Air Source Heat Pump Installation in Falmouth

Heat Pumps in Falmouth: Premium Market, Strong Adoption

Falmouth is Cornwall's largest deep-water harbour town and one of the most environmentally engaged communities in the South West. With around 22,500 residents, Falmouth University, and a substantial premium coastal housing market at Pendennis, Gyllyngvase, and Maenporth, the demand for high-specification air source heat pump installations here is consistently strong. CCS Heating & Renewables installs heat pumps across TR11 from our Pool office — a 25-minute drive away.

Where Heat Pumps Make the Strongest Case in Falmouth

• Pendennis & Gyllyngvase premium homes: High-value detached and semi-detached properties, often oil-heated (private estate roads frequently off mains gas). 12–16kW Daikin Altherma or Mitsubishi Ecodan systems with 250–300L unvented cylinders typical. Net cost after the £7,500 BUS grant: £8,000–£14,000, or £6,500–£12,500 with the £9,000 off-gas uplift.
• Maenporth & Mawnan Smith: Off-grid coastal properties — heat pump replaces oil entirely, saving £800–£1,500/year in fuel. See our oil to heat pump guide.
• Boslowick & Trescobeas estates: Inter-war and post-war semis with cavity walls — among the smoothest retrofits we do. 8–10kW units typical, minimal radiator upgrades.
• The Moor & Killigrew Victorian terraces: Solid stone/brick construction. 9–11kW units with 2–4 radiator upgrades. Conservation area considerations apply for outdoor unit positioning.
• Listed Georgian high town properties (Arwenack Street, Church Street): Specialised heat-loss design and listed building consent required. CCS handles the application.

The University & Maritime Influence

Falmouth University at Penryn is a major sustainability-focused institution, and its environmental research community is a visible local advocate for heat pumps and renewable energy. The Pendennis Shipyard, one of the UK's leading superyacht builders, has its own decarbonisation programme. This creates a culture in Falmouth that is exceptionally favourable to heat pump adoption.

Costs After the BUS Grant

Typical net costs in Falmouth after deducting the £7,500 Boiler Upgrade Scheme grant (£1,500 less again where the £9,000 off-gas oil/LPG uplift applies): £4,500–£6,500 for a small Moor terrace; £6,000–£8,500 for a Boslowick semi; £8,000–£14,000 for a Pendennis or Gyllyngvase premium detached. Running costs versus gas are roughly comparable when COP averages 3.5+ across the year. Versus oil — the situation in Maenporth and Mawnan Smith — savings are £800–£1,500/year.

Listed Building & Conservation Area Process

CCS Heating & Renewables prepares listed building consent applications and conservation area consent applications as part of the project for the listed Georgian properties on Arwenack Street, Church Street, and within the wider Falmouth conservation area. We position outdoor units sympathetically — typically rear courtyards or side returns where they are not visible from the street.

Pair with Solar & Battery

Combining a heat pump with solar PV and battery storage in Falmouth — particularly on the south-facing Pendennis cliff-tops — creates an exceptionally strong financial case. A 6kWp solar + 13.5kWh battery + 12kW heat pump system can reduce annual energy bills to under £400. See our combined solar and heat pump guide.
