An air-to-air heat pump takes heat from the outside air and delivers it straight into rooms as warm air through indoor units, usually mounted high on a wall. The same system can run in reverse to cool rooms in summer. Unlike an air-to-water heat pump, it does not use radiators or underfloor heating and does not heat a hot water cylinder.
Flats in Mid Glamorgan on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. A survey in Mid Glamorgan covers indoor unit positions, pipe routes and hot water for homes across Mid Glamorgan. Extensions and garden rooms in Mid Glamorgan that are hard to connect to the main heating can have their own air-to-air unit.
Who it suits
- Extensions, conservatories and garden rooms
- 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
Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.
Air-to-air heat pumps prices in Mid Glamorgan
The ranges below are typical installed prices for homes in Mid Glamorgan, including VAT. A survey sets the exact figure, because two similar-looking houses in Mid Glamorgan can need quite different radiators and pipework.

| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |

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.
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.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies at survey.
