PSC compliance for UK company groups
PSC Register Software for UK Companies
PSC compliance done by the system, not by hand. Auto-detect new PSCs, calculate look-through ownership and notify Companies House inside the 14-day window.
Your first entity is free. No credit card required.
EntityFlo maintains the PSC (People with Significant Control) register for every UK company in your group. It detects PSCs across complex ownership chains, generates PSC01/02/04/07/09 notifications, and tracks the 14-day window required by Companies House.
What breaks once you pass five entities.
Ownership through trusts and holdings is hard to track by hand
A PSC hiding three layers deep in a structure is easy to miss without a system doing the look-through calculation.
The clock starts the moment ownership changes
Not when someone notices, which means manual processes are almost always behind by the time they catch a PSC change.
Getting it wrong is a criminal offence
Failure to maintain the PSC register or notify Companies House carries fines and, in serious cases, imprisonment for officers.
Look-through ownership, calculated automatically
EntityFlo looks through every intermediate entity in your structure, applying the same logic to trusts, partnerships and foreign parents.
Look-through calculation
If a UK company is owned 60% by a holding company owned 50% by an individual, that 30% effective interest is surfaced as a PSC automatically.
The 14-day rule, covered
PSC changes are detected the moment a cap table movement, trust change or director appointment triggers one.
The full PSC form suite
PSC01, PSC02, PSC04, PSC07 and PSC09 are all generated pre-filled from your live data.

What PSC compliance actually requires
A PSC is anyone holding more than 25% of shares or voting rights, with board appointment rights, or with significant influence or control: including through trusts and holding structures.

EntityFlo vs. spreadsheets vs. other PSC tools
Most tools track PSCs entity by entity. EntityFlo calculates look-through ownership across the whole group automatically.

Because We’ve Done the Work Ourselves.
EntityFlo was built by people who understand the complexity, risk and manual work behind managing corporate groups.
"We went from spreadsheets and email chains to having every entity, every officer, and every deadline in one place. The compliance AI alone has saved us from three potential ASIC penalties."
"EntityFlo's structure charts finally gave our board the visibility they needed. Every ownership chain mapped, every UBO calculated. The lenders were impressed."
"Managing 40+ trusts and companies across three generations was chaos. EntityFlo made it simple. The compliance alerts alone are worth the price."
One flat monthly rate. Scales with your group.
No per-document fees. No per-filing fees. No paywalled AI tier.
The questions buyers actually ask.
What is an RLE?
A Relevant Legal Entity: a UK-registered company that meets PSC conditions in its own right and sits in the ownership chain. RLEs are reportable instead of looking through them.
Do I have to keep an internal PSC register?
Yes. Every UK company must maintain a PSC register at its registered office or SAIL address. EntityFlo generates a Companies Act-compliant register on demand.
What are the penalties for getting this wrong?
Failure to maintain the PSC register or notify Companies House is a criminal offence: fines and, in serious cases, imprisonment for officers. Most failures are administrative; EntityFlo eliminates the administrative risk.
Does this work for LLPs?
Yes. LLPs are subject to the PSC regime and are tracked alongside companies in the same register.
How does the look-through calculation work?
EntityFlo traces ownership through every intermediate entity: holding companies, trusts, foreign parents: to identify individuals whose effective interest crosses the PSC threshold.
