The industry category involves works related to cooling and ventilation equipment, specifically targeting installations within Oxfordshire, UK. This tender represents a significant opportunity for businesses specialising in HVAC installation and cooling systems technology. SMEs with expertise in the design, manufacture, and integration of water chiller systems would find this contract particularly relevant, as it focuses on enhancing the cooling circuits for high voltage power supplies on existing infrastructure. The ability to meet technical criteria, deliver effective programme management, and ensure quality assurance are crucial for competing effectively, with a notable emphasis on commercial criteria driven by price competitiveness. As the procurement process was conducted via open competition, it encouraged participation from various capable suppliers, thereby fostering business growth and potential collaboration within the cooling technology sector. Companies with focus on providing social value through their performance would also align well with the procurement objectives set by UKAEA during this process. ## Notice UKAEA has a requirement for the design, manufacture, testing, delivery, installation, and commissioning of a new water chiller system to provide primary circuit cooling for the D15 High Voltage Power Supply equipment used on MAST-U. ### Planning Information https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=98866&B= ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/038383-2026 | | Notice type | UK7 - Contract Details Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Open | | Procurement method details | Below threshold - open competition | | Tender suitability | SME, VCSE | | Awardee scale | SME | | All stages | Planning, Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 28 Apr 2026 | | Submission deadline | 2 Jan 2026 | | Future notice date | 17 Nov 2025 | | Award date | 24 Apr 2026 | | Contract period | 24 Apr 2026 - 31 Dec 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £150,000 | | Lots value | £150,000 | | Awards value | Not specified | | Contracts value | £104,453 | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | UK ATOMIC ENERGY AUTHORITY | | Locality | OXFORDSHIRE | | Post town | 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 | TLJ14 Oxfordshire CC | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | COOL-THERM (UK | ## CPV Codes ### Divisions - 42 - Industrial machinery - 45 - Construction work ### Codes - 42500000 - Cooling and ventilation equipment - 42510000 - Heat-exchange units, air-conditioning and refrigerating equipment, and filtering machinery - 45331000 - Heating, ventilation and air-conditioning installation work ## Release History - 28 Apr 2026 at 09:30 - Award - UK7 - Contract Details Notice - https://www.find-tender.service.gov.uk/Notice/038383-2026 - 11 Nov 2025 at 14:30 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/072840-2025 - 9 Oct 2025 at 07:30 - PlanningUpdate - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/063516-2025 - 8 Oct 2025 at 15:00 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/063414-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/038383-2026 28th April 2026 - Contract details notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/072840-2025 11th November 2025 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/063516-2025 9th October 2025 - Preliminary market engagement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/063414-2025 8th October 2025 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=98866&B= - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=99863&B= - https://www.gov.uk/government/organisations/uk-atomic-energy-authority - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
