Air conditioning installation in Ham, Greater London
Looking for air conditioning in Ham? We diagnose first, fix the price and book the work around you, finishing with proper records.
- A portable unit with a hose out of the window
- Rooms that get too hot to sleep or work in
- Not knowing which system, size or brand to choose
Before you call an engineer
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call us on 07833 053749.
Air conditioning for homes and businesses in Ham
Good air conditioning starts with the right system in the right place. Each room is assessed for its size, windows, direction and how it’s used, and we agree the unit positions and the route for the pipes, cable and drain before you get a fixed-price quote. A lot of the calls we get from Ham are about one room that is too hot to sleep or work in. That’s typically a single wall-mounted split, from £1,200 + VAT.
Across London, and in Ham too, a lot of air conditioning goes into flats and terraces rather than detached 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 normally come into it, and we can give you the details they’ll ask for.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What an install looks like in Ham
Valuation Office Agency council tax records date about 63% of homes in Ham and the neighbourhoods around it to the post-war years, 1945 to 1972, and the 2021 Census found about 40% of households in terraced houses. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. Terraces have little side access, so the outdoor unit normally 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.
About 0.6 miles north stands Ham House. Listed homes in any area need consent first, so tell us if yours is one.
Ham is about 1 mile south-east of Twickenham, in Greater London. Our engineers cover Ham for air conditioning and across the rest of Greater London. Across Greater London, we cover 764 places, and Ham is one of them. There’s also a page for London, about 10 miles away.
Our nearest recent job to Ham was on Richmond Hill, Richmond (TW10), about 1 mile north: installing a Mitsubishi Electric Zubadan multi-split system serving four bedrooms, the study and the living room: six indoor units in total. Read more

Honest limits
Not every problem is solved by air conditioning, and we’ll tell you before work begins. It will not put right:
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Work that needs permission from a landlord or the council
- Draughts and missing insulation
Not sure which it is? You can call us on 07833 053749, or email if that’s easier and we will tell you honestly.

FAQs for Ham
Do I need planning permission for air conditioning in Ham?
It comes down to the building and the spot chosen for the outdoor unit. Central Ham sits inside the Ham Common Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the local planning authority (for Ham, normally Richmond-Upon-Thames council).
Do I need permission to put air conditioning in my flat in Ham?
Often, yes, but the lease and the freeholder typically have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
How long does it take to fit air conditioning?
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.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Is air conditioning possible in a flat?
In many cases, but permissions come first. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls, so check the lease. Planning rules for flats are tighter too, and we flag anything that may need permission. This is general information, not legal advice.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What we’re called out for in Ham
Rooms in the roof are often the hardest to keep cool. The roof takes the full force of the sun, and warm air rises from the floors below, so a bedroom or office under the roof can stay warm well into the night.
Any of these is worth a proper look:
- Rooms heated by plug-in heaters
- Working from home in a room that gets too warm
- A room that is unbearable on warm days
Around Ham Christian Centre, a quick check of the listing and conservation maps is part of planning any install.

What else we do in Ham
The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. A few pictures of the room, the outside wall and the fuse board help us plan a job in Ham.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure someone can let us in at the agreed time
- Mention any parking restrictions near the property
How to get a quote
Quotes don’t take long. Send a few details and photos, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
