Understanding the Debarment Regime Under the Procurement Act 2023

16th June 2025

The UK Procurement Act 2023 introduces a pivotal change for suppliers through the implementation of a centralised debarment regime. For businesses that regularly compete for public contracts, understanding this regime is essential to maintain eligibility and avoid permanent exclusion.

In this blog, we’ll break down what the debarment regime means, how it impacts suppliers, the exclusion criteria, and how Tender Consultants can help you stay compliant and competitive.

What is the Debarment Regime?

The debarment regime is a new mechanism introduced under the Procurement Act 2023, enabling the UK government to maintain a central debarment list of suppliers deemed unsuitable to bid for public contracts. This list will be publicly accessible and regularly updated by the Debarment Authority, a new regulatory function designed to enforce supplier standards.

This approach replaces the fragmented exclusion practices across different contracting authorities and brings a consistent and transparent process to public procurement.

Why Has the Debarment Regime Been Introduced?

The central aim of the new regime is to improve the integrity, fairness, and transparency of the UK’s public procurement system. By identifying and excluding suppliers who have demonstrated serious or persistent misconduct, the government aims to:

  • Protect taxpayer money
  • Promote responsible business conduct
  • Level the playing field for ethical suppliers

Criteria for Supplier Exclusion

The Procurement Act 2023 outlines both mandatory and discretionary exclusion grounds. Suppliers can be added to the debarment list based on the following criteria:

Mandatory Exclusion

  • Convictions for offences such as corruption, bribery, or terrorism
  • Fraud affecting the financial interests of the government
  • Modern slavery or human trafficking violations

Discretionary Exclusion

  • Breach of environmental, social or labour laws
  • Grave professional misconduct
  • Persistent poor performance on past contracts
  • Serious misrepresentation in procurement procedures

Contracting authorities are required to exclude suppliers listed under mandatory grounds and may choose to exclude those under discretionary grounds.

Implications for Businesses

Being placed on the debarment list can have serious and long-lasting consequences:

  • Loss of eligibility to bid for any public contracts in the UK
  • Reputational damage impacting private-sector partnerships
  • Increased scrutiny in future applications

Even if you’re not currently bidding for contracts, being on the debarment list could affect your ability to enter the public procurement space in the future.

How to Stay Compliant and Avoid Debarment

Avoiding debarment means maintaining high standards across your operations. Here are some practical steps to take:

1. Robust Compliance Framework

Ensure your business complies with all relevant legal, environmental, and labour regulations. Implement regular audits and reviews.

2. Transparent Record Keeping

Maintain clear records of your business’s ethical practices, financial conduct, and contract performance.

3. Staff Training

Educate your teams on procurement risks and the importance of adhering to public sector standards.

4. Prompt Issue Resolution

Act quickly to rectify any contract performance issues and maintain open communication with clients.
