An contracting authority is the public sector body or organization responsible for setting up, managing, and awarding contracts under a framework agreement.

This means the contracting authority is the body that:

• Designs and publishes the tender – setting out what goods, works, or services are needed.

• Evaluates supplier bids – assessing which organisations can meet the requirements.

• Selects and appoints suppliers – awarding them a place on the framework.

• Managing the framework – ensuring it runs effectively and in line with procurement rules.

Once a framework is established, the awarding authority (and sometimes other approved organisations, known as participating authorities) can call off or issue contracts to the suppliers listed.

For charities looking to supply services—whether in health, social care, community development, or training—it’s important to know who the contracting authority is, because:

• They control access to opportunities under the framework.

• They provide the rules and requirements you’ll need to meet.

• They act as the main point of contact during procurement.

By understanding the role of the awarding authority, charities can engage more effectively, prepare stronger bids, and build lasting relationships with the public sector.

For example the Charities Buying Group (CBG) establishes a framework for essential supplies and services tailored to the needs of the voluntary sector. In this case, the Charities Buying Group is the contracting authority.

Suppliers  that are awarded a place on that framework can then be approached directly through the CBG to provide goods or services. This arrangement helps streamline procurement, reduce costs, and ensure that charities are working with trusted, pre-approved suppliers.
