Heat Pumps in the Roseland & East Cornwall: Rural Off-Grid Homes 2026
Cornwall's Roseland peninsula and the rural East Cornwall hinterland share a common characteristic: historic villages with little or no mains gas, where oil heating has persisted for decades and the £7,500 BUS grant now makes the switch to a heat pump highly compelling.
The Roseland Peninsula: AONB, Off-Grid, Oil-Dependent
The Roseland Peninsula — the headland between the Fal estuary and Mevagissey Bay — is one of the most beautiful and isolated parts of Cornwall. Designated an Area of Outstanding Natural Beauty, with narrow lanes, scattered farmsteads, and villages like Veryan, Portloe, and Gerrans clinging to hillsides above the sea, the Roseland is almost entirely off the mains gas grid. Oil lorries are a regular sight on the narrow roads between villages here.
The same characteristics apply across much of rural East Cornwall — villages like Lanivet, Lanreath, St Neot, Dobwalls, and Pelynt share the Roseland's off-grid dependence on oil and LPG, with the added context of sitting in the Fowey Valley, Bodmin Moor fringe, and South East Cornwall countryside. For homeowners in all these areas, the £7,500 Boiler Upgrade Scheme grant — available for every oil-heated household — represents the most significant opportunity to reduce long-term energy costs.
CCS Heating & Renewables installs heat pumps across the Roseland and East Cornwall, reaching villages via the A390 and B-road network. Our surveyors are familiar with the planning sensitivities and property types these areas present.
Veryan and Tregony
Veryan is one of Cornwall's most photogenic villages — famous for five extraordinary Grade I-listed Round Houses at its entrance, built to prevent the Devil sheltering in corners. The village has a strong conservation area designation, but air source heat pump outdoor units are permitted development and we have installed heat pumps in similarly heritage-sensitive Cornish villages throughout our service area. At around 95% off-gas, virtually every Veryan homeowner qualifies for the BUS grant.
Tregony sits at the gateway to the Roseland, where the B3287 crosses the upper Fal River. Once a medieval stannary town, Tregony retains considerable period character — granite and slate buildings along its main street, a conservation area, and almost complete absence from the gas grid. The combination of period properties and 90%+ off-gas makes it a natural heat pump market. Our guide to heat pumps in older properties is directly relevant for Tregony homeowners.
Probus and Grampound
Probus is known throughout Cornwall for the tallest church tower in the county — the 15th-century tower of St Probus and St Grace, rising 123 feet above the village. The surrounding community is a mix of Victorian housing, post-war residential estates, and rural properties — with an off-gas rate of around 80%. Probus sits on the A390, giving good road access, and the village's proximity to Truro (6 miles) means a proportion of its residents are professional-demographic commuters with the income profile to self-fund premium heat pump installations.
Grampound (not to be confused with Grampound Road) is a small village on the A390 with a medieval market town history — and off-gas rates that exceed 85%. Both villages are within easy reach of our service area and both qualify for the full BUS grant.
East Cornwall Rural Villages
Lanivet
Lanivet sits at the geographical centre of Cornwall on the Saints' Way — the ancient pilgrimage route from Padstow to Fowey. Stone-built rural cottages, inter-war semis, and farmhouses dominate the housing stock. All are off-gas. The BUS grant applies and we can reach Lanivet efficiently via the B3268 from our base.
Lanreath
Lanreath is a dispersed rural community in the South East Cornwall countryside, set in rolling farmland between Lostwithiel and the coast. Its scattered farmsteads and rural properties are almost entirely oil-heated — the settlement is too dispersed for a gas grid to have ever reached it economically. For Lanreath homeowners, a heat pump with the BUS grant represents a permanent solution to oil price volatility.
St Neot
St Neot is one of the most remarkable villages in Cornwall, known for its 15th-century stained glass windows — one of the finest collections of medieval glass in Britain. The village sits on the edge of Bodmin Moor at around 200 metres elevation, giving it colder winter conditions than coastal Cornwall. Heat pumps still perform effectively here — Bodmin Moor's winter temperatures rarely drop below -3°C and a correctly specified system with a 10–15% capacity buffer handles cold snaps comfortably.
Dobwalls and Pelynt
Dobwalls is a village on the A38 between Liskeard and Bodmin — a practical, road-junction community with a mix of property types from former clay workers' housing to modern residential development. Off-gas rates are high, and the BUS grant is applicable to the majority of properties.
Pelynt is a South East Cornwall village in the Looe Valley hinterland — a historic settlement with a medieval church and predominantly off-gas housing. Many Pelynt homeowners heat with oil in properties that are well suited to heat pump conversion.
AONB and Planning: What It Means for Heat Pumps
Much of the Roseland and parts of East Cornwall fall within the Cornwall Area of Outstanding Natural Beauty. A common concern is whether AONB status prevents or restricts heat pump installation. The answer is: generally no. Air source heat pump outdoor units are permitted development in England under permitted development rights (Part 14 of the GPDO), and the AONB designation does not remove these rights for permitted development.
The exceptions are:
- Listed buildings — require full planning permission for any external installation
- Units visible from the principal elevation and facing a highway in a conservation area — may require prior approval
- Units on a wall or roof forming the principal elevation — require planning permission
For the majority of rural Roseland and East Cornwall properties, the outdoor unit can be positioned in a rear garden, on a side wall, or on a low-visibility roof slope entirely within permitted development. We carry out a planning assessment as part of every free survey. Read our full guide: planning permission for heat pumps and solar in Cornwall.
Making the Switch: Oil to Heat Pump in Rural Cornwall
The typical oil-to-heat-pump process for a rural Cornish village property:
- Free home survey: We visit, carry out a full heat loss calculation, assess radiators, check the hot water cylinder, confirm grant eligibility, and provide a fixed-price quote with BUS grant deducted
- BUS grant application: We apply for the £7,500 voucher on your behalf — the process takes 2–4 weeks and the grant is deducted directly from your installation cost
- Installation: A typical oil-to-heat-pump installation takes 2–3 days. The oil tank is decommissioned and removed; the heat pump is positioned, commissioned, and integrated with existing pipework and radiators
- Aftercare: All our heat pump installations carry a 2-year labour guarantee and the manufacturer's warranty (typically 5–7 years for Daikin and Mitsubishi, extendable to 10 years with annual servicing)
