The role involves providing technical, commercial, and project management expertise. The procurement, under the Competitive Flexible Procedure as per the Procurement Act 2023, was updated on 29th June 2026 and is currently in the tender stage of progress. The contract's estimated value is £1,080,000,000, inclusive of VAT, with an anticipated contract period from September 2027 to September 2041. This opportunity is situated in London, United Kingdom, with services primarily related to civil engineering consultancy and infrastructure support, among others. The call for tenders will close on 6th August 2026, while the final award period is set to end on 16th September 2026. This tender represents a significant opportunity for businesses specialising in infrastructure consultancy, project management, civil engineering, and environmental assessments. It is particularly suitable for firms with strong technical capabilities and experience in handling complex projects, potentially structured as joint ventures or consortia to meet the outlined requirements. Participating firms will benefit from a 14-year contract term, which offers stability and potential business growth. The competitive nature of the procurement process, which includes multiple stages of evaluation, allows firms to showcase their expertise and secure a substantial share of future infrastructure projects. Furthermore, the opportunity for future renewals and additional services enhances the potential for long-term collaboration and development within the energy sector. ## Notice The Delivery Partner (DP) will be responsible for supporting the development and delivery of the programme, providing technical, commercial and project management capability to ensure effective planning, risk management and delivery of defined outcomes. The estimated value is PS1,080,000,000 inclusive of VAT based on the contracting authority's current assumptions regarding programme scope, delivery profile, and resource requirements over the contract term. Due to the evolving nature of the programme and the length of contract, envisaged at 14 years, the volume and value of services required may vary over time. The stated value therefore represents an estimated total potential spend rather than a committed or guaranteed amount. In addition, progression through design stages and associated milestones or gates will determine the timing and extent of services required, potentially influencing the overall contract value over time. This estimate has been prepared in accordance with the valuation principles set out in the Procurement Act 2023. ### Lot Information Lot 1 Renewal: Due to the evolving nature of the programme and the length of contract, the volume and value of services required may vary over time. Additional units (subject to further approvals) represent a future option for GBE-N to instruct the Delivery Partner to support additional SMR deployments beyond the initial scope, delivered via contractually defined call-off mechanisms to ensure flexibility, transparency and compliance. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/060917-2026 | | Notice type | UK4 - Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Competitive flexible procedure | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 29 Jun 2026 | | Submission deadline | 6 Aug 2026 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 31 Aug 2027 - 1 Sep 2041 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £900,000,000 | | Lots value | £900,000,000 | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Active | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | GREAT BRITISH ENERGY - NUCLEAR | | Locality | LONDON | | Post town | South West London | | Postcode | SW1A 2EG | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 71 - Architectural, construction, engineering and inspection services - 72 - IT services: consulting, software development, Internet and support - 79 - Business services: law, marketing, consulting, recruitment, printing and security ### Codes - 71311100 - Civil engineering support services - 71311300 - Infrastructure works consultancy services - 71313400 - Environmental impact assessment for construction - 71313410 - Risk or hazard assessment for construction - 71313420 - Environmental standards for construction - 71313430 - Environmental indicators analysis for construction - 71313440 - Environmental Impact Assessment (EIA) services for construction - 71313450 - Environmental monitoring for construction - 71520000 - Construction supervision services - 71530000 - Construction consultancy services - 71540000 - Construction management services - 72224000 - Project management consultancy services - 79418000 - Procurement consultancy services ## Release History - 29 Jun 2026 at 15:39 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/060917-2026 - 29 Jun 2026 at 15:02 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/060889-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/060917-2026 29th June 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/060889-2026 29th June 2026 - Tender notice on Find a Tender ## Notice URLs - https://beisgroup.ukp.app.jaggaer.com - https://beisgroup.ukp.app.jaggaer.com/ - https://beisgroup.ukp.app.jaggaer.com/go/24059296019EF9ADECD4 - https://jaggaer.my.site.com/SupplierSupportRequest/ - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
