When locals say Newcastle they often mean more than the City of Newcastle council area. The NSW Government's Greater Newcastle Metropolitan Plan covers five councils: Newcastle, Lake Macquarie, Maitland, Port Stephens and Cessnock. Those five names make a sensible frame for your service area, with the suburbs you work in most listed under each one.
Licensing is the same as anywhere in NSW. Building Commission NSW handles building and trade licences, and electrical wiring, plumbing, drainage, gasfitting, and air conditioning and refrigeration work need a contractor licence whatever the job is worth. Government guidance says your licence name and number must appear in your advertising; the Housing Industry Association lists the internet, social media and vehicles among the places that applies. Customers can confirm your licence, its categories and its expiry date on the Verify licence site.
Past underground mining means parts of the Hunter sit inside declared Mine Subsidence Districts, among them Newcastle, Lake Macquarie, Killingworth-Wallsend and East Maitland. Anyone planning to build or subdivide in a district needs approval from Subsidence Advisory NSW before work starts, although some minor works, such as small carports, decks and fences, don't need it. City of Newcastle's development control plan also says mine subsidence must be considered in the preliminary design of all development. If your work involves those approvals, saying so on your site is worth a sentence.
The region is growing. The NSW Government's Hunter Regional Plan 2041 expects the Hunter's population of about 860,000 to reach nearly 950,000 by 2041 and plans for an extra 101,800 dwellings. More homes means more households looking for a local electrician, plumber or fencer for the first time.
We're an Adelaide team, so we work with Hunter tradies by phone and email. One of our clients is Phoenix Housekeeping, a cleaning business working across Lake Macquarie, Cessnock and the Central Coast, whose site has suburb pages across its whole service area. That's the same approach we'd suggest for a trade covering several councils: one page or one clear list per area, so each part of the Hunter you serve is named rather than implied.
