What air conditioning cannot fix
In fairness, some problems need a different answer:
- Stuffy rooms that need fresh air rather than cooling
- Work that needs permission from a landlord or the council
- Gas boiler or central heating faults (we don’t work on gas boilers)

Air con installers in Mottingham
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and our NICEIC approval means we install and certify it ourselves. For air conditioning in Mottingham, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork, wherever you are in Greater London.
In Mottingham, as across London, the rooms that get hottest are usually under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and the outside wall help us plan the work in Mottingham.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Dig out any previous service or F-Gas records
- Mention any managing agent or landlord rules we need to follow
- Clear a path to the units and the space around them
Getting a price
To get a fixed-price quote, ring us on 07833 053749 with the address and a few details about the rooms or units involved. Photos help a lot. We reply to enquiries the same working day.
Advice
After we’ve gone
Think of this as the after-treatment advice, short and simple:
- Wash or vacuum the filters as the manual describes
- Refit filters properly after cleaning
- Keep the F-Gas records, commissioning details and warranty information together
If anything is not right after we’ve gone, call us on the same number. Let us know what’s happening and any error code, and we’ll talk it through with you.
Set it and leave it. A moderate set temperature cools the room just as well as the lowest one, without the waste and keep doors and windows shut while it runs.
Mottingham questions
Can you do air conditioning in Mottingham?
Yes. We work across London and the South East from our base in East Grinstead, and Mottingham is part of that. To start, call us on 07833 053749 or use the quote form with a few photos.
Can I fit air conditioning in Mottingham without planning permission?
It depends on the property. The half-mile around the middle of Mottingham holds about 3 listed buildings and structures. 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 Lewisham council, which is typically the planning authority for Mottingham when it matters.
How long does air conditioning 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.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. An undersized unit never catches up, and an oversized one cycles and wastes energy, so we explain why we’ve chosen a particular output.
How quickly will you reply?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Can I have air conditioning in a flat?
Often, yes, but there are extra steps. You’ll usually need the landlord’s or management company’s consent for the outdoor unit and the pipe route, so check the lease. Permitted development rules for flats are also tighter than for houses, and we flag anything that may need permission. This is general information, not legal advice.
What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.

What an install looks like in Mottingham
About 48% of homes in and around Mottingham were built between the wars, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 41% of households in terraced houses. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. Terraces have little side access, so the outdoor unit typically goes on the rear wall or a flat roof, with the pipe run kept short. London installs often hinge on outside space, the lease and access to the building.
Close to Grove Park station? A small study or box room used for work can usually be cooled with a single indoor unit. Homes near Jubilee International Church are a good example of where we look up the heritage status of the building before fixing anything to it.

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.”
