How we handle air conditioning in Lions Green
Good air conditioning starts with the right system in the right place. We look at each room’s size, glazing, orientation and use, then agree where the indoor and outdoor units go and how the pipework, cable and condensate drain will run before you get a fixed-price quote. Air con, air conditioning, a split system: whatever you call it, in Lions Green it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
In a village like Lions Green, many homes are older, and some are listed. We check that first, because permitted development does not apply within the grounds of a listed building.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

What we do, step by step
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can usually work room by room or zone by zone. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Work in Lions Green is booked in advance at a time that suits you.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any parking restrictions near the property
- Keep pets and children away from the work area
Get a fixed-price quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.

Lions Green questions
Can I fit air conditioning in Lions Green without planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 5 listed entries sit within 0.5 miles of central Lions Green. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Lions Green, usually Wealden council).
Do you cover smaller places like Lions Green?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
How long will the installation take?
A single-room system is normally fitted in a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Can I use air conditioning to heat a room?
Most of the time, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
What size air conditioning unit do I need?
It depends on the room, not only its floor area. Windows, the direction the room faces, the roof above and the people and equipment in it all count, and we take them all into account on the survey.
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.

Why act early in Lions Green
Planning ahead beats a rushed decision in a heatwave. When people buy in a hurry, the unit is often the wrong size or badly placed, which is costly to undo. Booking the survey early gives you time to weigh up the options. For a village like Lions Green, booking ahead lets us plan the trip properly.
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we will explain each part.

When it’s something else
To be straight with you, there are a few things this work will not fix:
- Building damp that has a structural cause
- Draughts and missing insulation
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
Not sure which it is? You can give us a ring on 07833 053749 or fill in the contact form and we will tell you honestly.

Managing agents and facilities teams in Lions Green
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.
Homes in Lions Green and air conditioning
The 2021 Census found about 80% of households in detached or semi-detached houses. Houses normally have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
About 4 miles south stands Horselunges Manor. Listed homes in any area need consent first, so tell us if yours is one. Homes near The Parish Church of All Saints are a good example of where we look up the heritage status of the building before fixing anything to it.
