Multi-Supplier Contract

A multi-supplier contract (also called a multi-supplier framework or panel) awards approved positions to several suppliers simultaneously, all of whom have passed the selection and evaluation criteria and accepted the framework terms. Individual requirements are then competed among those approved suppliers, either through a mini-competition (where suppliers submit call-off bids) or through a direct allocation mechanism (where the framework rules specify which supplier is called off first, second, and so on based on ranked award at framework level).

What is a Multi-Supplier Contract?

Multi-supplier frameworks are explicitly recognised and regulated under Article 33 of Directive 2014/24/EU. They are used by a wide range of contracting authorities across Europe for requirements where:

• Multiple suppliers have been identified as capable and compliant
• Maintaining competition at the call-off level generates better value than a single-supplier arrangement
• The authority wants resilience and the ability to call off from alternative suppliers if the primary supplier cannot deliver
• The category is diverse enough that different suppliers offer different strengths depending on the specific call-off requirement

When an authority wants to place a call-off under a multi-supplier framework, it must follow the framework's call-off rules, which must themselves be specified in the original framework procurement documents. The two main approaches are:

Ranked direct award. Suppliers are ranked at framework level (1st, 2nd, 3rd). The authority approaches the 1st-ranked supplier first; if they cannot deliver, the authority moves to the 2nd, and so on. No further competition takes place at call-off level.

Mini-competition. All framework suppliers (or a relevant subset) are invited to submit a call-off proposal for the specific requirement. Each call-off is competed on the basis of the evaluation criteria stated in the framework (which may differ from the overall framework award criteria).

For complex or high-value call-offs, mini-competition is usually preferred because it maintains competitive tension. For routine, well-defined requirements (commodity purchases, standard services), ranked direct award may be more efficient.

Multi-supplier frameworks in the UK (including Crown Commercial Service frameworks and NHS Supply Chain contracts) are the dominant mechanism for central government procurement across most categories. In the EU, framework agreements are similarly widespread across member states, central purchasing bodies, and collaborative procurement networks.

Why it matters for bidders

Being admitted to a multi-supplier framework does not guarantee revenue: you must still win individual call-offs. The strategic goal is to secure a framework slot and then invest in winning mini-competitions. This means maintaining responsive bidding capacity, understanding each call-off's specific requirements, and building relationships with the contracting authority's contract management team.

In large multi-supplier frameworks (10, 20, or more approved suppliers), the competition at call-off level can be just as intense as in an open market, particularly for high-value call-offs. Your win rate on mini-competitions is the measure of commercial success on a framework, not your position in the overall rankings.

Example

The UK Crown Commercial Service operates a technology services framework with 30 approved suppliers across multiple lots. When a government department needs to procure an application development team, it runs a mini-competition among the 10 framework suppliers on the relevant lot, evaluating technical proposals and revised prices. The winning supplier is engaged via a call-off contract that sits within the framework terms.

Frequently Asked Questions

How many suppliers should be on a multi-supplier framework?

There is no prescribed minimum or maximum under EU law, but frameworks with too few suppliers (2 or 3) may have limited competitive benefit, while frameworks with too many (30 or more) dilute the commercial return for each supplier and create administrative complexity for the buyer in running mini-competitions. Practice varies widely: commodity frameworks may have many suppliers; specialist professional services frameworks may have 4 to 8.

Can a contracting authority use only one supplier on a multi-supplier framework?

No. If a multi-supplier framework exists and a specific call-off requirement falls within its scope, the authority must follow the framework's call-off rules and cannot award to a supplier outside the framework. Using only one framework supplier for all call-offs without following the mini-competition rules would be a breach of procurement law.

What happens if a supplier on a multi-supplier framework goes into insolvency?

The framework agreement typically includes provisions for removing a supplier from the approved panel if they are no longer able to perform, including insolvency events. The remaining suppliers continue on the framework. The framework may or may not be re-opened to admit replacement suppliers depending on its structure.
