Air source heat pumps in Hill Green
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home; adding it alongside a boiler doesn’t qualify. The work covers underfloor heating, hot water cylinders and homes heated by oil, LPG or gas, and common reasons people get in touch are questions about where the outdoor unit can go and ageing boilers that will need replacing.
Homes around Hill Green typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What owners can safely do
There are a few things you can safely do yourself: 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 makes our diagnosis quicker, and a photo of the display helps even more.
The process
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a place like Hill Green, the timing is set with you and the travel is our side of the planning.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Keep pets out of the rooms we are working in
- Dig out any previous service or F-Gas records
- Arrange for someone to be there to let us in
How to get a quote
Every quote shows the VAT clearly, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone us on 07833 053749 or email us.

After we have gone
Looking after it is simple, and it helps at the next service:
- Do not block radiators or indoor units with furniture
- Avoid switching the heat pump on and off often
- Clear leaves and debris from the outdoor unit
If anything does not seem right after installation, call 07833 053749 or fill in the contact form and we will look into it. Annual servicing helps keep the system working well.
Do not cover radiators with furniture or heavy curtains so the heat can get into the room.
Homes in Hill Green and heat pumps
The last census (2021) found about 81% of households in detached or semi-detached houses. Houses typically have space for an outdoor unit and a hot water cylinder.
If your home is listed, like Audley End House about 4.2 miles north-east, listed building consent comes before any heat pump work. Live in one of the older houses around Church of St Mary and St Clement? Expect the survey to look closely at heat loss and at the building’s planning status.

Hill Green questions
Will a heat pump in Hill Green need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The Hill Green Conservation Area is close to the centre of Hill Green. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Uttlesford council, usually the authority for Hill Green.
Do you cover smaller places like Hill Green?
Yes. Hill Green is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Should I choose air-to-water or air-to-air?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Different systems, different jobs
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, so radiator sizes matter.
Outdoor unit position and planning
Flats have tighter limits, and an Article 4 direction can remove permitted development rights. Listed building consent is a separate matter, and we check the position for your property.
From one of our customers
“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.”
