The Authorising Persons up to 11,000V course provides learners with the knowledge, skills, and competence required to safely manage and authorise work on high‑voltage electrical systems operating up to 11kV. This industry‑focused programme covers the essential responsibilities of an AP, ensuring candidates can implement safe systems of work, understand HV operational procedures, and correctly oversee switching, isolation, and permitting activities.
Through a blend of theory, practical demonstrations, and scenario based assessments, learners develop a deep understanding of HV equipment, network operation, risk control, and the critical decision‑making involved in authorising high‑voltage work. This course ensures that candidates are fully prepared to carry out duties in alignment with recognised HV safety rules and organisational procedures
