In July the government published Procurement Policy Note 04/19, which sets out how payment approaches can be taken into account in the procurement of major government contracts. The note applies to all central government departments, their executive agencies and non departmental public bodies, which must apply this Procurement Policy on all procurements above £5m per annum, advertised on or after 1 September 2019.

The accompanying guidance explains how to include an assessment of a supplier’s payment systems to demonstrate it has a reliable supply chain and when it would be appropriate to exclude those suppliers that cannot demonstrate they have effective systems in place. It also gives examples of exceptional circumstances where it might not be relevant or proportionate to apply the Note.
