Air source heat pumps installed across the South West — Devon, Cornwall, Somerset, Dorset and Bristol — with the £7,500 Boiler Upgrade Scheme grant taken straight off your quote.
An air source heat pump pulls heat out of the outside air and uses it to warm your radiators and your hot water. It runs on electricity rather than gas or oil, and on a well designed system it will produce three or four units of heat for every unit of electricity it uses.
The government's Boiler Upgrade Scheme puts £7,500 towards an air-to-water heat pump in England and Wales. You do not apply for it yourself. The installer applies to Ofgem on your behalf and takes the money off the quote before you pay a penny, so the number you see is the number after the grant.
SWW installs heat pumps right across the South West under an MCS umbrella scheme, alongside our MCS certified partner. They handle the system design, the commissioning and the grant paperwork. We carry out the installation. Between us you get a fully MCS certified installation and the full grant, with one point of contact throughout, wherever in the South West the job is.
About the size and noise of a large fridge, sited outside on a wall bracket or ground frame. We'll talk through the best spot for yours at survey.
Anyone who tells you otherwise is going to disappoint you later.
Heat pumps run at a lower flow temperature than a gas boiler. Some radiators will need upsizing to give off the same heat. We work that out at survey rather than discovering it halfway through.
A proper heat loss calculation for the actual building. Undersize it and the house is cold. Oversize it and you have paid for capacity you never use.
Electricity costs roughly four times what gas does per unit. A heat pump only saves you money if it is running efficiently, which comes down to design and controls.
If a property is very leaky and cannot take the radiator work, we will say so. We would rather tell you at survey than take the job and leave you cold.
The South West has a lot of rural properties, from Devon and Cornwall up through Somerset and Dorset, that were never connected to mains gas and run on oil or LPG. Those are the houses where a heat pump makes the strongest case, because oil is expensive and the boiler needs a tank and a delivery lorry.
From 21 July 2026 the grant for eligible off-gas-grid properties replacing oil or LPG heating rises to £9,000. If that is your house, it is worth reading our guide to swapping an oil boiler for a heat pump before you commit to another oil boiler that will still be there in 2040.
Yes. We install air source heat pumps right across the South West — Devon, Cornwall, Somerset, Dorset and Bristol — under an MCS umbrella scheme, with the Boiler Upgrade Scheme grant applied and taken off your quote.
It depends on the size of the property and how much radiator work is needed, so we survey before quoting. The Boiler Upgrade Scheme takes £7,500 off the price of an eligible air-to-water heat pump, and the installer deducts it from your invoice rather than you claiming it back. From 21 July 2026 that rises to £9,000 for eligible off-gas-grid properties currently on oil or LPG.
Heat pump installations have to be MCS certified for the Boiler Upgrade Scheme grant to apply. We work under an MCS umbrella scheme with our MCS certified partner, who carries out the system design, the commissioning and the grant application to Ofgem. We do the installation. You get a fully certified installation, the full grant, and one number to ring, wherever in the South West the job is.
Some of them, usually. A heat pump runs at a lower flow temperature than a gas boiler, so a radiator that was fine at 70 degrees may not give off enough heat at 45. We measure the heat loss room by room and tell you which ones need to grow.
Your property needs to be in England or Wales, owned by you, with a valid EPC, and you must be replacing a fossil fuel system such as a gas, oil, LPG or direct electric heating. Properties that already have a heat pump do not qualify. We check all of it before quoting.
