How we handle air source heat pumps in Westmeston
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. Common call-outs are for an oil, LPG or gas boiler near the end of its life and replacing a combi boiler with a heat pump, on hot water cylinders, air-to-water heat pumps and homes heated by oil, LPG or gas.
Older and listed homes in villages like Westmeston need extra care, because permitted development does not apply within the grounds of a listed building, so we check consent first.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Westmeston: your questions answered
Can I get the Boiler Upgrade Scheme grant in Westmeston?
Westmeston is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. As an MCS certified installer, we apply for it on your behalf.
Is Westmeston 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.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book, and we are happy to show ours.
Do you have a 24/7 line?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. 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.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs, so the quote covers any changes.
Different systems, different jobs
VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote.
Radiators and underfloor heating
Underfloor heating works well with heat pumps because it uses lower temperatures and we look at it during the survey.
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. It takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. Work in Westmeston is booked in advance at a time that suits you.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Unlock any gate, garage or side passage we need
- Let us know if the units are on a roof, a high wall or in a locked area
- Plan for pets to be kept clear during the visit
Ask for a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.

When to call us in Westmeston
Homes with electric heating sometimes look at heat pumps as an alternative. The survey tells you whether it’s practical and what’s involved along with whether any grant could apply.
The things we are asked about most are:
- Comparing heat pump types
- Finding a place for the outdoor unit
- Replacing a combi boiler with a heat pump
With Preston Manor & Gardens about 4.9 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump.
What to look for in a quote
- What paperwork you’ll receive afterwards
- If the quote is based on a survey, photos or a diagnosis
- How VAT is shown, and which rate applies
Leave it or put it right?
A sudden boiler failure rarely leaves room to plan a heat pump properly. Surveying and designing in advance means the system is sized right and any grant is applied for before you need the heat. Booking before summer means the work in Westmeston is done before the hot weather.
What you pay reflects the actual work. That is why every job is looked at first, and why the quote is fixed before we start.

What a heat pump looks like in Westmeston
There are 2 conservation areas within a mile of the centre of Westmeston. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as The Parish Church of St Martin (grade II*). For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the local planning authority (typically Lewes council) where necessary. About 42% of homes in and around Westmeston date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 77% 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 normally have room for the outdoor unit and a cylinder.
Older homes near The Parish Church of St Martin may need extra checks for planning and heat loss before a heat pump is designed.
