Zak and Ryan did a amazing job. Even with the obstacles of a double story home with a internal switch board they persevered in the heat and got the job done. Thanks guys we realy appreciate your work and polite attitude.

We assess the network, asset condition, records, access, isolation requirements and available outage window before setting the scope. The quote covers the agreed switching, testing, maintenance or installation work and documentation. For substations, transformers, private high voltage networks and outage planning, see the full detail on high voltage and substation works.
With roughly 1830 residents per square kilometre, Croydon South has a small number of customer-owned substations, and their maintenance records are often incomplete. Croydon South is about 130 metres above sea level, with sites where access for plant is workable but needs checking before the day.
Croydon South sits about 29 kilometres out in Maroondah. Capacity for expansion is a common reason for an assessment. Croydon South is in Maroondah. High voltage work is governed by the electrical safety regime and the distributor's requirements, not by council. Access permits for work on public land are the exception.
Being next to Bayswater North and Croydon means Croydon South is almost never a standalone trip for our crew. Croydon South spans roughly 2.6 square kilometres of Maroondah. Postcode 3136, and 4759 people at the 2021 census.
For what it is worth on site: Croydon South Post Office opened on 1 February 1961 as the suburb was developed. Development era predicts the age of the asset and whether any maintenance history exists for it. Croydon South sits inside a block we cover properly rather than occasionally. The neighbouring suburbs on that run are Bayswater North, Croydon, Kilsyth and Ringwood East.
Croydon South is around 5.2 kilometres north of our workshop in Boronia, close enough that the van is stocked for the job before it leaves.

No travel charge applies. At around 5.2 kilometres north of our Boronia base, Croydon South is standard territory, and the call-out plus the first half hour is quoted up front.
Bayswater North, Croydon, Kilsyth and Ringwood East are all part of the same patch as Croydon South. If we are at one, we are minutes from the others.
Croydon South is in Maroondah (3136). Council approval is not part of a standard job, and we will tell you plainly if your property is the exception.
Only authorised HV operators working to a documented switching schedule. That authorisation and the paperwork behind it is a legal requirement, not a formality.
Tell us about the site, asset and required outage window. We’ll assess the records, access and switching requirements, then provide a clear project scope. Book an assessment or call our Boronia crew to discuss the work.
