Each government department has published detailed information about projects on the Government Major Projects Portfolio (GMPP). This includes a Delivery Confidence Assessment rating, financial information (whole life cost, annual budget and forecast spend), project schedule and project narrative.

The data reflects the status of the GMPP at 30 September 2015 and is published in support of the 2016 Infrastructure and Projects Authority (IPA) annual report.

A department may exempt data from publication under exceptional circumstances, in accordance with Freedom of Information requirements.

ONS Census Transformation Programme: appointment letter for Senior Responsible Owner (SRO)

The guidance for officials giving evidence to Parliamentary Select Committees, known as the Osmotherly Rules was updated on 17 October 2014. As part of this update government is committed to publishing lists of the SROs for projects on the Government Major Projects Portfolio (GMPP).

To address this commitment the Infrastructure and Projects Authority (IPA) publishes lists of the SROs responsible for government major projects. This data was previously published by the Major Projects Authority, which merged with Infrastructure UK on 1 January 2016 to form the IPA.

This aims to improve transparency and accountability for the government’s major projects.

A full list of SRO appointment letters can be found here.
