For workers not in formal training, limited certificates are replaced with a new exemption type called ‘exemption for plumbing under supervision’.

For the first two years, exempt workers must work:

Following this the certifying plumber must continue to supervise people working under this exemption type, and must test and verify their work.

Time served under a ‘limited certificate’ prior to the introduction of the new ‘exemption under supervision’ counts towards the two year requirement.

The certifying plumber is responsible for notifying the Board and paying the required fee (which is the same as the previous limited certificate) for all exempt workers they supervise.
