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.

The counts under this question show how many awards have a known supplier size.

Last 36 months.

Buyer: 24 of 196 known-size awards · market: CPV 0912 · UK-wide, n=47
12%2%

Small firms have won here. Neither number says whether you qualify; it describes who has been winning.

How often do local suppliers win?
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 the winner is registered in the region where that contract was delivered.

A local branch does not count if the registered address is elsewhere.

Last 36 months.

Buyer: 61 of 170 known-location awards · market: CPV 0912 · UK-wide, n=49
36%31%

Most of this buyer’s recorded winners are registered outside North West England.

How long to a decision?
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.

Last 36 months.

Buyer: no decision dates published · market: CPV 0912 · UK-wide, n=22
—10 days

Half of these awards were announced within 10 days of the bid deadline.

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.

Both shares are minimums: some awards have no bid count.

Thin markets produce this too; it is not proof of a tailored specification.

Last 36 months.

Buyer: at least 247 of 284 procurements with awards had no recorded rival · market: CPV 0912 · UK-wide, n=59
87%22%

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

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.

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.

    And also provide answers to the questions below:

    Sellafield would like to understand the potential for supplying low carbon gas to the site to support its targets in 2030 and beyond. The following questions are being asked:

    1. Please provide your name, contact details, and email address so that we can keep you advised of any changes in the proposed procurement schedule.
    2. Supply volume – Can the nominal demand be supplied wholly or in part with a low carbon gas?
    3. Availability - When that may be available?
    4. Pricing - What is the short- and long-term pricing structure (assume a 10-year requirement)?
    5. Location - What options exist for local or arm’s length gas production? – i.e. will facilities that supply gas be co-located and Sellafield the only off taker or is production elsewhere?
    6. Incentives - What support is available to enable transition away from purely natural gas? Either via incentive schemes or by other means
    7. Continuity of supply - How will the integrity of supply be considered? The Fellside plant runs continuously, and it is expected that this supply is maintained in a similar manner to the current gas supply. If additional inspections or activities are required either as a precursor to accepting gas or as part of additional maintenance, then this should be identified. This also includes any changes through blends.
    8. Carbon savings – Sellafield would like to understand the carbon savings in TeCO2e expected by switching to this product.
    9. Are asset modifications necessary? How might the current system need to be modified to accept a low carbon supply. It is not expected that a detailed engineering assessment is required. An indication on applicability or what types of adjustments might be needed e.g. burners, pumps, pipework etc.
