## Summary

National Grid UK Limited is seeking works contractors for excavation, cable laying and reinstatement on the Isles of Scilly. The requirement covers both planned and reactive work, providing continuity and coverage across the islands. The primary activities are excavation, reinstatement and installation of low-voltage, 11kV and 33kV cables, as instructed by NGED in its South West – Isle of Scilly region. Work will be delivered in the Isles of Scilly, within the utility’s electricity network. The procurement is categorised as works, with cable-laying installation as the principal activity. It is intended for a contractor able to respond to scheduled programmes and unplanned requirements and to deliver associated excavation and reinstatement works in an island setting.

The procurement has reached tender: National Grid invited offers through a below-threshold open competition. It is a single-lot requirement under a closed framework agreement, with one participant and competition reopened for work issued under the agreement. Enquiries were due by 11 September 2026 at 17:00, and tender responses were due by 25 September 2026 at 17:00. The contract period is 1 March 2027 to 31 August 2033, with renewal described as 2.5 + 2.5 and a maximum end date of 31 August 2038. The estimated gross value is £1,800,000. Evaluation is weighted 60% technical quality and 40% commercial terms. Expressions of interest and SAP Ariba onboarding are required before tender documents are issued.

This opportunity suits contractors with established capability in utility excavation, cable installation and surface reinstatement, particularly at low voltage, 11kV and 33kV. Experience of both planned programmes and reactive network work is relevant, as is the capacity to provide continuity and coverage for an island electricity network. Suppliers should be able to mobilise suitable plant, labour and specialist cable-laying skills, manage work issued against a schedule of rates, and complete reinstatement to the required standard. The technical element carries greater evaluation weight than the commercial element, so evidence of dependable delivery, safe working, technical competence and effective response arrangements will be important. Contractors must also be able to work through National Grid’s electronic sourcing and onboarding process.
