One-In, One-Out (OIOO) Methodology, July 2011. Overview of OIOO:

• The objectives of the OIOO policy are to: bear down on the cost and volume of regulation in the economy; and encourage departments to implement regulation only as a last resort, having first considered the use of non-regulatory alternatives.
• The key headlines for the OIOO Rule are that: the initial scope of OIOO includes any new UK legislation which imposes a direct annual net cost on business or civil society organisations (IN); for any direct net cost imposed on business and civil society organisations, departments must identify and remove existing regulations with an equivalent value (OUT); departments will be asked to identify compensatory OUTs at the same time that INs are cleared by the Reducing Regulation sub-Committee (RRC). Measures for which OUTs have not been identified will normally be delayed; and departments are expected to put in place plans leading to the commencement of OUTs as soon as possible.”
