3.4 Certification Timeframes & Notification Duties under ESR
Key Takeaways
- ESR triggers CoC, ESC, and RoI obligations based on PEW risk category and completion/connection context—document content is a later chapter; timeframes and duties start here
- Regulation 74E(2) allows 20 days—calendar days, not working days—after completing the work to give the client a copy of the certificate of compliance, while regulation 74C requires the electrical safety certificate to be issued no later than 20 working days after connection
- Certification records must be retained for at least 7 years (regs 72A(1)(b), 74E(3) and 74G(1)(b)) and produced within 10 working days of a request from WorkSafe, the Board, the Registrar, the territorial authority, the person who contracted for the work, or the owner or occupier
- Higher-risk PEW brings tighter inspection/certification chains (including RoI by an Electrical Inspector for high-risk work under the reg 72 pathway)
- Exam scenarios after a finished job ask: which document(s), who issues them, and by when—answer from ESR timeframes and risk category, not from memory of a single employer’s form
Certification Duties at Regulatory Level
Later chapters unpack the full content of a Certificate of Compliance (CoC), an Electrical Safety Certificate (ESC), and a Record of Inspection (RoI). This section stays at the ESR duty and timeframe layer: when obligations are triggered, how risk category changes the chain, how soon documents must be issued, and what record-keeping expectations look like for exam purposes.
What each document is for (duty-level only)
| Document | Regulatory role (high level) | Typical trigger framing |
|---|---|---|
| CoC (often taught against reg 65) | Certifies that PEW complies with the Regulations and applicable standards | General- and high-risk PEW on completion |
| ESC | Confirms the installation (or work) is safe to connect/energise as framed by ESR | Connection/energisation safety after work |
| RoI (often taught against reg 72) | Record issued by an Electrical Inspector after inspecting high-risk PEW | High-risk PEW inspection pathway |
Do not treat these as interchangeable employer forms. The exam tests which instrument the regulations require for the risk category and stage of work.
When obligations are triggered
Think in three steps:
- Was PEW done? If not PEW, the full certification suite may not apply (though other safety duties can).
- What risk category? Low-, general-, and high-risk PEW (detailed in the PEW chapter) change whether a CoC is required, whether an ESC is needed for connection, and whether an inspector’s RoI path applies.
- What is happening to the installation? Completion, connection, and high-risk inspection each pull different documents.
A finished job on general-risk PEW without any certificate is a classic fail path. High-risk PEW completed without the inspector/RoI chain is another.
Time Limits for Issuing Certificates
The ESR publish exact deadlines, so there is nothing to guess here. What separates a confident candidate from a hesitant one is knowing that the Regulations use two different clocks and knowing which regulation carries which.
The days versus working days distinction
| Duty | Regulation | Deadline | Clock starts |
|---|---|---|---|
| Provide the CoC copy to the client | 74E(2) | 20 days — calendar days | Completing the work |
| Provide the RoI copy to the client | 72A(1)(a) | 20 working days | The RoI being issued |
| Issue the ESC | 74C | As soon as practicable, and no later than 20 working days | Connection to a power supply |
| Provide the ESC copy to the client | 74G(1)(a) | 20 working days | The ESC being issued |
| Produce any of them on request | 72A(2), 74E(4), 74G(2) | 10 working days | The request |
Regulation 74E(2) is the odd one out: it says “within 20 days after completing the work”, not working days, and it runs from completion of the work rather than from issue of the certificate. Every other 20-unit deadline in this part of the Regulations is expressed in working days. Across a period containing public holidays the two clocks can differ by more than a fortnight, so when a stem offers both, that difference is the whole question.
- Learn the concept: certification is time-bound, and late issue is itself a breach even if the wiring was faultless.
- Learn the regulation numbers so you can confirm the figure in seconds with the ESR open.
- Do not substitute a period from another jurisdiction (Australian schemes use different windows).
Section 5.5 sets out every clock in this family, including retention and the high-risk database lodgement.
Completion clocks and partial jobs
Stems may describe staged work. Regulatory thinking asks when the PEW (or a certifiable portion) was completed for the purpose of the certificate duty. “I’ll certify next month when I am less busy” is not a defence if the ESR period has run. If multiple workers touch the job, responsibility still has to land on the person required to certify that PEW—another reason supervision and clear responsibility matter.
Record Retention Expectations
Issuing a certificate is only half the duty. ESR expects retention of records for a defined period so the work can be audited, investigated after an incident, or reviewed by the Board or other authorities. For exam prep:
- Know that retention is mandatory, not optional filing.
- Locate the current retention period in ESR rather than relying on a single employer’s archive policy.
- Retention applies to the certification documents and associated records the regulations require you to keep (what exactly must be kept is expanded in the certification chapter).
A worker who issues a CoC but cannot produce records when asked has not fully discharged the regulatory duty set.
Connection to PEW Risk Category
Risk category is the switchboard of certification duties:
| Risk category (overview) | Certification chain emphasis |
|---|---|
| Low-risk PEW | Reduced certification burden relative to general/high—confirm exact ESR treatment; do not assume “no rules” |
| General-risk PEW | CoC pathway (reg 65 framing) and ESC where connection safety must be certified |
| High-risk PEW | CoC plus inspection / RoI (reg 72) by an Electrical Inspector before the high-risk chain is complete |
Exam traps:
- Treating high-risk work as if a CoC alone always finishes the legal chain.
- Treating all PEW as high-risk requiring an RoI.
- Forgetting that ESC addresses safe to connect, which is related to but not identical to CoC compliance wording.
Use risk category first, then pick documents, then apply timeframe and retention duties.
Practical Exam Scenarios: Finished Job—What and By When?
Scenario pattern A — General-risk PEW completed
Work on a domestic installation finishes; risk category is general. Expected regulatory thinking:
- Issue the CoC (reg 65 pathway) for the PEW.
- Issue an ESC if the situation requires certification that the work/installation is safe to connect.
- Supply the CoC copy within 20 days after completing the work (reg 74E(2)) and issue the ESC within 20 working days after connection (reg 74C).
- Keep records for the ESR retention period.
Scenario pattern B — High-risk PEW completed
High-risk PEW finishes. Expected thinking:
- Compliance certification still matters (CoC pathway).
- An Electrical Inspector must complete the inspection / RoI (reg 72) duties that high-risk work attracts.
- Connection/energisation should not be treated as freely available until the high-risk inspection/certification chain the regulations require is satisfied.
- Timeframes for issuing records still run from completion—locate exact ESR wording under pressure.
Scenario pattern C — Work finished, certificates “later sometime”
If options include waiting indefinitely, only certifying if the customer asks, or backdating without having tested, reject them. ESR attaches positive duties to issue on time and to retain records—not merely reactive paperwork when a dispute starts.
Scenario pattern D — Notification-style duties
Depending on the work and regulation path, ESR also frames provision of certificates to the person who contracted for the work and related information duties. Exam answers should reflect giving the required documents to the right person within the required time, not filing them only in a private drawer. Confirm any specific notification or lodgement requirements in the current ESR text for your sitting.
Open-book checklist for certification timeframe items
- Identify PEW and risk category.
- List documents: CoC / ESC / RoI as applicable.
- Open ESR for issue-by period after completion.
- Open ESR for retention period.
- Match who may issue (electrician vs inspector) to the document.
- Choose the option that satisfies category + document + time + person.
Master this checklist and section 3.4 becomes a reliable points bank: most mistakes are category mix-ups or invented day-counts, not obscure theory.
