UK14 Notices Explained: What Suppliers Need to Know About Dynamic Market Establishment Notices

What is a Dynamic Market Establishment Notice?

A UK14 notice, formally a ‘Dynamic Market Establishment Notice’ under section 39(3) of the Procurement Act 2023, must be published as soon as reasonably practicable after a contracting authority has formally set up a Dynamic Market. Where the UK13 signalled intent, the UK14 confirms the market now exists.

Regulation 25(4) sets out what it must contain, and the content is narrower than the intention notice – it’s a factual confirmation of establishment, not a restatement of scope or conditions.

UK14 notices must include:

• The date the Dynamic Market was established
• Details of the suppliers who have been admitted to the Dynamic Market
• Where the Dynamic Market has been divided into parts, which part each supplier has been admitted to

When are Dynamic Market Establishment Notices Published?

UK14s follow on directly from the establishment of a specific Dynamic Market.

• As soon as reasonably practicable after establishment: The Act requires prompt publication once the authority has formally set the market up.
• Not a reopening of applications: The UK14 lists who was admitted as the market was established – it doesn’t set out a new application process, since that was already covered by the UK13.

How can Suppliers use Dynamic Market Establishment Notices?

The UK14 is a useful checkpoint even if you’re not yet a member, since Dynamic Markets are legally required to stay open to new suppliers throughout their life.

• Check who’s already on the market: The list of admitted suppliers gives you a sense of the competitive landscape you’d be joining.
• Don’t assume you’ve missed your chance: Contracting authorities must accept membership applications at any time, consider them within a reasonable period, and admit qualifying suppliers as soon as reasonably practicable – so refer back to the UK13’s application process if you haven’t yet applied.
• Know your rights if a tender is already live: If you apply for membership after a tender notice has been published under the market, the contracting authority must still consider your application before excluding you or disregarding your tender on the basis you’re not a member – unless the procurement is complex enough that there’s genuinely insufficient time.

Why are Dynamic Market Establishment Notices used?

UK14 notices exist to make the formal creation of a Dynamic Market – and its initial membership – a matter of public record.

• Confirms the market is live: Suppliers and other contracting authorities can see exactly when the market came into existence.
• Transparency on membership: Publishing the admitted supplier list (and, where relevant, which part each supplier sits in) lets the market operate as an open, visible register rather than a private list.
• Supports ongoing access: Because membership stays open after establishment, the UK14 is a starting point for suppliers to track – not a closing one.

In Summary

A UK14 notice confirms a Dynamic Market now formally exists and shows who’s on it. It isn’t a fresh invitation to apply – that process was set out in the UK13 – but because Dynamic Markets must stay open to new suppliers at any time, it’s never too late to apply using the route the UK13 described, even after establishment.
