This Order brings into force, on the day after it is made, the remaining regulation-making powers in Schedule 6 to the Welfare Reform Act 2012 (c. 5). The Schedule enables the Secretary of State to make provision by regulations for the purpose of, or in connection with, replacing existing benefits (see section 33 of that Act, which specifies the “existing benefits” that are to be replaced) with universal credit.
