Maintaining the PSC register

What it does

The PSC Register is your statutory record of People with Significant Control under sections 790A-790ZG of the Companies Act 2006. Every UK private company must maintain one — even if the only PSC is the sole founder holding 100%.

A PSC is someone (or some entity) who:

• Holds ≥25% of the shares, OR
• Holds ≥25% of the voting rights, OR
• Has the right to appoint or remove a majority of directors, OR
• Has significant influence or control by other means (e.g. veto rights, trustee of a substantial shareholding)

How to add a PSC entry

1. Go to Company → PSC Register
2. Click Add PSC
3. Enter the PSC's name
4. Pick the type:
   • Individual — natural person
   • Corporate entity — UK or overseas registered company
   • Other legal person — trust, partnership, etc.
5. Set the notification date — the date the PSC condition was met (e.g. the date they acquired their qualifying shares)
6. Select the nature(s) of control — at least one is required. Tick all that apply:
   • Ownership of shares: 25-50%, 50-75%, or 75%+
   • Voting rights: 25-50%, 50-75%, or 75%+
   • Right to appoint/remove a majority of directors
   • Significant influence or control
7. For individuals: fill in DOB (YYYY-MM), nationality, country of residence, service address
8. For corporate / legal-person PSCs: fill in company number + registration country + service address
9. Click Add to register

When a PSC ceases

When a person/entity stops being a PSC — for example after diluting below 25% in a funding round — open their row and set the cessation date. The entry is preserved (required by s790ZG) but moves out of the active list.

Tips

• The PSC register must be populated even if you have only one PSC. An empty PSC register is a CA2006 offence — you'd need an explicit "no PSC" entry instead (rare).
• The nature-of-control codes match Companies House's schema, so you can later file PSC02 forms directly from this data when CH eFiling ships (Phase 4).
• An individual founder holding 100% of voting shares satisfies all three categories: 75%+ shares, 75%+ voting, and director-appointment rights. Tick all three.
• Download the s790 register as a PDF any time via the Register button at the top of the page.
