Air source heat pumps for homes and businesses in Marehill
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. That follows HMRC Notice 708/6, and it does not apply to businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. The work covers radiator systems, underfloor heating and hot water cylinders, and people most often call us about checking whether planning permission is needed and checking emitters for a heat pump.
In a place like Marehill, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Homes in Marehill and heat pumps
About 41 miles out from central London, Marehill is part of the South East area we work across. There are 2 conservation areas within a mile of the centre of Marehill. Historic England lists about 9 buildings and structures within half a mile of the centre of Marehill, including Hulls Farmhouse (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
If your home is one of the older properties near Wiggonholt Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. If your home is listed, like Old Place Manor about 1.4 miles west, listed building consent comes before any heat pump work.
Marehill is about 10 miles north of Worthing, in West Sussex. From the centre of Marehill to the outskirts, our engineers cover air source heat pumps, from small jobs to large ones.

Marehill: your questions answered
Do you cover smaller places like Marehill?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I get the Boiler Upgrade Scheme grant in Marehill?
Marehill is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. The installer applies, and we’re MCS certified.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
How long does a heat pump installation take?
As a guide, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. We plan the work so you are without heating for as little time as possible, and we explain it in advance.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Will my radiators work with a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.

Different systems, different jobs
The Boiler Upgrade Scheme
The Boiler Upgrade Scheme covers England and Wales: £7,500 for air-to-water (and ground source), and £2,500 for air-to-air with strict conditions. The application goes through the installer.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
Why it’s worth doing now in Marehill
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. Booking before summer means the work in Marehill is done before the hot weather.
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.

The process
Each visit follows the same order: agree the plan on site, protect the area, do the work, test what we have done and talk you through it. The visit itself takes a few days for most air-to-water installations, with air-to-air systems often quicker. Somewhere like Marehill, it helps to know about lanes, gates and where to park.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Getting ready for the visit
- Let us know where the consumer unit is
- Make sure someone can let us in at the agreed time
- Clear the space around the indoor unit, or where it will go

Advice
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.”
