Nobody else is making the same commitment to everyday low prices – no clubs, no gimmicks, no tricks – just prices our customers can trust
Aldi UK sold a record £19 billion in 2025 and earned £432.9 million from it, an operating margin of 2.3%. It keeps prices low with no loyalty scheme, and plans to grow from 1,092 stores to 1,500, with £1.6 billion committed for 2026 and 2027. In August 2026 the competition regulator provisionally decided that Aldi no longer counts as a limited-range discounter.

Aldi competes on price alone, with no loyalty scheme, and keeps its margin thin to pay for it.

The other £97.7 goes back out on goods, people, and stores. Aldi UK’s commitment is everyday low prices with no clubs and no gimmicks.
When the rules on land deals for supermarkets were made in 2010, Aldi was left out as a limited assortment discounter, one that sells a significantly more limited range at a low price. In August 2026 the CMA provisionally found that it no longer qualifies.

Bardon in Leicestershire is 1.3 million square feet, automated, and built for nearly 7 million pallets a year. More than £500 million went into it, and fresh produce began there on 16 September 2026.
£900 million is planned for 2027, for 40 new stores and distribution centres, on top of more than £300 million in 2026 to extend and upgrade stores it already has.
Deliveroo riders will pick about 2,000 products from Aldi stores, starting on 6 October 2026 in eight towns.
Aldi UK’s sales rose 5% in 2025 while its operating profit held at about £433 million, so its margin thinned from 2.4% to 2.3%. We recommend a plan that names what it will give up to keep a promise, so that a flat profit line reads as the plan working.
The competition regulator’s provisional view of August 2026 is that Aldi’s stores are large and its range full enough to count as a large grocery retailer, and press reports of its evidence put the range at 4,000 to 5,000 products in most stores. We recommend re-reading, now and then, what made a strategy distinctive, because a rival, a regulator, or a shopper may already be treating it as something else.
Aldi UK will offer delivery through Deliveroo after a trial in eight towns, with riders picking from its existing stores, and its chief executive says this happens without changing how the stores operate. We recommend adding a channel by borrowing an existing strength and testing it in a few places first, so that a new way to sell does not need a new way to run.
