This contract falls within the laboratory, optical, and precision equipment industry, specifically under the CPV code 38000000. The project entails an upgrade to the neutron powder diffraction facility at Daresbury Laboratory in the United Kingdom. The process initially commenced in August 2025 with an open procurement method. As of June 2026, the stage is at the contract amendment phase, which extends the contract end date to 31st July 2026. Key locations associated with this procurement include Swindon in Wiltshire, and ISIS STFC Rutherford Appleton Laboratory in Didcot, Oxfordshire. This tender presents substantial opportunities for businesses focused on laboratory and precision equipment, specifically those capable of handling large-scale construction and engineering components like vacuum vessels. Given the open procedure and the significant gross contract value of approximately £264,000, it is particularly suitable for large suppliers with experience in government contracts and supplying complex scientific instrumentation. Small and medium enterprises (SMEs) and organisations involved in such specialised fields can leverage participation to expand their footprints, enhance reputation, and potentially secure future government-related contracts. ## Notice HRPD-x (High-Resolution Neutron Powder Diffraction) project is an upgrade to the existing HRPD facility in Daresbury Laboratory. This upgrade will include a new non-magnetic sample tank, a new complement of detectors and a new building to house the larger and more capable instrument. The HRPD-x vacuum vessel is a central component of the instrument, and it consists of two main components: a large rectangular section and circular front end. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/058737-2026 | | Notice type | UK10 - Contract Change Notice | | Procurement type | Standard | | Procurement category | Goods | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | SME, VCSE | | Awardee scale | Large | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 23 Jun 2026 | | Submission deadline | 19 Sep 2025 | | Future notice date | Not specified | | Award date | 21 Oct 2025 | | Contract period | 14 Nov 2025 - 20 May 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £220,000 | | Lots value | £220,000 | | Awards value | £205,500 | | Contracts value | £205,500 | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | UK RESEARCH & INNOVATION (UKRI) | | Locality | SWINDON, WILTSHIRE | | Post town | Swindon | | Postcode | SN2 1FL | | Country | England | | ITL 1 | TLK South West (England) | | ITL 2 | TLK7 Gloucestershire and Wiltshire | | ITL 3 | TLK71 Swindon | | Local authority | Swindon | | Electoral ward | Rodbourne Cheney | | Westminster constituency | Swindon North | | Delivery location | TLD61 Warrington, TLJ14 Oxfordshire CC | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | CADINOX | ## CPV Codes ### Divisions - 38 - Laboratory, optical and precision equipments (excl. glasses) ### Codes - 38000000 - Laboratory, optical and precision equipments (excl. glasses) ## Release History - 23 Jun 2026 at 07:13 - ContractAmendment - UK10 - Contract Change Notice - https://www.find-tender.service.gov.uk/Notice/058737-2026 - 19 Dec 2025 at 09:54 - Award - UK7 - Contract Details Notice - https://www.find-tender.service.gov.uk/Notice/084724-2025 - 23 Oct 2025 at 12:05 - Award - UK6 - Contract Award Notice - https://www.find-tender.service.gov.uk/Notice/067800-2025 - 4 Sep 2025 at 08:49 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/053773-2025 - 6 Aug 2025 at 07:45 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/046351-2025 - 6 Aug 2025 at 07:44 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/046350-2025 - 5 Aug 2025 at 13:04 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/046143-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/058737-2026 23rd June 2026 - Contract change notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/084724-2025 19th December 2025 - Contract details notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/067800-2025 23rd October 2025 - Contract award notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/053773-2025 4th September 2025 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/046351-2025 6th August 2025 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/046350-2025 6th August 2025 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/046143-2025 5th August 2025 - Tender notice on Find a Tender ## Notice URLs - http://www.cadinox.com - https://ukri2.my.salesforce-sites.com/ProSpend__CS_ContractPage?SearchType=Projects&uid=a1MTm000007FrBGMA0&searchStr=&sortStr=Recently+Published&page=1&filters=&County= - https://ukri2.my.site.com - https://www.legislation.gov.uk/ukpga/2023/54/contents - https://www.ukri.org/ ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
