How a job in London works
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go. For sites in London we confirm access and parking beforehand.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.
Before you book in London
Power
Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Landlord consent
Most commercial leases need the landlord's written consent before external units or wall penetrations go in. We can provide drawings and unit data sheets for the request.
Leased premises
If your London premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Premises we work in around London
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
Common questions from businesses in London
How much does commercial air conditioning installation cost in London?
Guide prices in London run from about £2,500 to £6,095 per indoor unit (zone), plus VAT. A typical job (small shop or office, 2–4 indoor units) costs £6,350–£20,995 plus VAT. We fix the price in writing after a free survey.
Do you also cover Surrey, Hertfordshire and Essex?
Yes. Alongside London, we also cover Surrey, Hertfordshire and Essex. Each has its own page with local guide prices.
Will the system heat as well as cool?
Almost all modern commercial air conditioning is a heat pump that can heat as well as cool. Many businesses use it as their main heating in spring and autumn.
Do I need planning permission?
It depends on where the outdoor unit goes and the building. Units on a rear flat roof are often straightforward; front elevations, conservation areas and listed buildings usually need consent. We flag this at survey.
