Plumber lacks a reliable method to verify that other tradespeople are properly qualified and registered for unvented hot water installations, leading to dangerous installations.

There is no easy way to check unvented qualifications and Competent Persons Scheme membership of other tradespeople; the current check is manual, unreliable, and often skipped, resulting in illegal and dangerous installations.
