Development of SEC Sections

To aid SEC Parties in understanding how the SEC is developing overtime, in between the designation of new versions of the SEC, we have put together Development Versions of each SEC Section. 

These show live content alongside any content that has been concluded on by BEIS but not yet designated by the Secretary of State (SoS) and text that is still undergoing consultation and has not yet been concluded on. Also provided is a history of how each Section has evolved overtime, with relevant links to consultation and decision documentation.

You can find each Development Version of the SEC Section under the documents section on this page.

Please note, these documents are provided for reference only as the content in these Development Versions may differ from what is formally designated by SoS.

BEIS has issued an open letter for information on its planned approach to a staged implementation of the remainder of the SEC to support the revised DCC Plan. This letter on SEC arrangements can be found
