Before you book: air source heat pump installation in Chippenham
The question for a Chippenham home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Installers working in Chippenham plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Chippenham 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
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
What's included
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- MCS registration and certificate, plus network operator notification
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
In Chippenham, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in England
Homes in Chippenham 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Air source heat pump installation in Chippenham: questions
How long does installation take in Chippenham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Chippenham home states the expected time.
Where would the outdoor unit go on a Chippenham house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Chippenham home.
How soon can you survey a home in Chippenham?
Survey dates depend on how busy installers are in Wiltshire. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
