Lidl London vs Mercadona: Basket 35% Cheaper in UK

Lidl London vs Mercadona: Basic Basket 35% Cheaper

Is eating really more expensive in the United Kingdom than in Spain? A Spanish shopper living in London argues otherwise, documenting his claim with photos and a price table. Six basic products purchased at a Lidl in London totaled €3.56, compared to €5.38 for the closest equivalents at Mercadona. This represents a 35% difference in a sample including almond milk, carrots, cornflakes, macaroni, tomato sauce, and red pesto. Far from settling the debate, this finding sparked a two-thousand-day argument over what "cheaper" actually means.

Products Compared and Results

The list is short but specific. Almond milk at €0.96 versus €1.40; carrots per kilo at €0.55 versus €0.59; 500g cornflakes at €0.56 versus €0.87; 500g macaroni at €0.32 versus €0.59; basic tomato sauce at €0.55 versus €0.68; and red pesto at €0.62 versus €1.25. The author insists that Mercadona is the cheapest national supermarket chain according to his own spreadsheet comparing various retailers, noting that prices at the London Lidl were "considerably cheaper" than those at the Barcelona Lidl he visited months earlier.

He adds a detail that reinforces the paradox: a punnet of blueberries for one pound, more than double the cost in Spain, yet originating from Spain. In other words, the same product crosses the border and returns cheaper than it was sold at its source.

The Response: "That's Junk Food"

The majority reaction did not dispute the prices but rather the basket composition. Several participants labeled the chosen items as low-quality food, demanding a comparison with fruit, vegetables, fish, and meat. The author responded that carrots, pasta, cereals, or tomato sauce are staple goods in any shopping alucinación, challenging critics to define their own dietary standards.

The exchange escalated into personal insults, with cross-accusations of manipulation and lack of data. The discussion evolved into a power struggle over who has the right to define acceptable nutrition.

The Fish Counterexample: Sea Bass Triples in Price

The strongest rebuttal came via fresh fish. One participant compared sea bass fillets: approximately €7.80 per kilo at Mercadona versus €23.80 per kilo at Tesco, checked at the time of writing. That is triple the price, and these were not special varieties; according to the same check, they came from Turkish farms. The conclusion was that savings depend entirely on the product chosen, making generalizations based on a pantry basket misleading.

Some argue that fish is a staple and boasting about cheapness on an island surrounded by sea while ignoring fresh fish prices cherry-picks favorable data. Others counter that the compared basket consists of weekly household essentials, not luxuries.

Private Label, Quality, and Comparing Apples to Oranges

The third line of attack was methodological. Critics pointed out that comparing Mercadona with Lidl is not comparing like-for-like; the correct approach would be Lidl Spain vs Lidl UK, or Alcampo, to isolate the country effect. It was also noted that red pesto in one country may have different ingredients than in another, and almond milk may vary in nut content, invalidating direct comparison.

The author maintains that the sample is what it is and the photos exist, claiming almost all fruit and vegetables at the London supermarket were cheaper than in Spain. The dispute over true product equivalence remains unresolved.

The Factor Rarely Disputed: Wages and Savings Margin

Even among critics, there is agreement on one point: the capacity to save from a British or German salary is greater than from a Spanish one. The author himself formulates this at the end, seeing much more room for savings on a UK wage than a Spanish one. Europe's cheapest supermarkets are German (Lidl and Aldi), pushing the comparison toward income levels rather than just prices.

An anecdote rounds off the issue: a master's degree classmate bought private-label noodles for ten to fifteen pence, living on them for a month to spend the remainder on alcohol every night. Cheap, yes. Nutritious, debatable.

With these differentials, the grocery basket should be the definitive argument for emigrating. And yet, no one moves abroad because of the price of macaroni.
