Air source heat pumps in Lambs Green
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler doesn’t qualify. The work covers underfloor heating, air-to-air heat pumps and hot water cylinders, and common reasons people get in touch are questions about listed buildings or conservation areas and no space for a hot water cylinder.
Older and listed homes in villages like Lambs Green need extra care, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Managing agents and facilities teams in Lambs Green
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
Running several properties is easier with one contractor. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
The process
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We agree a date with you and plan the visit to Lambs Green so we arrive with what’s needed.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Clear access to the fuse board
- Mention any roof access, ladders or high-level work
- Let us know if the building has a permit or sign-in process

- What kind of system it is
- The condition of any existing system
- Which make and model is being fitted or worked on
A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. You’ll have a fixed price before we start, and the quote sets out the VAT.
What we need to know
What to send for a quote:
- Wide photos of the room or the existing unit
- A photo of the consumer unit with the cover closed

Questions from Lambs Green
Is planning permission needed for a heat pump in Lambs Green?
It depends on the property. Around 4 listed entries sit within 0.5 miles of central Lambs Green. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Lambs Green, usually Horsham council).
Is the heat pump grant available in Lambs Green?
Yes, the scheme covers homes in England, including Lambs Green, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
What’s the price of a heat pump installation?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. The heat pump size, radiator changes and the cylinder decide where in that range you are, and air-to-air systems are priced after a survey.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays and any changes are in the quote.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Don’t block radiators or indoor units with furniture
- Keep to regular servicing
- Find out the grant position at the survey
Now and then in cold weather, the outdoor unit defrosts itself. You might see steam or hear the unit change note, and that’s normal.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside so keep it unobstructed.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
