Units need space in the ceiling void or a plant area with access for filter changes.
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.
Summer bypass
A bypass avoids warming incoming air in summer.
Access and parking
Town-centre jobs in Dartford often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
