To make an informed decision about the providers or workers you employ or work with, you can search their compliance record to see if they have received any current or past compliance or enforcement actions. More information about the actions included in the search.
- The search looks for individual, sole trader, trading names or company names.
- Search for a business using a single word or partial word, as this may find spelling or name variations.
- Search for a worker using first name or last name, not both.
- If you've searched different possible spellings, action types or years and don't find any results, it's likely the provider or worker hasn't received any enforcement actions.
