In NSW, plumbing, draining and gasfitting count as specialist work: you need a licence or certificate whatever the job is worth, and whether it's residential, commercial or industrial. The options are an individual, company or partnership contractor licence, a qualified supervisor certificate and a tradesperson certificate, and only a contractor licence lets you contract for work. Building Commission NSW handles licensing for tradespeople. The Home Building Act 1989 bars advertising specialist work without a current contractor licence, and NSW Fair Trading says ads must show the licensee's name (or a registered business name), the licence number, the category of work and a business phone number. Its guidance covers internet advertising, which takes in your website.
Jobs needing an inspection in Sydney go through Building Commission NSW. The plumber lodges a Notice of Work through the MyInspections Gateway, then a Certificate of Compliance once the work is finished, with a copy for whoever arranged it, whether that's the owner or a builder. Drainage work also needs a Sewer Service Diagram, again with a copy for the person who arranged the job. Emergency work and minor jobs, such as swapping tapware or replacing an existing hot water system, don't need a Notice of Work. For gas, the fitter must give the customer a certificate of compliance for mains (network) gas or a certificate of inspection for bottled gas, showing their name and licence number. Your site doesn't need the detail, but one line saying you handle it reassures people.
Sydney Water supplies Sydney, the Illawarra and the Blue Mountains, and its rules shape plenty of plumbing calls. Owners are responsible for the pipes and fittings on their property up to the point where they connect to Sydney Water's network, so a blockage in a private sewer line is a job for a licensed plumber, while a fault in Sydney Water's own pipes is theirs to fix. Medium and high hazard backflow devices have to be tested at installation and then yearly by a backflow-accredited plumber, who submits the report through Sydney Water's Backflow Prevention system, and Sydney Water publishes a search of backflow plumbers. If you're on it, say so on your site.
Customers don't think in council areas; they think in regions: the Eastern Suburbs, the Inner West, the Lower and Upper North Shore, the Northern Beaches, the Hills District, Greater Western Sydney, Canterbury-Bankstown, Macarthur, St George and the Sutherland Shire. We'd list the regions you work in, name the main suburbs under each, and leave out the ones you won't drive to. If you'd rather not cross the harbour for small jobs, the site can say so, and the list can change whenever you like after launch.
We're an Adelaide team based on Hutt St, and we build sites for NSW businesses by phone and email; Western Sydney Stump Grinding is one of them. You send your services, licence details, regions and a few job photos. We send a draft link you can open on your phone between jobs, and you pay once you're happy with it.
