Code Administrators Code of Practice


Code Administration Code of Practice

The Joint Office is committed to operating in line with the Code Administration Code of Practice, published by Ofgem.  Any comments on the Code of Practice or how we can better comply with this would also be very welcome at any time  - email


What is the CACoP?

As part of Ofgem’s Code Governance Review, the Code Administration Code of Practice (CACoP), was established.

The CACoP is a cross energy industry code document and aims to provide consistency in the approach and level of service associated with Codes modification processes. 

The CACoP contains a number of key principles to facilitate consistency, convergence and transparency in code Modification processes and to help protect the interests of small market participants and consumers through various means including increased use of plain English in Change Reports.


Cross Code Engagement (Modifications affecting multiple Codes)

In order to encourage Cross Code Engagement across the industry, Code Administrators have agreed how they will support any modifications affecting two or more Codes.  This is detailed in the Code Administration Joint Working Practice available at:

The Master Registration Agreement (MRA) website also publishes a regsiter of modifications which may have cross code impacts at: 


CACoP Committee

The Chair and Secretariat services for the CACoP changes every 12 months between each Code Administrator in alphabetical order per Code. From 01 January 2018 to 31 December 2018, this will be the responsibility of DCUSA.  Information with regards to the CACoP Committee meetings and activities can be found via the DCUSA website here


CACoP Committee News (October 2018)


Code Administrators (CAs) and Ofgem have identified areas of their respective Codes that will likely require changing post-Brexit. The extent of the changes will vary from one Code to another, and, similarly, the level of input required from Ofgem will vary also. 

Each Code is looking to identify where changes may be required to ensure fitness for purpose from the day the UK leaves the EU. It is the intention to undertake the requisite changes via the normal Code Modification process.

At present, CACoP have not identified any Code provisions that would be legally inoperable on exit day. Each Code has identified a number of non-substantive changes that would be required, for example, to remove references to EU law. However, until the Government publishes details of how EU legislation will be incorporated into UK law, we will not know the full details.

CAs will continue to work with Ofgem to ensure Ofgem and BEIS are aware of Code specific issues and concerns, so they can account for any flagged issues when preparing draft legislation. This will help to ensure continuity from 30 March 2019 onwards, and in the longer term, depending upon the UK’s relationship with the EU, and more specifically, GB’s relationship with the European Internal Energy Market.

CAs will ensure that their stakeholders are informed of any announcements that will impact Industry Codes as soon as possible. 

National Grid will be raising the UNC Modification Proposal and further details will be shared once they are available.
