Before you sell or lease a home in Western Australia, there are a few electrical requirements the law says must be met — and they catch a lot of owners out at the worst possible time, right before settlement or a new tenancy. Here’s a plain-English rundown from a licensed Perth electrician of what you actually need, so there are no surprises.
1. Safety switches (RCDs) — at least two
WA law requires a minimum of two RCDs (residual current devices, or “safety switches”) protecting all the power and lighting circuits in a home before it can be sold (the land title can’t transfer without them) or rented out. The same applies to short-stay accommodation.
Bigger homes often need more than two, because each RCD can protect no more than three final sub-circuits — so the exact number depends on how many circuits your switchboard has. A quick check: press the “T” (test) button on each safety switch; if the power doesn’t cut out, it needs looking at by a licensed electrician.
2. Smoke alarms — mains-powered
For a home being sold or rented in WA, smoke alarms must be mains-powered (hard-wired) — battery-only units don’t meet the requirement. They also need replacing every 10 years, so check the date stamped on each alarm. If yours are battery units or past their date, they’ll need replacing before the sale or new lease.
3. Electrical safety certificate
Whenever electrical work is carried out, a licensed electrical contractor must provide you with an electrical safety certificate within 28 days. It certifies the work was completed, tested and complies with the regulations — your proof the wiring is safe, and an important document to keep for the sale.
What it means for you
If you’re selling or leasing and you’re not sure whether your safety switches and smoke alarms are up to standard, it’s worth getting them checked early rather than scrambling before settlement. Most of this work — fitting RCDs, hard-wiring smoke alarms and issuing the certificate — can often be done same-day.
