Conflict of Interest (Procurement)

Conflicts of interest represent one of the most common integrity risks in European public procurement. They can arise at any stage of the process, from needs assessment and specification writing through to contract management, and they undermine the core procurement principles of equal treatment, non-discrimination, and transparency that underpin EU law.

What is a Conflict of Interest (Procurement)?

Article 24 of Directive 2014/24/EU defines a conflict of interest as any situation where staff of the contracting authority or a procurement service provider acting on its behalf who are involved in the conduct of the procedure, or who may influence its outcome, have directly or indirectly a financial, economic, or other personal interest which might be perceived to compromise their impartiality and independence.

In practice, conflicts of interest take several forms. A procurement officer might have a family member employed by one of the tenderers. A consultant helping to draft the technical specification might also be affiliated with a company intending to bid. A committee evaluator might hold shares in a bidding entity. Even where actual impropriety does not occur, the appearance of a conflict can expose the authority to legal challenge.

Contracting authorities are required to take appropriate measures to prevent, identify, and remedy conflicts of interest. The most common control is a declaration of interest form, which all persons involved in a procurement must complete before the process begins. Where a genuine conflict is identified, the affected person must be recused from the procedure.

Under the UK Procurement Act 2023, contracting authorities must have regard to the need to act with integrity throughout the procurement process. The Act reinforces existing requirements to identify and manage conflicts, and extends disclosure obligations to covered procurement relationships.

Why it matters for bidders

As a bidder, a conflict of interest affecting the evaluation team can directly harm your chances of a fair assessment. Understanding this concept matters for two reasons. First, if you suspect that a competing tenderer has an unfair advantage because of a close relationship with the buyer, you have grounds to raise a formal complaint or challenge. Second, you may yourself be asked to declare conflicts: for example, if you advised the contracting authority during market engagement, you may be subject to a prior involvement exclusion under Article 41 of Directive 2014/24/EU.

Prior involvement rules require a contracting authority to take appropriate measures to ensure that competition is not distorted by a candidate who advised it before the procedure. That candidate may participate, but must be given the opportunity to prove their involvement did not distort competition. Buyers and suppliers alike benefit from understanding where these boundaries lie.

Example

A local authority in Belgium is procuring a new IT infrastructure contract. One of the evaluation panel members is the spouse of the managing director of a shortlisted company. The authority's procurement compliance officer reviews the declarations of interest, identifies the connection, and recuses the panel member before evaluation begins. A replacement evaluator is appointed and the process continues. The authority documents the steps taken to manage the conflict in the procurement file.

Frequently Asked Questions

What is the difference between an actual and a perceived conflict of interest?

An actual conflict exists where a person's private interest genuinely influences or is likely to influence their official conduct. A perceived conflict arises where a reasonable, informed observer would conclude that a conflict might exist, even if the person insists their judgment is unaffected. EU procurement rules address both: the standard is not whether bias actually occurred, but whether the circumstances could reasonably give rise to that impression.

Can a supplier who helped write a specification still bid?

Yes, but with conditions. Article 41 of Directive 2014/24/EU allows prior-involvement candidates to participate provided the contracting authority takes measures to ensure competition is not distorted. This normally means sharing with all tenderers the information the prior-involvement candidate had access to, and giving that candidate the opportunity to demonstrate their participation will not distort competition. If distortion cannot be remedied, the candidate may be excluded.

What happens if a conflict of interest is discovered after contract award?

Discovery post-award can lead to contract termination, debarment proceedings, referral to fraud prevention authorities, and in serious cases criminal prosecution. It can also trigger mandatory reporting under the EU Whistleblower Directive (2019/1937) if the disclosing person is a protected reporter.
