Reporting policies and assurance
When referring to ‘this year’ in our text throughout this report we mean the year from 1 April 2008 to 31 March 2009.
This year we appointed Pricewaterhouse Coopers (PwC) as our independent assurance providers. Their assurance report, relating to this report (published on 12 June 2009) can be found as a PDF in the sidebar.
This year we have further defined our principles and methodologies which are detailed in the side bar. Our principles and methodologies for carbon reporting are duplicated in a separate section under Environment.
