Air source heat pumps in Wilmington
An air-to-water heat pump costs £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 the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. If the problem is planning and permitted development questions and questions about where the outdoor unit can go, we can sort it out.
Space for an outdoor unit is rarely an issue near Wilmington, so the design focuses on heat loss and radiators.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Looking after your system
Simple habits make a real difference. We recommend:
- Seal draughts where you can
- Know the servicing conditions in your warranty
- Keep the MCS certificate with the manufacturer’s paperwork
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
Your questions about air source heat pumps in Wilmington
Is Wilmington 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 I need planning permission for a heat pump in Wilmington?
There’s no single answer: the building and the outdoor unit position decide it. Central Wilmington is a short walk from the Wilmington Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where necessary, we check with the local planning authority (for Wilmington, typically Wealden council).
Will I get records for the system?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Am I eligible for a heat pump grant?
Quite possibly. The scheme runs in England and Wales and pays £7,500 towards an eligible air-to-water or ground source heat pump, or £2,500 for an air-to-air system that meets stricter conditions. Until March 2027 there’s an extra £1,500 for air source or ground source heat pumps in homes on oil or LPG with no mains gas. The survey is where we check your home against them.
How quickly will you reply?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
What owners can safely do
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
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 phone 07833 053749 or use the quote form.
What we do, step by step
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Visits to Wilmington are agreed with you in advance and planned so the job can be finished in one trip where possible.

Air source heat pumps in Wilmington: the local picture
Valuation Office Agency council tax records date about 45% of homes in Wilmington and the neighbourhoods around it to the post-war years, 1945 to 1972, and Census 2021 figures found about 70% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Older homes near St Mary and St Peter's Church may need extra checks for planning and heat loss before a heat pump is designed. Historic houses such as Alfriston Clergy House, about 1.9 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.
Wilmington is about 4 miles south-west of Hailsham, in East Sussex. Whatever kind of property you have in Wilmington, we can help with air source heat pumps.
