In 2005 Government undertook an exercise to measure, for the first time in the UK, the administrative burdens of regulations on businesses and the third sector. The administrative burden as of May 2005 was £13.4 billion. More information can be found at:

Information on the total costs of regulations (not just administrative burdens) to UK industry is not currently held centrally and there is no established methodology for measuring these on a consistent basis.
