Air conditioning around Charlton
Census 2021 figures found about 53% of households live in flats. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. London installs often hinge on outside space, the lease and access to the building.
Homes near St Catherine Labouré are a good example of where we look up the heritage status of the building before fixing anything to it. Queen's House (roughly 1.9 miles west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
Charlton is about 2 miles west of Plumstead, in Greater London. Whatever kind of property you have in Charlton, our engineers can help with air conditioning.

Air conditioning in Charlton, done properly
Good air conditioning starts with the right system in the right place. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain, all before the price is fixed. Most split systems we fit in Charlton are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.
New circuits are done by our NICEIC approved electricians, so there’s no separate electrician or building control visit to arrange.
In a London area like Charlton, many of the homes we’re asked about are flats, maisonettes and terraced houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder usually come into it, so we write up the proposed positions for them to see.
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. That also helps where the warranty terms ask for regular servicing.

Your questions about air conditioning in Charlton
Will air conditioning in Charlton need planning permission?
It depends on the property. The centre of Charlton is in a conservation area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Greenwich council, usually the authority for Charlton when it matters.
Can you fit air conditioning in a London flat in Charlton?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Does air conditioning need its own electrical supply?
Most of the time, yes: a dedicated circuit is needed. Under Part P, a new circuit has to be notified unless a registered competent person does it, and we are NICEIC approved, so we can install and certify it.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Keep every service record either way.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.

What else we do in Charlton
System by system
Wall-mounted split systems
Wall-mounted units suit bedrooms, living rooms, home offices and small commercial rooms. The unit goes where it spreads the air well and the filters are easy to reach, and away from where the air would blow straight onto people.
Ceiling cassettes
Cassettes need space above the ceiling and a route for the condensate, and many use a built-in condensate pump to lift the water away. We check the ceiling void on the survey.
When it’s something else
Some problems need a different service or another trade:
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Draughts and missing insulation
- Work that needs permission from a landlord or the council
If in doubt, phone 07833 053749 or use the quote form and we will say what we think before booking.

How the visit works
Think of the visit in three stages: diagnose, treat 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 about a day for a single-room system, longer for multi-room and ducted systems. Parking bays, permits and roof or balcony access are the first things we ask about in Charlton.
- 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.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Move furniture away from the wall where we will be working
- Let us know where the consumer unit is
- Keep pets and children away from the work area

Pricing air conditioning in Charlton
We quote each job individually. These are the things that affect it:
- What we find on the survey or diagnosis
- One-off work versus a regular service cycle
- Whether the existing supply is suitable
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll explain each part.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Your installation or service records
- The outdoor side of the property, including any roof or flat area
- The remote or wall controller showing any error
Photos are enough for some jobs; others need a visit first. 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.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
