Home building licensing

You must have a contractor licence or employ the holder of a qualified supervisor certificate to contract, subcontract or advertise to do:

• residential building work where the total cost of labour and materials is more than $1,000
• electrical wiring work
• plumbing, draining and gas fitting work
• air conditioning and refrigeration work (except plug-in appliances).

Caution. By law, your licence number must be shown on all advertising, stationery and signage.

If you work without the proper licence, you are breaking the law and can be fined. Also, you will be unable to enforce a contract for the work against the other party.
