RSP accreditation

What is accreditation?

Accreditation is the process by which Rail Settlement Plan (RSP) ensures that Ticket Issuing Systems (TIS) used to sell and issue National Rail tickets for travel on passenger train services in Great Britain:

  • produce tickets that conform to industry standard specifications (RSP Standards), so that they can be accepted by all Train Operating Companies (TOCs) and thus support interoperability across all TOCs in line with the Ticketing & Settlement Agreement (TSA);
  • generate the associated ticket transaction data ensuring it conforms to the relevant RSP Standard and is therefore acceptable to the centralised RSP settlement systems, to ensure accuracy and probity of settlement;
  • generate data which interfaces appropriately with other RSP systems and allows for interoperable functionality between TIS for seat reservations, Ticket on Departure (ToD) and other systems;
  • maintain RSP Standards of security and integrity in relation to RSP systems;
  • assure TOCs that their TIS comply with the terms of the TSA, and assure third party retailers that their TIS comply with the terms of their retailing licence;
  • ensure that the TIS uses RSP standard data feeds in their retailing processes to meet consistency and impartial retailing requirements; and
  • support disaster recovery/business continuity and recovery from system fault conditions, error handling and preserve an audit trail.

Who has been accredited?

This document is published to record the current accreditation status of public facing websites and apps which retail National Rail tickets.

TIS which achieve accreditation will display the National Rail Mark of Accreditation. Only websites and apps which are listed in this document should display the National Rail Mark of Accreditation:

TOC websites are listed to provide a cross reference to the TIS supplier which provides the TOC core retailing functionality. This may be a different supplier to that which provides the website presentation layer.

TOC websites which declare themselves to be impartial retailers must offer impartial retailing of all products in the RSP data feed between all National Rail stations as required by the Ticketing and Settlement Agreement. TOC websites which declare that they are not impartial may restrict the selection of products available, providing that the limitations on retailing is made clear to the user.

How do I get accredited?

In summary, there are two ways of accessing RSP accreditation services:

  • RSP Accreditation Contract - The TIS Supplier enters into an RSP accreditation contract which offers agreed levels of coverage at a contract rate which is equivalent to less than £1000 per day during the term of the agreement. This allows both the TIS Supplier and RSP to effectively and efficiently plan accreditations in terms of resources and budgets over the course of a financial year.
  • Non Contractual Accreditation - The TIS Supplier requests accreditation and submits their proposal. RSP estimates the time required to undertake the accreditation based on the proposal received and then offers an accreditation slot at a rate of £1000 per day. TIS Suppliers using this arrangement should consider making their proposal to RSP at least 3 months in advance of the date on which they would like the accreditation to commence as it is a 'first come first served' non contractual service.
