Background to the industry codes
UK legislation sets out that companies involved in the generation, distribution, transmission, supply or provision through interconnectors of electricity or gas require licences, unless specifically excluded from doing so by the Secretary of State.
Ofgem determines the content of these licences, and has used them to require the establishment of a number of multilateral industry codes that underpin the gas and electricity markets.
These codes establish detailed rules for industry that govern market operation and the terms for connection and access to energy networks.
Modifying the codes
Each code can be modified and proposals to do so may be made by their signatories (generally network operators and those who use that network, although the categories of signatory do differ from code to code) or by consumer representatives (energywatch).
Each code has a panel or committee that oversees the assessment of proposed changes to that code.
For some kinds of proposed changes that body will also make the final decision on whether implementation is appropriate, but this is not always the case.
Some complete codes (such as the Balancing and Settlement Code or Uniform Network Code), or sub-sections of codes (such as Part 1 of the Distribution Connection and Use of System Agreement) may only be altered with the consent of, or at the direction of, Ofgem.
Our commitment to timely decision making
Our Corporate Strategy and Plan commits us to issue decisions on at least 70 per cent of proposed changes within five weeks of their reaching us for decision.
Right of appeal on decisions
The Energy Act 2004 introduced a right for market participants to appeal our decisions on proposed changes to industry codes to the Competition Commission, subject to that decision being eligible for this right.
The eligibility criteria are determined by the Secretary of State, who has the right to designate which kinds of decisions may be appealed. This designation may be subject to periodic review and change.
Currently, the Secretary of State has designated that decisions on the following codes are eligible to appeal:
• Balancing and Settlement Code;
• Connection and Use of System Code;
• Network Code;
• Supply Point Administration Agreement;
• Master Registration Agreement; and
• Uniform Network Code.
There are two specific exclusions from the right of appeal for the designated codes shown above. These exclusions are where:
• we are in agreement with the majority recommendation of the code's own governing panel; or
• we consider that the delay caused by holding an appeal against that decision is likely to have a material adverse effect on the availability of electricity or gas for meeting the reasonable demands of consumers in Great Britain.
The Competition Commission has provided guidance on its procedures for considering code appeals - a link to this is contained in the further resources panel to the right of this page.
