These notes are copied from a Gov.uk announcement today:
On 26 June 2017 changes will be made to UK anti-money laundering measures to help prevent money laundering and terrorist financing. It’ll increase the transparency of who owns and controls companies in the UK. This legislation will make changes to current requirements about people with significant control (PSC) information.
Impact on companies
From 26 June PSC information won’t be updated on the confirmation statement (CS01). Instead, you’ll need to tell us on forms PSC01 to PSC09 whenever there’s a change. You’ll have 14 days to update your register and another 14 days to send the information to us.
