Current stage: Tender OCID: ocds-h6vhtk-06f87a [View canonical contract page](https://d3tenders.com/contract/?ocid=ocds-h6vhtk-06f87a) [Download OCDS JSON](https://d3tenders.com/contract/ocds-h6vhtk-06f87a.json) ## Summary Southern Water Services Limited is buying boundary boxes and associated components for its water distribution network. The requirement is divided into two supply areas: standard 25mm boundary boxes for reactive maintenance and smart-metering installation, and non-standard, multi-property and specialist boundary boxes for the same programmes. This is a goods contract for suppliers able to manufacture, distribute or otherwise provide these products in the required configurations. Deliveries and use are in South East England, supporting Southern Water’s network operations. The buyer is Southern Water Services Limited, a private utility based in Worthing. Businesses with product ranges covering both standard and specialist boundary boxes may find the requirement relevant, while firms supplying only unrelated water-infrastructure equipment are unlikely to be suitable. The process reached tender: Southern Water invited offers through an open procedure under the utilities regime. It has two lots, covering standard and non-standard boundary boxes, with suppliers able to bid for either or both. Questions could be submitted until 30 September 2026 at 17:00, and offers were due by 7 October 2026 at 17:00. The published estimated value is £0 for the procurement, and £0 for each lot. The contract is scheduled to run from 12 January 2027 to 11 January 2032, with an option to extend for three years to 10 January 2035. The buyer expected to complete its award decision by 11 January 2027. Evaluation is 70% technical quality and 30% commercial price. Economic selection uses PSQ requirements, with technical requirements set out in the ITT. This opportunity suits manufacturers, specialist distributors and established water-sector suppliers able to provide reliable boundary boxes and associated components in both standard and bespoke configurations. Relevant capability includes supplying 25mm standard boxes, multi-property units and specialist designs suitable for water distribution networks, reactive maintenance and smart-metering installation. Suppliers should be able to demonstrate economic standing against the PSQ requirements and meet the technical requirements in the ITT. The contract’s technical quality weighting makes product performance, technical compliance and the ability to support the stated operational uses important competitive factors, alongside commercial pricing. Firms with a dependable supply chain, sufficient production or sourcing capacity and experience delivering infrastructure components to a utility network are best placed to compete. ## Notice Supply of standard and non-standard boundary boxes. ### Lot Information Standard Boundary Boxes Supply of 25mm standard boundary boxes and associated components for use within Southern Water's water distribution network, supporting both reactive maintenance activities and smart metering installation programmes.
