Commercial ventilation brings outdoor air into a building and removes stale air, using fans and ductwork to supply and extract air at the rates needed for the number of people and the activity.
Willesden and surrounding areas
Willesden sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
We work across Willesden's postcode districts, including NW10. Neighbouring towns we cover include Cricklewood, Notting Hill and Shepherds Bush. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

Points to plan for in Willesden
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
