This procurement, located primarily in the UK, is currently at the tender stage with significant milestones including an expression of interest deadline on 10th July 2026, with the enquiry period closing on 26th June 2026. This process involves a competitive flexible procedure as per the Procurement Act 2023 regulations and targets contractors for a service contract valued at a gross amount of £25.2 million. It's important to note this procurement emphasizes the repair and refurbishment of existing pumps rather than the purchase of new ones, promising a five-year contract with possible extensions up to 2034. This tender presents substantial opportunities for businesses specialising in marine equipment repair and maintenance services. Ideal candidates would own or have access to a testing facility for marine pumps and possess strong storage capabilities and a robust supply chain network to handle parts and materials. Companies excelling in technical reporting and cost estimation will find the procurement process advantageous, particularly SMEs that can meet the pass/fail conditions of participation. With the contract requiring expertise in producing health checks and technical surveys for naval submarine equipment, firms with experience in defence mechanisms and personnel with Facility Security Clearance would be well-suited to tap into and grow through this opportunity. ## Notice The planned procurement shall provide in-service support for Main Circulating Water Pumps (MCWPs) on board naval submarines. The primary body of work required will be the repair and refurbishment of existing pumps, for which it is essential that bidders either own or have unlimited access to a pump testing facility. Additionally, suppliers must have the storage capabilities to potentially accommodate several MCWPs at one time, as well as the supply-chain network to source its own parts and materials. This procurement is not anticipated to include within its scope the manufacture and purchase of new pumps. Potential suppliers must have the suitably qualified and experienced personnel to produce technical reports associated with health checks and strip and surveys, and the surveying capabilities to accurately estimate the cost and lead time of repairing pumps to an A1 standard. This procurement will be for a minimum 5-year contract term. The contract shall be competed under Procurement Act 2023 regulations and will be subject to the competitive flexible procedure. ### Lot Information Lot 1 Renewal: There will be a total of 2 extension years (1 + 1) available as options for the Authority to undertake at it's discretion. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/050564-2026 | | 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 | Planning, Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 29 May 2026 | | Submission deadline | 26 Jun 2026 | | Future notice date | 1 May 2026 | | Award date | Not specified | | Contract period | 1 Mar 2027 - 29 Feb 2032 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £21,000,000 | | Lots value | £21,000,000 | | 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 | SUBMARINE DELIVERY AGENCY | | Locality | BRISTOL | | Post town | Bristol | | Postcode | BS34 8JH | | Country | England | | ITL 1 | TLK South West (England) | | ITL 2 | TLK5 West of England | | ITL 3 | TLK52 Bath & North East Somerset and South Gloucestershire | | Local authority | South Gloucestershire | | Electoral ward | Stoke Park & Cheswick | | Westminster constituency | Filton and Bradley Stoke | | Delivery location | Not specified | ## CPV Codes ### Divisions - 42 - Industrial machinery - 50 - Repair and maintenance services ### Codes - 42122130 - Water pumps - 42122161 - Cooling-water pumps - 50240000 - Repair, maintenance and associated services related to marine and other equipment ## Release History - 29 May 2026 at 07:07 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/050564-2026 - 14 Nov 2025 at 10:06 - Planning - UK3 - Planned Procurement Notice - https://www.find-tender.service.gov.uk/Notice/073825-2025 - 13 Nov 2025 at 13:01 - Planning - UK1 - Pipeline Notice - https://www.find-tender.service.gov.uk/Notice/073519-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/050564-2026 29th May 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/073825-2025 14th November 2025 - Planned procurement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/073519-2025 13th November 2025 - Pipeline notice on Find a Tender ## Notice URLs - https://www.find-tender.service.gov.uk/Search - https://www.gov.uk/government/organisations/submarine-delivery-agency - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
