Before you book: air-to-air heat pumps in Westbury-on-Trym
Every property in Westbury-on-Trym 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.
Top-floor rooms in Westbury-on-Trym that overheat in summer gain from the cooling an air-to-air system provides. For terraced homes in Westbury-on-Trym, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
- Extensions, conservatories and garden rooms
What's included
- Electrical supply and controls set up for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
A survey in Westbury-on-Trym covers indoor unit positions, pipe routes and hot water for homes across Bristol.
Grants and rules for heat pumps in England
Homes in Westbury-on-Trym 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.
What to budget for air-to-air heat pumps in Westbury-on-Trym
These are guide prices for Bristol, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,100–£8,150 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.

Air-to-air heat pumps in Westbury-on-Trym: questions
Do you cover Bishopston as well as Westbury-on-Trym?
Yes. We arrange surveys and installation in Bishopston, which is about a mile south-east of Westbury-on-Trym, and across Bristol.
How long does a heat pump survey take in Westbury-on-Trym?
A home survey in Westbury-on-Trym 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.
Can you service a heat pump in Westbury-on-Trym that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Westbury-on-Trym, whoever fitted them. Tell us the make and model when you book.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
