Direct award Yorkshire Water conducted a market engagement exercise, for which a Market Engagement Notice 2026/S 000-007262 dated 27 January 2026 was published, to which a number of companies submitted responses. This market engagement exercise was carried out to understand whether there were suppliers capable of delivering renewable private wire electricity to sites across the Yorkshire Water operational estate. The market engagement demonstrated that there were a number of suppliers capable of meeting YWs requirements across its estate but only a single respondent capable of meeting YWs requirements at its Blackburn Meadows waste water treatment works in Sheffield. As a result, a competitive tendering process would not generate genuine competition and a direct award is justified as a feasible route to delivering the required services withing the desired timeframes and to the required quality standards.
