Barnes and surrounding areas
Premises in Barnes are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.
We work across Barnes's postcode districts, including SW13. Nearby, we also cover Chiswick (about 2 km), Putney (about 3 km) and Fulham (about 3 km). In Barnes, 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.

What to think about in Barnes
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Working hours
Most Barnes businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
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.
