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.
Working hours
Most Catford businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
