How to make a data protection complaint to the Department for Business and Trade

We are committed to handling your personal data in a way that is fair, transparent and in accordance with the law. If you are dissatisfied with how we have handled your data, this process outlines how you can make a complaint.

How to make a complaint 

If you have a complaint about how your data has been handled, you can complete the Department for Business and Trade’s (DBT) short online Data Protection Complaint form

This allows us to investigate and resolve issues as quickly as possible. 

When you contact us, provide as much detail as possible about your complaint. This will help us understand the issue and investigate it thoroughly. 

What you can expect from us 

We will acknowledge receipt of your complaint within 30 days. We will then investigate your complaint and provide you with a full response without undue delay.

We will: 

  • provide you with a clear and comprehensive outcome of our investigation
  • request any additional information we may need from you in a timely and proportionate manner to deliver our response

If you remain dissatisfied

If you are not satisfied with the outcome of your complaint, or if you feel we have not handled it appropriately, you have the right to complain to the Information Commissioner’s Office (ICO). The ICO is the UK’s independent regulator for data protection and information rights.
