The changes to regulations affecting business during the 2010-15 Parliament are recorded in Statements of New Regulation that were published every six months. These are available on https://www.gov.uk/government/collections/one-in-two-out-statement-of-new-regulation.
For the 2015-17 Parliament, the Government will shortly publish its final report on the savings to business delivered during that Parliament.
For the current Parliament, the Government is committed to maintaining a proportionate approach to regulation to enable business growth while maintaining public protections. This will be monitored through the target that the Government is required to set under the Small Business, Enterprise and Employment Act 2015.
