About our air source heat pumps in Saint Hill Green
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb is not good enough. If you are dealing with comparing heat pump types and finding a place for the outdoor unit, we can sort it out.
Older and listed homes in villages like Saint Hill Green need extra care, and permitted development doesn’t cover listed buildings, so we check consent first.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

How the job changes from property to property
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
Heat loss surveys
We look at walls, windows, floors, roofs and ventilation, and the size of each room.
Homes in Saint Hill Green and heat pumps
About 52% of homes in the Saint Hill Green area date from 1945 to 1972, according to VOA council tax data, and about 78% of households live in detached or semi-detached houses, according to Census 2021 figures. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Older homes near St. Barnabas Church may need extra checks for planning and heat loss before a heat pump is designed.

What else we do in Saint Hill Green
What we’re called out for in Saint Hill Green
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
Any of these is worth a proper look:
- Plans to switch to electric heating with a heat pump
- A boiler that’s getting old
- Deciding which kind of heat pump suits the home
Saint Hill Manor lies about 0.1 miles north-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
Before booking anyone
- What’s in the price and what is not
- Whether a new circuit is included and who certifies it
- Whether they looked at the job before pricing it
Questions from Saint Hill Green
Is the heat pump grant available in Saint Hill Green?
Yes, the scheme covers homes in England, including Saint Hill Green, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. You do not apply yourself: the MCS certified installer does, which is us.
Is planning permission needed for a heat pump in Saint Hill Green?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 8 buildings and structures within half a mile of the centre of Saint Hill Green. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Saint Hill Green, typically Mid Sussex council) first.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Will my radiators work with a heat pump?
It varies from room to room. The survey compares each radiator with the room’s needs, so the quote covers any changes.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
What does an air-to-water heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.
Looking after it afterwards
Once we have finished, these simple steps help:
- Find out the grant position at the survey
- Keep the MCS certificate with the manufacturer’s paperwork
- Leave indoor units unobstructed
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Book a service every year. Check the manufacturer’s terms, as they may include servicing conditions.
The process
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes several days for an air-to-water system with a new cylinder, less for an air-to-air system, and we tidy up before we leave. Seeing the property in pictures first means the trip to Saint Hill Green can be planned properly.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Make sure someone can let us in at the agreed time
- Have the make and model of any existing unit to hand
- Clear a path to the units and the space around them
