Modification Without New Procedure

Public procurement law is built on the premise that competition allocates contracts efficiently and fairly. Allowing a contracting authority to change a contract freely after award would undermine that premise, turning the original competition into a misleading exercise. Article 72 of Directive 2014/24/EU therefore creates a closed list of circumstances in which modifications can be made without reopening the market. Understanding those circumstances is essential for both buyers managing live contracts and suppliers assessing incumbent risk.

What is a modification without new procedure?

A modification without new procedure is precisely what it sounds like: a change to an existing contract's terms, scope, price, or duration that is implemented directly with the current contractor, without publishing a new contract notice and inviting fresh competition. Article 72 of Directive 2014/24/EU (mirrored in Articles 89 and 43 of Directives 2014/25/EU and 2014/23/EU respectively) sets out five grounds on which this is lawful.

The first ground is that the modification was provided for in clear, precise, and unambiguous review clauses or options in the original contract documents. The second is that additional works, services or supplies are needed that could not be foreseen, the contractor must remain the same for economic or technical reasons, and the value increase does not exceed the modification threshold of 50% of the original contract value. The third is unforeseen circumstances where the authority could not have anticipated the need for change and the value increase remains within the 50% threshold. The fourth is a change of contractor under specific permitted conditions. The fifth is a de minimis modification where the value is below both EU thresholds and 10% of the original value (15% for works).

None of these grounds is a general permission to amend freely. Each has specific conditions, and modifying outside these grounds renders the modification an unlawful direct award.

In the UK, the Procurement Act 2023 codifies comparable permissions while adding its own procedural layer, including the requirement to publish a modification notice in Find a Tender for certain modifications.

Why it matters for bidders

When a contracting authority modifies a contract without new procedure, competing suppliers lose the opportunity to bid for the additional scope or the revised contract. This is why understanding the legality of such modifications matters to the market. If you believe a competitor's contract has been unlawfully extended or expanded without competition, you may have standing to challenge the modification before a national review body.

Conversely, if you are the incumbent, understanding these grounds allows you to advise your client on how to structure proposed changes lawfully, reducing the risk that a practical amendment creates a serious legal dispute.

Example

A Spanish regional government holds a transport services contract. Mid-term, heavy rainfall damages several road sections, requiring emergency route adjustments and additional vehicle deployments not contemplated in the original scope. The authority invokes the unforeseen circumstances ground under Article 72(1)(c), adjusts the contract, and publishes a modification notice publication in TED because the additional value exceeds the relevant threshold. The modification is lawful because the original authority could not reasonably have anticipated the weather event, the contractor must remain the same for operational continuity, and the 50% cap is respected.

Frequently Asked Questions

Is there a numerical limit on modifications without new procedure?

For the additional works and unforeseen circumstances grounds, the cumulative value of all modifications under those two grounds cannot exceed 50% of the original contract value. For de minimis modifications, the limit is below both EU threshold values and below 10% (or 15% for works) of the original contract value.

Can a contracting authority use modification without new procedure repeatedly?

Yes, subject to the cumulative caps. However, a series of modifications specifically designed to circumvent the procurement rules is explicitly prohibited under Article 72(4). Courts will look at the overall pattern, not just each individual change.

What is the difference between modification without new procedure and a direct award?

A direct award is the original contract being given to a supplier without competition. Modification without new procedure applies to a contract that was properly competed and awarded. The legal test for modification without new procedure is therefore about whether the change is so substantial that it effectively creates a new contract requiring its own competition.
