In 2005, Sir Denis was commissioned by the Home Secretary to review the fitness of the current police force structure, which resulted in the publication of the report ‘Closing the Gap’ suggesting options for change. Other reviews undertaken during his tenure include ‘Intercepting Terrorism,’ a review published in October 2006 on police capabilities for counter terrorism, and ‘Getting Organised,’ a report published in October 2008 on serious and organised crime.

His team provided support to the Olympics Programme in testing the Olympic assurance process. In the Inspectorate he introduced Value for Money profiles for all police forces in England and Wales in 2008/9 to assist comparisons to achieve greater efficiency and effectiveness during austerity. This has been followed by a series of studies to track police availability (2010) and the preparedness of police forces and authorities for the austerity spending period (2011,2012); police relationships with the media and other parties (2011).
