Before appointing a registered certifier:

  • check the certifier has the right class of registration for the work (more information below), and read the conditions, if any, on their registration
  • check that the certifier’s registration and insurance are current
  • look up their name on the disciplinary register. This is separate to the certifier register. Check both to get a complete picture.
  • read the contract for certification work carefully.

What type of certifier do you need?

If you need a principal certifier, this will be a registered building surveyor, local council or a registered body corporate. Your principal certifier can advise if you’ll also need to appoint another type of certifier such as an engineer.
