The head office and main factory are based in the town, and the company has another site in Wesham in Lancashire.

The business is known for mass-market and chocolate-covered biscuit bars such as Rocky, Classic, Echo, Crunch Creams and Party Rings.

The company was founded in 1853 in a terraced house, 17 Whitaker Street, in Batley in West Yorkshire by Michael Spedding, who worked from his small bakehouse making "eatables" to sell at feasts and fairs held throughout the north of England.

His daughter Hannah provided the name for the company when she married Fred Ellis Fox in the late 1800s.

On 28 May 2008, Fox's Biscuits launched a TV ad campaign and £5 million marketing campaign[7] centred on "Vinnie", a "danda", cross between a dog and a panda, meant to be Fox's "number one fan" who had travelled across the Atlantic to make sure everybody knew who makes his favourite biscuits (which he mispronounces with a "w" instead of a "u").
