The Smart Energy Code (SEC) is a multi-Party agreement which defines the rights and obligations of energy suppliers, network operators and other relevant parties involved in the end to end management of smart metering in Great Britain.

The SEC comes into force under the Data and Communications Company (DCC) Licence, which has been established to manage the smart metering communications infrastructure. 

The DCC, energy suppliers and network operators are required by license to become a party to the SEC and comply with its provisions. Other bodies who wish to use the DCC’s services must also accede to the SEC to do so. 

The SEC is self-governed and is managed by the SEC Panel  with oversight where appropriate from Ofgem.

The objectives of the SEC are to:

  1. Facilitate the efficient provision, installation, operation and interoperability of smart metering systems at energy consumers’ premises within Great Britain;
  2. Enable the DCC to comply at all times with the objectives of the DCC and to discharge the other obligations imposed upon it by the DCC Licence;
  3. Facilitate energy consumers’ management of their use of electricity and gas through the provision of appropriate information via smart metering systems;
  4. Facilitate effective competition between persons engaged in, or in commercial activities connected with, the supply of energy;
  5. Facilitate innovation in the design and operation of energy networks to contribute to the delivery of a secure and sustainable supply of energy;
  6. Ensure the protection of data and the security of data and systems in the operation of the SEC;
  7. Facilitate the efficient and transparent administration and implementation of the SEC.

The SEC was officially first designated by the Secretary of State for the Department for Energy and Climate Change on 23rd September 2013. Newer versions of the SEC have been designated by the Secretary of State since then.
