Commercial premises are more likely than domestic premises to use lighting which makes a significant change to a building. It may therefore be subject to planning permission.
Premises or apparatus used for the provision of electronic communication services need adequate lighting for operation and security purposes, to ensure the safety of their staff, and to protect the integrity of the telecommunications network. Nuisance law recognises the need for industry to be able to carry out its usual functions without being compromised by inadequate security lighting. That need is protected by the defence of 'best practicable means'.
