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