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.

Common Questions

Frequently Asked Questions About Boilers in Charlestown

01
How much does a new boiler cost?
A new gas combi boiler swap typically costs £1,800–£3,000 fully installed. System boilers with a hot water cylinder cost £2,500–£4,000. Prices vary by brand and complexity — moving the boiler location or upgrading pipework adds cost. We fit Worcester Bosch and Vaillant boilers with manufacturer warranties of up to 10–12 years when installed by an accredited installer.
02
How long does a boiler installation take?
A straightforward combi boiler swap typically takes 1 day. If we're moving the boiler location, converting from a system boiler to combi, or upgrading pipework, it may take 2–3 days. We always confirm the timeline during the initial survey so there are no surprises.
03
Should I repair or replace my boiler?
As a general rule, if your boiler is over 10 years old and needs a repair costing more than £400, replacement is usually more cost-effective. Modern boilers are 90%+ efficient compared to 60–80% for older models, meaning lower energy bills. We can advise on the most cost-effective option during a free assessment.
04
How often should a boiler be serviced?
A gas boiler should be serviced annually by a Gas Safe registered engineer. Annual servicing maintains your manufacturer warranty, ensures safe operation, identifies problems before they become expensive breakdowns, and keeps the boiler running at peak efficiency. Skipping a service can void your warranty and leaves safety checks undone.
