Before you book: air-to-air heat pumps in Winchester
Most homes can run on a heat pump if the system is designed properly, and Winchester is no different. The key is matching the heat pump and radiators to the home's heat loss.
A survey in Winchester covers indoor unit positions, pipe routes and hot water for homes across Hampshire. For terraced homes in Winchester, 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.
- Households that already have, or will add, a separate source of hot water
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
What's included
- 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
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
Flats in Winchester on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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 Winchester quote.
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-to-air heat pumps costs around Winchester
The ranges below are typical installed prices for homes in Hampshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Winchester can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,450–£5,150 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,100–£8,250 |
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.
Designing for Winchester's winters
On the shortest day Winchester gets about 7 hours 54 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air-to-air heat pumps in Winchester: questions
How long does installation take in Winchester?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Winchester home states the expected time.
Do you cover Eastleigh as well as Winchester?
Yes. We arrange surveys and installation in Eastleigh, which is about 7 miles south of Winchester, and across Hampshire.
Can you service a heat pump in Winchester that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Winchester, whoever fitted them. Tell us the make and model when you book.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
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.
