What is PSC Register?
The PSC (Persons with Significant Control) register lists individuals who have significant control over a company - typically those with 25%+ shares or voting rights.
How PSC Register Works in Practice
Step by Step
When a company is incorporated, it must identify its PSCs and establish the register immediately. The company has a legal duty to take reasonable steps to find out if there are any PSCs and to obtain the required information from them. If you are a PSC, you have a legal obligation to respond to the company's requests for information within one month.
Whenever there is a change - for example, a share transfer that takes someone above or below the 25% threshold, or a change in a PSC's details - the company must update its own PSC register within 14 days of becoming aware of the change. The company must then file the updated information at Companies House as part of its next Confirmation Statement, or it can choose to file the change immediately using the online service.
If a person fails to respond to a PSC information request, the company can issue restrictions notices that freeze their shares - preventing them from transferring shares, exercising voting rights, or receiving dividends until they comply. This is a powerful enforcement mechanism, although it is rarely used in practice among small companies.
Companies that have elected to keep their PSC register on the Companies House central register do not need to maintain a separate register but must still ensure the central register information is accurate and up to date.
Practical Tips
Common Mistakes to Avoid
- Not updating the PSC register when shares are transferred between individuals, even within the same family - any change in control above or below the 25% threshold must be recorded
- Recording the PSC's home address as their service address without realising it will be publicly visible on the Companies House register - use a service address for privacy
- Not identifying indirect PSCs who control the company through another entity, such as a holding company or trust - the rules look through the corporate chain to find the ultimate individual
- Failing to file PSC information at Companies House within the Confirmation Statement, which can result in the Confirmation Statement being rejected
