The requirement covers microwave tubes and equipment, microwave equipment, and associated engineering design. The work is to be delivered in the United Kingdom and relates to fusion-energy infrastructure. It will suit businesses able to develop and engineer specialised transmission systems for demanding scientific or industrial applications, particularly where microwave technologies and integration with existing transmission lines are core capabilities. The buyer is a public undertaking based at Culham Campus in Abingdon. The procurement is categorised as services, with the requirement structured as a single lot and identified as suitable for small and medium-sized enterprises. The process reached tender: the buyer invited offers through a selective competitive flexible procedure. It has two stages: a pre-selection questionnaire (PSQ), followed by an invitation to tender (ITT). Enquiries were due by 22 September 2026 at 17:00, and expressions of interest were due by 9 October 2026 at 12:00. The intended award decision period ends on 16 October 2026 at 23:59. The contract is scheduled to run from 4 January 2027 to 31 August 2029. The published gross value is £0, including VAT. Electronic submission is allowed and responses must be in English. The PSQ uses pass/fail and scored assessment. The procurement is above the relevant threshold. This opportunity suits specialist engineering businesses with the ability to design and assess the manufacturability of novel transmission systems, especially those working with microwave tubes, microwave equipment and related transmission technologies. Strong candidates are likely to have experience translating advanced engineering concepts into manufacturable designs and integrating new systems into established experimental or industrial infrastructure. Knowledge of fusion-energy facilities, high-performance scientific equipment or comparable complex transmission-line environments would be relevant to the stated purpose. The work may also suit smaller specialist firms, since the single lot is identified as suitable for SMEs. Businesses should be prepared to demonstrate their capability through the pre-selection questionnaire before progressing to the invitation-to-tender stage, with assessment based on pass/fail requirements and scored responses. ## Notice UKFE is seeking to progress the design and manufacturability of a novel transmission system that is planned to be integrated into the MAST-U EBW transmission line ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/085974-2026 | | Notice type | UK4 - Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Selective | | Procurement method details | Competitive flexible procedure | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 10 Sep 2026 | | Submission deadline | Not specified | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 4 Jan 2027 - 31 Aug 2029 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | 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 | UK Industrial Fusion Solutions Ltd | | Locality | ABINGDON | | Postcode area | Oxford | | Postcode | OX14 3DB | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ1 Berkshire, Buckinghamshire and Oxfordshire | | ITL 3 | TLJ14 Oxfordshire CC | | Local authority | South Oxfordshire | | Electoral ward | Sandford & the Wittenhams | | Westminster constituency | Didcot and Wantage | | Delivery location | Not specified | ## CPV Codes ### Divisions - 31 - Electrical machinery, apparatus, equipment and consumables; lighting - 71 - Architectural, construction, engineering and inspection services ### Codes - 31711420 - Microwave tubes and equipment - 31711422 - Microwave equipment - 71320000 - Engineering design services ## Release History - 10 Sep 2026 at 14:58 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/085974-2026 - 10 Sep 2026 at 11:26 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/085771-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/085974-2026 10th September 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/085771-2026 10th September 2026 - Tender notice on Find a Tender ## Notice URLs - https://ukfe.delta-esourcing.com/respond/4DR2B5Q4SU - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
