Things to check in Leatherhead
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.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
