In Victoria, any plumbing work that alters or repairs a fixed water supply, or involves gas fitting, legally requires a licensed plumber. This ensures work meets the Plumbing Regulations 2018 and the National Construction Code, safeguarding health and property.
As of December 2025, when preparing a property for sale in Melbourne’s Eastern Suburbs, sellers frequently encounter plumbing considerations. A pre-sale building and pest inspection will highlight any non-compliant work. Common issues requiring a licensed plumber include replacing tapware, fixing leaking toilets, unblocking drains, and installing or modifying hot water systems. Even seemingly minor repairs, like a dripping showerhead, can become a point of negotiation if not completed by a licensed professional. Currently in Melbourne, buyers – and their building inspectors – are particularly attentive to plumbing, as rectification costs can be significant. We often see properties in areas like Balwyn and Doncaster benefit from proactive plumbing checks before campaign launch. In 2026, expect continued scrutiny of plumbing compliance during the due diligence period, potentially impacting sale price or settlement conditions. Typical plumbing repair costs range from $150 for a minor leak to $1,000+ for hot water system repairs.
Ensuring plumbing work is completed by a licensed plumber protects both sellers and buyers, and contributes to a smoother property transaction.
