SECMP0059 Amendments to SEC Security Assessments for Non-Domestic Suppliers and Other Users

Proposer Gordon Hextall
Lead Analyst SEC Change
Date raised 31/08/2018
Implementation date 28/02/2019 (February 2019 SEC Release)
Latest update This modification was implemented on 28 February 2019 (February 2019 SEC Release).

What is the issue?

This Modification seeks to provide clarity for non-domestic energy Suppliers on the type of User Security Assessment that is required for the second and third years after the initial Full User Security Assessment; and align security assessments for Other Users with the arrangements that currently apply to Small Suppliers to ensure proportionate assurance of the security risks.

What is the solution?

The SSC has considered the security risks that arise from the supply of energy to Non-Domestic Premises and has proposed that the threshold for the supply of Non-Domestic Premises determining the type of User Security Assessment Supplier Parties are subject to, be set at 50,000. To account for Supplier Parties that have a combined portfolio of Domestic Premises and Non-Domestic Premises, the SSC has proposed that these Supplier Parties use an equation to determine which User Security Assessments they should undergo. This equation considers the different levels of risk that different types of premises pose.

The SSC proposes that SEC Section G8.47 is amended to align it with the security profile of Supplier and Network Parties who supply gas or electricity to 250,000 or less Domestic Premises and that in year 2 of becoming a SEC Party, Other Users schedule a Verification User Security Assessment, instead of a User Security Self-Assessment.
