How the job changes from property to property
Electrical supply
The fuse board is looked at during the survey, so the quote covers any electrical work needed. Older boards sometimes need more work to take a new circuit and we’ll tell you if yours does.
Ceiling cassettes
Cassettes are good at even airflow across a large floor area, and the slim grille sits neatly in the ceiling.

Greatness: your questions answered
Can I fit air conditioning in Greatness without planning permission?
It depends on the property. Central Greatness sits inside a conservation area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Greatness, typically Sevenoaks council).
Do you cover Greatness for air conditioning?
Yes, Greatness is within the area we cover. Get in touch with the details and we reply the same working day.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Is air conditioning possible in a flat?
In many cases, but permissions come first. You will usually need the landlord’s or management company’s consent for the outdoor unit and the pipe route and the lease will say. Permitted development rules for flats are also tighter than for houses, so we point out anything that may need permission on the survey. This is general information, not legal advice.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access, and we tell you how long on the quote.

If your home is in one of the older streets near St John the Baptist, it’s worth checking whether it’s listed or in a conservation area before an install. Knole House (roughly 1.7 miles south) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Fixed-price quotes for air conditioning in Greatness
The survey or diagnosis tells us what the work involves. We look at:
- Access, including height, roofs and ladders
- What we find on the survey or diagnosis
- What kind of system it is
Typical ranges are on our prices page, but your price depends on the job in front of us. For a fixed-price quote, call us on 07833 053749, or email if that’s easier, and we’ll talk you through it.
Asking for a quote
Good photos often save a visit. Try to include:
- Photos showing the indoor unit and the space around it
- Where the outdoor unit is, or where you’d like it
- Any previous service or F-Gas records
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, you get a fixed price before any work is booked.
Honest limits
In fairness, there are a few things this work won’t fix:
- Gas boiler or central heating faults (we don’t work on gas boilers)
- Draughts and missing insulation
- Building damp that has a structural cause
If you’re not sure, just ring 07833 053749 or drop us a line and we will give you a straight answer.

How it works
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Send pictures of the space and the outside wall, and we can plan the work near Greatness.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- 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.
Getting ready for the visit
- Clear access to the fuse board
- Move furniture away from the wall where we’ll be working
- Make sure we can reach the outdoor unit, or where it will go
