Building and Construction Sector (Self-certification by Plumbers and Drainlayers) Amendment Bill
This bill changes the Building Act 2004 and the Plumbers, Gasfitters, and Drainlayers Act 2006. It creates a new system where certain qualified plumbers and drainlayers can 'self-certify' their own work, meaning they can confirm it meets building standards without needing a separate check from a council. This applies only to specific types of plumbing and drainlaying work that are considered routine and low-risk. These plumbers and drainlayers will need a special endorsement on their licence and will be subject to audits.
