Things to check in Hatfield
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Working hours
Most Hatfield businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
