The Infrastructure and Projects Authority (IPA) was, between 2016 and April 2025, the United Kingdom government's centre of expertise for infrastructure and major projects. The IPA reported to the Cabinet Office and HM Treasury. The core teams included experts in infrastructure, project delivery and project finance who worked with government departments and industry.
The IPA supported delivery of all types of in frastructure and major projects; ranging from railways, schools, hospitals and housing, to defence, IT and major transformation programmes. The IPA led the project delivery and project finance professions across government through the Government Major Projects Portfolio. It was superseded by the National Infrastructure and Service Transformation Authority (NISTA), established in April 2025.
