Is your website missing the licence number WA law says it must show?
Your website is an advertisement, and WA law requires your registration or licence number to appear in it: up to a $5,000 fine for builders and painters who leave it off, $2,000 for plumbers, and electricians must show their EC number in all advertising. Submit your site and find out in two minutes, along with anything else worth fixing: misleading claims, out-of-licence services, bait pricing.

Example finding
This automated review is general information only, not legal advice or a regulator's determination. Findings are potential issues for your review.
What the check looks for
Building and Energy (DEMIRS) administers the licence and registration rules for WA builders, painters, electricians, plumbers and gas fitters, and it prosecutes advertising breaches. The checker reads up to five pages of your site and flags content against each rule, starting with the simplest one to get wrong.
Licence number not shown
WA law says your registration or licence number must appear in your advertising, and your website counts. Builders and painters risk a $5,000 fine, plumbers $2,000, and electricians must show their EC number in all advertising.
False or misleading claims
"Perth's best", award and membership claims with nothing behind them, and "lifetime guarantee" promises with no terms are Australian Consumer Law problems.
Work advertised outside your licence
An electrician advertising gasfitting, or a painter advertising structural work, is advertising services it is not authorised to provide. Builders using licensed subcontractors are fine.
Bait pricing and offers without terms
"From $99" specials that few customers actually get, and discounts with no conditions or expiry. Genuinely free quotes are fine, and never flagged.
Qualification inflation
"Master builder" without the membership, or vague "certified" and "accredited" claims with no certifier named.
It does not see Facebook or Instagram pages, Google Business Profiles, paid ads, vehicle or site signage, or licence numbers shown only inside images; the same rules apply to all of these.
Questions tradies ask
Does my website really count as an advertisement?
Yes. Building and Energy (DEMIRS) treats websites the same as newspaper ads, flyers, and vehicle signage: if it promotes your availability to do the work, it is an advertisement and the licence number rules apply to it. Facebook pages and Google Business Profiles count too, though this tool cannot scan those.
What number do I need to show?
Builders and painters: your Building Services Board registration number, under section 8 of the Building Services (Registration) Act 2011, penalty up to $5,000. Electrical contractors: your EC licence number, in all advertising, with guidance that it be at least half the size of your largest lettering. Plumbers: your PL licence number, penalty $2,000. Gas fitters: your permit details.
Are testimonials and free quotes allowed?
Yes to both. Customer reviews are fine unless the content itself is misleading, and a genuinely free quote is standard practice. What gets flagged is a "free" or discounted offer that turns out to have hidden conditions.
Does the regulator actually enforce this?
Yes. Building and Energy publishes disciplinary and prosecution outcomes for builders, painters, electricians and plumbers, and advertising breaches, including missing licence numbers, appear in them regularly. It is one of the easiest things for a regulator, or a competitor, to spot.
Is this check legal advice?
No. It is an automated review that flags potential issues for you to look at. It is general information only, not legal advice or a determination by any regulator, and a clean result is not a compliance guarantee.
Why do you need my work email?
The full report is delivered by email, and the tool costs us real money to run per scan, so we limit it to business owners with a work email address. We email your report and may follow up once about it. No list, no spam.
