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.

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.

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.

How THAMES WATER UTILITIES LIMITED buys Consultative engineering and construction services (CPV 7131) — and who usually turns up
THAMES WATER UTILITIES LIMITED’s own published record, next to the Greater London market for the same work. This notice is a framework or DPS, so only frameworks and DPS are compared. Whole-market view: sector page →
How the contest usually goes
Left: this authority. Right: the market where the work is delivered. Bids and award-vs-estimate pairs are per lot, from contested frameworks and DPS only — direct awards report one bid by definition and are left out. Empty means nothing was published, not filled in from elsewhere.

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.
