What is being bought

Published requirement description

The ISIS Neutron and Muon Source Facility, part of UKRI’s Science and Technology Facilities Council, are looking to procure a replacement three-phase Alternating Current (AC) Magnet Power Supply System to make up the losses in a resonant magnet circuit.

The requirement is for a modular 1200 kVA three-phase AC voltage source power supply that includes a control system capable of regulating the designated magnet load current to a given setpoint and to a high level of stability. It is important to emphasise that the magnet load current to be regulated is not the same as the AC power supply output current and the measurement signal for the load current will be provided by the facility in the form of a DCCT with a -10/+10 V signal representative of the load circuit current. The three-phase output shall have a variable voltage output from 0 V to 250 V line-neutral and an output voltage accuracy of ±50 mV. The system shall be fed from a nominal 400 Vrms AC, 3-phase 50 Hz sinusoidal supply, intrinsically safe by design, with high efficiency, high reliability, high maintainability and fully compliant and marked with relevant standards.

What it takes to win

How this buyer will score bids.

The evaluation criteria and weights exactly as published on the notice, grouped by family (price, quality, social value and so on).

No conditions of participation were published on the notice; check the tender documents.

What this means for your bid
  • Price carries 30 of 100 points: a 10% discount moves about 3 points. The method statement decides this lot, not the discount.
  • Turnover usually expected at this size: about £3,110,796 (twice the annual value).

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula. Turnover is an indicative market norm (≈2× annual value), not a published condition.

Winner shares use published awards; bid and price charts use contested lots.

Question for the bid
This buyerUK Research and Innovation · division 31
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: 53 of 125 known-size awards · market: CPV 3168 · South East England, n=6
42%33%

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 registered in South East England.

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

Last 36 months.

Buyer: 17 of 32 known-location awards · market: CPV 3168 · South East England, n=6
53%17%

Most of this buyer’s recorded winners are registered in South East 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: 5 decided notices · market: CPV 3168 · UK-wide, n=12
19 days24 days

Half of these awards were announced within 19 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 94 of 185 procurements with awards had no recorded rival · market: CPV 3168 · South East England, n=7
51%71%

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?

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.
