Hiring an Electrical Contractor
See section on selecting a Sub-contractor
Firstly, ensure the contractor has an electrical contracting licence issued by the Office of Fair Trading in NSW - There are similar government departments in other States.
Secondly, for peace of mind, employ a member of the National Electrical Contractors Association (NECA). NECA members abide by a strict Code of Ethics. If there are any major concerns you can call the Association for assistance.
Thirdly, be sure to obtain a minimum of two quotes from electrical contractors. There are NECA recommended charge out rates, but these are not compulsory rates.
Documentation or a written contract is required for all work performed over $200. Ensure that the electrical contractor has such documentation.
Once the work is completed the contractor should give you a copy of a Notification of Electrical Work (NOEW) form. The electrical contractor keeps a copy for their records and a copy is sent to the local Supply Authority.
Electrical Work Householders Can Do
It is illegal for unlicensed persons to perform any type of mains voltage electrical work. This requirement is in place for obvious safety reasons. Changing light bulbs is the extent of 'electrical' work householders can legally perform.
