Membership of the ISLG is open to companies that are members of the infrastructure contractors and design community. Some ISLG member companies are also railway undertakings: the train operations aspect of their scope of operations is addressed by the M&EE Network Group. Each ISLG member must manage their own risks associated with their own scope of operations.

The Chair of ISLG (and individual members) represents the ISLG at industry meetings and forums which are relevant to the purpose and scope of the group. The Chair attends groups that include RSSB’s SSRG and Network Rail’s Infrastructure Projects Safety and Sustainability meeting.
