Consultation on additional Smart Energy Code (SEC) content

Further consultation on additional policy and proposed legal text on the Smart Energy Code (SEC).

Last fetched 03 May 2026 · gov.uk
Detail

This document consults further on additional policy and proposed legal text on:

  • Smart Metering Key Infrastructure (SMKI)
  • DCC Key Infrastructure (DCCKI)
  • Infrastructure Key Infrastructure (IKI)
  • Shared Services
  • additional security requirements
  • moving some detailed and technical SEC text into a subsidiary document

This document also provides the government response to consultations on:

SEC Section H5.33-5.40 (Post Commissioning obligations)

Please note that a separate version of the post commissioning obligations has also been provided. Please note that it is intended that this text will be moved to a subsidiary document as part of the more general changes proposed for H5. However government is consulting on further changes to the post commissioning obligations that would be placed on suppliers and the DCC (and which would, if incorporated, ultimately be included within the new subsidiary document under Section H5), although for convenience the legal drafting at this stage shows the amendments that would be made to the version of Section H5 we consulted upon as part of the SEC 4 consultation. As it is not now proposed to be part of the main body of the SEC, we are publishing the text separately. We are also consulting on complementary changes to Section M which support the proposed changes to these proposed post commissioning obligations.

We have noted an error in the ‘SEC4A and Transitional Arrangements government conclusions and further consultation text’ and ‘Smart Energy Code with SEC4A and Transitional Arrangements conclusions incorporated - clean’ documents. The correct definitions of DCC User Interface Specification and DCC User Interface Services Schedule are:

  • DCC User Interface Specification means the SEC Subsidiary Document identified as the ‘DCC User Gateway Interface Specification’ set out in Appendix [TBC].
  • DCC User Interface Services Schedule means the SEC Subsidiary Document of that name set out in Appendix [TBC].

We will amend the in force legal text at the earliest opportunity and apologise for any confusion caused.
