The procurement, valued at up to £780 million, is categorised under 'works' in the defence and security sector, and involves upgrading various electrical components and installations. Located in Reading, United Kingdom, the initiative is currently at the tender stage, with the tendering process open until 5th March 2026. Key dates include a deadline for submission of the non-disclosure agreement and tender security questionnaire by 23rd January 2026, and the Invitation to Participate is expected to be released on 26th January 2026. This tender represents a substantial opportunity for businesses specialising in electrical infrastructure projects, particularly those with experience in high-security environments. The framework will select two partners based on a competitive flexible procedure that evaluates both the commercial and technical merit of bids, with particular emphasis on quality, capability, and sustainability. This long-term contract extends over a maximum of 15 years, offering a stable and secure avenue for business growth, enabling suppliers to benefit from consistent demand for innovative and resilient infrastructure solutions. Companies with robust technical expertise in electrical distribution, site preparation, and substation construction would find this tender particularly aligned with their skill sets. ## Notice AWE Plc ("AWE") is embarking on a critical transformation of its infrastructure as part of the national endeavour to support the UK's nuclear deterrent and has been refining and formalising a new approach to infrastructure delivery, designed to drive greater consistency, pace, and long-term value. This model is being largely implemented via 3 programmes: - Future Materials Campus: A programme to renew existing facilities for the manufacture of nuclear components, storage of nuclear materials, provide improved science and analysis capabilities, and invest in new capabilities for nuclear material recovery. - Future Infrastructure Programme: a programme that focuses on delivering wider infrastructure needs e.g. new office accommodation; laboratories; testing facilities, site services, and advanced manufacturing facilities. - Estates and Liabilities management: on-going liabilities management to run programmes that safely decommission and demolish legacy facilities and manage generated waste via seeking suppliers with experience of the same. This framework focuses on upgrading the electrical network under FIP, with the possibility of some works supporting the Future Materials Campus. Strategic aspirations are to upgrade and modernise AWE's electrical network infrastructure, improve network resilience and obsolescence management, to benefit from modern standards and requirements, while reducing the cost base of new infrastructure. The Electrical Infrastructure Upgrade Programme will grow significantly over the coming years, and AWE looks to appoint 2 partners through this procurement, with the capacity and capability to meet the programme's increasing demand. The Framework is a zero-value contract against which AWE may call off work for the Electrical Infrastructure Upgrade programme. The Framework will provide no guarantee of any work to any Supplier, it is a contract mechanism against which AWE may (but is not obliged) to call off work from the relevant Supplier for the Electrical Infrastructure Upgrade Framework. Full Framework Information "ITP Volume 2 Framework Specification" will be available to Suppliers that have registered and been granted access, as below. AWE will award a place on the Framework to the 2 highest scoring suppliers, that offer the most advantageous tenders that is, the tenders that balance price with quality, technical capability, and sustainability. There will be a transparent mechanism to award work under the Framework as set out in the procurement documents Bidders should download, complete and sign the Electrical Infrastructure Non-Disclosure Agreement and Tender Security Questionnaire available from the Defence Sourcing Portal here https://contracts.mod.uk/esop/guest/go/opportunity/detail?opportunityId=60647 and return these by email to: electricalinfrastructure@awe.co.uk. The deadline for submission of these documents is 12:00 on 23rd January 2026 in order to gain access to the Invitation to Participate and associated procurement documents. Once AWE has reviewed and signed the documents where appropriate, Bidders will be invited to the Invitation to Participate stage of the procurement where they will have access to the detailed documentation.
