Procedure

Features
Suppliers will be invited to submit for PSQ, following which then are evaluated to confirm eligibility and shortlist bidders progressing to the ITN stage. The ITN is then issued, followed by a clarification window so all bidders have consistent information before preparing submissions. Once ITN responses are received, Thames Water completes a full evaluation covering commercial, technical and legal aspects, and then down-selects to a smaller group for negotiation. Negotiation and final clarification follow, giving suppliers the opportunity to improve and optimise their proposals where appropriate "this maybe more than 1 round". The process concludes with internal approvals, contract finalisation and award. This approach is designed to be clear and proportionate for bidders, while allowing iterative engagement where it genuinely adds value and ensuring a transparent, value-focused selection process.

Lot structure will be retained for governance and call-off eligibility, while enabling Thames Water to procure integrated requirements where needed (particularly under Lot 4).
