How this service works
Public-procurement record of a UK company from Find a Tender (above-threshold notices since 2021) and Contracts Finder (below-threshold since 2023), Cabinet Office OCDS feeds under OGL v3: contracts WON matched by company number — buyer, subject, contract value in GBP, award and signature dates, period, status, official notice link — and notices ISSUED as a buyer, newest first, with totals. Only half of suppliers carry a company number: zero is a non-conclusive absence. Facts, never a score.
Output
A structured JSON response containing: (1) contracts WON — list of awards matched by company number including buyer name, contract subject, value in GBP, award date, signature date, performance period, status, and link to the official notice; (2) notices ISSUED as a buyer, ordered newest first; (3) aggregate totals for both categories. Only contracts where the supplier carries a company number are matched; zero results does not conclusively mean no contracts exist.
Example use cases
Supplier due diligence before onboarding
“We're about to onboard a new supplier — company number 07452163. Can you check their UK public procurement history to see what government contracts they've won and roughly how much they've earned from the public sector?”
Competitive intelligence on a rival bidder
“I need to understand our competitor's government contract track record. Their UK company number is 04158954 — find out which public contracts they've won, the contract values, and who the buyers were.”
Auditing a public body's procurement notices
“Company 00756473 acts as a public buyer — can you pull all the tender notices they've issued so I can review what they've been procuring and whether any contracts are still active?”
Technical details
Endpoint
GEThttps://api.sirenic.eu/v1/eu/entreprise/GB/:company_number/marches-publics?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need factual, official UK public procurement data for a specific company identified by its Companies House number. It is the right choice for supplier due diligence, competitive intelligence on government contract wins, auditing a public body's issued notices, or enriching a KYB workflow with procurement history. Prefer it over general web search when you need structured, machine-readable OCDS data with verifiable source links. Note the coverage limitation: above-threshold notices from 2021 and below-threshold from 2023 only, and roughly half of supplier records carry a company number.
Side effects
- 404 returned when company number is unknown or not found — payment is cancelled
- Company has contracts but no company number recorded on the notice (approximately half of suppliers lack one), leading to zero results that do not confirm absence
- Company number must be exactly 8 characters with leading zeros; malformed input may yield no results
- Data coverage starts from 2021 (Find a Tender, above-threshold) and 2023 (Contracts Finder, below-threshold) — older contracts will not appear
- Rate-limited or payment failure scenarios typical of x402 micropayment endpoints
