The Competition and Markets Authority (CMA) has secured formal commitments from Ticketmaster – known as undertakings – to improve the information made available to fans when buying tickets for gigs.

It follows widespread criticism of the way it sold tickets for Oasis’ comeback tour. Ticketmaster did not tell fans waiting in lengthy queues that standing tickets were being sold at two different prices, and that prices would jump as soon as the cheap tickets sold out; and it also sold some ‘platinum’ tickets at almost 2.5 times the price of ‘standard’ tickets – without sufficient explanation that these offered no additional benefits over some ‘standard’ tickets in the same areas of the venue.

Ticketmaster will be required to tell fans 24 hours in advance if a tiered pricing system is being used, as well as provide more information about ticket prices during online queues, helping fans anticipate how much they might have to pay. It must also not use any misleading ticket labels.
