The ICO exists to empower you through information.

Mae’r gwasanaeth yma yn cael ei adolygu ar hyn o bryd a bydd yn ddwyieithog cyn gynted â phosib. Ymddiheuriadau am unrhyw anghyfleusterau. This service is currently under review and will be available bilingually as soon as possible. We apologise for any inconvenience.

Use this service to find out what to do next if you're unhappy with how an organisation has handled your personal information.

This service will help you decide if we're the right organisation to complain to about your experience. You'll then submit an online complaint form, which will be assigned to one of our case officers within 14 weeks.

What you'll need

You'll need:

  • a copy of the complaint you have made to the organisation about how they have used your information; and
  • a letter of consent from the person the complaint is about, if you are complaining for someone else.

It is helpful if you can also provide:

  • any supporting information you have of the misuse of your information eg a copy of an email where your information was shared, copy of records with inaccurate information, an apology letter from the organisation, or other email exchanges. 

If you don't have this information call us on 0303 123 1113 or live chat with us so we can help you decide what to do next.

What will the outcome of my complaint be?

There are a number of possible outcomes to your complaint, the most common are:

  • We tell the organisation to take action. We might tell them to do more to help you get the result you want, explain their decision to you more clearly or to make changes so similar issues don't happen again. 
  • We don't take action. Despite the difficult experience you've had with the organisation, it might be that they have followed the law - this means we're unable to take any action. There might also be times we find the organisation was at fault but we're happy with how they managed the issue and we chose not to take action.
