How Did John Lewis’ History Shape its Reputation?
John Lewis is one of the most well-known and respected department stores in the United Kingdom. Founded in 1864, the company has grown into a retail giant, offering products across multiple categories, including fashion, homeware, electronics, beauty, and furniture. With a strong focus on customer trust and quality, John Lewis built a reputation that set it apart from competitors.
A significant component of John Lewis’s identity was its long-standing pricing promise: “Never Knowingly Undersold” (NKU). Introduced in 1925, NKU assured customers that John Lewis would match any lower price found at a competing high street retailer. However, as the retail industry evolved—particularly with the rise of e-commerce—maintaining this pledge became increasingly difficult. In 2022, the company made the difficult decision to discontinue NKU, citing the challenges of keeping up with dynamic online pricing models and the changing competitive landscape.
Despite stepping away from NKU, John Lewis recognized the need to maintain a strong pricing strategy to preserve its reputation and customer loyalty. In 2024, under the leadership of new management, the company sought to bring back the essence of NKU in a modernized form. The reintroduction of this policy is part of a broader strategy under the leadership of executive Peter Ruis to enhance customer trust and align with contemporary retail dynamics. Implementing this policy required a more sophisticated approach to pricing — one that could dynamically adjust to market changes while ensuring John Lewis remained the most competitive across all key product categories.
What Challenges Came With Dynamic Pricing at Scale?
John Lewis operates across dozens of categories and sells hundreds of thousands of products. Maintaining a competitive edge in such a vast and complex portfolio is an immense challenge. Unlike the traditional retail environment of the past, where pricing adjustments were relatively infrequent, today’s pricing landscape is highly dynamic. Competitors adjust prices frequently, sometimes multiple times a day, making manual tracking and updating of prices nearly impossible.
Before implementing a modern dynamic pricing solution, John Lewis found itself struggling to uphold its promise of competitive pricing. The company was only the most competitive for a subset of their categories, but not for its entire assortment. To truly bring back the spirit of Never Knowingly Undersold, John Lewis needed an automated, intelligent solution that could monitor, analyze, and adjust optimized pricing strategies in real time across its extensive product range.
