Important information

This page is a partial view. It's built from tender opportunities and award notices published by buyers on public tendering portals, and shouldn't be relied on as a complete record of this organisation's tendering activity.

  • Work won through panel arrangements, direct sourcing, or any process the buyer chose not to publish won't appear here - so this organisation's actual activity may be larger than what's shown.
  • Award amounts are as published by the buyer at the time of award. Contracts are often varied afterwards and those variations aren't always published, so the final value may differ.
  • Metrics - win rate, top category, category mix, activity recency, buyer diversity and the monthly tendering-activity summary - are all derived from this same published bid and award history.
  • Win rate counts only bids with a confirmed outcome: awarded to this supplier, or to a competitor. Bids with no published outcome are shown separately as pending, never counted as a loss. We only report a rate once a supplier has at least 5 confirmed outcomes — below that a single bid would read as 0% or 100%, which says nothing about a track record.
  • We take care compiling this information but can't guarantee it's complete or current. If something looks wrong, let us know.
  • If you represent this organisation, and wish to enhance this page with further details such as a business overview, contact phone number, email address and website URL, you can do so via our contact form.
