How to read the radar
- End date is the contract period end the buyer published on the notice. Contracts without an end date are not on the radar; neither are contracts the buyer cancelled or terminated early.
- Extension option means the notice publishes a renewal or option clause; the buyer may extend. Hiding these rows shows contracts without a published option, but does not establish that the buyer will procure them again.
- Incumbent is the supplier named on the award behind the contract. A panel (several suppliers on one award) is shown as a panel; no single incumbent is invented.
- Annual run-rate = published GBP value ÷ published term for a single supplier and a term of six months or more. Vehicle-linked values have no run-rate until their commercial role is verified. The annual sort ranks comparable values excluding VAT first; gross-only values remain visible on their rows. This is not actual annual spend.
- Counts are exact for the time-horizon and sector filters. A parent framework or DPS counts once; call-offs published by other buyers count separately. Where the parent cannot be identified, agreements stay separate and are marked as vehicle-linked; check the source notice before treating their date or value as a single contract fact. With other filters, a result above 1,000 units shows as “1,000+”.
- Source. Official UK procurement notices, reused under the Open Government Licence v3.0; the radar is rebuilt nightly. How we count: methodology.
