To comply with UK GDPR, one of the first steps for landlords is to identify what tenant personal data they will be processing.
Personal data is information that can make your tenant identifiable and includes:
dates of birth
Processing is any use of personal data (other than for personal reasons) and includes storing, recording and obtaining. For more information, read Processing personal data.
Landlords should ensure that they conduct an audit to assess their data processing activities to establish the data they hold, who it is shared with and how long it is stored.
