The requirement is for IT consultancy, software development, internet and support services (CPV 72000000), focused on changing and rationalising the water company’s data centre estate. The anticipated scope includes technical and delivery approaches, technology options, innovation, and potentially supporting the movement towards a more efficient data centre operating model. Southern Water is also considering how the requirement should be packaged into lots. The work would support Southern Water’s operations in England, with the buyer based in Worthing. This is a utilities-sector programme intended to shape a future sourcing exercise rather than a current tender for immediate delivery. This procurement is at the planning and preliminary market-engagement stage: Southern Water is seeking information before deciding its sourcing strategy and eventual procurement approach. Interested organisations are invited to respond through Southern Water’s Coupa Sourcing Portal by 23 September 2026. The buyer expects the future contract period to run from 1 October 2027 to 30 September 2031. The published procurement value is £0 gross, indicating that no contract value has been established at this stage. The planned requirement is above the relevant threshold and is expected to use a services procurement in the utilities sector. There is one planned lot, although Southern Water is specifically seeking market views on the most suitable lotting approach. The engagement will test the realism of the proposed delivery timescale and inform the business case. This engagement will suit organisations able to deliver complex data centre transformation, consolidation or rationalisation programmes for large utility or other critical-infrastructure environments. Southern Water is looking for evidence of market capability, capacity and appetite, so established delivery teams with sufficient resources for a multi-year programme should prepare relevant credentials. Useful contributions will include practical delivery models, technical options, innovative approaches, indicative commercial models and case studies from comparable work. Suppliers with experience advising on data centre strategy, designing target estates, migrating or modernising infrastructure, and supporting operating-model change are likely to be well placed to contribute. Businesses able to explain realistic implementation timescales and recommend an effective packaging or lotting structure should also find the engagement relevant. This is preparation for a possible future procurement, not an opportunity to bid for a contract now. ## Notice Southern Water is developing a programme to transform and rationalise its data centre estate. This Request for Information (RFI) is a preliminary market engagement exercise under the Procurement Act 2023, intended to inform and shape the emerging vision ahead of any procurement. Through it, Southern Water is seeking to: * Understand the capability, capacity and appetite of the market to deliver a programme of this nature; * Test the feasibility and realism of the emerging vision, and in particular the delivery timescale; * Gather delivery approaches, technical options, innovations, case studies and indicative commercial models; * Understand how the market would best package (Lot) the requirement; and * Inform Southern Water's business case, sourcing strategy and eventual procurement approach. ### Planning Information Any interested parties can respond via Southern Water's Sourcing Portal (Coupa): https://supplier.coupahost.com/quotes/public_events?customer=southernwater&company_name=Southern+Water ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/084383-2026 | | 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 | 7 Sep 2026 | | Submission deadline | Not specified | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 1 Oct 2027 - 30 Sep 2031 | | 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 | Southern Water Services Ltd. | | Locality | WORTHING | | Postcode area | Brighton | | Postcode | BN13 3NX | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ2 Surrey, East and West Sussex | | ITL 3 | TLJ27 West Sussex (South West) | | Local authority | Worthing | | Electoral ward | Northbrook | | Westminster constituency | Worthing West | | Delivery location | Not specified | ## CPV Codes ### Divisions - 72 - IT services: consulting, software development, Internet and support ### Codes - 72000000 - IT services: consulting, software development, Internet and support ## Release History - 7 Sep 2026 at 12:57 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/084383-2026 - 2 Sep 2026 at 09:58 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/082926-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/084383-2026 7th September 2026 - Preliminary market engagement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/082926-2026 2nd September 2026 - Preliminary market engagement notice on Find a Tender ## Notice URLs - http://www.southernwater.co.uk - https://supplier.coupahost.com/quotes/public_events?customer=southernwater&company_name=Southern+Water - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
