What to know about air-to-air heat pumps in Mitcham
A heat pump suits most Mitcham homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
A survey in Mitcham covers indoor unit positions, pipe routes and hot water for homes across Greater London. For terraced homes in Mitcham, 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.
- 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
What's included
- Condensate drains and neat external pipe covers
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Flats in Mitcham 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
Homes in Mitcham 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.
Guide prices for air-to-air heat pumps in Mitcham
These are guide prices for Greater London, 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.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,700–£5,600 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,500–£8,950 |
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 Mitcham's winters
Mitcham sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 37 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air-to-air heat pumps in Mitcham: questions
Do I need new radiators for a heat pump in Mitcham?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Mitcham home gives a room-by-room list.
Where would the outdoor unit go on a Mitcham house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Mitcham home.
Do you cover Morden as well as Mitcham?
Yes. We arrange surveys and installation in Morden, which is about a mile west of Mitcham, and across Greater London.
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.
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.
