About our air source heat pumps in Heathfield
A £2,500 grant is available for some air-to-air heat pumps, with conditions. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home; adding it alongside a boiler does not qualify. The work covers hot water cylinders, underfloor heating and radiator systems, and the jobs we see most are questions about the Boiler Upgrade Scheme and replacing a combi boiler with a heat pump.
For a house near Heathfield, space outside is rarely the problem, so heat loss, radiators and the electrics are what we check.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What you can do yourself, and what needs us
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call 07833 053749 or fill in the contact form.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Heathfield questions
Will you come out to Heathfield?
Yes. Heathfield is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is the heat pump grant available in Heathfield?
Heathfield is in England, where the Boiler Upgrade Scheme runs. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Heathfield and across East Sussex. Let us know who the records should go to.
How much does an air source heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.
Do you protect the property while you work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.

Why act early in Heathfield
Getting the sizing wrong causes problems that are hard to fix later. Doing the survey properly from the start avoids that. Dealing with it now is normally simpler than a breakdown later.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you’re unsure, phone 07833 053749 or email us for straight advice and a fixed price.

What a heat pump looks like in Heathfield
About 69% of households live in detached or semi-detached houses, according to the 2021 Census. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder. Historic England lists about 5 buildings and structures within half a mile of the centre of Heathfield, including The Gibraltar Tower (grade II*). Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Wealden council) before the heat pump design is finished.
Every heat pump design starts with a room-by-room heat loss calculation. Live in one of the older houses around St Richards Church? Expect the survey to look closely at heat loss and at the building’s planning status.

Advice
System by system
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
Heat loss surveys
The survey works out the heat needed room by room. Everything else is sized from it.
