The licensing rules don’t change on the range, and our Brisbane electrician page explains them: the Electrical Safety Office issues the electrical contractor licence, and section 188 of the Electrical Safety Regulation 2026 says an electrical contractor’s advertisements must state the licensed or registered business name, that the contractor is licensed under the Act, and the contractor licence number. We put all three in the footer of each Toowoomba site we build. The same page covers the smoke alarm stage that reaches every remaining Queensland home on 1 January 2027.
The state lists two distributors: Energex for South East Queensland and Ergon Energy for all other areas, and Energex’s network stops at the foothills of the Toowoomba range. Toowoomba is on the Ergon side; down the range it changes. Energex finished a $12.3 million upgrade in 2014, upgrading the Glenore Grove substation and running a new line to the Laidley substation, which it said improved supply to more than 6,000 Lockyer Valley homes. The emergency lines differ too: 13 16 70 for fallen lines on Ergon’s network, 13 19 62 on Energex’s, and 000 whenever someone is in danger.
Rooftop solar is unusually dense here. When the state ranked postcodes by residential solar customers in September 2022, 4350 came fourth with more than 12,250 households, behind Bundaberg, Hervey Bay and Caloundra, and neighbouring 4352 came 33rd. That gives a storm page something specific to say. The Electrical Safety Office’s guidance is that a damaged solar or battery system should be inspected, repaired and checked by a licensed electrical contractor before it’s re-commissioned, because panels keep producing voltage in daylight even with the grid off, and that a storm-damaged property may need verification tests and a certificate of test before the distributor reconnects it.
The region is large and still growing. Toowoomba Regional Council covers about 12,957 km² and had an estimated 186,276 residents in June 2025, up 2,201 in a year; the Highfields area alone had 16,630. Winter shapes the work as well: at the Bureau of Meteorology’s Toowoomba Airport station, 641 metres up, July averages 16.8°C by day and 6.7°C overnight. On the commercial side, Toowoomba Wellcamp Airport opened in November 2014 beside the Toowoomba Bypass, between Charlton and Athol, and in 2019 the state reported $16.7 million of road, stormwater and utility works, including the Steger Road project, finished to open up the northern precinct of the Toowoomba Trade Gateway.
We’re an Adelaide team at Ste 3/110 Hutt St, and Toowoomba sites are handled by phone and email. You send your contractor licence number, the suburbs and towns you cover, whether that’s Highfields, Westbrook and Oakey or down to Laidley, and photos of switchboards and solar jobs; we send a draft link to check on your phone, and you pay once you’ve approved it.
