Local points to consider
Leased premises
If your Willesden 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.
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.
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 Willesden are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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 Willesden
How much does commercial air conditioning cost in Willesden?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in Willesden, 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 Cricklewood, Notting Hill and Shepherds Bush?
Yes. Alongside Willesden, we also cover Cricklewood, Notting Hill and Shepherds Bush. Each has its own page with local guide prices.
Can you work outside our opening hours?
Yes. Early starts, evenings and weekends can be arranged, and any extra cost is shown in the quote.
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.
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.
