Air Source Heat Pump Installation in Gorran Haven

Gorran Haven is 97% off the gas grid. Almost every property here runs on oil. With Dodman Point nature reserve to the east, the AONB to all sides, and only a single road in and out of the village, it's one of the most self-contained communities we serve — and the economics of switching from oil to a heat pump here are compelling.

Why oil dependency is particularly costly in Gorran Haven

Oil prices averaged 78p/litre in 2025–26. A typical 3-bed cottage in Gorran Haven burns 1,800–2,200 litres a year for heating and hot water — a £1,400–£1,700 annual fuel bill at current prices, up from under £900 in 2020. A heat pump with SCOP 3.2–3.5 in this mild coastal climate delivers the same heat for £700–£900 of electricity. Over 10 years, the saving commonly exceeds £6,000 — before the BUS grant.

Property types and what to expect

Pre-1900 harbour cottages — solid granite walls, original sash windows, 2–3 bedrooms. These benefit from heat pump retrofits but need careful assessment of existing radiator sizing. We often recommend adding one or two additional panel radiators in the living space at the same time — budget £600–£1,200 for this addition. Heat pump spec: 6–8kW, SCOP typically 2.9–3.3.

20th-century bungalows on the higher ground — mostly 1950s–70s construction. Straightforward cavity wall and loft insulation situation. Standard 6–8kW ASHP installation, existing radiators typically adequate. Best performance figures.

Rural farm properties in the surrounding area — larger buildings, higher heat loss. These may need 10–12kW heat pumps and a radiator upgrade plan. Good candidates for underfloor heating if extending or renovating.
