DO NOT UNDER ANY CIRCUMSTANCES use this company. I ordered, paid for and did not receive 2 tickets (one of which was a present for someone) despite several re-assurances (by email only, no telephone contact available) by the UKT (!) team.
I was told the tickets would arrive 7 days prior to the concert (November) despite paying for them in August, only to be told 1 day before the event that they had been let down by their suppliers. When I demanded a full refund I was sent a link to a financial services website showing how to claim from my bank! Very disappointed, I was angry but have calmed down a little now!
