Before you book: air-to-air heat pumps in Islington
Most homes can run on a heat pump if the system is designed properly, and Islington is no different. The key is matching the heat pump and radiators to the home's heat loss.
Top-floor rooms in Islington that overheat in summer gain from the cooling an air-to-air system provides. For terraced homes in Islington, 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
- Homes where fitting radiators and pipework would be very disruptive
- Flats and apartments with storage or panel heaters
What's included
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- 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
- Outdoor unit and indoor units for each room
A survey in Islington covers indoor unit positions, pipe routes and hot water for homes across Greater London.
Grants and rules for heat pumps in England
Homes in Islington 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 in Islington: questions
How soon can you survey a home in Islington?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Islington that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Islington, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Islington?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Islington home states the expected time.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
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.
