Your questions about air source heat pumps in Debden Green
Is a heat pump in Debden Green permitted development?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 6 buildings and structures within half a mile of the centre of Debden Green. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Uttlesford council, which is normally the planning authority for Debden Green.
Is Debden Green within the area you cover?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is there VAT on a heat pump?
Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. Hotels and businesses pay the standard rate. Please treat this as general information, not tax advice.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and we hold it.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
How we handle air source heat pumps in Debden Green
For an air-to-water heat pump, the price is £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. If the problem is finding a place for the outdoor unit and a boiler that’s getting old, we can help.
Space for an outdoor unit is rarely an issue near Debden Green, so the design focuses on heat loss and radiators.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

What the work involves, system by system
Hot water cylinders
An older cylinder may not suit a heat pump and we tell you if it needs replacing.
Air-to-air heat pumps
Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. Hot water needs a separate source so you’ll need another way to heat it.
Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Check eligibility for the Boiler Upgrade Scheme early
- Look at insulation alongside the heat pump
- Keep to regular servicing
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Heat pumps prefer steady, low-temperature running as explained at handover.
