About our air source heat pumps in Rush Green
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. Typical jobs include ageing boilers that will need replacing and checking eligibility for a heat pump grant, across homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps.
Space for an outdoor unit is rarely an issue near Rush Green, so the design comes down to heat loss, radiators and hot water.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the existing unit help with repairs and servicing in Rush Green.
- We find out about your home and the heating you have now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- We install, commission and register the system under MCS.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any managing agent or landlord rules we need to follow
- Keep pets and children away from the work area

Common questions in Rush Green
Does the Boiler Upgrade Scheme cover homes in Rush Green?
Yes, if the home and the heat pump meet the scheme’s rules: Rush Green is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Do you cover Rush Green for air source heat pumps?
Yes. We work across London and the South East from our base in East Grinstead, and Rush Green is part of that. Get in touch with the details and we reply the same working day.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How long will it take to install a heat pump?
As a guide, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. We plan the work so you are without heating for as little time as possible, and we explain it in advance.
Which type of heat pump is right for my home?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. Both are part of what we install.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Do you have a 24/7 line?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.

Air source heat pumps in Rush Green: the local picture

Historic houses such as Knebworth House, about 2.1 miles south-east, are a reminder that listed homes need consent before a heat pump goes in. Every heat pump design starts with a room-by-room heat loss calculation.

Owner checks or an engineer?
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
