Welcome to the Smart Energy Code

With the outbreak of COVID-19, we hope you are faring well during this unusual time. We want to assure you that all SECAS services are running as normal, and organised meetings will be hosted online.

​​​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 former Department of Energy and Climate Change (now the Department of Business, Energy and Industrial Strategy) issued the designation of the SEC and the Charging Methodology on 23 September 2013 following the granting of the DCC Licence.

The designation letter identified the members of the SEC Panel and Gemserv as the company which will act as the Smart Energy Code Administrator and Secretariat (SECAS).
