On the 10 February 2011 the Secretary of State extended the public transport ticketing schemes block exemption (Ticketing Block Exemption) by a further five years until February 2016. The Ticketing Block Exemption provides a ‘safe harbour’ for integrated ticketing systems from the prohibition under UK competition law against companies entering into price-fixing arrangements. The exemption allows transport companies to agree terms for multi-operator travel cards, e.g. the ‘Oyster’ card. According to an explanatory memorandum by the Office of Fair Trading (OFT) supporting the extension of the current regime, the integrated ticketing systems deliver benefits for passengers and transport operators. The main benefits identified are improvements in the quality and flexibility of transport services and the viability of public transport networks. The OFT considered that these advantages outweigh any negative effects such schemes might have on competition between transport companies.
