The Independent Stakeholder Group (ISG) (previously called the CEG and CSEG) has been set up to challenge us as we shape and deliver our business plans. They played an important role in the development of our current RIIO-GD2 business plans, providing feedback and challenge throughout the planning process. Their assessment of our final plan is included in the Final CEG Report
We will shortly be embarking on our business planning for RIIO-GD3, our next regulatory price control period, starting in April 2026.
The group is chaired by Maxine Frerk, who brings with her a wealth of experience from her 15 years at Ofgem. Most recently, Maxine was a member of Ofgem’s executive board, responsible for all aspects of regulation of the gas and electricity distribution networks.
To reflect the different needs and perspectives of local stakeholders in both our network areas, Maxine is joined by a range of stakeholder experts from across Scotland and the south of England, reflecting specialisms such as customer research, business users, future consumers and vulnerable customers. Together, the group ensures that we capture and act on the views of a range of customer and stakeholder groups in developing our current and future business planning. If you’d like to contact the ISG, please email engagement@sgn.co.uk.
