How many suppliers share its contracts

21 distinct suppliers won at least one contract from this organisation. The five most frequent account for 27.3%.

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.

how it's calculated — The five most frequent suppliers

The five most frequent suppliers — where the number comes from

The calculation
6 awards to the five most frequent suppliers ÷ 22 awards = 27.3%
What goes in
22 winning awards on this contracting authority's notices, excluding cancelled or unsuccessful awards, shared among 21 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.

On the horizon

What the published sources let you see coming at this buyer — each row with its source and its date; none of them announces a call for tenders.

Contracts ending

None of this buyer's contracts ends in the next 12 months. 20 of the 20 contracts have a published end date.

Purchases that come back

No category yet has at least four distinct processes and three observed cycles in the reliable historical period.

Codes that only name a broad segment (ending in 000000) are set aside: they do not describe the same purchase.
