Question for the bid
This buyerSOUTH WESTERN RAILWAY LIMITED · all categories
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: 3 of 17 known-size awards · market: CPV 3460 · UK-wide, n=30
18%10%

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.

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.

Last 36 months.

Buyer: 12 of 18 known-location awards · market: CPV 3460 · UK-wide, n=33
67%39%

Most of this buyer’s recorded winners were registered in the region where that award was delivered.

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: division 34 · UK-wide, n=171
—45 days

Half of these awards have an award date within 45 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.

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.

Last 36 months.

Buyer: exactly 20 of 22 procurements with awards had no recorded rival · market: CPV 3460 · UK-wide, n=44
91%64%

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?

How many bids past lots received.

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.

    Feedback is requested in relation to this market engagement. Your feedback is important as it will allow views from the market to inform the development and finalisation of the procurement strategy which will in turn help define the tender.

    SWRL would greatly appreciate your feedback in the form of a response to the questionnaire in SWR004513.

    Please submit your responses via SWRL's e-procurement portal Wax-digital swrl.medius-s2c.com/S2C/DisplayModules/T… ↗ All responses will be treated confidentially.

    Following analysis, a high level summary report will be issued to participants, giving an overview of the general themes and findings; no participant will be mentioned by name in the report.

    Completion of the questionnaire does not constitute an expression of interest in any future tender. Responses will not be used to evaluate your company, create a short-list or guarantee inclusion or exclusion in any resulting tender exercise.

    All responses will be carefully considered but will not bind SWRL to any particular approach to the procurement, nor will responses be treated as conveying any promise or commitment on the part of the respondent. SWRL is not liable for any costs incurred.

    For your feedback to be taken into account, your completed MEQ must be received by 13 March 2026, no later than 14:00pm. Any questions on the content of the questionnaire should also be submitted via SWRL's e-procurement portal correspondence.

    We recommend that you refer to the e-tendering guidance for suppliers . All communication should be via SWRL's e-procurement portal Correspondence function on the project.

    SWRL wishes to explore the market to understand the availability and interest of potential suppliers who can manufacture and deliver a range of Train Spare Parts, Accessorises and Consumables to its designated depots across the south west region in England for use in its various asset maintenance areas (Rolling stock, Track, and Signals etc). A small sample of the requirement have been listed as information to accompany this questionnaire as examples of the type of products and requirements involved.

    SWRL is considering whether our requirements could be met by one supplier or whether multi-suppliers are better suited.

    SWRL engineering team works in a reactive environment; although some requirements(including larger scale project requirement ) can be forecast in advance, products/parts demands also originate from emergency situations. Due to necessity such requirement will require agile suppliers both in terms of capacity(increased requirement during a short notice and or period of time) and the time (emergency response when required).
