Electricians in the Northern TerritoryTwo rule changes this year worth knowing.

In the Northern Territory, anyone doing or supervising electrical work needs an electrical work licence, and the business needs an electrical contractor licence. Since 1 July 2026, a contractor's ads must show their licence number. After the job, you should get a certificate of compliance within 20 business days.

Who's licensed to do electrical work in the NT?

The Electrical Safety Act 2022 sets up three licences: an electrical work licence for individuals, an electrical contractor licence for businesses, and an in-house electrical licence. Work licences are either unrestricted (electrical mechanic, or electrical mechanic and fitter) or restricted to the work listed on them.

Every contractor must use licensed workers and hold at least $5,000,000 of public and products liability insurance. Electrical work without a licence, or contracting without one, carries a maximum of 500 penalty units, and one NT penalty unit has been worth $194 since 1 July 2026.

Checking a licence, and reading an ad

From 1 July 2026, a contractor's ads must state their licensed or registered business name, that they're licensed under the Electrical Safety Act 2022, and their contractor licence number. Names on uniforms, vans and buildings don't count as advertising for this rule.

The Electrical Safety Regulator must keep a register showing each licensee's name, licence number, issue date, renewals and any disciplinary action. We couldn't confirm whether it's searchable online, so if you can't verify a number yourself, ask the Regulator.

Your certificate of compliance

The electrician, or their contractor, completes it to certify the work was tested as safe and meets the law and standards. Within 20 business days of finishing, copies go to the owner and occupier, the person the work was done for, and the Regulator, which keeps it for 30 years.

You won't get one for maintenance, or for swapping a fitting or appliance for a similar one in the same spot that works the same way and draws no more power.

Safety switches: what changed in May

The Territory scrapped its landlord safety switch rules on 28 May 2026. One rule remains: from 1 December 2028, nobody may do electrical work on a home's installation, rentals included, unless an approved safety switch is installed. The only exceptions are connecting the home to power and urgent or emergency work.

An approved safety switch is an RCD (it cuts the power when current leaks to earth) registered in the national Electrical Equipment Safety System.

Smoke alarms in Territory homes

Every home owner must have approved alarms: photoelectric, meeting AS 3786, and either hardwired or a sealed 10-year lithium unit. Older ionisation alarms that complied when the rule began can stay only until one stops working, the home is sold, or a tenancy starts, renews or extends. Owner-occupiers must test and clean each alarm at least every 12 months and replace any that fails straight away.

Landlords test, clean and replace failed alarms within 30 days before a tenancy starts, and give the tenant written instructions. During the tenancy, the tenant tests and cleans them yearly and reports any failure to the owner.

Our take for the Territory

Match the licence number in the ad to the electrician you're actually dealing with, and ask for the certificate of compliance at the end. If your switchboard has no safety switch, we'd have one fitted well before December 2028, so a future repair doesn't stall waiting for it.
