From the DVSA:

We have launched a new online portal for our customers who wish to make a complaint or send positive feedback.

We’re committed to providing a high quality of service to everyone, but we need you to tell us if we get things wrong. We’ll listen to your complaint and treat it seriously and in confidence.

This new portal is part of our commitment to providing the best and most efficient service possible to customers.

What this means

When using the online portal, you will be asked for necessary information up front as part of the complaint or feedback submission. This will make the process more efficient.

How to give feedback

Information on how to make a complaint is available on GOV.UK, where you will also find the new portal.

Providing excellent customer service

As this is a new element of our complaints service, we will be using the initial few weeks to assess how well it is working for our customers and make any necessary changes.
