Framework operation description

The framework will be established as a single-lot, sole supplier framework agreement. Call-off contracts will be awarded directly to the appointed supplier, with competition taking place at the framework award stage.

Thames Water intends to establish a collaborative and strategic working relationship with the appointed supplier, with a focus on delivering continuous improvement, innovation, and long-term value across the contract lifecycle.

Pricing for the framework will be based on an agreed schedule of rates (rate card), which will form the basis for pricing all call-off contracts. The detailed structure and coverage of the rate card will be defined and agreed as part of the procurement process.

Prices will be fixed for the initial three (3) year term of the framework agreement. Following this period, prices may be subject to adjustment in line with the Consumer Prices Index including owner occupiers' housing costs (CPIH). Any such adjustments will be subject to agreement between Thames Water and the Supplier and applied in accordance with the terms set out in the contract.

The scope, programme, and pricing of individual call-off contracts will be agreed between Thames Water and the Supplier at the point of award, in line with the agreed rate card and contractual terms.

The framework will include appropriate performance management and commercial governance arrangements, including the use of key performance indicators (KPIs) and regular review mechanisms, to ensure delivery of value for money and support a collaborative, high-performing supplier relationship.

Further detail on the pricing structure, indexation mechanism, and call-off process will be provided in the procurement and contract documents.
