The retailer has seen sales rise 8.8% in the 12 weeks to 17 May and has overtaken Morrisons.  This growth underscores continued customer confidence in the discounter’s value-led proposition, solidifying its position as a destination for the weekly shop.

The achievement marks a major milestone in Lidl GB’s sustained expansion since opening its first store in 1994. With more than 3 in 5 households now shopping at Lidl, the discounter has secured over £661 million in switching gains5 from customers moving from competitors over the last year.

Ryan McDonnell, CEO of Lidl GB, said: “Becoming Great Britain’s fifth‑largest supermarket is a significant milestone and a clear indication of the momentum we have built. As customer expectations shift, households are looking for value they can rely on without compromising on quality, and we remain laser-focused on delivering exactly that.

“Achieving this is a testament to the dedication of our colleagues, whose hard work delivers for our customers every single day. As we move forward with our ambitious expansion plans, we’ll bring great value and quality products to even more communities across Great Britain.”

Lidl GB has maintained its position as Britain’s fastest-growing bricks-and-mortar retailer for 35 months. Driving this momentum is the discounter’s More to Value proposition.

Focused on great quality and freshness at consistently low prices, it is backed by its commitment to long-term sourcing and support for local communities, ensuring customers get trusted value without compromise.
