Contracting Authority

A public-sector body legally required to follow procurement regulations when buying goods, works or services. Includes central government departments, local authorities, NHS bodies, and utilities operating under public control.

Definition

A contracting authority is any body governed by public law that is obliged to comply with the UK's public procurement legislation when awarding contracts above relevant thresholds. The term is defined in the Procurement Act 2023 (which largely replaces the Public Contracts Regulations 2015 for most authorities) and encompasses a wide range of public bodies beyond central government alone.

Who Qualifies

The following bodies are typically classed as contracting authorities:

• Central government departments and executive agencies (e.g. HMRC, DVLA)
• Local authorities (district, borough, county and unitary councils)
• NHS trusts, integrated care boards and foundation trusts
• Higher and further education institutions funded substantially by public money
• Housing associations and registered social landlords in certain circumstances
• Other bodies governed by public law — broadly, organisations established to meet needs in the general interest, not having an industrial or commercial character, and either financed or supervised by the state

Utilities (water, energy, transport, postal services) may fall under separate utilities-specific rules.

Why the Classification Matters

If a body is a contracting authority, it must:

1. Advertise contracts above threshold values on Find a Tender (FTS) or the forthcoming central digital platform under the Procurement Act 2023 2. Run compliant tender procedures (open, restricted, competitive flexible, etc.) 3. Apply the statutory exclusion grounds and selection criteria rules 4. Publish award notices and, under the 2023 Act, produce pipeline notices and contract performance reports

Failure to comply can result in procurement challenge, contract ineffectiveness, or financial penalties.

Boundaries and Grey Areas

Determining whether a body is a contracting authority is not always straightforward. The three-limb test — general interest purpose, non-commercial character, and public financing or oversight — must all be considered together. Case law (including European Court rulings still relevant to UK interpretation) has shaped how these criteria apply to arms-length bodies, special purpose vehicles, and mixed public-private entities.

Procurement Act 2023 Context

The Procurement Act 2023 (expected to come into force in February 2025) retains the concept of contracting authority but introduces a unified framework covering most public contracts, replacing the fragmented regime of PCR 2015, UCR 2016, and CCR 2016 for the majority of in-scope bodies.
