioning — cooling that can heat too, fitted by F-gas certified engineers
- Energy Management — smart controls that tie the whole system together
