Can I replace the plug on an extension lead or appliance myself?
Short answer
In Queensland, no: the Electrical Safety Office lists replacing the plug on the end of an extension lead, and making up an extension lead, as licensed electrical work. We couldn't confirm that any other state allows it either, so don't assume it's fine. The safe options are to replace the whole lead or appliance, or have an electrician or appliance repairer fix it.
Rewiring a plug used to be something every household did. In Australia, it’s now treated as electrical work in at least one state, and it isn’t clearly allowed anywhere else.
The rules by state
| State | Replace a plug on a lead or appliance |
|---|---|
| Queensland | Licensed electrician |
| Other states and territories | Check with the regulator first |
- Queensland: the Electrical Safety Office lists replacing a plug on the end of an extension lead, and constructing an extension lead, as licensed electrical work.
- Everywhere else: we couldn’t confirm the position from the regulators. Don’t assume it’s allowed; ask your state’s electrical safety regulator, or have an electrician do it.
Why it matters
A plug that’s wired wrongly can make the appliance’s metal case live, or leave the earth disconnected so a fault can’t trip the safety switch. Cords with a loose or cracked plug are one of the most common causes of electrical shocks and fires at home.
What to do with a damaged plug or cord
- Stop using it straight away if the plug is cracked, scorched, loose in its casing, or the cord is cut or crushed.
- Replace cheap leads outright. A new extension lead usually costs less than a repair.
- For appliances worth fixing, take them to an appliance repairer or electrician.
- Never tape up a damaged cord as a fix.
What you can do yourself
- Plug appliances into existing power points
- Use powerboards and extension leads that are in good condition, without piggybacking them
- Check leads and plugs for damage before using them outdoors or with power tools
