What an electrical permit to work is
An electrical permit to work is a controlled authorisation used when electrical equipment or conductors have been isolated, locked off and proved dead, so that defined work can be done safely on what would otherwise be a live system. It identifies exactly what is safe to work on and the limits of the work.
This page is an educational overview with a simplified example. It is not an official template, not jurisdiction-specific and not legal advice — the employer decides who is competent and which work needs an electrical permit.
Purpose
- Confirm the equipment is isolated, locked off and proved dead before work.
- Define precisely the point of work and the safe limits around it.
- Coordinate the isolating authority with the people doing the work.
- Record that the system was made safe and later returned to service.
Who completes it
- An authorised person competent in electrical isolation, who issues it.
- The competent person doing the work, who accepts the conditions.
- An isolating authority may be named separately by the employer.
- The employer decides who is competent to isolate, issue and work.
When it is used
- Before work on or near electrical equipment that has been made dead.
- When the work would be unsafe on a live or un-proved system.
- For a stated period, until work is complete and the permit is cancelled.
- Whenever the employer’s system designates the task as permit-controlled.
Typical fields
- Permit number, equipment, point of isolation and the point of work.
- Isolation, locking and proving-dead details and test instrument used.
- Safe limits of the work and any earthing applied.
- Issuer (authorised person) and acceptor signatures.
- Cancellation and return-to-service sign-off before re-energising.
- Example fields only — adapt to the system and the applicable law.
Common mistakes
- Working before the equipment is proved dead at the point of work.
- Isolating the wrong point or relying on a switch that can be re-closed.
- No lock-off, so the supply can be restored while work continues.
- Re-energising before the permit is cancelled and people are clear.
Document workflow
An electrical permit to work is typically raised under the wider permit to work system after a risk assessment, with an isolation permit and a lock-off applied first. Where live work is genuinely unavoidable, a separate live working permit is used instead.
See the related documents below for what is commonly required before, used with and completed after an electrical permit to work.
Retention (high level)
Completed electrical permits are usually kept for a period afterwards as a record of how the isolation was controlled, in line with the employer’s obligations and data-protection duties. This page does not state a period — confirm with the applicable law and the official authority.
Completing and sharing as a PDF
Electrical permits are commonly completed, signed and stored as PDFs and displayed at the work area. Exporting to PDF supports the record; it does not make the permit official or guarantee compliance.
Employer checklist
- Define which electrical work is permit-controlled and who may isolate.
- Ensure equipment is isolated, locked off and proved dead before work.
- Control return to service so nothing is re-energised too early.
- Keep completed permits as records and review after any incident.
Worker notes
- Do not touch the equipment until it is proved dead at your point of work.
- Work only within the limits the permit states.
- Never assume isolation — confirm the lock-off and proving before starting.
Country considerations
Rules on electrical isolation, competence and safe working vary by country, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not a guarantee of validity.
Confirm current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for safe electrical working, the competence of authorised and isolating persons, and compliance. This page is an educational overview with a template example; it does not authorise any work and does not transfer responsibility.
