Question to the Cabinet Office:

To ask Her Majesty's Government what guidance they provide to public authorities to ensure that suppliers who pursue late payment claims against them are not disadvantaged in future public procurement exercises with those authorities.

Guidance for central government departments, including their Executive Agencies and Non Departmental Public Bodies on prompt payment policy is available in Procurement Policy Note – Prompt Payment Policy and Reporting of Performance:

https://www.gov.uk/government/publications/procurement-policy-note-0515-prompt-payment-and-performance-reporting

If a supplier feels that they are being disadvantaged in a procurement exercise having made a late payment claim against the contracting authority, contrary to relevant laws, they should raise this issue with the government’s Mystery Shopper service.
