Air source heat pumps in Hammerwood, done properly
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Sizing by rule of thumb is not good enough. If you are dealing with checking emitters for a heat pump and questions about listed buildings or conservation areas, we can help.
Homes around Hammerwood typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

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. Cooling-only units are not included, so check with the council.
Air-to-water heat pumps
Flow temperatures are lower than with a typical boiler, which is why radiator sizing is part of the survey.
Looking after your system
To keep the system working properly:
- Keep up with insulation and draught-proofing
- Store the MCS certificate and warranty documents together
- Check what your manufacturer’s warranty asks of you
If anything doesn’t seem right after installation, ring us on 07833 053749 and we will talk it through. Annual servicing helps keep the system working well.
Let the heat pump run steadily rather than switching it on and off as explained at handover.

How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and the outside of the property help us plan a visit to Hammerwood.
- It begins with your house and the heating it relies on now.
- 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.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we are working in

Air source heat pumps around Hammerwood
About 64% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses typically have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near Church of St Stephen, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Hammerwood Park lies about 0.8 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
Hammerwood is about 3 miles east of East Grinstead, in West Sussex. Whatever kind of property you have in Hammerwood, we can help with air source heat pumps. You will hear back from us the same working day and our emergency line runs 24/7. Our list for West Sussex has 371 entries, and Hammerwood is one.
Not far from Hammerwood, a recent job of ours was on Cantelupe Road, East Grinstead (RH19), about 3 miles west: installing a Mitsubishi Electric MSZ-LN wall-mounted split system in the master bedroom and a second unit in the open-plan kitchen-diner.

Questions from Hammerwood
Is the heat pump grant available in Hammerwood?
Yes, the scheme covers homes in England, including Hammerwood, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Can I fit a heat pump in Hammerwood without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 6 buildings and structures within half a mile of the centre of Hammerwood. 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 planning department at Mid Sussex council, typically the authority for Hammerwood first.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Is Hammerwood in your area?
Yes. We cover Hammerwood and across West Sussex, within the London and South East area we cover. To book, ring us on 07833 053749.
Do you look at the job first?
Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.
How soon will you get back to me?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
