HV (high voltage) isolation request

To get approval for a high voltage isolation request you’ll need information detailing the purpose for the isolation and any prescribed works being undertaken by a Registered Electrical Contractor.

The planning of switching instructions to isolate work is a complex process which requires coordination across our network control centre and all teams active in the vicinity of the planned works.

Please allow a minimum of 40 days for the isolation to be arranged once we have accepted your request and payment is received.
