Development Versions of each SEC Section are available to aid SEC Parties in understanding how the SEC is developing in between the designation of new versions of the SEC.
These show live content alongside any content that has been concluded on by BEIS but not yet designated by the Secretary of State (SoS). They also include text that is still undergoing consultation and has not yet been concluded on. The table at the beginning of each document provides a history of how each Section has evolved over time, with links to consultation and decision documentation.
You can find each Development Version of the SEC Sections 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.
