Important amendments to procurement legislation

Important amendments to procurement legislation

On 24 February 2025 the Procurement Act 2023 (PA 2023) came into force.

This is significant for both public sector entities and their suppliers because the PA 2023 replaces the well-established EU-founded regime under the Public Contracts Regulations 2015 which previously governed public sector procurement processes.

The most striking change to the law is that the PA 2023 introduces a new supplier exclusion and debarment regime which means that suppliers who fail to meet particular standards or pose particular risks (for example, risks to national security) can be debarred from tendering for public contracts. This goes further than the previous regime which only allowed for suppliers to be excluded from particular projects.

In addition to the obvious financial implications of being precluded from participating in new tenders or being awarded call-off contracts, there are likely to be reputational consequences for the affected suppliers as debarred suppliers will be added to a public register, with the ground for their debarment also given.

There are routes to challenge disbarment but, just like any other public procurement challenge, it is advisable to take action quickly and obtain specialist advice to avoid falling foul of the procedural hurdles and limitation issues which claims of this nature often face.
