What is being bought

Published requirement description

In accordance with Section 16 of the Procurement Act 2023, the Western Riverside Waste Authority (WRWA) is undertaking Preliminary Market Engagement (PME) to engage with suppliers regarding capacity within the UK waste market to process and treat entire waste streams for which WRWA is responsible.

WRWA's existing Waste Management Services Agreement shall expire in 2032.

To inform the Outline Business Case and Procurement Strategy, WRWA wishes to engage with the market to better understand the interest, capacity and infrastructure the market has in providing the services that WRWA is responsible for.

Participation in this market engagement exercise is not a requirement for participation in the forthcoming procurement, which shall be formally commenced through publication of a procurement notice in accordance with the Procurement Act 2023.

This PMEN is not a call for competition, does not formally commence a procurement process, and is issued solely for the purpose of gathering information and insight from the market.

Objectives of this Preliminary Market Engagement

Through this PME, the Authority seeks to;

Understand market appetite for the Authority's future waste management services

Test potential services delivery models, integrated, disaggregated, lots

Explore capacity, capabilities, innovation and investment appetite, across the Services.

Inform the Authority's infrastructure planning, including potential refurbishment, expansion or use of existing facilities

Identify risks, constraints and opportunities that could influence future commercial and procurement approaches.

Support the development of the Procurement Strategy & Outline Business Case that is transparent, competitive, attractive to the market and deliverable.

This buyerWestern Riverside Waste Authority · this authority
What 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.

How often do local suppliers win?

—41%

Across this market, 41% of winners were registered in the delivery region.

How long to a decision?
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.

Last 36 months.

Buyer: no decision dates published · market: CPV 9050 · Greater London, n=12
—39 days

Half of these awards have an award date within 39 days of the bid deadline.

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.
