For years, many small business owners assumed public sector contracts were not for them — too complicated, too dominated by large companies, too much paperwork. The Procurement Act 2023 was designed, in part, to change that. Fully commenced in February 2025, it replaced a patchwork of older regulations with a single, modernised framework. This guide explains what actually changed and what your business should do about it.
This article is general guidance based on publicly available information. Procurement rules are detailed and can change, so always check the latest guidance on GOV.UK or seek professional advice for your specific situation.
What Was Wrong with the Old System?
Before the Act came into force, public procurement in the UK was governed by regulations derived largely from EU law. These rules were fragmented and, many argued, tilted the playing field towards large established suppliers who had the resources to navigate lengthy and complex tender processes. Smaller businesses often found the upfront compliance burden — lengthy pre-qualification questionnaires, demands for three years of audited accounts, insurance requirements set far higher than the contract value warranted — simply not worth the effort.
The Act replaced the main regulations governing central government and most public bodies in England, Wales, and Northern Ireland. Scotland has its own procurement legislation, though the principles are broadly similar.
Key Changes Under the Act
The reforms introduced several changes that matter most to smaller suppliers:
A Single Central Digital Platform
The government launched a central digital platform — Find a Tender and its successor systems — where public bodies are required to publish contract notices, award notices, and other procurement information. The goal is transparency: businesses should be able to find opportunities in one place rather than hunting across dozens of different portals. Buyers are also required to publish more information about their pipelines, so suppliers can see what contracts are coming up in advance and prepare.
Simpler Pre-Qualification
The Act introduced a standard set of exclusion grounds and a shorter, more proportionate approach to pre-qualification. Buyers are no longer supposed to demand information that is irrelevant to the contract, and there are expectations around setting financial requirements at a level that is actually proportionate to the contract value. This should — in theory — reduce the barrier for smaller businesses that were previously screened out for reasons unrelated to their ability to do the work.
A New Duty to Have Regard to SME Participation
Contracting authorities now have an explicit duty to consider how their procurement approach might support small and medium-sized business participation. This does not mean quotas or guaranteed contracts, but it does mean buyers are expected to think about whether the way they structure a procurement unnecessarily excludes smaller suppliers.
More Transparent Award Decisions
When a contract is awarded, the Act requires contracting authorities to publish more information about why they chose the winning supplier. Unsuccessful bidders are also entitled to a debrief. This matters for small businesses because it gives you meaningful feedback to improve future bids — not just a form letter saying you were unsuccessful.
Transparency is the thread running through the entire Act. When buyers have to explain their decisions publicly, it creates accountability that benefits all suppliers — but especially smaller ones who previously had little visibility into how decisions were made.
What Has Not Changed
It is worth being realistic. The Act creates better conditions for SME participation, but it does not automatically level the playing field. Large, experienced suppliers still have advantages: established relationships, dedicated bid teams, and a track record that speaks for itself. Winning public sector contracts still requires effort, preparation, and a clear understanding of what buyers are looking for. The rules are fairer, but the work is still yours to do.
It is also worth noting that some types of procurement — particularly lower-value contracts and some specialist areas — work differently, and not every public body is covered in exactly the same way. Check GOV.UK for the specifics that apply to the types of contracts you are interested in.
What Should SMEs Do to Be Ready?
If you want to take advantage of the improved landscape the Act creates, here is where to focus your effort:
- Register on the central digital platform. Make sure your business profile is complete and up to date. Buyers can search for suppliers, and a well-maintained profile helps you be found.
- Watch the pipeline. The increased transparency requirements mean more forward planning information is available. Use it to identify contracts coming up in your sector months in advance, so you are not scrambling when an opportunity goes live.
- Prepare your standard documents. Even with simplified pre-qualification, you will still need things like your company accounts, insurance certificates, and policies on areas like equality and environmental responsibility. Having these ready in an organised folder saves time when deadlines are tight.
- Always ask for a debrief. Whether you win or lose, request a debrief. The feedback is genuinely useful and will help you improve.
- Start small. If you are new to public sector bidding, look for lower-value contracts in your area or sector to build your track record before going after larger opportunities.
