Explained
What significant control means
Every UK company must keep a register of the people with significant control over it and file it with Companies House. Someone has significant control if they own more than 25% of the shares or voting rights, can appoint or remove a majority of the board, or otherwise have significant influence or control. Companies can also be controlled through another company, which then appears on the register itself.
