Exeter and the wider Devon region have become one of the UK's most active heat pump markets, driven by a large number of off-gas-grid properties and a progressive city council committed to net zero. If you are looking for a heat pump installer in Exeter, the South West has an excellent network of MCS-certified companies with deep experience in both urban and rural installations.
Heat pump costs in Exeter are competitive for the South West, with most air source installations costing between £8,500 and £13,000 before the grant. The £7,500 BUS subsidy brings the net cost to £1,000 to £5,500. For Devon homeowners currently on oil heating, the combined savings on fuel bills and the grant make the financial case overwhelming, with typical payback periods of just 3 to 5 years.
Exeter enjoys the mild South West climate, with average winter temperatures of 4 to 7 degrees. Devon's gentle, maritime-influenced weather provides near-ideal conditions for air source heat pumps, which achieve their highest seasonal efficiency in mild, humid air. The region rarely experiences frost for more than a few days at a time, meaning heat pumps can maintain a COP of 3.0 or higher for the vast majority of the heating season.
Why Exeter homeowners are switching
Devon has one of the highest concentrations of off-gas-grid homes in England, with many properties relying on expensive oil or LPG heating. For these homeowners, switching to a heat pump delivers savings of £400 to £800 per year, making the payback period remarkably short once the £7,500 BUS grant is applied. Exeter City Council has declared a climate emergency with a 2030 net zero target, and the city is growing rapidly with new housing developments that increasingly include heat pumps as standard. The University of Exeter's world-leading climate research has also raised awareness among the local population about the importance of decarbonising home heating.
Exeter housing stock and installation
Exeter's city centre has a mix of Victorian terraces in areas like St Thomas and Mount Pleasant, alongside post-war suburban estates in Pinhoe, Whipton, and Countess Wear. The rapidly expanding new developments at Cranbrook and Monkerton are being built with heat pumps from the ground up. Beyond the city, Devon's villages and market towns feature traditional stone and cob properties, many with large gardens that suit ground source as well as air source installations. The rural properties in the surrounding Exe Valley and Dartmoor fringe are among the biggest beneficiaries of heat pump technology, finally escaping the high cost of oil and LPG.
