What it takes to win
i

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).

Evaluation split and conditions of participation as published; the tender pack may add more
How bids were scored · same split on all 10 lots
Quality: 60%Price: 40%
Published award criteria (2)
  • Quality: 60
  • Price: 40
What this means for your bid
  • Price carries 40 of 100 points: a 10% discount moves about 4 points. The method statement decides this lot, not the discount.
  • “*Decarbonisation & Investment Works Framework” is a framework: the contest is a place on its panel, up to 100 suppliers, not a single contract.

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