Things to check in Bexley
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Leased premises
If your Bexley premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Coordination
Ceiling, lighting, sprinkler and electrical layouts are coordinated early.
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.
