C294/2025/2026 Baglan Contamination Remediation Works
Authority: Llywodraeth Cymru / Welsh Government (Central government)
What is being bought
Published requirement descriptionThe Baglan Bay site, in the South Wales area was previously operated as a chemical works and was acquired in 2022. The aspiration for the development of the site is to transform the area through the creation of high-quality jobs, creating a safe and higher quality environment for local people, and to contribute to the wider redevelopment of the region. However, due to previous usage of the site, remediation will be required to safely bring the site back into the wider public sphere.
The Welsh Government is providing potential market participants with early notice of the forthcoming Baglan Contamination Remediation Procurement. This notices, and supporting document provides preliminary details in respect of the background, objectives and intended delivery approach for the Project , to enable interested organisations to consider and prepare for the formal tender process, which is expected to commence in Q3/Q4 2026. The information contained is provided for the purpose of awareness only. It does not constitute a call for competition, nor does it commit the Welsh Government to proceed with any procurement. The Welsh Government intends to launch the Project procurement through the Competitive Flexible Procedure under the Procurement Act 2023. The Contractor will be responsible for design, testing, implementation of remediation techniques, monitoring and validation.
To ensure fairness to the market, Welsh Government will offer two opportunities to share information with companies about the remediation works. There will be an optional Site Visit and an optional Online presentation for companies to attend. Welsh Government is committed to sharing all essential information with all bidders and will keep written records of who participated, what was discussed, information that was shared and how risks of distortion were mitigated. This is to ensure no unfair advantage is gained through participating in the market engagement.

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. The market figure counts awards delivered in Wales (Cymru).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners were registered in the region where that award was delivered.
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 43 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.
Both shares are minimums: 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.

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.
