As part of our performance reporting we account for the impact of our work, in two ways:
An independently validated statement of the financial savings achieved as a result of a direct link between the NAO's work and a quantifiable beneficial change in an audited body. These savings totalled £1.15 billion in 2014.
Case studies of non-financial and/or less directly attributable financial benefits.
The savings statement and some of the case studies are included in our Annual Report and Accounts.
The case studies can also be searched on the publications page of our website.
