Who owns a company, and how you can tell

Two separate things are public about who is behind a UK company, and people routinely confuse them.

Officers are not owners

Officers are the directors and the company secretary. They run the company. The register gives you their names, roles, appointment and resignation dates, partial dates of birth, nationality and a correspondence address.

A director might own the whole company, or none of it. Plenty of directors are employees. Plenty of owners are not directors.

People with significant control is the ownership record. Broadly, it captures anyone holding more than a quarter of the shares or voting rights, or who otherwise controls the company. Where the controller is another company, that appears as a corporate PSC, which is how you follow a chain upward.

If the question is "who is really behind this", PSC is the field you want. If the question is "who signs things", officers.

Why this matters more than it sounds

Most countries do not publish ownership at all. The UK does, for free, for every company. That single fact makes several things possible that are difficult elsewhere:

• Following a chain. A trading company owned by a holdco owned by another holdco is traceable to the top, one PSC record at a time.
• Connecting companies through people. The same director across nine companies is visible, and so is the group that nobody has named.
• Seeing structure that is deliberately quiet. Care groups, property portfolios and franchise networks frequently hold each unit in its own company. On the ground they look independent. Through officers and PSC they do not.

The caveats, which are real

PSC data is self-reported. A company files it. Nobody verifies it at the point of filing, and there have been well-documented cases of nonsense entries.

Not everything has a PSC. Some companies legitimately report no person with significant control, for example where ownership is spread thinly enough that nobody crosses the threshold.

Trusts and overseas entities complicate the chain. A chain can terminate somewhere that tells you less than you wanted.

Names are not identifiers. Two directors called the same common name are not necessarily the same person. Matching on name alone will merge people who should be separate. Date of birth month and year plus address helps, and is still not proof.

How to use it well

Start from the company, take the PSC, and if the PSC is a company, repeat. Note every officer, then look for those officers elsewhere. Cross-check against registered addresses, because a shared unusual address plus a shared director is a much stronger signal than either alone.

Then stop short of certainty. This data is very good at showing you where to look and it is not evidence on its own.

The short version

Officers tell you who operates. PSC tells you who owns. The connections between them, across companies, are the part that is genuinely hard to get anywhere else, and the part most people never open.
