Certification There are 3 types of certifications required and used in plumbing and gas works in WA.
Major Works Certification – this is a single per job certificate required for all hot water system installations, below ground drainage works and fixture re-locations during a renovation.
Minor Works Certification – this is a single page certificate that contains 25-line items for 25 separate jobs. All licensed plumbing works undertaken are required to add a line item to their minor works certificate page. This includes anything from toilet and tap servicing through to full kitchen renovations where no fixture has moved.
Gas Compliance Certification – Any gas works undertaken requires a single page certificate. One copy is given to the client and the other copy is submitted to ATCO. The licensed plumber must also install a completion badge in the properties gas meter box. This is to communicate to all future plumbers what kind of gas works took place and when.

Leak Allowance Form
A leak allowance form is a form that licensed plumbers can submit to the Water Corporation to receive a rebate on a consumer water bill. This can only be submitted when a non-visible leak/burst-pipe has occurred. Plumbing Bros. charge a $20 administration fee to complete and submit leak allowance forms.
