Core data

We are responsible for the collection, monitoring and publication of rail customer complaints. ORR took on the data collection responsibility from the Department for Transport (DfT) in 2010.

ORR are responsible for monitoring compliance with how train operators handle customer complaints, this is known as the ‘Complaints handling procedure (CHP)’. The data we publish is used to monitor train and station operator’s compliance towards these policies.

Complaints data we publish

Every quarter we publish a range of data on the rail customer complaints, at both a national level and by train operator. The United Kingdom Statistics Authority designated these statistics as National Statistics. National Statistics status means that official statistics meet the highest standards of trustworthiness, quality and public value.

We publish the following complaints data, at both national level and by train operator.

  • Complaints rate per 100,000 journeys
  • Complaints by category - detail about the type of complaints made
  • Complaints by contact method - the method customers use to make a complaint
  • Complaints responded to within 10 and 20 working days and the train operators own target - the response to the complaints

The complaints data can be accessed on our Data Portal, with statistics made available by quarter and financial year.

Complaints data submission

Train operators must use the complaints template (found within the related documents) to submit data to ORR from April 2016.

We have produced guidance to explain the requirements for the data collection (also within the related documents section).

Guidance on complaints handling procedures for licence holders is available.
