Index was a catalogue retailer in the United Kingdom, that was owned by Littlewoods from 1985 until 2005.

It was a well known retailer in the 1980s and the 1990s, but sales declined in the noughties and it lost many customers to its main rival, Argos.

Index failed to make a profit in eighteen of its twenty years of retailing, losing more than £100 million in total.

[2] In 2005, Littlewoods announced the closure of all its eponymous high street stores, which also meant the closure of any Index branches that shared their location with a Littlewoods department store.

The company closed all Index branches in April 2005.
