Signs will be displayed notifying you of our CCTV arrangements. The Crown Estate provides surveillance services with the primary purpose of preventing and detecting crime. Retention policies are in place to govern how long this information should be kept, which is generally for no longer than 30 days unless an incident has been logged. More information on access control and visitor management is provided below.

Access control and visitor management

At One Heddon Street, we provide an access control system that allows secure entry to the building, and/or details of visitors to your premises. We deliver these services at the property pursuant to leasing agreements, as well as to prevent and identify crime. These systems hold personal data – typically an individual’s name, the organisation with which they are associated and movement data as they access various parts of the building.

For the purposes of providing access control services to you, The Crown Estate’s managing agents act as your data processor. In relation to any subject right requests for the personal data included in the access control systems and/or visitor systems, The Crown Estate’s managing agents will refer requests to us as the data controller and respond to your instructions as to how these should be actioned. To ensure compliance with data protection laws, The Crown Estate’s managing agents will review personal data within any access control and visitor systems, and any personal data relating to expired access cards will be permanently deleted.

Location information

When you use our app for room booking, and consent to location services being used by it, low energy bluetooth is used to broadcast a unique meeting room ID so that the app knows when you are close to the meeting room and prompt you to book it.

Transfers of personal data

Where necessary, The Crown Estate may transfer your personal information to its joint venture partners, suppliers or service providers based outside the European Economic Area (EEA). If The Crown Estate does this, your personal information will continue to be subject to one or more appropriate safeguards as required by law.

The Crown Estate will ensure that where information is transferred outside the EEA, transfers will only take place where appropriate safeguards are in place to protect it, such as standard contractual clauses or binding corporate rules. Further information on such transfers are included below under ‘Service providers’.
