How to complain

The best way to resolve a problem is usually through the officer you’ve been dealing with. You can do this over the phone, by email, in writing, or in person.

If the issue cannot be resolved locally, by the service involved, you may progress matters further by making a formal complaint through our helpdesk using the details below:

We take complaints about our service very seriously, as such, we strive to deliver a high quality of service at all times. We recognise that problems may sometimes occur and we are committed to dealing with all complaints promptly and in a fair and reasonable manner.

What happens next

We will acknowledge your complaint within 2 working days and let you have a full response within 20 working days. If it is not possible to respond fully within this timescale, we will write and let you know why and say when you should expect to receive a full response. Our corporate complaints procedure consists of 4 stages:

Stage 1: Business unit response

The relevant head (or director) of the business unit will investigate matters and provide a response explaining their decision and, where appropriate, any recommendations or action required.

Stage 2: Chief Executive response

Sending your complaint directly to the Chief Executive may delay the handling of your complaint so we always recommend making contact via the helpdesk. If you are unhappy with the stage 1 outcome, please get back in touch with the helpdesk. Let us know why you are unhappy with the decision and what you think we can do further to help.

Please note that the Chief Executive cannot review any new or different issues and they will only usually consider your complaint after the stage 1 procedure has been completed. The Chief Executive will then review your original complaint and the response provided and will make a decision about whether or not matters have been dealt with appropriately.

Stage 3: Department for Transport’s (DfT’s) Independent Complaints Assessor (ICA)

If you are unhappy with the final response provided by the Chief Executive, you may get back in touch with the helpdesk and ask to refer your complaint to the ICA. The ICA will carry out an independent review of the case and then advise both parties on the outcome of their decision.

Stage 4: Parliamentary and Health Services Ombudsman (PHSO)

After review by the ICA, you may seek advice from any Member of Parliament (MP) and ask them to refer your complaint to the PHSO.
