How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. For a village like Mill Green, tell us about narrow lanes, gates and parking when you book.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Getting ready for the visit
- Keep pets and children away from the work area
- Tell us about parking and loading
- Dig out any previous service or F-Gas records

About our air source heat pumps in Mill Green
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. If you’re dealing with ageing boilers that will need replacing and planning and permitted development questions, we can help.
In a place like Mill Green, some homes are listed, and permitted development doesn’t cover listed buildings, so we check consent first.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

What the work involves, system by system
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. A unit used solely for cooling isn’t covered and need a check with the council.
Outdoor unit position and planning
The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
Pricing air source heat pumps in Mill Green
Jobs vary more than people expect. What affects the quote:
- Whether it’s a one-off job or part of a maintenance contract
- Access, including height, roofs and ladders
- What electrical work the job needs
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. You will have a fixed price before we start, and the quote sets out the VAT.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Where the property is and what kind of building it is
- Your installation or service records
- A few pictures of the room and the wall the unit is on, or will go on
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Homes in Mill Green and heat pumps
The Valuation Office Agency’s council tax figures date about 46% of homes across Mill Green and its surrounding area to the post-war years, 1945 to 1972, and about 72% of households live in detached or semi-detached houses, according to the 2021 Census. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Period properties close to Church of St Mary the Virgin can suit a heat pump, though insulation and any heritage protection are checked first. Ingatestone Hall, roughly 1.9 miles south-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

FAQs for Mill Green
Will a heat pump in Mill Green need planning permission?
It depends on the property. There’s a conservation area, the Fryerning Conservation Area, close to central Mill Green. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with the planning department at Brentwood council, normally the authority for Mill Green.
Will you come out to Mill Green?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Which type of heat pump is right for my home?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases. We explain the options after the survey.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Only in limited cases, with a grant of £2,500. It has to replace the fossil-fuel heating, meet the full heating demand, be fitted by an MCS certified installer, and be in a home.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
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.
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 before we leave.
