The Liberty 2 opened with a mix of retail and leisure tenants, although these were spatially separated[4] with the shops on the first two levels and the nightclub, cinema and bingo hall on the third floor.

As part of the revamp, the centre - which had previously still been heavily carrying the 'Liberty 2' branding - was rebranded under The Mall Fund's corporate identity.

The Mercury has been used as a filming location; for instance, it was featured in the Reebok "Belly's gonna getcha!"

[11] Since 2017 the Mercury has been the home of Romford Film Festival, showing movies over 5 to 6 days at the centres Premiere Cinema during the months of May or June.

The centre is iconic in Romford due to its glass dome enclosure, which is represented frequently in local art and illustration.
