Commercial air conditioning in London
We design, install, service and repair commercial air conditioning and ventilation across London, and handle the F-gas leak checks and TM44 inspections larger systems need.
Typical prices in London: a single split from £1,850 installed and a service visit from £225 for the first indoor unit, both plus VAT.
Covering London and nearby
We cover all of London, including Brent, Islington, Bexley, Barking and Sutton. Wherever your premises are, the survey, quote and installation follow the same steps.
Postcode districts we cover include BR1, E16, EN5, N16, SE7, SW8, W1 and WC2R.
In London we work with offices, shops and hospitality premises, from a single room to a whole floor; each job starts with a heat load check rather than a guess from the floor area.
Service and repair visits in London are booked around your opening hours, with the price agreed before we come.

Before you book in London
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Conservation areas
Historic streets and listed buildings in and around London are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Access and parking
Town-centre jobs in London often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
Questions from businesses in London
How much does commercial air conditioning cost in London?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in London, and a ceiling cassette £2,750–£6,350 per unit. A small shop or office with two to four indoor units usually comes to £6,350–£20,995 plus VAT.
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.
Which refrigerant do new systems use?
Most new small split systems use R32, because new single splits under 3 kg in Great Britain cannot use refrigerants with a GWP of 750 or more. Larger systems vary by equipment.
Do you handle landlord consent?
We supply the drawings, unit data sheets and method of fixing your landlord or managing agent will ask for.
Is the survey free?
Yes, for new installations and replacements on the UK mainland. Service, repair and inspection visits are priced before we book them.
