Please note that from 22 March 2021, the Standard TR-1 Form should be completed and submitted to the FCA via our Electronic Submission System (ESS) in relation to notifications of voting rights held in issuers whose shares are admitted to trading on UK regulated markets.

Holders of voting rights in issuers whose shares are admitted to trading on UK prescribed markets such as AIM market, can continue to use this form to send their notifications to those issuers. Alternatively, if they wish they can register on ESS to be able to notify to us, produce a TR-1 Form via ESS and submit the downloaded version to issuers with shares admitted to trading on  prescribed markets.
