Air-to-air heat pumps for Tooting homes
Every property in Tooting is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Top-floor rooms in Tooting that overheat in summer gain from the cooling an air-to-air system provides. Installers in Tooting plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
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
- Rooms that get too hot in summer as well as cold in winter
- Flats and apartments with storage or panel heaters
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Electrical supply and controls set up for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
Flats in Tooting 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 Tooting 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.
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 prices in Tooting
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.
Winter daylight and heating in Tooting
On the shortest day Tooting gets about 7 hours 50 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.
The steps for air-to-air heat pumps in Tooting
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Tooting home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air-to-air heat pumps in Tooting: questions
Do you cover Balham as well as Tooting?
Yes. We arrange surveys and installation in Balham, which is about a mile north-east of Tooting, and across Greater London.
Do I need new radiators for a heat pump in Tooting?
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 Tooting home gives a room-by-room list.
Can you service a heat pump in Tooting that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tooting, whoever fitted them. Tell us the make and model when you book.
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.
