UK5 - Transparency Notice
Summary of the contracting process

Southern Water Services Limited procured hydraulic modelling verification services under the title Hydraulic Model Verification. The work sits within technical testing, analysis and consultancy, and concerns verification of hydraulic models. The requirement is presented as a single lot and is classified as a service. Delivery is in the United Kingdom; no more specific delivery place is identified in the procurement details. The buyer is Southern Water Services Limited, a water utility based in Worthing. The requirement is a specialist technical service rather than the supply of physical goods or construction works, and is relevant to consultancies and engineering firms with expertise in checking hydraulic models for a water-sector client.

The procurement is complete and has been awarded through a direct award. Southern Water cited limited current market capacity to fulfil the requirement and urgency as the rationale. Hydraulic Analysis Limited was selected for the single lot. The award value is £1,194,000 excluding VAT, or £1,432,800 including VAT. The awarded contract period runs from 19 October 2026 to 30 April 2027. The award was recorded on 6 October 2026; the planned signature date was 16 October 2026. The service is above the applicable threshold. The lot was identified as suitable for small and medium-sized enterprises. The procurement details do not set out a scored evaluation basis or further eligibility conditions.

This award shows that Southern Water buys specialist hydraulic-model verification as a substantial, focused consultancy service, and that the requirement was placed by direct award because the buyer judged available market capacity to be limited. A credible competitor for a future requirement would need demonstrable capability in hydraulic modelling and independent verification, with the technical expertise and delivery capacity to meet a water utility’s needs. The selected supplier is an SME, and the lot was considered suitable for SMEs, indicating that this type of work need not be confined to large firms. Firms with relevant modelling, testing and analytical experience, and the ability to resource verification work promptly, are best placed to compete if this specific requirement returns to the market.
