Supply of Aluminium Sulphate

Yorkshire Water Services Limited is establishing a framework agreement for the supply and delivery of Aluminium Sulphate to 12 clean sites across the Yorkshire area. The contract has an estimated total value of 28,600,000 GBP excluding VAT. Due to the critical importance of the material, the authority intends to utilize a dual-sourcing strategy. The initial term of performance is estimated from March 1, 2027, to February 28, 2028, with a structured extension process of one-year increments that could potentially extend the agreement through February 28, 2033, based on supplier price and performance. Award decisions will be based on a combined score of commercial factors, weighted at 60 percent, and quality factors, weighted at 40 percent. Tenders must be submitted electronically via the SAP Ariba portal by November 28, 2026. The framework is designed for flexibility, allowing sites to be switched between contracts with nominated suppliers. Administrative inquiries are managed by Jamie Yau and the Professional Service Contracts team at the Ellington House office in Leeds.
