Heat pump installation in Ayot Green, Hertfordshire
Our engineers work in Ayot Green on air source heat pumps. A look at the job first, a fixed-price quote and written records at the end.
- Comparing heat pump types
- Finding a place for the outdoor unit
- Planning and permitted development questions
What we do, step by step
Protection comes first: 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. Work in Ayot Green is booked in advance at a time that suits you.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- Then it’s fitted, commissioned and registered with MCS.
Before we arrive
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about parking and loading
Get a fixed-price quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.

Air source heat pumps in Ayot Green
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Guesswork leads to systems that are too big or too small. We’re often asked to deal with choosing between air-to-water and air-to-air and ageing boilers that will need replacing, across homes heated by oil, LPG or gas, underfloor heating and air-to-air heat pumps.
Homes around Ayot Green typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
AirCon Doctor is an F-Gas certified company and 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.

Your questions about air source heat pumps in Ayot Green
Does the Boiler Upgrade Scheme cover homes in Ayot Green?
Ayot Green is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we are MCS certified.
Will you come out to Ayot 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.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Ayot Green and across Hertfordshire. Let us know who the records should go to.
Is there a survey before the work?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Homes in Ayot Green and heat pumps
The Ayot Green Conservation Area is within about a third of a mile of the centre of Ayot Green. In the mile around Ayot Green’s centre, 2 conservation areas have been designated. About 15 listed entries lie within half a mile of central Ayot Green, Manor Farm (grade II) among them. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the local planning authority (usually Welwyn Hatfield council) where necessary. About 38% of homes in and around Ayot Green have been built since 2000, according to Valuation Office Agency council tax records, and Census 2021 figures found about 61% of households in detached or semi-detached houses. Better insulated, newer homes are often a good match for a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near Church of St Peter, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Digswell House, roughly 1.1 miles east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so each one has its own history.
What affects the quote in Ayot Green
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- The type of system, from a single split to a larger system
- The distance and route between the indoor and outdoor units
- Access, including height, roofs and ladders
What you pay reflects the actual work. That’s why every job is looked at first, and the price is agreed before work begins.
Before you get in touch
When you contact us, it’s useful to have:
- Your installation or service records
- Photos showing the indoor unit and the space around it
- The address and the type of property
For a fixed-price quote, call 07833 053749 or send an email and tell us about the property and what you need. Photos help a lot. You’ll hear back from us the same working day.

Before you book, it helps to know what’s not included:
- Grants for hybrid systems or replacements of low-carbon systems
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Getting planning permission or listed building consent on your behalf
