Points to plan for in Barnet
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.
Conservation areas
Historic streets and listed buildings in and around Barnet are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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.
Leased premises
If your Barnet 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.
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 in Barnet
How much does commercial air conditioning cost in Barnet?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in Barnet, 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 East Barnet, Potters Bar and Borehamwood?
Yes. Alongside Barnet, we also cover East Barnet, Potters Bar and Borehamwood. Each has its own page with local guide prices.
Do you service systems you did not install?
Yes. We service most commercial makes and models; tell us the make and model if you know them.
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.
