- Quality: Quality weighting recorded here is inclusive of the Social Value weightings.
- Technical & professional ability

- Price carries 60 of 100 points: a 10% discount moves about 6 points. This one is won on the number: sharpen the price before polishing the prose.
- “Window Replacement & Associated Works” is a framework: the contest is a place on its panel, up to 10 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.
