Our structure



About the Group

In March 2022, National Grid plc announced its intention to sell a 60% equity stake in the Gas Transmission and Metering business to a consortium led by Macquarie and British Columbia Investment Management Corporation.

The completion of the sale to a newly created holding company structure took place on 31 January 2023. Following completion of the sale the Company began to operate under a new name, National Gas Transmission plc. On 11 March 2024, National Grid completed the sale of a further 20% in the business to the existing consortium.
