What's Involved in Permanently Disconnecting Power From a Property in Sydney?

What's involved in permanently disconnecting power from a property in Sydney? Unlike a temporary disconnection, where your connection points stay intact while supply is isolated, a permanent disconnection means the service line, meter and service fuse are physically removed because the site will no longer have an active connection. Ausgrid and Endeavour Energy both advise a minimum of 20 business days to process a permanent disconnection application once lodged, so this is not a same week job, and councils generally require proof of disconnection before issuing a demolition permit.

1. Permanent versus temporary disconnection: the real difference

Our guide to temporary disconnection before demolition and renovation covers the more common scenario, where a property is being rebuilt and the existing connection points need to stay intact for reconnection later. Permanent disconnection is a different service entirely: the service line and meter are physically removed rather than isolated, because the site will no longer have an active connection at all. Demolishing a structure with a live electrical connection still in place is a serious safety hazard and a breach of the NSW Service and Installation Rules, which is exactly why this distinction matters.

2. When you actually need a permanent disconnection

This service comes up most often for a final demolition with no rebuild planned, a vacant block being sold or held as land only, consolidating two titles and two meters into one, or any site where the owner genuinely does not want an active electrical connection going forward. It is a different job to a renovation disconnect and reconnect, and planning for the right one from the start avoids paying for reconnection infrastructure you do not actually need.

3. What the process actually involves

The process starts with a free site assessment of the existing overhead or underground supply, followed by a network application lodged with Ausgrid or Endeavour Energy. Dial Before You Dig confirms the location of underground services before any physical work begins, and the service line, meter and service fuse are then removed, with remaining conductors made safe at the point of attachment ahead of demolition works. A Certificate of Compliance for Electrical Work is issued once everything is finished, which is the document council and your insurer will want to see.

4. Planning around the 20 business day network timeframe

Both Ausgrid and Endeavour Energy advise a minimum of 20 business days to process a permanent disconnection application once it is lodged, which is considerably longer than most people expect for what sounds like a simple job. If a demolition date is already locked in with a builder, lodging the permanent disconnection application early, well before the physical demolition is scheduled, avoids a costly delay waiting on network approval at the exact moment the rest of the project is ready to proceed.

5. Why council and your insurer both care about this

Councils generally require proof of disconnection before issuing a demolition permit, since a live electrical connection on a demolition site is a genuine safety hazard for the demolition crew and anyone nearby. Insurers may also deny claims connected to a site where services were still live during demolition, so the Certificate of Compliance issued at the end of a permanent disconnection is worth keeping on file, not just handing straight to the builder.

Why it's Level 2 ASP work

Lodging a permanent disconnection application and physically removing the service line, meter and service fuse at the point of connection is contestable work that sits with an accredited Level 2 ASP, authorised by Ausgrid and Endeavour Energy to carry out this work. High Demand Electrical handles the entire process, from the network application through to the final compliance certificate.
