In England, a reasonably handy homeowner can swap a socket faceplate or replace a light fitting without breaking any law. In Australia, the same job done by anyone other than a licensed electrician is illegal in every state and territory. This piece explains why the rules are so much stricter, what you can still do yourself, and what the paperwork looks like when a professional does the work.
A different starting point
British rules on domestic electrics, set out in Part P of the Building Regulations in England and Wales, distinguish between notifiable work, such as a new circuit or work in a bathroom, and minor jobs that an owner may do provided they comply with the wiring regulations. Many people move here assuming something similar applies.
It does not. Australian states treat almost all fixed electrical work as licensed work. That includes installing or replacing power points (the Australian term for sockets), light switches, light fittings, ceiling fans, hard-wired smoke alarms and anything connected to the switchboard. Even running a new cable through a wall to a spot where you plan to have an electrician connect it later is generally off limits. The rules are written by each state, so the detail varies, but the principle is the same everywhere.
Penalties for unlicensed work can be substantial, and responsibility does not end when the job is finished. If faulty DIY wiring later causes a fire or injures someone, the person who did it, and potentially the owner who allowed it, may face serious consequences.
Why the rules are so tight
Several factors are usually cited. Australian homes run on 230 volts like British ones, but the wiring practices, cable types and protective devices differ in ways a UK-trained eye may not expect. Older Australian houses can contain ageing rubber-insulated cable, ceramic fuses and switchboards with no safety switches. Roof spaces get extremely hot in summer, which degrades poor connections faster.
The licensing model also gives regulators a paper trail. Each completed job is documented and can be audited, and safety regulators publish guidance on how to check that a job was done properly. In Victoria, for instance, Energy Safe Victoria regulates electricians and explains the certificates householders should receive. Other states have their own regulators or fair trading bodies doing a similar job.
What you can do yourself
The list is short. Generally you may:
- plug in, use and replace portable appliances and their plugs where those come pre-fitted;
- change light globes (bulbs) and plug-in lamps;
- reset a tripped safety switch or circuit breaker;
- test your safety switches using the test button, which is recommended periodically;
- replace batteries in battery-powered smoke alarms.
Some states allow limited extra tasks, such as certain extra-low-voltage garden lighting systems that plug into a transformer, but check the rules in your state before assuming anything beyond the list above is permitted. When in doubt, it is licensed work.
Hiring an electrician and the paperwork
When a licensed electrician finishes a job, they are normally required to issue a certificate confirming the work complies with the wiring rules and has been tested. The name varies: Victoria uses a Certificate of Electrical Safety, New South Wales a Certificate of Compliance for Electrical Work, and other states have their own equivalents. Keep these with your property records, because a future buyer, insurer or building inspector may ask for them.
Before engaging anyone, check their licence number on the relevant state register; our guide to checking a builder’s or tradie’s licence covers how to do that in each state. Ask for a written quote that describes the work and confirms a compliance certificate will be issued. Consumer organisations such as CHOICE’s home improvement section publish general advice on finding and dealing with tradespeople, which is useful if you are new to the system.
Prices vary by city and by job, and call-out fees are common, so it often makes sense to group several small tasks into one visit.
When you buy an older house
Many British buyers find themselves with a list of small electrical changes after settlement: extra power points, outdoor lighting, an upgrade from old fuses. Asking an electrician to inspect the switchboard and wiring early is sensible, particularly in houses built before the 1990s. Safety switches, known in the UK as RCDs, are now required on new circuits, and some states require them in rental properties or on sale, so an older board may need upgrading. Previous unlicensed work also turns up from time to time, and is best found before it causes a problem.
Questions readers ask
Can I install a ceiling fan if I am qualified in the UK?
Not without an Australian licence. UK electricians can apply to have their qualifications assessed for an Australian licence, but until it is granted the work is unlicensed.
Does my home insurance care about DIY electrics?
It can. If a claim arises from unlicensed electrical work, an insurer may dispute or reduce the payout, depending on the policy terms.
Can I do the trenching for an outdoor power supply?
Some electricians are happy for owners to dig a trench to their specification, but laying and connecting cable is licensed work. Agree the arrangement with the electrician before you dig.
