"CCS installed our air source heat pump and the whole process was brilliant from start to finish. They handled the BUS grant application, and our heating bills have dropped significantly. The house is warmer than it ever was with our old oil boiler."
James & Sarah T.
St Austell — Air Source Heat Pump
"Had solar panels installed by CCS and could not be happier. Professional team, tidy work, and they explained everything clearly. Already generating more electricity than we expected, and the Smart Export Guarantee payments are a nice bonus."
David M.
Bodmin
"Our old boiler gave up in February and CCS had a new Worcester Bosch fitted within days. Excellent service, fair price, and the engineer was polite and thorough. Highly recommend to anyone in Truro and the surrounding area."

Truro · Boiler Installation
"We were nervous about switching from oil to a heat pump in our period cottage, but CCS made the whole process straightforward. The heat pump is quiet, efficient, and our oil delivery days are over. Brilliant job."
Mark & Louise R.
Fowey · Air Source Heat Pump
"Added a Foxstar battery to our existing solar panels. CCS fitted it in a single day and now we use almost all of our solar generation ourselves. The app monitoring is fantastic too — I can see exactly where every unit goes."

"Had underfloor heating installed as part of our extension and paired it with a heat pump. The combination works brilliantly — every room is a consistent, comfortable temperature. CCS designed the whole system and managed everything."

5 kW Solar Panels & Foxstar Battery, Newquay
A 14-panel solar PV system with a 9.5 kWh Foxstar battery installed in a south-facing semi in Newquay. Cornwall's above-average solar irradiance makes it an excellent location for solar, and the battery significantly increases self-consumption.
8 kW Vaillant Heat Pump with Underfloor Heating, Wadebridge
A complete heat pump and underfloor heating installation in a new build detached home in Wadebridge. The 8 kW Vaillant arotherm+ heat pump with whole-house UFH provides highly efficient, comfortable heating with running costs of under £600 per year.
