Before you book: air-to-air heat pumps in Wandsworth
Homes around Wandsworth 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 Wandsworth that are hard to connect to the main heating can have their own air-to-air unit. Top-floor rooms in Wandsworth that overheat in summer gain from the cooling an air-to-air system provides.
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.
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
- Outdoor unit and indoor units for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
A survey in Wandsworth 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 Wandsworth 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 Wandsworth

Short winter days in Wandsworth and what they mean
Wandsworth sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 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.
How installation works in Wandsworth
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Wandsworth 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 Wandsworth: questions
Can you service a heat pump in Wandsworth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wandsworth, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Wandsworth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Wandsworth home states the expected time.
Do I need new radiators for a heat pump in Wandsworth?
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 Wandsworth home gives a room-by-room list.
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.
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.
