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

Lots publish different evaluation splits; there is no single procedure weighting.

Lot	Quality	Price	Social value	Split
1 · Cleaning, chlorination, sampling and analysis of hot and cold-water services, including instantaneous water heaters	35%	60%	5%
2 · The bacteriological sampling of swimming pools	35%	60%	5%

What this means for your bid

Price carries 60 points on every lot: a 10% discount moves about 6 points.

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