Your questions about air source heat pumps in Windmill Hill
Is the heat pump grant available in Windmill Hill?
Windmill Hill is in England, where the Boiler Upgrade Scheme runs. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. We hold MCS certification, so the application is ours to make for you.
Does sea air affect air conditioning in Windmill Hill?
It can, as Windmill Hill is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Will I need planning consent for an air source heat pump?
Often not in England, as many heat pumps on houses are permitted development provided the conditions are met. These include an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), not being used solely for cooling and not being within the curtilage of a listed building.
Do you cover Windmill Hill?
Yes. Windmill Hill is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Can you come out in an emergency?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
How we handle air source heat pumps in Windmill Hill
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. We are often asked to deal with deciding on the outdoor unit position and wanting to stop using oil, LPG or gas for heating, across radiator systems, homes heated by oil, LPG or gas and underfloor heating.
Homes around Windmill Hill usually have space for an outdoor unit and a hot water cylinder, so the main questions are heat loss, radiators and the electrics.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Leave it or put it right?
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. 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 near Windmill Hill is done before the hot weather.
Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account and give you a fixed price before we start.

What a heat pump looks like in Windmill Hill
The coast is only about 2 miles from Windmill Hill. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. Central Windmill Hill is inside the Windmill Hill, Gravesend Conservation Area. There are 10 conservation areas within a mile of the centre of Windmill Hill. Historic England lists about 50 buildings and structures within half a mile of the centre of Windmill Hill, including The Town Hall (grade II*). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with Gravesham council, normally the planning authority here where needed. VOA council tax data put about 47% of homes in and around Windmill Hill before 1919. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump.
Older homes near Christ Church Milton may need extra checks for planning and heat loss before a heat pump is designed.

What we’re called out for in Windmill Hill
Air-to-air systems interest people who want cooling in summer as well as heating. They heat rooms through wall, floor or ceiling units, and can cool them when it’s hot. Whether a grant applies depends on the scheme conditions.
The things we’re asked about most include:
- Wanting to stop using oil, LPG or gas for heating
- No space for a hot water cylinder
- Ageing boilers that will need replacing
Historic houses such as Cobham College, about 3.3 miles south, are a reminder that listed homes need consent before a heat pump goes in.
What your quote should include
- Whether testing, commissioning and paperwork are included
- Whether anyone has checked the property or the system first
- Why the equipment they’re quoting suits the job
