Lidl lifts its UK grocery share to 8.6% while Aldi, Tesco, Sainsbury's and Asda each lose ground
Lidl held 8.6% of the UK grocery market in the 12 weeks to October, up from 8.2% a year ago, Worldpanel by Numerator figures show. Aldi, the larger German discounter, slipped from 10.6% to 10.5% over the same period, so the gain is Lidl's alone.

What happened
- Lidl's sales were 7.1% higher than a year earlier, driven by growth in fruit, vegetables and wine.
- Over the last 12 weeks, 54% of British households shopped at Lidl.
- Asda had the biggest fall among the grocers, from 11.8% to 11.5% of the market.
- Lidl said its loyalty prices were a key driver of a 10.8% revenue jump to 13bn pounds in the year to February.
Why it matters
- decision Aldi's position on loyalty pricing becomes a live decision. A second 12-week reading with Lidl up and Aldi down would turn the stance into a cost its leadership has to justify.
- exposure Asda and Morrisons are shrinking billion-pound debts under private equity owners while their share is falling or flat. A further loss would land on balance sheets still being repaired.
- capability Lidl plans 50 new stores in the next year. Later readings will therefore mix new capacity with shopper loyalty, and the data will have to separate the two before anyone can say what drives the gain.
Lidl's gain is 0.4 percentage points [18]. The four larger grocers the report names lost 0.6 points between them [15]. Tesco went from 27.9% to 27.8% [1] and Sainsbury's from 15.3% to 15.2% [2], so each moved 0.1 points. The shares are reported to one decimal place [5], and we would not read much into a 0.1-point move from a single 12-week window. The positional change is larger. Lidl's 8.6% is 0.3 points above Morrisons' 8.3% [4][16], and a year earlier it was 0.1 points below [16].
Aldi's result limits what the figures can support. It is the larger of the two German discounters, and its share fell over the 12 weeks in which Lidl's rose [13]. The evidence is about Lidl. The two chains differ on loyalty pricing: Aldi is the only UK supermarket that does not use it [12], and its chief executive, Giles Hurley, has said the chain is focused on growing volumes over headline sales [14]. Worldpanel's Fraser McKevitt said Lidl Plus "appears to be resonating, with Lidl reporting a 23 per cent increase in app users over the last year" [9]. We think loyalty pricing is a plausible part of the explanation. The article does not say whether the share figures are measured by value or volume, and nothing in it separates loyalty pricing from the other differences between the two chains.
The category evidence rests on one named analyst, and it concerns Lidl alone. Fraser McKevitt, head of retail and consumer insight at Worldpanel, told City AM: "Of the 38 grocery sectors we measure, Lidl is growing ahead of the market in 28. It's always the large sectors that really move the dial for a retailer's growth, and Lidl is performing well in fresh produce, alcohol, prepared foods, soft drinks and dairy." [7] That is about 74% of the sectors Worldpanel measures [19]. Fresh produce and prepared foods are two of the five sectors he names; alcohol, soft drinks and dairy are the other three [7].
Asda is where a company statement and the data diverge. A spokesperson said: "while the grocery market has slowed in recent weeks, we continue to narrow the gap to competitors." [21] On the Worldpanel numbers, Asda's gap to Tesco went from 16.1 points to 16.3, and its gap to Sainsbury's from 3.5 to 3.7 [17].
What to watch
- Worldpanel's next 12-week reading: whether Lidl stays above Morrisons' 8.3% and Aldi's share keeps falling in 0.1-point steps.
- Any change by Aldi to its no-loyalty-pricing position, or a statement from it on how its share looks by volume rather than value.
- Asda's share in the next reading, set against its spokesperson's claim that the gap to competitors is narrowing.
