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 Bedfordshire covers indoor unit positions, pipe routes and hot water for homes across Bedfordshire. Top-floor rooms in Bedfordshire that overheat in summer gain from the cooling an air-to-air system provides. Flats in Bedfordshire on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Who it suits
- Rooms that get too hot in summer as well as cold in winter
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
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 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 questions
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.
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.
