List of supermarket chains in the United Kingdom

This is a list of supermarket chains in the United Kingdom. The UK supermarket sector is dominated by Tesco, Asda, Sainsbury's and Morrisons which are the only chains which operate full-scale superstores of 40,000 square feet (3,700 m²) or more. There are no regional supermarket chains left in the United Kingdom which operate superstores, just a few small ones which operate smaller stores. The "Big 4" had a combined share of 75.3% of the UK grocery market in the 12 weeks ending 2nd November 2008

The Co-operative Group is now the fifth largest food retailer in the UK, operating mainly smaller supermarkets and convenience stores, and having once been the UK's foremost retail force through its many local societies, followed by Waitrose in sixth place.

Marks and Spencer and Waitrose are the most upmarket national supermarket chains (although the former is also the UK's largest clothing retailer, and thus often is not perceived as a supermarket).
