A UK13 notice, formally a ‘Dynamic Market Intention Notice’ under section 39(2) of the Procurement Act 2023, is a required publication a contracting authority must make before it establishes a Dynamic Market. Per Cabinet Office guidance, this is a mandatory legal step, not a discretionary one – a contracting authority cannot set up a Dynamic Market without first publishing a UK13.
A Dynamic Market itself isn’t a one-off contract competition – it’s a standing list of qualified suppliers that one or more contracting authorities can draw on repeatedly, running procurements under it over time. Because setting up (or modifying) a Dynamic Market isn’t a ‘public contract’ in the Act’s terms, the usual contract-award notices don’t apply to it – dynamic market notices, starting with the UK13, are the specific mechanism the Act uses instead.
Regulation 25(2) sets out what a UK13 must contain, and the guidance is clear that it should give suppliers enough detail to decide whether to apply.
UK13 notices are published whenever a contracting authority is preparing to set up a new Dynamic Market, and can appear at any point in the procurement calendar.
A UK13 is the one point in a Dynamic Market’s life where the conditions for membership are set out in full – and, importantly, those conditions cannot be changed once the market is running, so it’s worth reading closely first time.
Dynamic Markets were introduced under the Procurement Act 2023 to replace dynamic purchasing systems and qualification systems with a single, more flexible commercial tool, and UK13 notices exist to make the start of that process transparent.
A UK13 notice is a mandatory step a contracting authority must take before it can establish a Dynamic Market, and it’s your only real preview of the conditions for membership – which, once set, stay fixed for the life of the market. Suppliers who read it closely and prepare early put themselves in the strongest position when the UK14 Establishment Notice confirms the market is live.
