Multi-Supplier Framework

A multi-supplier framework admits several competing suppliers and preserves competitive tension throughout the framework period. It is the predominant framework model in European public procurement because it gives buyers access to a panel of qualified suppliers, maintains price discipline through ongoing competition, and reduces dependency on any single provider.

What is a Multi-Supplier Framework?

Under Article 33 of Directive 2014/24/EU, a framework agreement may be concluded with several economic operators, with the number being sufficient to ensure genuine competition, generally interpreted as a minimum of three suppliers where the market allows. The initial competition evaluates all applicants against selection and award criteria, and those who meet the standard are admitted to the framework.

Once established, individual call-off contracts are placed using one of two mechanisms. The first is direct award: where all the terms of the contract are fixed in the framework, the authority places work with the highest-ranked supplier, or uses a cascade mechanism to approach suppliers in descending rank order. The second is mini-competition: where not all terms are fixed, the authority re-opens competition among framework members for each call-off, inviting them to submit refined offers.

Many frameworks combine both mechanisms, using direct award for routine, well-defined call-offs and mini-competition for complex or high-value requirements.

Why it matters for bidders

A place on a multi-supplier framework is valuable but not guaranteed revenue. Unlike a single-supplier framework, admission is the beginning, not the end, of the competitive process. Suppliers on a multi-supplier framework must continue to compete for call-offs, either by maintaining their ranked position or by performing well in repeated mini-competitions.

The strategic question for suppliers is whether the cost of framework membership (bid costs, ongoing participation in mini-competitions, sometimes annual accreditation updates) is justified by the volume and quality of call-offs that flow from it. High-traffic frameworks operated by large central purchasing bodies can generate significant revenue; niche or infrequently used frameworks may not.

Example

A central government department establishes a four-year multi-supplier framework for management consulting services, admitting eight firms across two lots. Lot 1 covers strategy and policy; Lot 2 covers digital transformation. For requirements under £50,000, the department places direct award call-offs with the Lot 1 firm ranked first. For requirements over £50,000, it runs a mini-competition among all Lot 1 firms, issuing a brief and scoring responses on quality and price.

Frequently Asked Questions

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

The directives do not set a precise maximum, but Article 33 of Directive 2014/24/EU requires that a multi-supplier framework has at least three members where the market allows. In practice, frameworks range from three to over a hundred suppliers, depending on market depth, lot structure, and the buyer's appetite for managing a large panel.

Can new suppliers join a multi-supplier framework once it is established?

Generally no, under EU Directive 2014/24/EU rules. The framework is closed to new entrants after award. This is one distinction from a Dynamic Purchasing System (DPS), which remains open to new applicants throughout its life. The UK Procurement Act 2023 introduced the Dynamic Market as a more open alternative.

What happens if a supplier on the framework cannot deliver a call-off?

The buyer typically moves to the next-ranked supplier (the cascade) or re-runs the mini-competition excluding the non-performing firm. Persistent failure to respond to or deliver call-offs may result in removal from the framework, depending on the terms established at framework award.
