5.1 Certificate of Compliance (Regulation 65)

5.1 Certificate of Compliance (Regulation 65)

On the EWRB electrician registration regulations exam, certification is not “paperwork after the real job.” The Certificate of Compliance (CoC) is the primary legal instrument that says prescribed electrical work (PEW) was carried out lawfully, safely, and in accordance with the Electricity (Safety) Regulations 2010 (ESR) and the applicable standards. Regulation 65 is the usual open-book anchor for when a CoC is required and what it is meant to certify. Candidates who mix CoC, Electrical Safety Certificate (ESC), and Record of Inspection (RoI) roles lose easy marks—so learn each document’s purpose before memorising form layouts.

What a CoC certifies

A CoC certifies that the PEW:

• was carried out in accordance with the ESR 2010 and any other applicable requirements under the Electricity Act framework
• complies with the applicable standards cited for that work (commonly AS/NZS 3000 and related Schedule 2 instruments where they apply)
• is electrically safe as that concept is used in the Regulations—not merely “the customer is happy” or “it powered up once”

In plain exam language: the CoC is the worker’s formal statement that the work itself is compliant and safe. It is not a network company connection application, not a building consent, and not the independent inspector’s record used for high-risk PEW.

When a CoC is required (reg 65 pathway)

Under the ESR risk-category model taught for this exam:

The hard rule for exam stems: a CoC is required for all general-risk and high-risk PEW. If a stem describes everyday installation work such as adding circuits, altering wiring, or other general-risk PEW, “no certificate needed” is almost always wrong. If the stem is high-risk (for example new mains, certain submain or main-switchboard work on a new installation—confirm exact high-risk definitions in ESR), a CoC is still required in addition to the inspector pathway.

Who issues the CoC

The CoC is issued by the authorised electrical worker who carried out or supervised the PEW and who is entitled to certify that work under their EWRB registration class and current practising licence. Key implications:

• You certify work you did or supervised and verified—not work you never saw, never tested, or only “helped on for an hour.”
• A trainee does not complete certification alone; supervisory arrangements matter for who can lawfully sign.
• Issuing a CoC for work you did not do or cannot verify is false certification—a regulatory breach that can attract EWRB discipline, not a “admin shortcut.”

Open-book exam technique: if the stem asks who may issue, open ESR wording on certification responsibility and match it to registration class (electrician for typical installation PEW; Electrical Inspector for RoI, not as a substitute CoC issuer for someone else’s un-supervised work).

Content themes: what the CoC must cover

Exact field lists live in the current ESR / approved forms, but exam and industry teaching consistently expect CoC content themes around:

1. What work — identify the PEW performed (scope: new circuit, alteration, switchboard work, etc.).
2. Where — identify the installation/location so the record can be audited later.
3. Who — identify the certifier (registration/licence details of the authorised worker).
4. Standards applied — confirm compliance with the Regulations and applicable standards used for the work.
5. Evidence of safety/compliance — relevant test and verification results that support the certification (verification detail is expanded in the testing chapters; here, know that results support the CoC).

A CoC that only names a price and a date is not a valid compliance record. Treat “minimum information” stems as: work + place + person + standards/compliance + supporting verification, not commercial invoice fields.

Relationship to “safe to connect” before energising

Do not confuse compliance of the work with safe to connect / use after connection:

• CoC → the PEW complies with ESR and applicable standards (reg 65 pathway).
• ESC → after connection (where required), the work is safe to use and does not leave other parts unsafe (regs 74A / 74C pathway—detailed in section 5.2).
• Verification tests (AS/NZS 3000 section 8 sequence) → technical evidence that underpins both instruments before you energise or certify.

Practically, authorised workers verify before connection, issue the CoC for general/high-risk PEW, and only treat connection/energisation as complete when the full chain for that risk category is satisfied. For high-risk PEW, independent inspection/RoI sits in that chain before connection as applicable—CoC alone does not “clear” high-risk work.

What a CoC is not

Exam traps often rephrase the same mistakes:

Timeframes and supply to the client (preview)

Section 3.4 covered ESR time limits after completion. For exam flow with CoC content:

• Issue the CoC promptly after the PEW is completed, and give the client a copy within 20 days after completing the work (reg 74E(2) — calendar days, not working days).
• Provide the certificate to the person who contracted for the work (client/person entitled to receive it).
• Retain a copy for at least 7 years (reg 74E(3)), and produce it within 10 working days of an authorised request (reg 74E(4)); full chain in section 5.4 and every clock in section 5.5.

Exam scenario patterns for reg 65

Pattern A — General-risk PEW finished. Expect CoC (and ESC when connected). “ESC only” is incomplete if the stem is general-risk PEW requiring compliance certification.

Pattern B — High-risk PEW finished. Expect CoC plus inspector RoI before the high-risk chain is complete; ESC when energised/connected. “CoC alone finishes high-risk” is a classic wrong answer.

Pattern C — Low-risk PEW. Do not invent a CoC if ESR does not require one for that category—but do not assume “no documents at all”; ESC may still apply.

Pattern D — False certification. Options that allow certifying untested work, someone else’s unsupervised PEW, or unsafe work as compliant are always wrong.

Open-book checklist for CoC items

1. Is the activity PEW?
2. What risk category (low / general / high)?
3. If general or high → CoC required (reg 65).
4. Who is the authorised certifier for that work?
5. Does the stem also need ESC (connection/use) or RoI (high-risk inspection)?
6. Confirm issue timing and client copy duties in ESR under time pressure.

Master the CoC as compliance of PEW by the authorised worker for general- and high-risk work, and the rest of the certification suite becomes much easier to place.
