Why Charlestown Homeowners Are Switching to Heat Pumps

Charlestown is one of the towns covered by our county service — see heat pump installation in Cornwall for costs, standards and the full picture.

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 up-to-£9,000 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.

Common Questions

Frequently Asked Questions About Heat Pumps in Charlestown

01
How much does it cost to fit a ground source heat pump in Cornwall?
A complete ground source installation in Cornwall is typically £18,000-£32,000 before grants: £11,500-£16,800 for the heat pump, cylinder, controls and commissioning, plus £6,000-£14,000 for trenched or slinky ground loops or £12,000-£22,000 for vertical boreholes. The Boiler Upgrade Scheme takes £7,500 off, or £9,000 until March 2027 if you are replacing oil or LPG and have no mains gas connection, and installations in homes are zero-rated for VAT until 31 March 2027.
02
What are the downsides of a ground source heat pump?
Two, mainly: cost and disruption. The ground array is most of the extra money over an air source system, and it means either trenching roughly 2.5 times your heated floor area or drilling boreholes. On a small garden the trench option disappears and drilling is the only route. Against that, the heat pump sits indoors with no outdoor unit, seasonal efficiency is typically 4.0-4.8 against 3.0-3.5 for air source, and the buried loop long outlives the heat pump itself.
03
How much land do you need for a ground source heat pump?
For horizontal collectors, roughly 2.5 times the heated floor area of the house, trenched at about 1.2-1.5 m deep — so a 150 m² house needs something like 375 m² of diggable ground. Slinky coils fit the same collector length into shorter trenches. Where there is no land, vertical boreholes of typically 90-150 m each replace the trenches and take a fraction of the surface area.
04
Is ground source better than air source in Cornwall?
It is more efficient and more expensive. Ground temperatures here stay around 9-12°C all year, so a ground source system runs at a seasonal efficiency of about 4.0-4.8 against 3.0-3.5 for air source, with no outdoor unit and no noise assessment. Air source costs roughly half as much to install and fits any property. Since the Boiler Upgrade Scheme now pays the same for both, the decision comes down to available land, disruption and how long you will own the house.
05
Do I need planning permission for a heat pump in Cornwall?
Air source heat pumps on houses are permitted development under Class G of Part 14 of the GPDO as amended on 29 May 2025 — one unit on a terraced or semi-detached house, two on a detached house, up to 1.5 cubic metres, meeting the MCS 020 a) standard including a 37.0 dB(A) limit at a neighbour's window. In a conservation area or the Cornwall and West Devon Mining Landscape World Heritage Site the unit cannot go on a wall or roof fronting a highway, or nearer a highway than the house. Listed buildings need permission. Ground source heat pumps have no Part 14 limits.
