A Certificate of Currency (produced by an independent party e.g. insurance broker) provides clear evidence that Powerlink (the insured) has a current insurance policy in place. If Powerlink is providing goods or services to a third party, insurance is generally a contractual term and condition that Powerlink needs to provide evidence of via a Certificate of Currency. A Certificate of Currency is generally valid for a 12 month period.

Certificate of Currency – WorkCover Queensland

Certificate of Currency – Motor vehicle

Produced by Powerlink’s insurance broker, Marsh, the Certificate of Currency provides evidence of cover for loss or damage to Powerlink vehicles and also Legal Liability arising out of any accidents.

Certificate of Currency – Combined general liability

Produced by Powerlink’s insurance broker, Marsh, provides evidence of cover for a General Liability and/or Professional Indemnity claim or series of claims.
