What documentation is typically required before beginning a major electrical installation?

Before beginning a major electrical installation, obtaining a Certificate of Compliance (CoC) is a critical requirement. The CoC ensures that the electrical installation meets the relevant safety standards and regulations. This document serves as proof that a qualified professional has inspected and verified the work, ensuring it complies with the national electrical code and local regulations. It not only confirms the safety of the installation but also provides accountability in the case of future inspections or electrical issues.

On the other hand, while a project budget proposal might be necessary for planning purposes, it does not directly relate to the safety or compliance of the electrical work itself. Approval from electrical suppliers may be important for ensuring the correct materials and components are sourced, but it is not a formal requirement like the CoC. Similarly, having a list of needed tools and equipment can help in project preparation but does not address the regulatory and safety standards that the CoC confirms before an installation begins.
