## Summary

National Grid Electricity Distribution plc intends to buy prefabricated glass-reinforced plastic (GRP) and anti-vandal steel enclosures, roofs and doors for outdoor-rated equipment in secondary substations. The goods will support NGED electricity networks operating at 11kV and 6.6kV. The procurement is divided into two lots: GRP enclosures, and anti-vandal steel enclosures. Products under both lots are intended for delivery across NGED sites in the Midlands, South West and South Wales. The requirement is for goods, including prefabricated substation structures and associated doors and roofs. Suppliers will need to work to NGED’s EE19 specification, which the buyer says will be shared when the tender reaches the market.

This is a planned procurement: the buyer has stated an intention to procure but has not yet invited tenders. It expects to use a selective competitive flexible procedure for a utilities procurement, with a framework agreement. Suppliers are expected to be able to express interest by 18 November 2026, with the tender notice anticipated by 13 November 2026. The buyer expects to complete evaluation and award by 7 June 2027. Both lots are planned to run from 1 August 2027 to 31 July 2030. The two lots cover GRP enclosures and anti-vandal steel enclosures respectively, with the same geographical coverage and substation voltage requirements. Tender documents are expected to be issued to interested suppliers through SAP Ariba after the tender notice.

This requirement is likely to suit manufacturers and specialist suppliers of GRP or anti-vandal steel enclosures for electrical infrastructure, particularly businesses able to provide complete enclosures with matching roofs and doors. Relevant preparation includes demonstrating the ability to design or manufacture products for outdoor-rated secondary substations on electricity distribution networks at 11kV and 6.6kV. Suppliers should be ready to work to NGED’s EE19 specification when it becomes available and to support delivery across the Midlands, South West and South Wales. Businesses with capacity to supply either material type can assess the corresponding lot, while firms able to provide both may consider both lots. The procurement is not yet at tender stage, so suppliers should prepare for the expected expression-of-interest process.
