Procedure

Features
Yorkshire Water will run a multi-stage procurement using the competitive flexible procedure in accordance with the Procurement Act 2023. Stage 1 - Conditions of Participation (CoP): Interested suppliers submit a COP Questionnaire. Responses are assessed against defined pass/fail Selection Criteria to determine whether suppliers meet Yorkshire Water's minimum requirements. Yorkshire Water may conduct one or more rounds of Selection and reserves the right to shortlist suppliers progressing to subsequent stages. Stage 2 - Contractual Compliance: Shortlisted suppliers will be invited to review and, where permitted, comment on the Proposed Contract. Yorkshire Water will refine and finalise the contract terms during this stage. Only suppliers who accept the final contract terms will progress to the ITT stage. Stage 3 - Invitation to Tender (Quality & Commercial): Suppliers will submit detailed quality and commercial tenders, which will be evaluated in accordance with the award criteria set out in the ITT documentation. Following evaluation, Yorkshire Water will identify the most economically advantageous tenders and award places on the Technical Services and Assurance Framework. The procedure structure and indicative timelines are set out in the procurement documents.

Description
The framework will operate on a multi-supplier basis, with Yorkshire Water awarding call-off contracts in accordance with the procedures set out in the Framework Agreement. Prices for call-offs will be determined using the pricing schedules established at tender, with the ability to confirm or adjust pricing where permitted by the call-off process. Call-off contracts may be awarded either directly, where the framework provides an objective method to identify the most suitable supplier for a defined requirement, or following a further competition among the suppliers appointed to the framework. Yorkshire Water will apply the framework rules consistently to ensure transparency, fairness and proportionality in allocating work, while enabling flexibility to meet programme needs. The operation of the framework will be governed by the terms of the Framework Agreement and the procedures communicated during the procurement process.
