Complaints procedure

How to complain if you’re unhappy with the service you get from clean air zones.


If you’re unhappy with the service we’ve provided

You must first contact the department that you’ve been dealing with (this is the quickest way to resolve your issue). To deal with your concerns you’ll need to tell us:

  • your full name and address

  • your vehicle registration number, including the make and model of the vehicle

  • any reference number we’ve provided on previous correspondence

If you’ve spoken to the department but your issue has not been resolved, follow the process below to make a formal complaint.

Making a formal complaint

If you’ve tried to resolve matters with the department you’ve been dealing with and you are not happy with the outcome, write to our complaints team telling them your concerns.

If you have not tried to resolve the issue before writing to our complaints team, we’ll get the relevant department to reply to you.

To make your complaint, contact our complaints team or write to:

  • Complaints Team
  • Clean Air Zones
  • DVLA
  • Swansea
  • SA6 7JL

We’ll acknowledge receipt of your complaint and aim to send you a full reply within 10 working days. However, due to the COVID-19 pandemic, it may take us longer than usual to review your case, so please bear with us.

An independent review

If you think your complaint has not been resolved through our 2 step formal complaints procedure, you can ask us to refer your complaint to an Independent Complaints Assessor (ICA).

They’ll review the way your case was handled and will expect you to have tried to resolve your complaint directly with us, in line with our complaints procedure, before they consider your complaint. Find out more information about what the ICAs cover.

Parliamentary and Health Service Ombudsman

If you are not satisfied and you’ve had your complaint investigated by the ICA, you can ask a Member of Parliament (MP) to refer your complaint to the Parliamentary and Health Service Ombudsman.
