On the NSW side, the state rules are the ones our Sydney plumbers page explains: a licence for plumbing, draining or gasfitting work of any size, a contractor licence to contract for it, and NSW Fair Trading's advertising guidance asking for the licensee's name, licence number, category and a business phone in ads, websites included. The local difference is that AlburyCity is both the water and sewer authority and the plumbing regulator. A plumbing approval is lodged through the NSW Planning Portal or on council's form before work starts, a Notice of Work goes in at least 2 working days beforehand, and the Sewer Service Diagram and Certificate of Compliance reach council before the final inspection is booked, each quoting the approval number.
Across the river, plumbing is regulated by Victoria's Building and Plumbing Commission, and our Melbourne plumbers page goes through its registration, licensing and compliance certificate rules. Water and sewer in Wodonga come from North East Water, which serves around 120,000 people in 39 towns across north-east Victoria. Its backflow rules put the testing on the owner: a containment device at every meter on medium and high hazard sites, tested every 12 months, with the report sent to North East Water within 20 days. Its examples of where those devices are needed include toilet douche sprays or flexible hoses, below-ground rainwater tanks connected to toilet cisterns, grease interceptors at non-residential sites, and caravan parks.
Working both sides takes a licence or registration in each state, or automatic mutual recognition, which means notifying the other state's regulator before you start. Interstate plumbing, draining and gasfitting licensees must notify Building Commission NSW, through Service NSW, before working in NSW under the scheme, and building and plumbing practitioners must notify the Building and Plumbing Commission before working in Victoria. Both states set conditions on the scheme, so check with each regulator before relying on it. Your website should only list the side, and the work, you're authorised for.
Gas is where the two cities are drifting apart. Victoria's Building Electrification Regulations require new homes to be all-electric from 1 January 2027, although a home whose building permit is approved before 31 December 2026 may still be able to connect. From 1 March 2027, a gas hot water system in an existing Victorian home that can't be repaired must be replaced with an electric one such as a heat pump; repairs are still allowed, apartment buildings with central hot water are excluded, and AusNet notes that bottled LPG can still be used for hot water and cooking in regional homes. None of that changes anything in Albury. A plumber's hot water page that explains the split, side by side, is more useful to a Wodonga homeowner than a generic list of brands.
Some smaller local details are worth a line too. AlburyCity runs a "No wipes for Albury's pipes" campaign and points out that wipes can block a householder's own drains as well as its sewers, which suits a blocked-drains section. Its sewer serves urban Albury, Hume Weir Village and Lara Lakes at Table Top, and owners outside that network need council's approvals for their on-site systems, including a new owner, who has to apply within two months of the sale. We're an Adelaide team on Hutt St, and we work with border businesses by phone and email; you send your licence details, suburbs and photos, and we send back a draft link you can check from the ute.
