The Electrical Safety Act 2022 and the Electrical Safety Regulations 2024 took effect on 1 July 2024. The old Electrical Workers and Contractors Licensing Board was abolished, and licensing moved to the Electrical Safety Regulator within NT WorkSafe. Electrical work licences are either unrestricted, as an electrical mechanic or an electrical mechanic and fitter, or restricted to the work named in an endorsement, such as air-conditioning and refrigeration equipment or disconnecting and reconnecting water heaters. A business needs an electrical contractor licence if it performs electrical work, contracts for it, employs people to do it for others, or advertises that it does it. The licence must name at least one nominated person who has held an unrestricted licence for two years or more and completed the approved contractor course, the business must carry at least five million dollars of public and products liability insurance, and the licence runs for up to three years. The Regulator keeps a register of licences. Builders and plumbers answer to separate boards, which our Darwin tradies page covers; how any rule applies to your own licence is a question for NT WorkSafe.
Under section 41 of the Act, whoever does the work completes a certificate of compliance stating it was tested safe and complies with the Act and the prescribed standards. A copy goes to the owner and occupier, to the person who ordered the work, to the Electrical Safety Regulator and, for network work such as a connection, to the network operator, and whoever completes it keeps it for at least five years. Before connecting a property to the network or disconnecting it, altering the network or isolating equipment from it, the licence holder has to notify the operator and get approval. In Greater Darwin that operator is Power and Water Corporation, owned by the Territory Government, which runs the northern network from Darwin to south of Katherine. For a new solar system, Jacana Energy tells its customers they need an approved connection agreement with Power and Water, and to ask Jacana to set the meter up for solar; its feed-in tariff covers systems under 30 kVA. A solar page that sets out those steps saves the customer a round of phone calls.
The rules that started applying on 1 July 2026 mostly change how installations are done. An indoor battery under the same roof as a habitable room needs the interconnected smoke alarm, low free-standing solar arrays need an enclosure, and EV chargers installed inside a building need the ceiling smoke alarm and switchboard sign. Freestanding chargers need a physical barrier against vehicles, and chargers inside apartment blocks and commercial buildings need EV signs at each vehicle entrance. Other battery rules were already in place, including a risk assessment before the work and installation to AS/NZS 5139, and every solar array has to meet the wind-action standard and the Building Code's requirements for high-wind areas. Some changes for owners, occupiers, landlords and property managers that were due the same day have not started, after amending regulations made in May 2026; the safety-switch part of the regulations now holds one rule, which applies from 1 December 2028.
The work spreads across the City of Darwin, Palmerston and Litchfield. Darwin's suburbs reach Lee Point in the north and Berrimah in the east, with the airport and RAAF Base Darwin between the older suburbs and the northern ones. Palmerston sits to the south-east, and Litchfield's rural localities, from Howard Springs and Coolalinga to Humpty Doo and Berry Springs, run out beyond it. The main industrial areas line the Stuart Highway towards Palmerston, centred on Winnellie, and Middle Arm has an industrial precinct of its own, so commercial and maintenance work deserves its own page rather than a line at the bottom of a domestic one. The Act requires every owner or occupier of land to do what is reasonably practicable to keep vegetation clear of powerlines, which matters most on acreage, and the regulations make the person in control of a private overhead line keep trees around it trimmed. Where an owner doesn't, or the vegetation creates a risk, Power and Water can enter, clear it and recover the cost. If you replace private poles or put consumer mains underground, rural owners need to read that you do.
The weather sets the calendar. The wet season usually arrives in late November or early December with monsoon rain, lightning and a higher chance of cyclones, and on 31 January 2002 a single squall line produced more than 5,000 cloud-to-ground strikes within 60 km of the city. We're an Adelaide team at Hutt St, and none of our current clients is in the Territory. Everything runs by phone and email, and because the NT has no daylight saving, Adelaide runs an hour ahead of Darwin from early October to early April, so we set call times in Darwin time. The rules above come from the Act and regulations as published by the Territory; check anything about your own licence with NT WorkSafe before it goes on your site.
