About our air source heat pumps in Hounslow
We install air source heat pumps in Hounslow and across Greater London, and we are MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We help you work out which suits your home. Typical jobs include deciding on the outdoor unit position and replacing a combi boiler with a heat pump, on radiator systems, air-to-air heat pumps and air-to-water heat pumps.
Homes in Hounslow are often flats and terraces, where outside space is limited, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and typically a cylinder, while air-to-air units take less room.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Diary the next service
- Look at insulation alongside the heat pump
- Find out the grant position at the survey
If anything doesn’t seem right after installation, ring 07833 053749, or email if that’s easier and we’ll look into it. A yearly service is a good habit.
Heat pumps prefer steady, low-temperature running, using the settings agreed at handover.
What happens if it’s left?
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. It’s a date to bear in mind when planning, though the right time also depends on your home and heating. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Hounslow early.

Advice
Air source heat pumps around Hounslow
About 30% of homes across Hounslow and its surrounding area have been built since 2000, according to VOA council tax data, and the 2021 Census found about 49% of households live in flats. Better insulated, newer homes are often a good match for a heat pump. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. In London, outside space and the rules for flats often decide which kind of heat pump suits.
If your home is listed, like Osterley House about 1.6 miles north, listed building consent comes before any heat pump work. Homeowners near Hounslow station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.

FAQs for Hounslow
Is planning permission needed for a heat pump in Hounslow?
There’s no single answer: the building and the outdoor unit position decide it. Around 6 listed entries sit within 0.5 miles of central Hounslow. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Hounslow council, usually the authority for Hounslow.
Can I get the Boiler Upgrade Scheme grant in Hounslow?
Yes, the scheme covers homes in England, including Hounslow, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. The installer applies, and we’re MCS certified.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Are my radiators big enough for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs, so the quote covers any changes.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
