  • Kept your data for longer than necessary
  • Shared your data without a lawful reason

Providing proof of identity

We may ask you for proof of your identity (ID) before we investigate your complaint. This helps ensure that we are dealing with the correct person and that personal data is only shared with the right person.

We may ask you to provide:

  • One document with your photo, such as a passport or driving licence, and
  • One document showing your address, such as a recent utility bill or council tax bill

If you are complaining on behalf of someone else, we will also need:

  • An appropriate power of attorney; or
  • A signed letter of authority from the person you are acting on behalf of; and
  • Proof of their identity

If we do not have evidence that a third party is authorised to act on someone’s behalf, we will not investigate the complaint until we receive the appropriate authority. 

We only use identity documents to confirm who you are. They are kept securely and destroyed when no longer needed. 

What we will do

  • We will acknowledge your complaint within 5 working days
  • We will look into your concern fairly and carefully
  • We may contact you if we need more information
  • We will aim to provide a full response within 30 calendar days
  • If we require ID from you, the timescale for receiving a full response will commence from the date we receive your ID

If your complaint is complex and needs more time, we will explain why and keep you informed.

If you make a complaint using social media, we will ask you for an alternative, secure way of providing a response.

What could happen next

After reviewing your complaint, we may:

  • Explain how and why your data has been used
  • Correct inaccurate or incomplete information
  • Change how we handle personal data
  • Apologise if we have made a mistake
  • Take steps to prevent the issue happening again
  • If we believe we have complied with data protection law we will explain this to you

If you are not satisfied

If you are unhappy with our response, you have the right to complain to the Information Commissioner’s Office (ICO), the UK’s independent authority for data protection.

Keeping records

We keep records of data protection complaints and how they are handled. These records are kept securely and only for as long as necessary.

Changes to this procedure

This procedure may be updated to reflect changes in the law or guidance.
