Warburtons is a British baking firm based in Bolton, Greater Manchester, England. The firm produces one million bakery products per day. The company employs around 3,300 people at eleven bakeries across the United Kingdom. It is the UK's third biggest bread manufacturer after Allied Bakeries and RHM (British Bakeries). It makes no own-label products, just its own.
Warburtons grew with the purchase of several smaller companies in the north west of England. The firm continued to expand and the 1990s saw the construction of new bakeries at Eastwood in Nottinghamshire, Bellshill and Wednesbury. In October 2003, HRH the Duke of Edinburgh opened Warburtons eleventh bakery in Enfield, North London. In 2004, Warburtons increased production in Scotland with completion of Bellshill, phase two. Rathbones Bakeries, based in Walsall, went into administration in April 2005, and Warburtons bought a bakery at Stockton-on-Tees just off the A66 near Preston-on-Tees in January 2005, and another bakery at Rogerstone near the A467 at Newport in November 2005. A new £60m 12 acre super bakery in Castleford, West Yorkshire opened in March 2006. It is the largest bakery in Europe. Other bakeries outside of the Greater Manchester area are in Newburn for Newcastle-upon-Tyne next to the A6085 and River Tyne.
The 'official' Bread World Cup in 2006 saw Warburton's Toastie Bread in the final, and winning the World Cup itself after seeing off over 32 other varieties in a straight knock out competition.
