About our air source heat pumps in Windmill Hill
We install air source heat pumps in Windmill Hill and across East Sussex, and we are MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We will explain which type fits your home and why. Common call-outs are for checking whether planning permission is needed and choosing between air-to-water and air-to-air, on underfloor heating, hot water cylinders and air-to-water heat pumps.
For a home around Windmill Hill that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Each manufacturer sets its own warranty period. For example, 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.

Keeping the system healthy
So the system stays in good health:
- Seal draughts where you can
- Diary the next service
- File the MCS certificate safely
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.

Common questions in Windmill Hill
Do I need planning permission for a heat pump in Windmill Hill?
It comes down to the building and the spot chosen for the outdoor unit. Around 16 listed entries sit within 0.5 miles of central Windmill Hill. 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 local planning authority (for Windmill Hill, normally Wealden council) first.
Do you cover smaller places like Windmill Hill?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Should I choose air-to-water or air-to-air?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
What VAT do I pay on a heat pump?
In residential accommodation, 0% until 31 March 2027 and 5% afterwards. The relief doesn’t cover businesses. Please treat this as general information, not tax advice.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Air source heat pumps around Windmill Hill
About 85% of households live in detached or semi-detached houses, according to the 2021 Census. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

What’s near Windmill Hill
Typical jobs here are in properties near The Brewers' Arms Inn. The nearest railway station is Normans Bay station, roughly 4.7 miles south-east of the centre. Well-known places in the area include Herstmonceux Castle (1.1 miles south) and Amberstone Hospital (2.8 miles west).
What owners can safely do
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call 07833 053749, or email if that’s easier.
What we are called out for in Windmill Hill
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
These are the situations we see most often:
- Wanting to stop using oil, LPG or gas for heating
- Not knowing whether a grant applies
- Ageing boilers that will need replacing
With Horselunges Manor about 4 miles west, it’s worth asking whether your own home is listed before planning a heat pump.

“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.”
