CERTIFIED ROLES & RESPONSIBILITIES
ELECTRICAL SAFETY GOVERNANCE & ROLES
Delivering qualified High Voltage (HV) and Low Voltage (LV) engineering personnel to enforce strict safety rules and operational compliance across client estates.
Senior Authorised Persons (SAP)
Fully qualified SAP engineers responsible for high-voltage system control, issuing Permits to Work (PTW), Sanctions for Test (SFT), Limitation of Access (LOA), and executing complex HV switching schedules.
Authorised Persons (AP)
Designated AP personnel providing day-to-day operational control, safety isolations, fuse removal, and supervised access management across designated HV and LV switchroom environments.
Electrical Duty Holder Support
Strategic advice and legal support for facility directors, ensuring site operations fully comply with the Electricity at Work Regulations 1989 and Health & Safety Executive (HSE) directives.
STATUTORY COMPLIANCE & RISK
ELIMINATE LIABILITY WITH CERTIFIED SAFETY MANAGEMENT
Operating high-voltage electrical networks without appropriately trained and appointed personnel creates severe safety risks, operational liabilities, and direct breaches of statutory legislation. Many site owners lack in-house, fully certified SAP engineers to execute safe isolations or oversee specialist contractor works.
MET Group supplies experienced, fully vetted Senior Authorised Persons and Authorised Persons to manage switching, issue formal safety documentation, and maintain complete compliance—allowing you to execute intrusive maintenance safely without holding permanent HV operational overheads.
OPERATIONAL DELIVERABLES
HIGH VOLTAGE SAFE SYSTEMS OF WORK
Rigorous execution protocols to guarantee zero-harm environments during high-voltage switching, maintenance, and fault interventions.
01
SWITCHING SCHEDULES & ISOLATIONS
Preparation, independent verification, and live execution of multi-stage high-voltage switching programmes to ensure complete electrical isolation prior to physical contractor access.
03
SAFETY RULES AUDITS & IMPLEMENTATION
Comprehensive review and authoring of site-specific High Voltage Safety Rules (HVSR), single line diagrams (SLDs), and emergency response procedures for client estates.
02
SAFETY DOCUMENTATION & PERMITS
Formal issuance of statutory safety documentation including Permits to Work, Sanctions for Testing, and Certificates of Isolation compliant with model safety rules.
04
CONTRACTOR SUPERVISION & ESCORTAGE
On-site technical supervision of third-party specialist contractors within HV switchrooms and substations, verifying arc-flash precautions and task risk assessments (RAMS).
SECTOR APPLICATION
TAILORED GOVERNANCE FOR COMPLEX ESTATES
Providing qualified SAP/AP coverage across mission-critical, commercial, and industrial HV infrastructure.
Data Centres & Telecommunications
Precision switching execution across dual-path HV feeds, generator synchronisation networks, and transformer substations with zero risk to continuous IT uptime.
Healthcare & NHS Trusts
Strict adherence to Health Technical Memoranda (HTM 06-02/06-03) guidance, supplying certified APs for hospital high-voltage networks and standby power systems.
Industrial & Manufacturing Parks
Flexible SAP cover for planned shutdown periods, private HV network expansions, and statutory 11kV/33kV maintenance routines.
