Air-to-air heat pumps in Streatham: what to expect
Most homes can run on a heat pump if the system is designed properly, and Streatham is no different. The key is matching the heat pump and radiators to the home's heat loss.
A survey in Streatham covers indoor unit positions, pipe routes and hot water for homes across Greater London. Extensions and garden rooms in Streatham that are hard to connect to the main heating can have their own air-to-air unit.
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.
- Flats and apartments with storage or panel heaters
- 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
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Condensate drains and neat external pipe covers
- 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
- Free survey covering rooms to heat, unit positions and hot water options
For terraced homes in Streatham, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
Grants and rules for heat pumps in England
Homes in Streatham 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.
Air-to-air heat pumps prices in Streatham
Here are typical prices for air-to-air heat pumps in Greater London, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.

Designing for Streatham's winters
Streatham sees roughly 7 hours 50 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.
How installation works in Streatham
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Streatham; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Streatham: questions
What size heat pump does a Streatham 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 Streatham home.
How long does installation take in Streatham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Streatham home states the expected time.
Can you service a heat pump in Streatham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Streatham, whoever fitted them. Tell us the make and model when you book.
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.
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.
