From 6 April 2016 most companies, LLPs and Societates Europaeae are required to hold a register of people with "significant control". This is in addition to other information, such as registers of members and directors, and from 30 June 2016, LLPs and SEs must provide this information annually to Companies House when making the new Confirmation Statement. A statement of initial significant control will also be required from 30 June when applying to incorporate a new company, LLP or SE.

Reasonable steps must be taken to identify people with "significant control" and the new set of regulations set out what that means. In the case of a company, people with significant control include an individual who holds more than 25% of shares or voting rights or has the right to appoint or remove a majority of the board of directors.
