Diving services framework 2026 Engagement session
Authority: Natural Resources Wales (Central government)
What is being bought
Published requirement descriptionThis is a supplier engagement session notice in relation to the establishment of Diving services Framework agreement 2026.
Natural Resources Wales (NRW) is seeking qualified professional scuba diving contractors to support our marine biological monitoring programme within Wales' Special Areas of Conservation (SACs).
Working alongside NRW's experienced diving scientists, contractors will help assess the health and condition of key subtidal habitat features - particularly reefs - through in-situ biological surveys. This work is essential for informing statutory reporting on the ecological status of Wales' protected marine sites.
Key Details:
- Location: SACs across Wales, including Pembrokeshire Marine, Pen Llŷn a'r Sarnau, and Menai Strait & Conwy Bay
- Duration: Up to 25-30 days of fieldwork per year, typically between May and September
- Techniques: Species cell-frequency count quadrat surveys, species identification, underwater photography, and video documentation
- Collaboration: Work as part of a joint team with NRW divers and marine ecologists
We're looking for capable, safety-conscious diving professionals with experience in marine ecological surveys and a commitment to high-quality data collection.

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.
Here, local means registered in Wales (Cymru).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered in Wales (Cymru).
i
How long buyers here take to decide after bids close.
Middle value in days from the deadline to the first award notice, on competitions that published both dates.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards were announced 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 market share is a minimum: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Missing bid counts may hide more single-bid awards. This share is a minimum.
How many bids did past lots attract?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.
Past bids do not predict this tender.
1 bid9% / 9%
2–364% / 64%
4–60% / 0%
7+27% / 27%
How did awards compare with estimates?
i
Where winning prices landed against estimates.
Each colour shows awards below, close to or above the published estimate, one lot at a time.
On a framework or DPS, prices are agreed when work is called off.
Past prices are a guide, not a bid price.
Not comparable on a framework or DPS. The notice sets up a supplier panel and a ceiling value; what the work actually costs is agreed later, on each call-off or mini-competition, and those publish as contract notices of their own. The award-vs-estimate record of this market therefore sits on the call-offs; this page shows it on the contracts, not on the panel that frames them.

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.
