How we handle air source heat pumps in Plumpton
We install air source heat pumps in Plumpton and across East Sussex, and we are MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We’ll explain which type fits your home and why. If you’re dealing with replacing a combi boiler with a heat pump and questions about listed buildings or conservation areas, we can help.
Older and listed homes in villages like Plumpton need extra care, and permitted development doesn’t cover listed buildings, so consent comes first.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Looking after your system
Aftercare is straightforward, and it helps at the next service:
- Leave indoor units unobstructed
- Book a yearly service
- Clear leaves and debris from the outdoor unit
Now and then in cold weather, the outdoor unit defrosts itself. You might see steam or hear the unit change note and it’s part of how the system works.
Heat pumps prefer steady, low-temperature running as explained at handover.
FAQs for Plumpton
Do you cover smaller places like Plumpton?
Yes. Plumpton is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Can I fit a heat pump in Plumpton without planning permission?
It depends on the property. Historic England lists about 12 buildings and structures within half a mile of the centre of Plumpton. 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 can’t face a road. Where needed, we check with the local planning authority (for Plumpton, typically Lewes council).
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
How soon will you get back to me?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
Am I eligible for a heat pump grant?
That depends on the scheme conditions, which we check for you. As the installer, we make the application where you qualify.

Homes in Plumpton and heat pumps
About 76% 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.
Period properties close to The Parish Church of St Michael and All Angels can suit a heat pump, though insulation and any heritage protection are checked first. With Anne of Cleves House about 4 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump.

How the visit works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. For a village like Plumpton, tell us about narrow lanes, gates and parking when you book.

Heat loss surveys
A heat loss survey measures how much heat each room loses on a cold day. It’s the basis for sizing the heat pump and the radiators.
Air-to-air heat pumps
The £2,500 grant for air-to-air applies only when the system replaces the fossil-fuel heating and covers the whole home’s demand. It also has to be fitted by an MCS certified installer, in a home.
A customer’s words
“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.”
