Local points to consider
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most Enfield businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
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.
