Notifying the occupier prior to isolating circuits is crucial primarily for ensuring their safety and awareness. When circuits are isolated, occupants may be using electrical devices or may not be prepared for a sudden loss of power. By informing them in advance, you help prevent accidents or injuries that could occur if someone inadvertently attempts to use electrical equipment or expects power that is no longer available.

Additionally, this notification aids in building trust and maintaining a good relationship between the occupier and the electrical professional by keeping them informed about what to expect. Awareness of the work being done also allows occupiers to plan accordingly, whether that's to ensure their own safety or to account for any potential inconveniences during the isolation period.

While gaining consent, avoiding legal issues, and documenting the process are also important considerations in electrical work, the foremost priority must always be the safety and awareness of the individuals present in the environment.
