- A Commercial Electrical COC is the electrical certificate of compliance for business premises: offices, shops, restaurants, warehouses and factories.
- The user or lessor of the installation must have a valid one, with a test report.
- It is needed after shopfits, alterations, on sale of the building, and when landlords, insurers or inspectors ask for it.
- Compare quotes from registered electricians for your premises.
Include the floor area, number of DB boards and whether the supply is three phase.

Factories and industrial sites often have heavy machinery, several sub-boards and sometimes hazardous areas. Specialised installations can only be certified by a master installation electrician. Industrial areas such as Epping, Montague Gardens and Parow Industria are usually quoted after a site visit.
What Happens If the Premises Fails?
The electrician lists the defects and quotes to correct them. Remedial work can often be scheduled after hours to avoid downtime. The COC is issued once everything passes.
