Aggregated Procurement

Aggregated procurement is a strategic approach to public purchasing that recognises that buying power increases with volume. By consolidating demand, public bodies can negotiate better prices, reduce the overhead of running multiple separate competitions, and standardise the goods and services they procure. EU procurement law actively facilitates aggregation through framework agreements, dynamic purchasing systems, and centralised purchasing bodies, while also setting rules to prevent aggregation from being used to exclude SMEs.

What is Aggregated Procurement?

Aggregated procurement takes several forms in EU procurement law and practice.

Demand aggregation by a single authority: a contracting authority combines all its requirements for a category of goods or services into a single procurement rather than making multiple separate purchases. This ensures the full value is correctly estimated for threshold purposes and allows the authority to negotiate more effectively. Article 5 of Directive 2014/24/EU establishes the rules for estimating contract values, including the requirement to aggregate related requirements.

Framework agreements: Article 33 of Directive 2014/24/EU allows one or more contracting authorities to establish a framework agreement by running a single competitive process, then awarding individual call-off contracts under the framework over its duration (maximum four years). The initial framework competition delivers the aggregation benefit; subsequent call-offs can be awarded rapidly without a new full process.

Dynamic purchasing systems (DPS): Article 34 allows an entirely electronic purchasing system for commonly used goods, works, and services, which remains open to new economic operators throughout its duration. A DPS is particularly useful for categories where market supply changes frequently.

Centralised purchasing: a centralised purchasing body runs procurements on behalf of a large number of contracting authorities, achieving scale that individual authorities could not reach.

Aggregated procurement must be distinguished from the prohibited practice of artificial splitting, which is breaking up what should be a single contract into smaller pieces to avoid the threshold. The obligation to aggregate correctly means that related requirements must be valued together, not separated to stay below detection.

Why it matters for bidders

Aggregated procurement creates both opportunities and challenges for suppliers. The opportunity is access to large consolidated contracts or frameworks that provide sustained revenue across multiple contracting authorities. The challenge is that aggregation can produce contracts so large that SMEs cannot realistically bid for the prime contract.

EU procurement law addresses this tension directly. Article 46 of Directive 2014/24/EU encourages (though does not mandate) the division of large contracts into lots to facilitate SME participation. Contracting authorities that decide not to divide into lots must explain their reasoning. Where lots are used, suppliers can bid for individual lots that match their capacity, even if they cannot bid for the entire aggregated requirement.

Example

A consortium of twenty Irish local authorities operates through a shared purchasing office and uses a framework agreement for office supplies established by running a single EU-wide open procedure. Individual authorities issue call-off orders against the framework throughout the four-year term without running separate competitions. The aggregation achieves significant unit cost savings relative to each authority procuring independently, and the framework is accessible to suppliers of all sizes through appropriately sized lots.

Frequently Asked Questions

Is there a maximum size for a framework agreement in EU procurement law?

Directive 2014/24/EU does not set a maximum monetary value for framework agreements, but it does limit their duration to four years (with exceptions for the utilities and defence sectors where longer frameworks may be justified by the nature of the market). The value of a framework is estimated as the maximum total value of all call-off contracts expected to be placed during its term. This estimated maximum must be published and determines whether the EU threshold is exceeded.

Can aggregation disadvantage SMEs?

Yes, and this is a recognised risk that EU procurement policy addresses. Very large aggregated contracts create barriers to entry for smaller suppliers that lack the capacity to bid at the required scale or to absorb the financial risk of a large single contract. The mitigations available within the framework of Directive 2014/24/EU include lot division, proportionate financial standing requirements, and the ability for SMEs to bid as part of a consortium. Contracting authorities are encouraged to consider SME access when designing aggregated procurements.

Must an authority always aggregate its requirements, or can it keep purchases separate?

Authorities must not artificially split requirements to avoid thresholds, but they are not required to aggregate every purchase that falls into the same category. Operational reasons may justify separate procurements: different timing, different locations, different specifications. The key is that the decision to procure separately must be based on genuine operational grounds, not on a desire to stay below the threshold that would otherwise require a more competitive process.
