All suppliers interested in this tender are advised to register on this platform.\nPlease see GBE-N's Linked In page (https://www.linkedin.com/company/great-british-nuclear/) for further information, and email any queries to oscommercial@greatbritishnuclear.uk." } ], "dueDate": [ { "releaseID": "079606-2026", "releaseDate": "2026-08-20T16:05:54+01:00", "releaseTag": [ "planning" ], "value": "2026-09-03T23:59:59+01:00" } ], "status": [ { "releaseID": "079606-2026", "releaseDate": "2026-08-20T16:05:54+01:00", "releaseTag": [ "planning" ], "value": "scheduled" } ] } ] }, "parties": [ { "id": "GB-PPON-PRCJ-2655-YDML", "name": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "Great British Energy - Nuclear" } ], "identifier": { "scheme": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "GB-PPON" } ], "id": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "PRCJ-2655-YDML" } ] }, "address": { "streetAddress": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "3-8 Whitehall Place" } ], "locality": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "London" } ], "postalCode": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "SW1A 2EG" } ], "country": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "GB" } ], "countryName": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "United Kingdom" } ], "region": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "UKI32" } ] }, "contactPoint": { "email": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "commercialcdp@greatbritishnuclear.uk" }, { "releaseID": "079214-2026", "releaseDate": "2026-08-19T17:13:34+01:00", "releaseTag": [ "planningUpdate" ], "value": "oscommercial@greatbritishnuclear.uk" } ] }, "roles": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": [ "buyer" ] } ], "details": { "url": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "https://www.greatbritishenergynuclear.uk" } ], "classifications": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": [ { "scheme": "UK_CA_TYPE", "id": "publicAuthoritySubCentralGovernment", "description": "Public authority - sub-central government" } ] } ] } } ], "buyer": { "id": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "GB-PPON-PRCJ-2655-YDML" } ], "name": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "Great British Energy - Nuclear" } ] }, "tender": { "id": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "ocds-h6vhtk-069fb5" } ], "legalBasis": { "id": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "2023/54" } ], "scheme": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "UKPGA" } ], "uri": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "https://www.legislation.gov.uk/ukpga/2023/54/contents" } ] }, "title": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "Early Works - Earthworks" }, { "releaseID": "079214-2026", "releaseDate": "2026-08-19T17:13:34+01:00", "releaseTag": [ "planningUpdate" ], "value": "Early Works – Civils, Infrastructure, Buildings & MEP and Earthworks" }, { "releaseID": "079606-2026", "releaseDate": "2026-08-20T16:05:54+01:00", "releaseTag": [ "planning" ], "value": "Early Works - Civils, Infrastructure, Buildings & MEP and Earthworks" } ], "description": [ { "releaseID": "047293-2026", "releaseDate": "2026-05-21T15:51:00+01:00", "releaseTag": [ "planning" ], "value": "This package encompasses key ground‑related enabling activities required to prepare the site for construction.
