We are a separate company

On 1 April Electricity Transmission became a legally separate company within the National Grid Group. Find out more about what this change means.

Electricity Safety Rules

The rules are mandatory. Everyone who works on or near to the transmission system is responsible for making sure they are thoroughly familiar with the detail of the relevant safety rules and appropriate supporting documents.

Safety documents

Our Electricity Safety Rules and National Safety Instructions are provided to make sure work can be carried out safely on or near electrical and mechanical equipment. We publish them for third-party companies with authorised staff, Distribution Network Operators (DNOs) and Generator Operators.

National Safety Instructions

Electricity authorisation training (competent/authorised person)

We provide essential primary safety training to our contractors who need access to high voltage compounds and routes. 

The scheme operates to satisfy the requirements of National Safety Instruction (NSI) 30 "Appointment of Persons". This procedure describes the process for the appointment of persons of both company and non-company personnel under the National Grid Safety Rules. 

The training for non-company personnel is administered by our Learning and Development department based in Eakring, Nottinghamshire.
