Before you book: air source heat pump installation in Gerrards Cross
Every property in Gerrards Cross is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Many homes in Gerrards Cross have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. In Gerrards Cross, 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
- Households with room for a hot water cylinder
- Houses with reasonable insulation, or a plan to improve it
What's included
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- 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 Gerrards Cross, 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 Gerrards Cross 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.

Air source heat pump installation in Gerrards Cross: questions
Can you service a heat pump in Gerrards Cross that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Gerrards Cross, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Gerrards Cross?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Gerrards Cross home states the expected time.
How soon can you survey a home in Gerrards Cross?
Survey dates depend on how busy installers are in Buckinghamshire. 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.
