Similar to previous years, early-bird tickets were released within days of the conclusion of the 2011 event, on 12 July 2011. Tickets remained on sale until the following Sunday. The second release of tickets went on sale at 9am on 2 December 2011, selling out within hours of release. The final release of tickets went on sale on 29 February 2012 at 9am. Tickets eventually sold out during the final days before the festival.
The Stone Roses were announced as the first headline act on 8 November, three weeks before the second release tickets went on sale. On 30 November, Vodafone customers who were signed up to the "Vodafone VIP" site were granted access to a pre-sale. The next day, T-Lady subscribers and past festival goers were also given access to the pre-sale. The second release tickets, equivalent to half of the venues capacity, went on sale to the general public on 2 December at 9am, hours later allocation was exhausted. Festival director, Geoff Ellis said that he was "delighted by the response from fans" and also noted that he "can’t wait to see everyone at Balado next year." Later he said: "The response to The Stone Roses announcement has been fantastic and the rest of the bill is shaping up nicely - we can’t wait until February to share it with the best audience in the world." On 10 December 2011, Geoff Ellis stated that "There will probably be an announcement on the headliners early in the new year." In an interview by Express.co.uk, he confirmed that there would be an announcement coming soon as they had just managed to increase the festival's first day capacity by 10,000 - which brings Friday inline with the capacity allowed on Saturday and Sunday, he noted this would increase the festivals opportunity to draw a bigger headliner for the Friday night.
