Hot water has to come from elsewhere, such as an existing immersion cylinder, an electric water heater or a separate hot water heat pump. In England and Wales, the Boiler Upgrade Scheme now includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026, subject to the scheme's conditions. The installer must be MCS-certified to apply, and the refrigerant work must be done by an F-gas certified engineer.
A survey in Berkshire covers indoor unit positions, pipe routes and hot water for homes across Berkshire. Extensions and garden rooms in Berkshire that are hard to connect to the main heating can have their own air-to-air unit. Flats in Berkshire on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Who it suits
- Flats and apartments with storage or panel heaters
- Rooms that get too hot in summer as well as cold in winter
- Households that already have, or will add, a separate source of hot water
- Homes where fitting radiators and pipework would be very disruptive
Grants and rules for heat pumps in England
Homes in Berkshire 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.
Air-to-air heat pumps prices in Berkshire
The ranges below are typical installed prices for homes in Berkshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Berkshire can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,550–£5,300 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,250–£8,500 |
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 questions
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.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
How much sound do the indoor units make?
Indoor units are designed to run quietly, with a fan you will hear most when heating or cooling at full output. Lower fan settings and night modes reduce sound in bedrooms. Siting matters for the outdoor unit too: it needs airflow and a position that passes the MCS noise assessment. Ask to see the sound levels of the proposed units at survey.
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.
