It is aimed at suppliers who deliver contracts to the UK public, utilities and defence sectors, who take part in competitive procurements or have delivered contracts under the Public Contracts Regulations 2015, the Utilities Contracts Regulations 2016, the Defence and Security Public Contracts Regulations 2011, and the Concession Contracts Regulations 2016, or new entrants who would like to do so in the future. The guidance also has a section for Small and Medium Sized Enterprises (SMEs) and Voluntary, Community and Social Enterprises (VCSEs).

It is designed to explain the key changes to the previous regulations, and how this may influence how you do business with the UK public, utilities or defence sectors accordingly.
