Your questions about air source heat pumps in Crow Green
Will you come out to Crow Green?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will a heat pump in Crow Green need planning permission?
It depends on the property. Around 3 listed entries sit within 0.5 miles of central Crow Green. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Crow Green, normally Brentwood council) first.
Will my radiators work with a heat pump?
Some radiators may be fine as they are, and some may need to be larger. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.
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, and this is not tax advice.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
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. With air-to-air, hot water needs another source, and we explain which suits your home.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How we handle air source heat pumps in Crow Green
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you will need another way to do that. We are often asked to deal with deciding on the outdoor unit position and wanting to stop using oil, LPG or gas for heating, across homes heated by oil, LPG or gas, hot water cylinders and radiator systems.
Space for an outdoor unit is rarely an issue near Crow Green, so the design focuses on heat loss and radiators.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Fixed-price quotes for air source heat pumps in Crow Green
We quote each job individually. These are the things that affect it:
- The size of the job
- The equipment or parts the job needs
- Access, including height, roofs and ladders
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
Before you ask for a quote, gather:
- The postcode and whether it’s a home, flat or business
- A photo of the consumer unit with the cover closed
- The remote or wall controller showing any error
Quotes do not take long. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
Landlords, agents and facilities managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.
Homes in Crow Green and heat pumps
The Valuation Office Agency’s council tax figures date about 50% of homes across Crow Green and its surrounding area to the post-war years, 1945 to 1972. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period.
If your home is one of the older properties near Trinity Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Historic houses such as Ingatestone Hall, about 4.4 miles east, are a reminder that listed homes need consent before a heat pump goes in.

Leave it or put it right?
For eligible off-gas homes on oil or LPG, an extra £1,500 is on offer until March 2027. If that applies to you, it’s worth asking about sooner rather than later. Waiting rarely makes an air conditioning problem smaller.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the existing unit help with repairs and servicing in Crow Green.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Getting ready for the visit
- Mention any roof access, ladders or high-level work
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit
How to get a quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
