About commercial


We are experts on the government’s commercial work, regulation and contract management.

Commercial and regulatory arrangements are central to policies and programmes right across central and local government.

The public sector now buys in more than it spends itself on delivering services, buys increasingly complex things in increasingly complex ways, and regulates large areas of private sector spending.

Our audits have shown government: 

  • how it can improve its commercial and regulatory capability;
  • the value of managing its contracts well; and
  • how to regulate effectively, through reporting on individual programmes and regulatory interventions.

The reports, frameworks and guidance on this page contain advice and tools to support commercial work, regulation and contract management.
