UK Competition Network (UKCN)

Documents issued by the members of the UKCN – the CMA and the individual sector regulators – about how competition law will be applied in the regulated sectors.

The UK Competition Network (UKCN) is an alliance of the Competition and Markets Authority (CMA) with all the UK regulators that have a specific role to support and enable competition within their sectors.

The Enterprise and Regulatory Reform Act 2013 includes a range of measures to strengthen the regime for the concurrent application of competition law in the regulated sectors.

The Competition Act 1998 (Concurrency) Regulations 2014 sets out certain rules and procedures for enhanced co-operation between the CMA and sector regulators in the application of competition law in the regulated sectors.
