Procurement Act 2023: What UK Suppliers Need to Know

Practical summary of the Procurement Act 2023 for UK suppliers. Covers key changes, new rules for tenders, SME provisions, and what to expect from buyers under the new framework.

The Procurement Act 2023 came into force in October 2024, replacing the previous EU derived procurement regulations that had governed UK public sector purchasing for decades. For suppliers bidding on government, NHS, local authority, and other public sector contracts, this is the most significant change to procurement law in a generation.

This guide explains what the Act means for you as a supplier and what practical changes to expect.

What Has Changed

A Single, Simplified Regime

The old framework included multiple sets of regulations covering different types of procurement (public contracts, utilities, concessions, defence). The Procurement Act consolidates these into a single regime covering all public procurement above threshold values. For suppliers, this means less complexity and more consistency in how different buyers run their processes.

New Procurement Procedures

The Act replaces the old procedures (open, restricted, competitive dialogue, etc.) with a more flexible set of options. The key procedures under the new Act are the open procedure (single stage, all suppliers can bid), the competitive flexible procedure (allowing buyers to design multi stage processes suited to the procurement), and the direct award procedure (for specific circumstances where competition is not required).

The competitive flexible procedure is the most significant change. It gives buyers far more freedom to design procurement processes that suit their needs, which means suppliers may encounter more variety in how tenders are structured.

Transparency Requirements

The Act introduces significantly enhanced transparency obligations. Buyers must now publish more information at every stage of the procurement process, including pipeline notices (planned procurements), tender notices, award notices with details of the winning bid, contract modification notices, and contract performance information.

For suppliers, this increased transparency has practical benefits. Pipeline notices mean you can identify opportunities earlier and plan your bid pipeline. Published performance data helps you assess competitors and identify buyers whose requirements match your strengths.

The Central Digital Platform

All procurement notices must be published on a new central digital platform, replacing Find a Tender. This platform is designed to be the single source of truth for public procurement opportunities in the UK. Suppliers should register on this platform and set up alerts relevant to their sectors and capabilities.

What It Means for SMEs

The Act includes several provisions specifically designed to improve access for small and medium sized enterprises.

Simpler Assessments

Buyers are encouraged to streamline qualification assessments and avoid disproportionate requirements that disadvantage smaller businesses. Financial turnover requirements, for example, should not automatically exclude SMEs from competing for contracts they can deliver.

Direct Access

The Act encourages buyers to break contracts into lots where practical, making it easier for smaller suppliers to compete for portions of larger requirements.

Prompt Payment

Payment provisions in the Act reinforce the requirement for 30 day payment terms throughout the supply chain, including subcontractors.

Exclusion Grounds

The Act updates and simplifies the exclusion grounds that suppliers must declare. Mandatory exclusions cover serious offences such as fraud, corruption, modern slavery, and tax evasion. Discretionary exclusions cover issues such as poor past performance, professional misconduct, and insolvency.

Suppliers should review the updated exclusion grounds and ensure their self declarations are accurate and current.

Practical Changes for Tender Responses

Evaluation Criteria

The Act requires buyers to be clearer about their evaluation criteria from the outset. Assessment criteria must be published in the tender notice, and buyers must explain how they will assess each element of the submission.

For suppliers, this means the information you need to structure your response should be more clearly signalled in the tender documents. Use this to your advantage by aligning your response structure precisely to the published criteria.

Standstill Period

The standstill period (the gap between award decision and contract signature) remains in place. Unsuccessful suppliers continue to have the right to receive feedback and challenge decisions during this period.

Dynamic Markets

The Act introduces "dynamic markets" as a replacement for Dynamic Purchasing Systems (DPS). These are open frameworks that suppliers can join at any time, rather than only at the initial setup stage. If you operate in sectors where DPS arrangements are common, look for dynamic market opportunities as they offer ongoing entry points.

What Stays the Same

Despite the changes, the fundamentals of writing strong tender responses remain the same. You still need to answer the question directly, provide specific evidence, tailor your response to the buyer, demonstrate value, and submit on time.

The evaluation principle of most economically advantageous tender (now called "most advantageous tender") continues to be the basis for award decisions. Quality and price remain the core assessment dimensions.

How to Prepare

Review your standing documentation to ensure it aligns with the updated exclusion grounds and standard selection criteria. Register on the new central digital platform and set up alerts. Update your case study library to ensure evidence is recent and relevant. Familiarise yourself with the new procedural terminology so you recognise opportunities when they appear.
