Local points to consider
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.
Access and parking
Town-centre jobs in Isleworth 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.
Leased premises
If your Isleworth 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.
Conservation areas
Historic streets and listed buildings in and around Isleworth 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.
FAQs for Isleworth
How much does commercial air conditioning cost in Isleworth?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in Isleworth, 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 Hounslow, Heston and Richmond?
Yes. Alongside Isleworth, we also cover Hounslow, Heston and Richmond. Each has its own page with local guide prices.
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.
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.
