How it works
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. From there, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Around Cowplain, access is usually simple, though gates and garden access are worth mentioning.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
How to prepare

Air source heat pumps in Cowplain, done properly
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Typical jobs include working out whether radiators need upsizing and a boiler that’s getting old, on hot water cylinders, air-to-air heat pumps and homes heated by oil, LPG or gas.
For a house near Cowplain, space outside is rarely the problem, so heat loss, radiators and the electrics are what we check.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

FAQs for Cowplain
Can you do air source heat pumps in Cowplain?
Yes. Cowplain is one of the places we cover. Get in touch with the details and we reply the same working day.
Is Cowplain within the area you cover?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is there VAT on a heat pump?
Not on a home installation at the moment: HMRC zero-rates heat pumps installed in residential accommodation until 31 March 2027, and 5% applies after that. Businesses and hotels pay the standard rate, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice.
Do I need new radiators for 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.
Am I eligible for a heat pump grant?
Not every home qualifies, so we check. There’s one grant per property, you cannot get one to replace a low-carbon system, and hybrids are excluded, among other rules.
Which manufacturers do you install and repair?
We work with the leading brands, 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.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Common problems we fix in Cowplain
A common reason is wanting to stop burning gas, oil or LPG. A heat pump runs on electricity and takes heat from the outside air, which is why it fits that aim.
If any of these sounds familiar, it’s worth a diagnosis:
- Replacing a combi boiler with a heat pump
- Checking whether planning permission is needed
- Questions about the Boiler Upgrade Scheme
Historic houses such as Warblington Castle, about 4.5 miles south-east, are a reminder that listed homes need consent before a heat pump goes in.
What your quote should include
- Whether anyone has checked the property or the system first
- Which brand and model they’re proposing, and why
- Whether extra work needs your approval first
Air source heat pumps in Cowplain: the local picture
About 58 miles out from central London, Cowplain is part of the South East area we work across. About 54% of homes in and around Cowplain date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 67% of households live in detached or semi-detached houses, according to the 2021 Census. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Period properties close to The Hart Plain Church can suit a heat pump, though insulation and any heritage protection are checked first.

Why it’s worth doing now in Cowplain
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. Dealing with it now is usually simpler than a breakdown later.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered and we will price it together.
