The industry category is engineering design services with specialties in electrical power systems and plant engineering. The initial stage of the procurement is planning, with opportunities for preliminary market engagement exercises expected to commence in November 2025. Key activities include a questionnaire submission deadline on 6 November 2025 and an indicative online presentation and Q&A session in the week beginning 24 November 2025. Although the process is still in the planning stage, it seeks to refine specifications and gather market insights to shape future approaches and documentation. This tender presents significant opportunities for businesses specialising in engineering design, particularly in the fields of CO2 processing, power systems, and plant engineering, offering the chance to influence the project scope and requirements. Companies with expertise in high-pressure and thermal dynamics, those who can innovate or provide novel technologies in cooling systems, and those complying with UK pressure equipment regulations are well-suited to compete. Engaging early in the market engagement phase allows businesses to shape potential contract terms and criteria, paving the way for future procurement opportunities as the project progresses. This presents a valuable opportunity for engagement and growth for businesses with the capability to meet high technical standards and regulations. ## Notice The following summary is not intended as a complete or definitive specification of the requirement. A purpose of this engagement notice is to seek information from the market to help refine our understanding and aid the development of a future specification. UKIFS is seeking experts to support the design and development of a CO2 condenser that is part of the STEP power cycle. This is because a high-performance CO2 condenser is critical to the efficiency of the STEP powerplant (supercritical and/or transcritical CO2 power generation cycles are currently the preferred concept for the STEP prototypic plant). The proposed technical and operating conditions of the proposed CO2 condenser are: *Operating pressure is between ca. 60-100 bar for the CO2 stream *Operating inlet temperature will be between ca. 50 - 110degC. The outlet temperature will be between ca. 20-25 degC for the CO2 stream. *Thermal duty is in the range of 1-2 GWth. *The equipment must comply with UK pressure equipment regulations. Note: both wet and dry cooling options are of interest, as are both existing and novel technologies or design approaches.

The engagement is currently expected to take place in two stages: The first stage involves a written submission via the questionnaire, which should be returned by 13:00 hrs on 6 November 2025. The second stage will be an online presentation (delivered by UKIFS) and Q&A session that multiple suppliers may attend. This is expected to take place during the week commencing 24 November 2025 (indicative only). For the avoidance of doubt: Suppliers who wish to attend the presentation and Q&A session will need to confirm that they wish to participate by indicating this within the questionnaire and submitting this via Delta as directed. Supplier's who do not to respond to this notice are NOT thereby excluded from any subsequent tender process for this workstream. As part of this PME, UKIFS may carry out a range of activities. These may include, but are not limited to: issuing follow-up questions to suppliers and reviewing their responses; engaging in discussions with suppliers either collectively or individually, such as through webinars or workshops; seeking feedback on proposed requirements; exploring procurement approaches; identifying potentially suitable suppliers; assessing market capacity; and discussing possible contractual terms. PME may also be used to support the development of award criteria and the refinement of tender documentation. Any information provided in this notice, such as CPV codes, estimated contract values, anticipated contract dates and durations, and proposed engagement timelines - are indicative only and based on UKIFS’s current understanding. These details may be subject to change. The purpose of PME is to improve our understanding of the market, refine our requirements, and shape our procurement strategy. The list of activities included here is illustrative rather than exhaustive, and the nature, extent and timetable of engagement may evolve in line with UKIFS’s needs. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/063751-2025 | | Notice type | UK2 - Preliminary Market Engagement Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 9 Oct 2025 | | Submission deadline | Not specified | | Future notice date | 6 Nov 2025 | | Award date | Not specified | | Contract period | 31 Mar 2026 - 31 Mar 2027 | | 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 | Planning | | Lots status | Planning | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UK INDUSTRIAL FUSION SOLUTIONS LTD | | Locality | ABINGDON | | 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 | Not specified | ## CPV Codes ### Divisions - 71 - Architectural, construction, engineering and inspection services ### Codes - 71320000 - Engineering design services - 71323100 - Electrical power systems design services - 71323200 - Plant engineering design services ## Release History - 9 Oct 2025 at 13:05 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/063751-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/063751-2025 9th October 2025 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://ukifs.delta-esourcing.com/respond/2HE569TDE9 - https://ukifs.delta-esourcing.com/tenders/UK-UK-Abingdon:-Engineering-design-services./2HE569TDE9 - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
