SEC v5.22 came into effect on 18th September 2018. The Secretary of State has designated a new SEC Appendix AK and directed a consequential change to SEC Section A to reflect this.
The new SEC Appendix AK ‘SEC Variation Testing Approach Document for SMETS1 Services’ has been produced to explain how testing will be conducted by DCC as part of the SMETS1 Enrolment and Adoption.
You can download a zip folder containing SEC v5.22 here, or download the individual sections of the SEC from the SEC and Guidance Documents page of our website. The redlined changes to these documents can be downloaded here.
