Air source heat pump installation in Keynsham: what to expect
Most homes can run on a heat pump if the system is designed properly, and Keynsham is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners across Somerset can arrange a survey in Keynsham for a room-by-room design and a written quote before committing to anything. In Keynsham, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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.
- Owners who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
- System design, unit sizing and a written quote
For older properties in Keynsham, 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
Homes in Keynsham 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.
What to budget for air source heat pump installation in Keynsham
The ranges below are typical installed prices for homes in Somerset, including VAT. A survey sets the exact figure, because two similar-looking houses in Keynsham can need quite different radiators and pipework.

| 1–2 bedroom flat or small terrace | 4–5 kW | £9,500–£12,500 | £2,000–£5,000 |

Short winter days in Keynsham and what they mean
Keynsham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 37 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 Keynsham: questions
How long does installation take in Keynsham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Keynsham home states the expected time.
Can you service a heat pump in Keynsham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Keynsham, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Keynsham?
Survey dates depend on how busy installers are in Somerset. We offer the next available dates when you enquire and confirm them in writing.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
