Electrical permits to work control all activities involving electrical systems on construction sites.
They are required for isolation, testing, commissioning, cable jointing, and live proximity work.
The permit defines the exact equipment, isolation points, and safety measures required.
Only an authorised person may issue and cancel an electrical permit to work.
The Electricity at Work Regulations 1989 require safe systems of work for electrical activities.
A permit ensures circuits are isolated, locked off, proved dead, and earthed where required.
Permits must be displayed at the point of work so all personnel can see the controls.
Cross-referencing with other permits is essential where electrical work overlaps other activities.
Permits have defined time limits — work must stop if the time limit expires.
Cancellation must only happen after all tools and personnel are clear of the circuit.

Prevent electrocution	Electrical contact kills — permits ensure circuits are confirmed dead before work.
Legal requirement	The Electricity at Work Regulations require documented safe systems for electrical work.
Clear communication	Permits ensure everyone knows what is isolated and what is safe.
Audit trail	Permits create a record of controls applied, providing evidence of compliance.
