SEC v33.0 released to implement MP111

25 January 2021

An updated version of the SEC came into effect on 25 January 2021 to implement MP111 ‘SMDA Budget Amendments’.


MP111 ‘SMDA Budget Amendments’

MP111 will bring the Smart Meter Device Assurance (SMDA) Scheme under SEC governance and funding. The SMDA Co Board will become a SEC Panel Sub-Committee (SMDASC) and the SMDA Management Panel will become a Sub-Group of the SMDA Sub-Committee.

The fixed costs of running the SMDA Scheme will be funded via the SEC Panel budget. The SEC Panel will oversee the SMDASC and the Smart Energy Code Company (SECCo) will become responsible for contracting with the Test House(s). This will bring the essential task of assuring interchangeability and interoperability under the SEC where long-term funding can be ensured.

  • SEC Section A ‘Definitions and Interpretation’
