Description

This contract relates to the delivery of works and related services at Amersham Substation (the "Works"). The Works were previously allocated to Gunning Transmission & Distribution Services Limited - in Administration ("GTDS"). GTDS went into administration on Friday 16 January 2026 and is unable to progress or complete delivery of the Works. As a consequence, National Grid has had to move at significant pace to appoint a replacement contractor for the Works, to progress critical path activities, maintain (as far as practicable) the programme for the works, and satisfy regulatory, customer and other commitments. The Works contribute to the ongoing expansion of the electricity transmission network, delivering essential upgrades to the grid to support the UK's move away from fossil fuels and increased clean energy generation. Various other projects are also being re-allocated to other contractors for similar reasons, while the delivery of further works (previously allocated to GTDS) is being supported by National Grid's existing framework contractors.
