30-second answer

A conflict of interest exists where a personal, financial or organisational connection could influence—or reasonably appear to influence—a procurement decision.

Detailed explanation

Conflicts are not limited to deliberate wrongdoing. They can arise from previous employment, family relationships, financial interests, close professional connections, advisory work, gifts, hospitality or access to information that is not available to other suppliers. The key question is whether the connection could affect impartiality or undermine confidence in the process.

Suppliers should maintain their own conflict controls. Bid teams, directors, consultants, proposed evaluators, subcontractors and advisers may all hold connections that need to be declared. Early disclosure allows the buyer to decide whether the risk can be managed through recusal, information barriers, replacement personnel or another proportionate measure.

A perceived conflict can be as damaging as an actual one. Concealing a relationship because the individual believes it will not influence them may create a more serious integrity issue if the connection is discovered later. Accurate declarations and a clear audit trail protect both the competition and the supplier.

Why it matters

Conflicts must be identified and managed to protect fairness and trust.

How buyers use it

The buyer identifies, records and manages conflicts so that procurement decisions remain fair, defensible and trusted. Measures may include removing an evaluator, restricting access to information, changing responsibilities or obtaining formal declarations.

What suppliers should do

  1. Ask directors, bid staff, advisers and key subcontractors to declare relevant connections.
  2. Review relationships with buyer staff, consultants and incumbent providers.
  3. Disclose potential conflicts through the authorised route promptly.
  4. Record the disclosure, response and agreed mitigation.
  5. Update declarations if circumstances change during the competition.

Frequently asked questions

Does knowing someone at the authority automatically prevent us bidding?

No. The relevance depends on the relationship, the person’s role and whether the risk can be managed. Prompt disclosure is the safest approach.

Should former employees be declared?

Declare the connection where it could reasonably be relevant, particularly if the individual worked on the requirement or retains access to non-public information.

Can a subcontractor create a conflict?

Yes. Conflict checks should cover key delivery partners, advisers and others materially involved in the bid.

What if the conflict appears after submission?

Notify the buyer through the authorised channel as soon as it is identified and explain any proposed mitigation.

Is a perceived conflict important?

Yes. Public confidence and procedural fairness can be affected even where no actual bias is proven.
