A Brisbane business owner who is owed $1 million is furious at the Queensland Building and Construction Commission (QBCC) for what he labels a lack of action and regulation.

Stefan Styles operates one of Queensland's largest shower screen and wardrobe companies, employing about 120 people. Mr Styles said the industry is still recovering from a difficult year, and says the QBCC is to blame.

A QBCC spokesperson said that over 300 licensees were suspended or cancelled in the last year for not meeting Minimum Financial Requirements (MFR).
