What does a change in persons with significant control tell a UK seller?

A persons with significant control (PSC) change on Companies House means the people who own or control a company have changed. It can point to a sale, a new investor or a founder stepping back, so the people who decide what the company buys may be different. It is a reason to ask a question, not proof that a buying decision is coming. The record shows that control changed, not why.

What counts as significant control

GOV.UK statutory guidance says a PSC is usually someone who holds more than 25% of the shares or voting rights, or can appoint or remove a majority of the directors, or has significant influence or control over the company or a trust. Companies record share and voting levels in bands: more than 25% and up to 50%, more than 50% and under 75%, and 75% or more. A move between bands is therefore visible on the record.

Reading a change

Look at four things. First, whether someone has been added, ceased or changed band. Second, the date. Third, whether the new PSC is a person or another company, since a corporate owner suggests a group or acquisition. Fourth, whether the directors changed at the same time, which suggests a handover rather than a quiet transfer.

A new owner often reviews suppliers, systems and staffing, and that is when an outside seller has a way in. But a new PSC can also be a family transfer or a tidy-up of the register, with no change in how the company operates.

Using it in a call

Name what you saw and ask a plain question, such as whether the company has recently changed hands and how that affects its plans. Do not assume the previous owner has left or that the budget has moved. Pair the PSC change with another dated record, such as a director change or a new charge, before treating the company as a priority. Our guide on prioritising companies with buying signals covers how.

This week, 7 October 2026 to 14 October 2026, Lockley's index recorded 30,021 director changes filed, against 53,573 the week before. Director changes are a separate record from PSC changes, but the two often appear together.

Limits of the record

The PSC register depends on companies reporting accurately and on time, and it does not cover every owner. Some companies have no registrable person, and some give a statement instead. The register shows control as filed, so a very recent change may not appear yet.

Because of this, treat a PSC change as one input. Look at the website, recent news and the officers list to build a fuller picture, and write down what you found and when, so that the first call is specific and short. A seller who can say exactly what changed and when is more likely to be taken seriously than one who opens with a general pitch.
