Heat pump installation in Greensted, Essex
Air source heat pumps across Greensted and nearby, from a site survey or diagnosis to sign-off and a fixed price agreed before any work starts.
- Choosing between air-to-water and air-to-air
- Radiators that may be too small for a heat pump
- Deciding on the outdoor unit position
What you can do yourself, and what needs us
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Air source heat pumps in Greensted, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers underfloor heating, radiator systems and homes heated by oil, LPG or gas, and people most often call us about working out where a cylinder could go and a boiler that’s getting old.
For a home around Greensted that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Air source heat pumps in Greensted: the local picture
The Valuation Office Agency’s council tax figures date about 44% of homes in Greensted and the neighbourhoods around it to the post-war years, 1945 to 1972, and the 2021 Census found about 68% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Older homes near Greensted Church may need extra checks for planning and heat loss before a heat pump is designed. With Hill Hall about 3.8 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump.
Greensted is about 5 miles east of Epping, in Essex. Greensted gets the same approach as every job we take on: diagnosis first, a fixed price and proper paperwork when we’ve finished.

Leave it or put it right?
A sudden boiler failure rarely leaves room to plan a heat pump properly. Surveying and designing in advance means the system is sized right and any grant is applied for before you need the heat. Getting the date in early helps for a place like Greensted.
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote and give you a fixed price before we start.

How the visit works
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the trip to Greensted around you.
- We find out about your home and the heating you have now.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Keep pets out of the rooms we are working in
- Make sure we can reach the consumer unit or fuse board
How to get a quote
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price so you know the cost before we begin.

Common questions in Greensted
Will you come out to Greensted?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is a heat pump in Greensted permitted development?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Greensted holds about 7 listed buildings and structures. 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 do not 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 Greensted, usually Epping Forest council).
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
