- No space for a hot water cylinder
- Checking whether planning permission is needed
- Ageing boilers that will need replacing
How the visit works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. A few pictures let us plan a visit to a place like Westergate.
- First we talk through the property and the current system.
- 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.
- We install, commission and register the system under MCS.
How to prepare
- Keep pets out of the rooms we’re working in
- Clear a path to the units and the space around them
- Tell us about any building rules, permits or sign-in

Air source heat pumps for homes and businesses in Westergate
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. If the problem is questions about where the outdoor unit can go and deciding which kind of heat pump suits the home, we can sort it out.
If your home near Westergate has no mains gas, the grant can be bigger. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027, for an air source or ground source heat pump.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Why deal with it now?
The two types suit different homes and needs. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions. We explain which makes sense for you. A system that’s left with a fault, or without a service, typically costs more to run.
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. The price is fixed before any work starts, with VAT shown clearly.

What else we do in Westergate
Common questions in Westergate
Is the heat pump grant available in Westergate?
Westergate is covered, as the scheme runs across England and Wales. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.
Is Westergate 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.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Is a heat pump permitted development?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings are excluded, and listed building consent is separate. We check what applies to you.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Heat pumps in Westergate: local notes
The Parish Church of St George, listed at grade II*, is one of roughly 29 protected buildings and structures in the half-mile around Westergate’s centre. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? The Valuation Office Agency’s council tax figures show about 35% of homes in and around Westergate were built in 2000 or later, and the last census (2021) found about 71% of households in detached or semi-detached houses. Better insulated, newer homes are often a good match for a heat pump. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
If your home is listed, like Goodwood House about 4 miles north-west, listed building consent comes before any heat pump work.

Owner checks or an engineer?
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Common problems we fix in Westergate
People also ask about air-to-air heat pumps because they heat and cool. They heat rooms through wall, floor or ceiling units and switch to cooling in warm weather. Whether a grant applies depends on the scheme conditions.
Look out for these signs:
- Wanting to stop using oil, LPG or gas for heating
- Checking eligibility for a heat pump grant
- Ageing boilers that will need replacing
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
