FAQs for Harmondsworth
Can I have air conditioning in a flat in Harmondsworth?
Often, yes, but the lease and the freeholder usually have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is planning permission needed for a heat pump in Harmondsworth?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Harmondsworth is in the Harmondsworth Village Conservation Area. 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 Hillingdon council, which is usually the planning authority for Harmondsworth.
Is Harmondsworth in your area?
Yes. We cover Harmondsworth and the rest of Greater London, within the London and South East area we cover. For a fixed-price quote, ring us on 07833 053749 or drop us a line.
How much VAT is charged on a heat pump in a home?
Not on a home installation at the moment: until 31 March 2027 the rate is 0% in residential accommodation, then 5%. Businesses and hotels pay the standard rate, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice.
Which type of heat pump is right for my home?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. We install both types.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
About our air source heat pumps in Harmondsworth
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. Typical jobs include working out where a cylinder could go and questions about the Boiler Upgrade Scheme, on air-to-water heat pumps, air-to-air heat pumps and hot water cylinders.
In a flat in Harmondsworth, the lease and the freeholder normally decide where a heat pump can go. Permitted development limits are different for flats, and we check before designing.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

What a heat pump looks like in Harmondsworth
London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Every heat pump design starts with a room-by-room heat loss calculation. If your home is one of the older properties near Church of St Mary, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

What the work involves, system by system
The Boiler Upgrade Scheme
In England and Wales, the Boiler Upgrade Scheme offers grants towards heat pumps: £7,500 for air-to-water (and ground source), and £2,500 for air-to-air with strict conditions. The installer applies.
Radiators and underfloor heating
Any radiator changes are set out in the quote, so the work is clear.
The process
If the system has to be off for part of the visit, we tell you before we start, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and where the outdoor unit could go let us plan most of a visit to Harmondsworth in advance.
- We find out about your home and the heating you have now.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
Preparing for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Clear a path to the units and the space around them
- Mention any parking restrictions near the property
