We cover 18 towns and cities in Devon, including Plymouth, Exeter, Paignton and Torquay. Every installation is designed from a room-by-room heat loss calculation, so the heat pump, radiators and cylinder are sized for the house rather than guessed.

Grants and rules for heat pumps in England
Homes in Devon can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Questions
Can I have a heat pump in a flat or a small home?
Yes, many flats and small homes can have a heat pump, usually a smaller unit of around 4–5 kW. For a flat, the key questions are where the outdoor unit can go, such as a balcony, wall or yard, and whether the freeholder agrees. Flats may also need planning permission, depending on the rules in your nation, which we check at survey. In small homes the usual limit is cylinder space. Where a wet system will not fit, an air-to-air heat pump can heat individual rooms.
Should I leave my heat pump running all the time?
Usually yes: a heat pump works most efficiently running steadily at a low flow temperature, rather than switching on and off like many boilers. Weather compensation controls adjust the flow temperature to the weather outside, so the system keeps rooms comfortable using less energy. You can still lower temperatures overnight or when you are away, but large set-backs make the heat pump work harder to recover. We set up the controls and show you how they work.
Do I need new radiators for a heat pump?
Whether you need new radiators depends on each room's heat loss: some homes need a few larger radiators, while others can keep most of their existing ones. Heat pumps run most efficiently at low flow temperatures, around 35–50°C, so a radiator gives out less heat than it did with a boiler. The room-by-room heat loss calculation shows which rooms need a bigger radiator. A replacement radiator sized for a heat pump is a guide price of £250–£450 each, installed and including VAT.
How do I pay for my heat pump installation?
How and when you pay is set out in your written quote, so you know the full price and any payment stages before you agree to anything. Nothing is ordered until you accept the quote. Where a grant applies, such as the Boiler Upgrade Scheme in England and Wales, it is deducted from the price shown. If you have questions about payment, ask at the survey and we will explain how it works for your job.
