Tesco is the UK's largest supermarket chain, with over 4,000 stores in the British Isles and a near-30 per cent share of the grocery market. The name itself, like many British retail names, predates the modern company and is the product of a single 1924 transaction.
The short answer
The name Tesco is a portmanteau formed from the initials T.E.S. and the first two letters of the founder's surname, Co. The T.E.S. comes from T. E. Stockwell, a tea supplier from whom the founder bought a large consignment of tea in 1924. The Co. is for Cohen, after the founder, Jack Cohen.
So Tesco = T. E. Stockwell + Cohen.
Who was Jack Cohen?
Sir John Edward Cohen, born Jacob Edward Kohen in 1898, was an East End market trader who began selling surplus NAAFI groceries in Hackney's Well Street market in 1919 with £30 of demob pay from the Royal Flying Corps. The 1924 tea deal with T. E. Stockwell was the first own-brand product the business sold, and the Tesco name was first printed on those tea packets.
From market stall to PLC
Cohen opened the first Tesco shop in Burnt Oak, north London, in 1929. By 1939 the company had over 100 stores. It floated on the London Stock Exchange in 1947 as Tesco Stores (Holdings) Limited.
The company's signature 1960s slogan, attributed to Cohen himself, was Pile it high, sell it cheap, a phrase that defined British discount grocery for two decades and is still cited in retail textbooks.
Common confusions
Tesco is sometimes claimed online to stand for Trade Especially Saving Customers Outlay. This is a backronym, invented decades after the fact, and has no basis in the company's records. The Stockwell-Cohen origin is documented in Tesco's own corporate history and in Cohen's authorised biography.
Why this matters
Tesco's name is one of the cleanest examples in British retail of a brand that has long outgrown the personal deal that produced it. T. E. Stockwell himself never had any further connection to the business, and the tea trade that produced the name has been industry-irrelevant for fifty years. The brand survived because it was short, distinctive and meaningless once detached, three useful properties for any name that has to last a century.
