Certificate of Compliance for Electrical Work in the NT: What to Know
Shock your friends with this post.
Key Takeaways
- Nearly all electrical work in the NT needs a certificate of compliance: this includes installations, alterations, additions and repairs.
- Your electrician completes it, not you: the contractor submits it online and stays responsible for the work.
- You should receive a copy: owners, occupiers and the person who commissioned the work are all entitled to one.
- Timing matters: the certificate is due within 20 business days of finishing the work.
What Is a Certificate of Compliance for Electrical Work in the NT?
A certificate of compliance is the official record that electrical work in the Northern Territory has been completed by a licensed worker. If an electrician has installed, altered or repaired something at your property, a certificate should follow.
The rules sit under the Electrical Safety Act 2022, which commenced on 1 July 2024. NT WorkSafe regulates the process, and many Darwin property owners still think of it as the old certificate of electrical safety.
Which Electrical Work Needs a Certificate?
Almost every job carried out by a licensed electrician needs one. The work that normally requires a certificate includes:
- New electrical installations
- Alterations to existing wiring or circuits
- Additions, such as new power points, lights or circuits
- Repairs to electrical installations or fixed equipment
Some low-risk jobs are exempt from the certificate requirement. The main exemptions are:
- Maintenance that does not involve installation, alteration, addition or repair, such as replacing a light globe
- A temporary builder’s supply
- Specific low-risk work listed by NT WorkSafe under recent reforms
Check the current NT WorkSafe list before you assume a job is exempt, because the rules have been updated recently. If in doubt, ask your electrician before the work begins.
Who Completes and Receives the Certificate?
The electrical contractor completes and submits the certificate. A contractor may authorise a worker to sign it, but the contractor stays liable for the work. Copies go to several people, as the table shows.
| Who | Their role |
|---|---|
| Electrical contractor | Completes and submits the certificate, and remains liable |
| Property owner and occupier | Receive a copy for their records |
| Person who commissioned the work | Receives a copy, which may be a tenant, builder or business owner |
| Network operator | Receives a copy for work that relates to the network |
| NT WorkSafe | Receives the submitted certificate as regulator |
If you are a landlord or manage a property, ask your electrician to confirm who has received the paperwork, so nothing is missed when tenants or managers change.
How Long Does an Electrician Have to Provide It?
The certificate is due within 20 business days of completing the work. Most reputable contractors handle it quickly, and the NT Government says the online process takes about 10 to 15 minutes. That is a short task, so there is rarely a good reason for long delays.
There is no fee to lodge the certificate itself. Any cost you see on a quote relates to the electrical work, not to the government lodgement. If you are waiting longer than 20 business days, contact your electrician first, then NT WorkSafe.
How to Check Your Certificate Is Correct
Keep your copy with your property records. When it arrives, take a few minutes to read it, using this checklist:
- Check the property address matches your site.
- Confirm the description of the work matches what was done.
- Look for the contractor’s details and licence information.
- Check the date the work was completed.
- Ask your electrician to correct anything that looks wrong.
Good records can be useful if you sell, insure or change the property later, or if you need to show what work was done and by whom.
Why the Certificate Matters for Safety
The certificate is more than paperwork. It shows that a licensed worker took responsibility for the work and that it is on the regulator’s record. That matters when something goes wrong years later, or when a new owner wants to know the history of the electrical work.
Unlicensed or unreported electrical work is a risk to your household and the next owner of the property. Missing paperwork can cause problems such as:
- No clear proof that a licensed worker did the job
- Questions from your insurer after a fault or fire
- Delays or awkward conversations when you sell
- Confusion about who is responsible for the work
If you are unsure about work done in the past, an electrical safety inspection can check the condition of your wiring and safety devices.
Certificates for Commercial and Industrial Work
The same expectations apply to shops, offices, warehouses and other workplaces. Business owners often assume the fit-out contractor has taken care of it, but you should ask for your copy. Typical commercial jobs that need a certificate include:
- Wiring for a new fit-out or tenancy
- Extra circuits for kitchen, workshop or refrigeration equipment
- Lighting and power upgrades
- Switchboard changes and repairs

How to Choose an Electrician Who Does the Paperwork Properly
A good electrician explains what they are doing and why. Before you book, ask these questions:
- Are you licensed for the work you are quoting?
- Will you complete and submit the certificate of compliance?
- When can I expect my copy?
- Who is responsible if I have a problem later?
