SI Registration

SI Registration Toolbox

Legislation.gov.uk Publishing is an online system for registering and publishing legislation provided by The National Archives (TNA), in conjunction with our contracted legislation publisher – The Stationery Office Limited (TSO). Further details about the relationship between The National Archives and The Stationery Office can be found in About Us and in the Publishing Toolbox. 

This toolbox is designed to provide users with information on how to submit SIs and associated documents for registration and onward publication. It is also intended to provide an insight into the SI Registration process.

In this section, where it is recommended that the SI Registrar be contacted, please email siregistrar@nationalarchives.gov.uk or phone 020 8392 5361.
