This is a list of central purchasing bodies serving public sector procurement in the United Kingdom. Central purchasing bodies are also known as "Public Buying Organisations" (PBOs).^[1] In May 2010 the National Audit Office estimated that there were just under 50 public buying organisations in the UK.^[2]

A "central purchasing body” is defined in the Public Contracts Regulations 2015 as "a contracting authority which provides centralised purchasing activities and which may also provide ancillary purchasing activities". The role of a central purchasing body, as defined in Regulation 37 of the regulations, is to support "the acquisition of supplies or services, or both, intended for contracting authorities", and "the award of public contracts or the conclusion of framework agreements [or dynamic purchasing systems] for works, supplies or services intended for contracting authorities".^[3] The definitions are derived from Articles 2(1)(14) and 37 of the European Union's Directive on Public Procurement, Directive 2014/24/EU,^[4] transposed into UK legislation in 2015. Similar organisations can be found in other EU Member States, for instance Hansel Ltd. in Finland and Consip in Italy.

The EU rules provide that a contracting authority may use the services of a central purchasing body located in another Member State, and should do so in accordance with the national procurement rules which apply where the central purchasing body is located.^[5]

In the UK, central government organisations are required by HM Treasury guidance to use the Government Procurement Service (Crown Commercial Service) in its capacity as a central purchasing body.^[6]

The five consortia collectively operated under the name Pro5,^[18] until WMS ceased to be part of the public sector. "ESPO" is the trading name of a joint committee of these six local authorities established under the Local Government Act 1972 (section 101 (5) and section 102) and section 9EB of the Local Government Act 2000. Initially its purpose was to serve Leicestershire and Lincolnshire as a joint initiative.^[19]

The claimed savings resulting from collaborative use of its frameworks were less than its set-up and running costs.
