Published requirement description

IMPORTANT: Please read this section before deciding whether you wish to register for this event. This section provides you with information regarding the scope of this procurement and details some of the key requirements that a successful applicant MUST be able to deliver.

Thames Water intends to establish a single-lot, sole-supplier framework agreement for the provision of pump optimisation and aeration efficiency services across Thames Water operational assets.

The scope of the framework includes monitoring, testing, and analysis of pumping and aeration systems and associated equipment. The objective is to identify and deliver opportunities to reduce whole-life costs, improve efficiency, and optimise performance across operational sites.

The contract will include:

- Fixed pricing structures with agreed review mechanisms.

- Key performance indicators (KPIs) and performance monitoring requirements to ensure delivery against expected outcomes.

- Requirements to support collaborative working and a transition from transactional delivery to strategic partnership.

Suppliers will be expected to support a culture of continuous improvement and contribute to ongoing enhancement of processes and delivery approaches throughout the contract lifecycle.

Delivery Model

The anticipated delivery model will follow a structured approach comprising:

- Initial site identification and data collection.

- Project mobilisation and stakeholder engagement.

- Efficiency and control studies to identify optimisation opportunities.

- Approval to proceed to testing and monitoring.

- Site-based testing and performance monitoring activities.

- Review of outcomes, including business case validation.

- Handover for delivery through relevant engineering or capital delivery mechanisms.

The contract is expected to support a programme of approximately 200 tests across 60 operational sites during the AMP period.

Further detail on the scope, service requirements, and call-off mechanisms will be provided within the procurement and contract documents.

The following conditions would be considered as some of key requirements for a supplier to meet to be considered for this opportunity:

• Must be able to cover the Thames Valley, London and Home Counties geographical area

• Must have a proven track record in delivering measurable savings and innovation within the scope of this framework.

Thames Water reserves the right to refine the award criteria. Please note that that deadline for asking for access to the PSQ & submitting of the PSQ is 19 October 2026, at 12:00pm.

  • The authority expects to re-tender this requirement around 1 May 2034, 23:59 BST.
  • How the procedure runs: Thames Water is seeking to establish a sole-supplier framework agreement for Pump Optimisation and Aeration Efficiency Analysis. The procurement process has been designed as a multi-stage procedure to enable Thames Water to evaluate technical and commercial proposals and engage with bidders. Bidders will submit a Pre-Selection more…Questionnaire (PSQ) via SAP Ariba to assess suitability, capability, and capacity. Bidders who successfully pass the selection stage will be invited to participate in the Invitation to Negotiate (ITN) stage. Bidders will be required to submit initial tenders setting out their proposed technical and commercial solutions. Following initial tenders, Thames Water may conduct clarifications, negotiations, and presentations to support understanding and refinement of proposals. Tenders will be evaluated in accordance with the award criteria set out in the procurement documents. Thames Water will evaluate final tenders and award a sole place on the framework to the supplier submitting the Most Advantageous Tenders based on the published award criteria. All procurement documents, communications, and submissions will be managed via SAP Ariba. Suppliers must register on the system and submit all responses through this platform. Further details of the procurement process, including evaluation methodology, scoring, and detailed requirements, will be provided in the procurement documents issued at each stage.

How this framework works

From the published notice
Type
Closed framework
Call-offs
call-offs are awarded directly to appointed suppliers, without further competition
Framework period
3 yrs · up to 8 yrs from 10 May 2027
Published description of the framework

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.

Method and what to read with care
  • Two columns, no blending. The authority column walks its own record only: notices in the 4-digit class, then the 2-digit division, then all categories (36 months, per lot, contested only), and as a last resort its 24-month row across all categories (per notice, every route). The market column is the notice’s primary delivery ITL1 × the same class, then division (36 months). Nothing is filled from the UK-wide class; an empty tile means the source published nothing usable.
  • Per lot, contested only. Find a Tender publishes bid counts per lot; a seven-lot tender is seven contests. Procedures awarded without competition (limited / direct) are excluded from bids, price pairs and decision days — they report one bid by definition. Frameworks and DPS are a separate population from contracts (6–7 bids per lot against 2–4) and only the notice’s own kind is shown.
  • Coverage. Roughly 40 % of notices publish a bid count; about half publish an ITL1 delivery location, so the market column reads the authority’s registered region when the notice has none (labelled). Award-vs-estimate pairs need a lot estimate, one active award on the lot, one canonical supplier and a gap under 60 %; about 30 % of pairs are exact matches (the buyer published the award at the estimate). n is on every figure; below 3 the tile is muted, never hidden.
  • Pounds. The expected award applies the authority’s median movement (or the region’s, when the authority has fewer than 3 pairs) to this notice’s estimate; the middle half uses the region’s quartiles. A multi-lot notice publishes an envelope, so the movement is applied per lot, never to the total. A benchmark, not a recommended price.
  • “Match” and “relevance” are model scores from the nightly matcher, not published facts. Find a Tender does not publish who is bidding. Never shown: contact details, payment behaviour, or a recommended price.
