In April, former building and construction minister Chris Penk announced a scheme to allow trusted plumbers and drainlayers to self-certify.

The new plumbing and drainlaying self-certification scheme officially starts tomorrow, 7 September 2026.

Master Plumbers CEO Greg Wallace joined Pete Wolfkamp to discuss the changes.
