Single-Supplier Framework

A single-supplier framework concentrates the contracting authority's future spend in a defined category with one pre-selected and evaluated supplier. Because the competitive element is exhausted at the framework award stage, call-offs during the framework period are placed directly without further tendering. This structure suits requirements that are well-defined, stable in scope, and where one supplier can reliably meet all anticipated demand.

What is a Single-Supplier Framework?

Under Article 33 of Directive 2014/24/EU, a framework agreement may be concluded with a single economic operator. The contracting authority runs a full competitive procedure to select that operator, setting out the pricing, service standards, and terms that will govern call-offs. Once the framework is awarded, the authority may issue direct award call-offs at any point during the framework period without re-opening competition.

The principal advantage for buyers is simplicity: they know exactly who will deliver, at pre-agreed prices, and without the administrative overhead of repeated mini-competitions. For the winning supplier, a single-supplier framework provides a high degree of revenue visibility and can justify investment in dedicated resources or infrastructure for the buyer's benefit.

Single-supplier frameworks are common in categories such as specialist legal services, bespoke software maintenance, facilities management for a defined estate, and utility supply contracts. They are less appropriate where requirements are diverse or unpredictable, where market prices are volatile, or where a single supplier cannot realistically meet all anticipated demand.

Why it matters for bidders

Winning a single-supplier framework secures all of the buyer's spend in that category for the framework period (up to four years under EU rules). This is a powerful commercial outcome. The competitive pressure is entirely front-loaded: a supplier who loses the framework competition is excluded from all call-offs until the next framework is established.

For incumbents, the renewal competition is therefore a high-stakes event. Buyers cannot simply roll over a single-supplier framework without a new competition: each framework requires a fresh tender process. Suppliers who have held a framework should prepare for the re-competition well in advance, since a new entrant can displace them entirely.

Example

A regional government runs a competitive tender for a four-year single-supplier framework for translation services. One supplier is awarded the framework at agreed per-word rates across seventeen language pairs. Over the following four years, each departmental translation request is placed directly with that supplier under a simple call-off order, with no further competitive process required for individual assignments.

Frequently Asked Questions

Can the contracting authority use other suppliers during the framework period?

In principle, no. If a requirement falls within the scope of the framework, the authority should use the framework. However, if a requirement falls clearly outside the framework's scope or lot structure, a separate procurement may be justified. The boundary between in-scope and out-of-scope requirements is a common source of challenge.

What happens if the single supplier cannot deliver?

This is a recognised risk of single-supplier arrangements. Contracts typically include step-in rights, key person provisions, business continuity requirements, and termination-for-cause clauses. If the supplier fails materially, the authority may need to run an emergency procurement or access an alternative framework agreement held by a central purchasing body.

Is a single-supplier framework the same as a sole source award?

No. A single-supplier framework is competed openly; the buyer runs a full tender, and any eligible supplier can apply. A sole source (or direct award outside a framework) bypasses competition entirely and is only lawful in narrow circumstances defined by the directives. The competitive foundation of a single-supplier framework is what makes call-offs legally defensible.
