Tesco is one of those brands that feels like it has always been part of British life — and in many ways, it has. Tesco plc is a British multinational groceries and general merchandise retailer headquartered in Welwyn Garden City, England, and is the market leader of groceries in the UK with a market share of around 28.4%. But who actually owns Tesco today? It’s a question more people should ask — because the answer reveals just how much Britain’s favourite supermarket has changed since its humble beginnings.
The short answer: Tesco PLC is listed on the London Stock Exchange under the ticker TSCO, and is now primarily owned by institutional investors, who collectively held 82% of the company’s shares as of June 30, 2025. The largest single shareholder is BlackRock, Inc., holding 9.0% of outstanding shares. Here’s the full story of how Tesco went from a single market stall in East London to one of the world’s largest retailers.

The Founder — Sir Jack Cohen
Jack Cohen, the son of Jewish migrants from Poland, founded Tesco in 1919 when he began to sell war-surplus groceries from a stall at Well Street Market, Hackney, in the East End of London. The Tesco brand first appeared in 1924. The name came about after Jack Cohen bought a shipment of tea from Thomas Edward Stockwell — he made new labels using the initials of the supplier’s name (TES), and the first two letters of his surname (CO), forming the word TESCO.
Jack Cohen opened the first Tesco shop in September 1931 at 54 Watling Avenue, Burnt Oak, Edgware, Middlesex. Tesco was floated on the London Stock Exchange in 1947 as Tesco Stores (Holdings) Limited.

Leadership — Then and Now
The current leadership includes key figures like Dr. Gerry Murphy as Chair and Ken Murphy as Group Chief Executive, supported by Chief Financial Officer Imran Nawaz and Senior Independent Director Dame Carolyn Fairbairn DBE. The board is further strengthened by independent Non-executive Directors Melissa Bethell, Bertrand Bodson, Thierry Garnier, Stewart Gilliland, Caroline Silver, and Karen Whitworth.
Tesco operates under a one-share-one-vote principle, with major institutional investors engaging through stewardship and voting rather than board seats. The board emphasises independent non-executive directors with retail, consumer, finance and technology experience.
Tesco Today — Size and Scale
Tesco’s net sales break down by activity as follows: distribution in the United Kingdom and Ireland accounts for 93.8% of the business through 4,001 stores. The group also offers telephony services through Tesco Mobile. Distribution in Central Europe accounts for 6.2%, with 561 stores located in Hungary, the Czech Republic and Slovakia.
Tesco’s adjusted operating profit for 2024/25 rose by 10.6% to £3.13 billion, demonstrating resilience amidst inflationary pressures.
My Take on Tesco
Tesco’s story is genuinely remarkable. A man with £30, a market stall, and a motto of “pile it high and sell it cheap” built what became one of the world’s most recognised retail brands. What’s interesting about Tesco’s ownership today is that no single person or family controls it — it belongs, in a real sense, to millions of pension funds and investment portfolios around the world. That’s a long way from Jack Cohen’s stall in Hackney. The challenge now for CEO Ken Murphy is keeping Tesco relevant against the relentless pressure of discounters like Aldi and Lidl, while investing in technology, sustainability and loyalty. Tesco’s market share increasing by 0.67% to 28.3% in 2024/25 — the highest in nine years — suggests the foundation is strong. Whether that momentum continues remains the big question.
