Air-to-air heat pumps for Sutton homes
Homes around Sutton range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Extensions and garden rooms in Sutton that are hard to connect to the main heating can have their own air-to-air unit. Installers in Sutton 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.
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
- Households that already have, or will add, a separate source of hot water
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
- 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
- Condensate drains and neat external pipe covers
A survey in Sutton covers indoor unit positions, pipe routes and hot water for homes across Greater London.
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 Sutton quote.
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 costs around Sutton
Guide prices for Sutton and the rest of Greater London are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| 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 Sutton's winters
On the shortest day Sutton gets about 7 hours 51 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.

Air-to-air heat pumps in Sutton: questions
How long does installation take in Sutton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sutton home states the expected time.
What size heat pump does a Sutton home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Sutton home.
Where would the outdoor unit go on a Sutton 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 Sutton home.
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.
