Code Governance Review

Many of the technical and commercial rules and obligations that govern participation in Great Britain’s gas and electricity sector are set out in a series of multilateral codes and agreements.

Typically, network operators are obliged under their licences to put these codes in place.  Each code is designed to be capable of modification with the network operators, the signatories to the code and, in some cases, Consumer Focus and other interested parties about to raise modifications. The rules governing how these proposals must be assessed vary from code to code.

Both individually and collectively, the codes significantly impact on the shape and development of the gas and electricity sectors and, by extension on our ability to deliver competitive markets that best protect the consumer interest.

Our Code Governance Review project sought to improve the governance arrangements of these codes and reduce fragmentation. The first phase of this review implemented changes primarily to the gas Uniform Network Code, the Electricity Balancing and Settlement Code and the Connection Use of System Code. The second phase sought to extend the Code Governance Review outcomes to other industry codes and agreements.
