Air source heat pump installation in Totnes: what to expect
Most homes can run on a heat pump if the system is designed properly, and Totnes is no different. The key is matching the heat pump and radiators to the home's heat loss.
In Totnes, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Terraced streets in Totnes often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
For older properties in Totnes, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Totnes quote.
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.

How long is the heating season in Totnes?
Totnes sees roughly 8 hours 00 minutes of daylight in late December against 16 hours 27 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Air source heat pump installation in Totnes: questions
What size heat pump does a Totnes home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Totnes home.
Do you cover Paignton as well as Totnes?
Yes. We arrange surveys and installation in Paignton, which is about 5 miles east of Totnes, and across Devon.
How long does a heat pump survey take in Totnes?
A home survey in Totnes usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
