Air source heat pumps in Deacon's Hill, done properly
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. Typical jobs include working out where a cylinder could go and plans to switch to electric heating with a heat pump, on homes heated by oil, LPG or gas, underfloor heating and air-to-water heat pumps.
In a place like Deacon's Hill, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

How it works
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we clear up before we go. Seeing the property in photos first means the trip to Deacon's Hill can be planned properly.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Tell us about any building rules, permits or sign-in

Looking after it afterwards
Systems last better with the right care. Here’s what we suggest:
- Ask about the grant before you commit
- Keep radiators clear
- Store the MCS certificate and warranty documents together
We show you how to use the controls and explain how a heat pump works differently from a boiler. Heat pumps tend to work best running steadily rather than in short bursts, and we will explain the settings for your home.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
FAQs for Deacon's Hill
Is Deacon's Hill within the area you cover?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Does the Boiler Upgrade Scheme cover homes in Deacon's Hill?
Yes, if the home and the heat pump meet the scheme’s rules: Deacon's Hill is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking, and we’re happy to show ours.
Is a heat pump permitted development?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings and their curtilages are excluded, and listed building consent is a separate matter. We check what applies to you.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
