The Companies House register, which can be viewed by anyone, contains only the full name of the partner and the month and year of birth. The address and date of birth of a person with significant control in an SLP are not included on the public register, but this data can be provided on request to authorities.
You can limit access to your personal data by writing to Companies House if you have a valid reason.
The government authorities usually make concessions for a person with significant control and remove their personal data from the public register if they or their relatives are at risk of being attacked or threatened. Another reason for the request may be that the applicant belongs to a religious community whose rules prohibit members of the community from entering into commercial partnerships.
