What to think about in Welling
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
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.
Future use
Allow for growth in occupancy or IT load.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
