## Summary

The procurement process for the contract titled "100760 Landulph Tertiary Connection" involves the PUBLIC utility contraction by the NATIONAL GRID ELECTRICITY TRANSMISSION PLC. This project, which falls under the works category, pertains to substation construction on a substantial scale across regions in the United Kingdom from UKC to UKK. The procurement is carefully executed at the award stage with significant urgency due to the insolvency of the previous contractor, Gunning Transmission & Distribution Services Limited (GTDS). The project is treated as a direct award, aiming at a seamless transition to maintain critical work schedules. The award to COSTAIN LIMITED was signed on the 30th of January 2026, with substantial works valued at £9.5 million to be completed by August 2027. The disruption caused by GTDS' administration was unforeseen, necessitating a swift contractual handover to preserve the continuity of the electricity transmission network's expansion.

This tender offers extensive opportunities for businesses specialising in infrastructure works, particularly those skilled in substation construction and energy sector enhancements. With careful risk management and the need for urgent yet strategic contract completion, businesses with robust project management and a strong supply chain can thrive in such influential projects. Large-scale service providers with a stable financial background, such as COSTAIN LIMITED, are ideal candidates to undertake similar projects, ensuring national infrastructure improvements while supporting the UK's transition to sustainable energy solutions. The procurement strategy demonstrates the critical role of experienced, highly capable contractors in meeting both regulatory and consumer demands within tight operational timelines.

## Notice

This contract relates to the delivery of works and related services at Landulph 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.

### Procurement Information

The Works are strictly necessary to continue the delivery of nationally significant infrastructure upgrades as part of the ongoing enhancement of the grid. By bringing on the replacement contractor almost immediately through this direct award, National Grid is seeking to minimise and mitigate the delay to the Works arising from the administration of GTDS and maintain continuity of the supply chain and otherwise secure continuity on site. National Grid intends to have the contract in place before the end of January 2026, so within 2 weeks of GTDS' administration. While some earlier contingency planning was possible, National Grid could not reasonably have commenced a competitive tendering procedure before GTDS' administration was confirmed and there is no time to run such a procedure between the date of administration and the required into-contract date. The urgency is unavoidable as it is attributable solely to the administration of GTDS which could not have been foreseen when the Works were allocated to GTDS and was not confirmed until 16 January. National Grid has explored other alternatives to this direct award, including the use of its existing frameworks and allocation through its construction dynamic purchasing system, but no other route was found to be suitable in the circumstances.
