How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Local means the winner is registered in the region where that award was delivered.
A local branch does not count if the registered address is elsewhere.
The notice lists delivery in Estonia, so this procedure has no confirmed single UK region; the buyer’s figure reads its other awards, each against its own delivery region.
i
How long buyers here take to decide after bids close.
Middle value in days from the bid deadline to the award date, on competitions that published both.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards have an award date within 65 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
The buyer’s share is a minimum: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i

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 Contracting Authority seeks information on Industry’s capability and approaches to removal and disposal of the oil remaining on the wreck of HMS CASSANDRA.
Accordingly, suppliers are invited to respond to this RFI outlining methods for:
- Oil removal from the exposed port side tanks and the accessible starboard tank at the stern.
- In particular addressing how they would deliver such requirement as a two-stage project:
a. Stage 1 (Viability Assessment): Determination of whether the hull of the wreck retains sufficient strength to enable an oil removal (hot-tapping) operation to be safely and successfully undertaken. This stage will conclude with a go/no-go decision on whether to proceed with oil removal based on the assessment of the data collected.
b. Stage 2 (Intervention): Remove the oil, with appropriate environmental safeguards in place, and safely dispose of the oil in accordance with appropriate legislation.
Note: It is envisaged that Stages 1 and 2 will comprise separate deployments to the wreck, potentially separated by a period of several weeks or months. This is to allow a fully informed go/no-go decision based on the results of Stage 1 and, if the decision is made to proceed with the oil removal, time to plan in detail and enact the operation.
Furthermore, suppliers are kindly requested to provide a Rough Order of Magnitude (RoM) cost for performance of the relevant work in line with the methods they have outlined.
Suppliers are requested to email their responses to this RFI to [email protected] by the applicable engagement deadline.
The Contracting Authority has not specified a format for any response as this can limit creativity and make it difficult to understand. Therefore, suppliers are free to present information in their preferred format, provided it is compatible with MS Office. To minimise the need for further clarification, suppliers are encouraged to clearly detail any relevant methodologies, anticipated processes, key assumptions (including applicable environmental safeguards, laws, and regulations), and dependencies, as appropriate.
If suppliers have any questions to inform an RFI response, these can be submitted to [email protected]. To ensure transparency of information, any questions and answers will be published in an anonymised format. Suppliers are therefore encouraged not to include the identity of their organisation within the content of any question. If a supplier believes that a particular question should not be published, they must inform the Contracting Authority of such when asking the question. Publication of the question and response will be at the sole discretion of the Contracting Authority, provided that a supplier may withdraw its question any time prior to receipt of a response.
The Contracting Authority reserves the right to clarify the contents of any RFI response received with the originator. In doing so, the Contracting Authority will act proportionately and seek to minimise the burden on suppliers who have voluntarily responded to this RFI.
This RFI is issued solely for information, market research, and planning purposes. It does not constitute a formal solicitation, Request for Proposal (RFP), or obligation to contract. The Authority shall not be liable for any costs incurred in the preparation of responses.
Any cost information contained in an RFI response and any information furnished by the Contracting Authority in connection with this notice—excluding the notice itself and any public data accessible through hyperlinks embedded within the notice—shall be treated as strictly confidential by the recipient. The recipient shall not disclose such information to any third party without prior written consent of the originator, provided that this shall in no way limit the ability of the Contracting Authority to disclose such information to its officers, employees, agents or advisers or other UK government departments or the Estonian government.
By submitting a response, each respondent grants the Contracting Authority a non-exclusive, royalty-free, perpetual, and worldwide licence to use, reproduce, and distribute the submitted information for evaluation, feasibility assessment, and the drafting of subsequent procurement documents and to enable third parties to use, reproduce, and distribute the submitted information on behalf of the Contracting Authority for the same purposes. Provided that any cost information shall be subject always to the foregoing confidentiality obligation.
For the avoidance of doubt, responses to this RFI will be used by or on behalf of the Authority solely for the purposes of preliminary market engagement, as defined in Regulation 16 of the Procurement Act 2023.
