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.
  • “UKRI-4731 - Supply of Cryogenic Methane Moderator Systems” is a framework: the contest is a place on its panel, up to 6 suppliers, not a single contract: call-offs may be direct or by further competition.

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
