Safety. Authority. Confidence in Every Switch.

At HaLVE, our Senior Authorised Persons (SAPs) are trusted to manage and control High Voltage (HV) electrical systems with precision, professionalism, and full regulatory compliance. Whether supporting hospitals, industrial estates, or public infrastructure, our SAPs ensure your electrical network is operated and maintained to the highest standards.

What Is a Senior Authorised Person?

A Senior Authorised Person is responsible for the safe operation, isolation, and maintenance of HV systems—typically 11kV and above. SAPs are authorised to issue safety documentation, perform switching operations, and supervise works on or near HV equipment, ensuring safety and continuity at every stage.

Our SAP Services Include:

  • HV switching operations and isolation procedures
  • Issue of Permits to Work, Sanctions to Test, and Limitations of Access
  • Supervision of HV maintenance, testing, and commissioning
  • Fault diagnosis and emergency response
  • Liaison with Authorising Engineers and Distribution Network Operators (DNOs)
  • Support for AE audits and electrical safety documentation
  • Temporary or long-term SAP cover for projects or ongoing operations
  • Compliance with Electricity at Work Regulations 1989 and HTM 06-03 (for healthcare environments)

HTM 06-03 Compliance

In healthcare settings, our SAPs operate in full alignment with HTM 06-03, which outlines the safe management of electrical systems in hospitals and clinical environments. This includes:

  • Appointment and authorisation of SAPs and Authorised Persons
  • Use of safety documentation and switching schedules
  • Procedures for planned and emergency works
  • Ensuring resilience and continuity of supply in patient-critical areas
