We’re based in East Grinstead and cover London and the South East, as an F-Gas certified company with NICEIC approval.
London homes in Holloway can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and we plan the pipe route so it’s as short and tidy as the building allows.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Why act early in Holloway
New systems now use lower-impact refrigerants. Since 2025, new single split systems with less than 3 kg of refrigerant can’t use F gases with a GWP above 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Approvals for flats in Holloway can take longer than the install itself.
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.

Your questions about air conditioning in Holloway
Can I have air conditioning in a flat in Holloway?
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.
Is air conditioning in Holloway permitted development?
It depends on the property. Central Holloway sits inside a conservation area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Islington council, which is normally the planning authority for Holloway.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
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.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
What else we do in Holloway
Different systems, different jobs
Multi-split systems
A multi-split runs several indoor units from one outdoor unit. It saves wall space outside and suits homes where several rooms need cooling and each indoor unit has its own controls.
Electrical supply
We check the consumer unit on the survey, so the quote covers any electrical work needed. Older boards sometimes need more work to take a new circuit, and we explain why if so.
Homes in Holloway and air conditioning
VOA council tax data put about 52% of homes across Holloway and its surrounding area before 1919, and about 82% of households live in flats, according to Census 2021 figures. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Close to Drayton Park station? A small study or box room used for work can normally be cooled with a single indoor unit. Around St Joseph and St Padarn's Church, a quick check of the listing and conservation maps is part of planning any install.

What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What we do, step by step
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. In a London area like Holloway, parking and access are worth sorting out before the day.
- 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.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Mention any parking restrictions near the property
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a price
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.
