Summary of the contracting process

United Utilities Water Limited, a private utility company based in Great Sankey, UK, has completed a procurement process concerning 'Wastewater Nitrous Oxide in Liquid Sensors and Controllers.' The buying organisation sought to acquire sensor equipment capable of detecting and measuring nitrous oxide specifically in liquid form, a requirement not met by gas state sensors. The procurement process was conducted via direct award due to the exclusive availability of the product from Unisense Environment A/S. The award was finalised on 1st August 2025, with the contract period set to commence on 16th September 2025 and run until 15th September 2030. The gross contract value is approximately £2.4 million, including consumables post the initial year. The process falls under the goods category and addresses the need within the utilities special regime, with the possibility of contract renewal aligning with regulatory cycles if no other market suppliers emerge.

This procurement offers a significant opportunity for businesses involved in the development and supply of sensor technology, especially those capable of innovating or enhancing products to meet similar requirements in niche markets like wastewater management. Companies operating at the intersection of electronic manufacturing and environmental technology that can provide alternative or improved sensor solutions stand to gain in competitive advantage. Furthermore, businesses experienced in servicing utility markets may find opportunity in offering maintenance and continued support services for the extended lifecycle of the contract, including spares and consumables over the ensuing years. The reliance on a single supplier underscores the potential market gap for alternatives, inviting businesses to engage in research and development to compete in future tenders.

Notice Title

Wastewater Nitrous Oxide in Liquid Sensors and Controllers

Notice Description

This Contract award notice is linked to PPN Notice identifier: 2025/S 000-028704 linked here: https://www.find-tender.service.gov.uk/Notice/028704-2025?origin=Dashboard#top UU are looking to source sensor equipment capable of detecting & measuring Nitrous Oxide in liquid. The requirement of detection in liquid is fundamental to this product; sensors for gas state do not meet this requirement. UU are looking for 120 sensors for immediate requirement, along with appropriate fitments, controllers, pipe mounting equipment, cabling and calibration kits. The initial requirement should also include consumables to run the sensors for 12 months. Our research shows probe heads have a usable lifespan of 6 months. There will likely be on ongoing requirement for spares and consumables for 5 years. Our market intelligence leads us to the conclusion there is only 1 suitable product on the market currently, from Unisense, shown here: https://unisense-environment.com/products/n2o-wastewater-sensor/ We are expecting the cost to come in at approximately PS1M based on the product set from Unisense over 12 months. With a consumables requirement of a further PS1M over the following 4 years. This notice is designed to test our sourcing intelligence with the market for competing product availability.
