How many suppliers share its contracts

2,690 distinct suppliers won at least one contract from this organisation. The five most frequent account for 7.2%.

Counted by number of contracts, never by amount. This figure aggregates, it does not rank; the table below names the most frequent — published acts, not a league table.

The five most frequent suppliers — where the number comes from

The calculation
528 awards to the five most frequent suppliers ÷ 7,381 awards = 7.2%
What goes in
7,381 winning awards on this contracting authority's notices, excluding cancelled or unsuccessful awards, shared among 2,690 distinct suppliers. An award shared by several suppliers counts once for each. Awards are counted, not amounts, and no supplier is named. Awards with no linked supplier, or whose supplier is hidden, stay out.

Time to decision — where the number comes from

The calculation
For each notice: the calendar days between its closing date and its first award date. The number shown is the median of these delays, rounded to the day: 62 days.
What goes in
547 notices go in: those with a closing date whose earliest dated winning award, neither cancelled nor unsuccessful, falls on or after the closing day. This contracting authority's other notices stay out. This count comes from the delay computation, made at another time than the count of published notices: the two do not subtract.

How to read it
Between the closing date of a public tender and its award, this contracting authority takes 62 days on median — half of its notices are awarded between 43 and 82 days (over 547 notices). Across all contracting authorities the median is 26 days (over 119,539 notices): 2.4 times. A longer wait describes a purchasing practice, not an irregularity. It is computed only on notices carrying both a closing date and an award date.
