How the visit works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. Before a visit in Finchley, we ask where the van can stop and how we reach the outdoor unit.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Getting ready for the visit
- Dig out any previous service or F-Gas records
- Let us know where the consumer unit is
- Keep pets out of the rooms we are working in

Air conditioning for homes and businesses in Finchley
Single-room systems are typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £2,800–£4,500 + VAT and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, and commercial VRF systems are priced after a survey. When someone in Finchley asks us for air con, the first questions are normally price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
The outdoor unit position is the biggest single decision: we balance airflow, noise, the pipe run and access for future servicing.
In a London area like Finchley, many of the homes we are 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.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Rented and managed buildings
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Homes in Finchley and air conditioning
About 47% of homes across Finchley and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and about 57% of households live in flats, according to the 2021 Census. 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. London installs often hinge on outside space, the lease and access to the building.
With historic houses such as Heath Hall about 1.8 miles south, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Around St Paul's Finchley, a quick check of the listing and conservation maps is part of planning any install.
Finchley is about 6 miles north of City of Westminster, in Greater London. Whether you are in the middle of Finchley or further out, we cover air conditioning, from a single room to a whole building.

Our nearest recent job to Finchley was on East Hill, Wandsworth (SW18), about 10 miles south: installing a Daikin wall-mounted unit in the open-plan living area. Read more

Questions from Finchley
Can you fit air conditioning in a London flat in Finchley?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Will air conditioning in Finchley need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 7 buildings and structures within half a mile of the centre of Finchley. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Finchley, normally Barnet council).
Where does the outdoor unit go?
It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours and position can affect planning.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Is Finchley in your area?
Yes. Finchley is part of the area we cover, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
Do I need a new electrical circuit?
Most of the time. We check your consumer unit on the survey and include any electrical work on the quote and we install and certify the circuit as NICEIC approved contractors.

What else we do in Finchley
Owner checks or an engineer?
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
System by system
Outdoor unit positions
On flats and terraced houses, space outside is often the deciding factor. We look at walls, roofs, balconies and yards on the survey and we flag any consent you may need.
Electrical supply
We check the consumer unit on the survey, so the quote covers any electrical work needed. An older board may need extra work, and we explain why if so.
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.”
