What this means for your bid
  • Price carries 70 of 100 points: a 10% discount moves about 7 points. This one is won on the number: sharpen the price before polishing the prose.
  • “Window Replacements 2026/2027 - Low Rise Flats” is a framework: the contest is a place on its panel, not a single contract, and call-offs are awarded directly: getting appointed is the whole game.

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