Competition for Collected and purified water (CPV 41), and who usually turns up

THAMES WATER UTILITIES LIMITED has too little published record in this market to describe on its own. Published market evidence for the same work stands beside whatever it has. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Collected and purified water (CPV 41) →

How the contest usually goes

Winner shares use published awards; bid and price charts use contested lots.

Question for the bidWhat to do with it
How often do SMEs win?
i

How often small and medium firms win.

Share of awards where the winner’s size is known.

—

Nothing published for this market either.

How long to a decision?
i

How long buyers here take to decide after bids close.

How often single-bid or direct?
i

How often work is awarded with no recorded rival.

Direct awards and tenders where every published lot count shows one bid.

Assess each lot
i

What past awards tell you about each lot.

See the forecast, this buyer’s earlier suppliers and firms with relevant wins.

No supplier is confirmed as a bidder.

Open a lot for its forecast, this buyer’s previous supplier and possible competitors, from published award history, not a bid list

Lot #160 monthsEstimate not published
Expected competition
i

How many bids this lot may attract.

The forecast uses similar past competitions. The bar shows either that forecast or past bid counts; the line below says which.

Each lot shows its own forecast based on its own category; forecasts for different lots of the same notice are not comparative.

A forecast, not a list of bidders.

—No model forecast yet
No comparable market history for this lot’s category yet; the expected-bid figure comes from the model alone or is withheld.
Commercial price forecast
i

Where the award price may land.

The forecast uses similar awards and the buyer’s estimate. The band covers the middle half of likely prices.

No comparable awards for this lot yet.

A statistical guide from past awards, not a price to bid.

—Estimate not published
The buyer published no estimate for this lot, so there is nothing to forecast against. A price prediction here would be a number about a number we do not have.

Who has supplied this buyer on similar work?
i

Who has done similar work for this buyer.

Past contracts are matched by buyer, title and type of work.

A past supplier may not bid again.

No earlier contract of this buyer matches this lot on the published record.

Who could compete for this lot?
i

Who could compete for this lot?

Firms with relevant past wins. On a framework, we show firms on that agreement.

None is confirmed as a bidder.

Candidate suppliers for this notice have not been worked out yet, so this is not a verdict that nobody fits.

About this data
  • Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
  • Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
  • Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
  • Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.

    The Procurement Act 2023 does not apply to water supply options. Thames Water Utilities Ltd is keen however to ensure maximum publicity for its requirements and that the process is open to competition. Thames Water Utilities Ltd does not undertake by this notice or otherwise that it will comply with the Procurement Act 2023 in relation to water supply options.

    Any suppliers who wish to respond to this notice must request an initial Preliminary Screening Survey (PSQ1) by using the contact details available at www.thameswater.co.uk/about-us/suppliers/p… ↗. You will need to indicate whether you are proposing a water supply or demand management/leakage services solution.

    Thames Water Utilities Ltd retains the right not to review any unrequested material. Failure of a bidder to provide the required information, make a satisfactory response to any question, or supply notice referred to in its response to this survey or any clarification within the specified timescale may mean that the bidder will not be invited to participate further in this process.

    Third parties may contact Thames Water at the above address at any time to register their interest, however the proposal may at Thames Water's discretion be considered for inclusion within the WRMP34 process rather than the WRMP29 process, depending on the point in the process at which the proposal is received. Proposals which are clearly beneficial, robust and which are smaller in terms of volume of water delivered (Ml/d) are more likely to be considered for inclusion in our programme sooner in the planning process.

    At the qualification stage, registered applicants who are proposing water resources solutions may either qualify individually or as part of a consortium/joint venture with other registered applicants. This notice does not preclude Thames Water Utilities Ltd or its associated companies (subsidiaries, sister, parent companies, etc.) from issuing other procurements within the scope of supply or services covered by this notice from time to time.

    Unless specifically stated otherwise, Thames Water Utilities Ltd shall not be responsible for any costs, charges or expenses incurred by applicants and does not accept liability for any costs, charges or expenses incurred by applicants, irrespective of the outcome of any process, or if any process is cancelled or postponed. Thames Water Utilities Ltd reserves the right to terminate any process (or part of it) at any time. Thames Water Utilities Ltd reserves the right to procure any of the services or supplies referred to in this notice separately.

    Note that your client may be Thames Water Utilities Ltd or another company within the Kemble Water group structure.
