If you are processing personal data as part of your political campaigning activities, you will need to comply with the UK General Data Protection Regulation (UK GDPR).

Personal data includes, but is not limited to, names and addresses from the electoral register, the marked register and of your members. It also includes any information an individual has provided to you or any information you infer about individuals.

If you contact individuals to promote a political view or to otherwise influence them, this is considered direct marketing, which is also regulated by UK GDPR and the Privacy and Electronic Communications Regulations (PECR). Direct marketing includes contact by:

  • post;
  • email;
  • text or similar message;
  • voicemail; and
  • phone or automated calls.

Paying the data protection fee

On 1 April 2019, the rules around paying the data protection fee changed. Members of the House of Lords, elected representatives and prospective representatives (including police and crime commissioners) are exempt from paying a fee, unless they process personal data for purposes other than the exercise of their functions as a Member of the House of Lords, an elected representative or as a prospective representative. For more information, read our guidance on the data protection fee.
