Air source heat pumps in Coggins Mill
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Eligibility depends on the property, so we confirm it before anything is agreed. Common call-outs are for questions about the Boiler Upgrade Scheme and moving away from fossil-fuel heating, across homes heated by oil, LPG or gas, air-to-air heat pumps and radiator systems.
Homes around Coggins Mill usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

What else we do in Coggins Mill
What owners can safely do
Owners can handle the everyday basics: 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: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
Leave it or put it right?
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. Getting the date in early helps for a place like Coggins Mill.
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.

Coggins Mill: your questions answered
Is the heat pump grant available in Coggins Mill?
Coggins Mill is in England, where the Boiler Upgrade Scheme runs. 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. We hold MCS certification, so the application is ours to make for you.
Do you cover smaller places like Coggins Mill?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How much does an air source heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
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. The survey helps decide. Both are part of what we install.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Is a heat pump permitted development?
That depends on your home and the unit’s position. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights, so we check during the survey.
Air source heat pumps in Coggins Mill: the local picture
Coggins Mill’s centre is no more than about a third of a mile from the Coggins Mill Conservation Area. Draw a one-mile circle round the middle of Coggins Mill and it takes in 2 conservation areas. About 14 listed entries lie within half a mile of central Coggins Mill, Wych Elm Cottage (grade II) among them. For a heat pump, permitted development does not 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 the planning team at Wealden council, which usually handles Coggins Mill where necessary. About 42% of homes in the Coggins Mill area were built before 1919, according to VOA council tax data, and the 2021 Census found about 75% of households in detached or semi-detached houses. 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. Houses usually have space for an outdoor unit and a hot water cylinder.
Wadhurst Castle, roughly 3.5 miles north-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. Older homes near Church of St. Dunstan may need extra checks for planning and heat loss before a heat pump is designed.

After we’ve gone
To keep the system working properly:
- Leave space around the outdoor unit
- Read the manufacturer’s warranty terms for your brand
- Store the MCS certificate and warranty documents together
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
