The biggest reform to UK public procurement in a generation is now in force. This paper breaks down what has changed and what it means for small businesses competing for government contracts.
A new era for public procurement
The Procurement Act 2023 came into full effect in February 2025, replacing the Public Contracts Regulations 2015 and the EU-derived procurement framework that had governed UK public purchasing for over a decade. For SMBs, this is the most significant change to the rules of engagement in a generation.
The Act was designed with three broad objectives: to make procurement simpler and more flexible, to increase transparency, and to support a more diverse supply base. On paper, these objectives align closely with what SMBs have been asking for. In practice, understanding the detail is essential for any small business that wants to compete effectively under the new regime.
Key changes that affect SMBs
Simplified procedures
Under the old regulations, buyers had to choose from a fixed set of procedures: open, restricted, competitive dialogue, competitive procedure with negotiation, and innovation partnership. Each had rigid rules about timelines, stages, and documentation. The Procurement Act replaces all of these with two options: the open procedure and the new competitive flexible procedure.
The competitive flexible procedure gives buyers significantly more discretion in designing their procurement. They can set the number of stages, decide how to evaluate, and adapt the process to suit the complexity of the requirement. For SMBs, this means more variety in how tenders are structured. Some may be simpler and faster. Others may involve additional stages such as presentations or demonstrations. The key is to read each tender's process description carefully, because assumptions based on previous experience may not apply.
Transparency and the central platform
The Act introduces a new central digital platform for all public procurement notices. This replaces the patchwork of portals (Contracts Finder, Find a Tender, individual buyer systems) with a single point of access. All contract notices, award decisions, and contract modifications above 5,000 pounds must be published here.
For SMBs, this is a significant improvement. Instead of monitoring multiple portals and risking missed opportunities, there will be one platform to watch. The platform also publishes pipeline notices, giving suppliers advance visibility of upcoming procurements before formal tenders are issued.
Supplier qualification
One of the most persistent complaints from SMBs has been the burden of pre-qualification. Under the old regime, every restricted procedure required a separate selection questionnaire (SQ), often asking for the same information in slightly different formats. The Procurement Act aims to address this by standardising supplier information requirements and reducing the need for repetitive submissions.
The Act also changes how buyers assess suitability. Rather than applying rigid turnover thresholds (which historically excluded smaller firms), buyers are encouraged to take a more proportionate approach to financial assessment. This should, in theory, make it easier for SMBs to pass the pre-qualification stage.
Exclusion and debarment
The Act introduces a new debarment register for suppliers found guilty of serious misconduct. While this primarily targets larger firms with histories of contract failure or fraud, SMBs should be aware of the new mandatory and discretionary exclusion grounds. Maintaining clean governance, health and safety records, and tax compliance is more important than ever.
What has not changed
Despite the reforms, several fundamentals remain the same. Contracts must still be awarded based on published criteria. Buyers must still treat all suppliers fairly and transparently. The requirement for competitive processes above certain thresholds persists, though the thresholds themselves may change over time.
Importantly, the quality of your bid response still matters more than anything else. Legislative reform can open doors, but walking through them requires a well-written, well-evidenced, and well-priced submission.
Practical steps for SMBs
Register on the new central platform. Ensure your company profile is complete, accurate, and up to date. This is now the primary channel through which opportunities will reach you.
Review your standard documentation. The Act changes some of the information buyers can request at qualification stage. Update your standard responses to reflect the new requirements.
Monitor pipeline notices. The new transparency provisions mean you can see what buyers are planning to procure months before the formal tender is issued. Use this time to prepare, build relationships, and position your business.
Invest in bid quality. The competitive flexible procedure means buyers have more freedom to design evaluations that test genuine capability. Presentations, site visits, and demonstrations may become more common. Prepare for a wider range of assessment methods, not just written submissions.
Seek feedback. The Act strengthens suppliers' rights to receive feedback on unsuccessful bids. Use this feedback systematically to improve future submissions. Every debrief is an investment in your next win.
Looking ahead
The Procurement Act 2023 is a framework, not a finished product. Secondary legislation, guidance notes, and buyer practice will continue to evolve. SMBs that stay informed, adapt their processes, and invest in their bidding capability will be best positioned to benefit from a regime that is explicitly designed to make public procurement more accessible to smaller suppliers.
