This Order concerns commencement and transitional provisions in relation with the Water Act 2014. It brings into force provisions which allow the Secretary of State to make regulations that would allow the Water Services Regulation Authority and the Water Industry Commission for Scotland to enable a single application for a water or a sewerage licence in both jurisdictions to be made and the remainder of section 14 of the 2014 Act which amends the special merger provisions in the Water Industry Act 1991. This new special merger regime allows the Competition and Markets Authority (CMA) to determine whether or not to make a merger reference. It also enables the CMA to accept undertakings from the parties to the merger instead of making a merger reference. Transitional provisions concern general authorisation given by the Secretary of State to the Authority under section 17A(1) of the Water Industry Act 1991 and continued application of section 17A(2) to (6) of the 1991 Act to an old water supply licence.
