It is owned by parent company the NEC Group. When it was opened in 1991, it was the largest indoor arena in the UK.

The arena is located alongside the Birmingham Canal Navigations Main Line's Old Turn Junction and opposite the National Sea Life Centre in Brindleyplace. The building straddles the main Birmingham to Wolverhampton Intercity railway line (originally the Stour Valley Line), but does not have a station of its own. There are three adjoining car parks with a total of 2156 spaces. Close to the arena is The ICC which is also owned by the NEC Group.

It is currently the third-largest indoor arena in the United Kingdom by capacity. In 2019, the arena had ticket sales of 530,597, which was the 4th highest in the United Kingdom.
