Why Charlestown Homeowners Are Switching to Heat Pumps
Charlestown: 95% Off-Gas, Premium Properties, Specialist Installation
Charlestown is our most specialised heat pump market. With 95% of properties off the mains gas grid, virtually every home that wants to move away from oil heating will use the £7,500 BUS grant — and with average property values around £410,000, homeowners here are investing in premium systems. Daikin Altherma 3 and Mitsubishi Ecodan are our most common specifications in Charlestown, paired with Mixergy or Megaflo cylinders.
The Conservation Area Challenge
Charlestown is within the Cornwall and West Devon Mining Landscape UNESCO World Heritage Site buffer zone. External heat pump units visible from the harbour or street require planning consideration — we carry out this assessment during the free survey. In practice, most Charlestown properties have rear gardens or courtyards where units can be sited discreetly. The harbour area's character is preserved; modern heat technology is installed invisibly.
The 2-Mile Advantage
CCS Heating & Renewables is 2 miles from Charlestown — our closest coastal service location. For aftercare, warranty visits, and emergency response, that proximity matters. We have completed numerous installations in Charlestown and understand the specific planning, access, and noise considerations for the village.
Second Homes & Holiday Lets
A significant proportion of Charlestown properties are second homes. For these, we specify systems with remote monitoring so owners can manage heating from anywhere. Heat pumps are significantly simpler to manage remotely than oil boilers — no tank level to check, no delivery to arrange. See our holiday let energy guide.

Customer Reviews
What Our Customers Say
"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
"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.

"After much research we chose CCS for our heat pump installation and we are so glad we did. They took the time to explain everything, handled the grant paperwork, and the installation was completed in three days. Very professional team."
