The company was founded in 1945[2] by Charles Brook, and the name supposedly arose because of an error in a photo-processing shop; instead of writing "C. Brook" on a film, a clerk wrote "Seabrook".

[3] Seabrook's crisps are distributed widely in the north of England, and increasingly in the south, and are also sold through mail order.

Most of the potatoes used by the company are grown within 50 miles of the Bradford headquarters, Seabrook House.

In 2017, Seabrook Crisps employed about 150 people, and was 75% owned by LDC (Lloyds Development Capital) and 25% by the management team: Jonathan Shuttleworth (CEO), Daniel Woodwards (COO), Jon Wood (commercial director) and Paul Monk (chairman).

In October 2018, Seabrook Crisps was acquired by the UK subsidiary of Japanese snack company Calbee.
