Where we work around Wealdstone
Wealdstone sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
That includes premises in HA3 and the surrounding districts. We also cover Harrow, Pinner and Bushey, all within easy reach of Wealdstone.
In Wealdstone, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
If a system in Wealdstone is old and keeps failing, we will tell you honestly whether repair or replacement makes more sense.

Before you book in Wealdstone
Working hours
Most Wealdstone businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
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 Wealdstone 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.
FAQs for Wealdstone
How much does commercial air conditioning cost in Wealdstone?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in Wealdstone, 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 Harrow, Pinner and Bushey?
Yes. Alongside Wealdstone, we also cover Harrow, Pinner and Bushey. 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.
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?
