Expert Boiler Installation in Charlestown
Boiler Installation & Replacement in Charlestown
With around 95% of Charlestown homes off the mains gas grid, most properties run on oil — so the practical questions here are oil-boiler servicing and replacement, and whether now is the time to switch heating systems. CCS is Gas Safe registered and works on oil, LPG and gas systems across the PL25 area, from the historic harbour cottages to the newer homes in Duporth.
Conservation-Area Flues and Oil-Tank Siting
Charlestown's conservation status and UNESCO World Heritage buffer zone control where external flue terminals and oil tanks can go on street- and harbour-facing elevations of listed and period buildings — something a standard boiler quote often overlooks. Every CCS survey checks flue routing, tank position and Listed Building Consent requirements before we commit to a design, so there are no planning surprises after installation.
The Off-Gas Upgrade: Oil Boiler to Heat Pump
For most Charlestown homes the strongest long-term move is replacing an ageing oil boiler with an air source heat pump — it carries the £7,500 Boiler Upgrade Scheme grant and pairs well with the village's south-facing solar aspect. We'll give you an honest comparison of a like-for-like oil replacement versus a heat pump on running cost, grant value and disruption. See our heat pump installation service for more.
