Greater London · Air conditioning installation
Air conditioning installation in Custom House, Greater London
For air conditioning in Custom House, one call is all it takes: diagnosis, fixed price, work and sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- A study or office that overheats during the day
- A portable unit with a hose out of the window
- A system on old refrigerant that’s due for replacement
Keeping the system healthy
Looking after the system is mostly common sense. Our tips:
- File the paperwork with the manual
- Wash or vacuum the filters as the manual describes
- Keep to the service interval the manufacturer recommends
We clear up before we go: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Outside, the pipework is neatly fixed and protected as agreed on the survey.
Don’t ignore small changes. A drip, a noise or a flashing light is often an early sign of a fault, and early repairs are typically simpler.

Not sure what you need, or where it would go? Send a few pictures of the rooms and the outside walls when you phone 07833 053749 or drop us a line, and you’ll hear back from us the same working day to arrange a survey or a quote. People searching for “air con near me” in Custom House want two things: a sensible price and someone qualified. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Across London, and in Custom House too, a lot of air conditioning goes into flats and terraces rather than detached houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, and we can give you the details they’ll ask for.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
Air conditioning in Custom House: the local picture
About 64% of homes in the Custom House area have been built since 2000, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 76% of households live in flats. Newer homes normally have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. London installs often hinge on outside space, the lease and access to the building.
Plenty of people near Custom House station split the week between the train and a spare room, and that spare room is often the first to get a unit. With historic houses such as Queen's House about 2.3 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Custom House: your questions answered
Do I need permission to put air conditioning in my flat in Custom House?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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.
Is Custom House in your area for air conditioning?
We do: Custom House falls inside our working area. Just phone us on 07833 053749 or send an email with a few details.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
How do I know what size unit to get?
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 the survey covers each of them.
Which type of air conditioning is best?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone and we’ll gladly show you ours.
Will I get records for the system?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.

- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
