Scotia Gas Network Gas (SGN) group: decision to accept commitments offered

Case outcome

On 2 December 2025, following our statutory consultation, we have decided to accept the binding commitments from the SGN Group. We received one representation in response to our consultation, in support of the proposed commitments. The Commitments address the competition concerns that we had provisionally identified during the course of the investigation. The Commitments will take effect from the Effective Date, 2 December 2025, and will remain in force for a period of five years from that date. Ofgem notes that entering into of Commitments does not constitute a finding of any infringement(s) by Ofgem or the admission of any infringement(s) by the SGN Group.

Original enforcement case

On 8 March 2024, Ofgem opened an investigation into whether certain practices by the SGN Group infringed the Chapter II prohibition of the Competition Act 1998. Ofgem was concerned the SGN Group had engaged in conduct that may have abused its dominant position by refusing to adopt above 7 barg connections (these are higher pressure connections used at non-domestic premises) provided by third parties in the Scotia Gas Network Gas Distribution Network Area.

On 10 April 2025, the SGN Group initially submitted its formal Proposed Commitments (the ‘Proposed Commitments’) to Ofgem to address its competition concerns. After consideration of these commitments and further discussions with the SGN Group, a final revised set of Proposed Commitments was submitted by the SGN Group on 25 July 2025. The Proposed Commitments have been considered by Ofgem, and we sought written responses by 24 September 2025 before making a final decision on whether to accept them.
