Harlesden questions
Do I need permission to put air conditioning in my flat in Harlesden?
Normally, 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 air conditioning in Harlesden permitted development?
It depends on the property. A conservation area takes in the middle of Harlesden. 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 Brent council, which is normally the planning authority for Harlesden.
Are you F-Gas certified?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas 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.
How much does air conditioning installation cost?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Long pipe runs, difficult access, a new circuit and premium indoor units push the price up, while commercial systems are priced after a survey.

In a London area like Harlesden, many of the homes we’re asked about are flats, maisonettes and terraced houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. In a flat, the lease and the freeholder normally come into it, and we can give you the details they’ll ask for.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

How the job changes from property to property
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, which the condensate drain takes away. If gravity won’t do it, a condensate pump is fitted, and we plan that on the survey.
Offices, shops and commercial rooms
Offices and shops usually need several units and sensible central controls. We size for the people, equipment and glazing in the space and we plan the installation around your opening hours where we can.
Managing agents and facilities teams in Harlesden
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
What happens on the day
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Send us a few phone photos and we can often price a straightforward job in Harlesden before visiting.
- You send pictures, or we visit and survey the rooms and outside.
- 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.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
How to prepare
- Let us know if the building has a permit or sign-in process
- Keep pets out of the rooms we’re working in
- Make sure we can reach the consumer unit or fuse board
Getting a quote
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.

What owners can safely do
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.

Air conditioning in Harlesden: local notes
The Valuation Office Agency’s council tax figures put about 52% of homes in and around Harlesden before 1919, and about 74% of households live in flats, according to the last census (2021). Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder typically decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
Homes near Church of All Souls are a good example of where we look up the heritage status of the building before fixing anything to it. Plenty of people near Willesden Junction station split the week between the train and a spare room, and that spare room is often the first to get a unit.
