Air source heat pumps in Coxtie Green
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. If you’re dealing with not knowing whether a grant applies and checking whether planning permission is needed, we can help.
In a place like Coxtie Green, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

When to call us in Coxtie Green
Homes with electric heating sometimes look at heat pumps as an alternative. The survey tells you whether it’s practical and what’s involved along with whether any grant could apply.
Customers normally contact us when they notice one of these:
- Comparing heat pump types
- Questions about listed buildings or conservation areas
- Finding a place for the outdoor unit
If your home is listed, like Hare Hall about 4.3 miles south-west, listed building consent comes before any heat pump work.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether the quote is a fixed price
- What paperwork you will receive afterwards
Coxtie Green: your questions answered
Is a heat pump in Coxtie Green permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Around 8 listed entries sit within 0.5 miles of central Coxtie 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 the local planning authority (for Coxtie Green, usually Brentwood council).
Will you come out to Coxtie Green?
Yes. Coxtie Green is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water and the survey helps decide.
How do you keep the place clean during the work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Do I get paperwork after the visit?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
How much VAT is charged on a heat pump in a home?
Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. The relief doesn’t cover businesses. Please treat this as general information, not tax advice.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
What a heat pump looks like in Coxtie Green
About 47% of homes in Coxtie Green and the neighbourhoods around it date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 76% of households live in detached or semi-detached houses, according to the last census (2021). Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Older homes near Trinity Church may need extra checks for planning and heat loss before a heat pump is designed.

How the visit works
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. A note on how to find the property and where to park makes a visit to Coxtie Green easier.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Make sure we can reach the consumer unit or fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
How to get a quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
