These Regulations make amendments to Schedule 4 to the Enterprise and Regulatory Reform Act 2013 (c. 24). Part 3 of Schedule 4 contains provisions dealing with the constitution of and procedure for groups of independent panel members of the Competition and Markets Authority (“the CMA”) carrying out certain functions of the CMA, including functions in respect of appeals and references from decisions of utility regulators. The amendments made to Schedule 4 by these Regulations are consequential on changes to the system for modifications to gas and electricity licences in Northern Ireland made by the Gas and Electricity Licence Modification and Appeals Regulations (Northern Ireland) 2015 (S.R. (N.I.) 2015 No. 1) (“the NI Regulations”).
