How the Procurement Act 2023 Opens Public-Sector Work to SMEs (and How to Be Ready)

Public-sector construction work has a reputation among SMEs for being the preserve of the big players — too much bureaucracy, frameworks locked up by tier-one contractors, and bid requirements that only a large business can satisfy. The Procurement Act 2023, which went live in February 2025, was written partly to change that. For smaller AEC firms willing to get their house in order, it represents a real opening.

What actually changed

The Act consolidates a tangle of previous regulations into a single regime and shifts the emphasis in ways that favour smaller, capable suppliers. Three changes matter most for SMEs. First, there is a stronger duty on contracting authorities to consider the barriers SMEs face and to design procurements that do not exclude them by default. Second, larger requirements are more likely to be broken into lots, so a smaller firm can bid for a slice rather than the whole. Third, transparency has increased across the pipeline, so upcoming opportunities are more visible earlier — giving organised bidders time to prepare rather than scramble.

Alongside this sits a central digital platform for registering and finding opportunities, and a greater weight on past performance — which cuts both ways. A strong delivery record becomes a genuine asset; a patchy one becomes visible.

Why this is an opportunity for smaller firms

Breaking contracts into lots is the single biggest lever. A £20m programme that once went to one main contractor may now be split into packages that a specialist or regional SME can credibly deliver. Combine that with earlier visibility of the pipeline and a level-playing-field duty, and the practical barrier shifts from “are we big enough?” to “can we demonstrate we are capable and organised?” That is a question SMEs can win on — if they prepare. Much of this builds on themes we covered in how SMEs can win more public-sector work with BIM compliance.

How to be ready

Winning public work under the new regime is less about grand gestures and more about being demonstrably in control of your delivery. The firms that convert opportunities have a few things in place before the tender even appears:

• Register on the central platform and monitor the pipeline. Set yourself up to see opportunities early rather than reacting to a live tender with two weeks left.
• Build an evidence library. Case studies, quality certifications, health-and-safety records, and financial information, kept current, so a bid is an assembly job rather than a panic.
• Demonstrate delivery governance. Authorities increasingly want to see how you will run the work, not just that you can. A credible project execution plan and clear information management are exactly the kind of evidence that scores well.
• Get your BIM and information credentials in order. Public projects lean on ISO 19650, and being able to show genuine capability sets you apart from firms that claim it on the cover sheet only.
• Protect your performance record. With past performance carrying more weight, delivering your current jobs well is itself a bid strategy.

The bottom line

The Procurement Act will not hand SMEs public work — but it has quietly removed several of the reasons they were shut out. The winners will be the smaller firms that treat readiness as an ongoing discipline: registered, organised, evidenced, and delivering visibly well. If public-sector work has felt out of reach, this is the moment to build the foundations that put it within it.
