High-end department store chain John Lewis & Partners has been a mainstay in the UK since its foundation in 1864. The company operates in the UK and also has concessions in Ireland. It is a part of the employee-owned cooperative company known as the John Lewis Partnership. In London's Oxford Street, the first John Lewis store was established. Since then, the company has grown to include 35 locations around Great Britain. The brand's long-standing "Never Knowingly Undersold" vow, which matches lower pricing provided by national high street competitors, demonstrates its dedication to quality and consumer pleasure.

The firm sells everyday items and founded the biggest co-operative in the United Kingdom, among other various offers. The business was founded in 1929 by Spedan Lewis, the founder's son. The company has a long history; in 2016, it opened its first concession in Australia and its first in Ireland, both in Dublin Arnott's stores. The Oxford Street store's reputation for excellence was furthered in 2008 when Queen Elizabeth II granted it a Royal Warrant as "suppliers of haberdashery and household goods”.

John Lewis & Partners is a cultural institution as well as a well-known retailer. Its yearly Christmas television advertisement, which was originally released in 2007, has been viewed as a sign that the countdown to Christmas has started in British culture. John Lewis & Partners is nevertheless successful despite the difficulties facing the retail sector, a testament to the power of its brand and the devotion of its patrons.
