Before you book in Winchester
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
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.
Future use
Allow for growth in occupancy or IT load.
Access and parking
Town-centre jobs in Winchester 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.
