Aldi named UK’s cheapest supermarket once again
Aldi has once again been named as the UK’s cheapest supermarket.
Published: 9 January 2026
Consumer group Which? compared the prices of 68 popular grocery items and found that its shopping basket cost just £123.60 at Aldi.
That’s slightly cheaper than the £123.70 paid at Lidl by both Lidl Plus members and non-members.
Asda came next in the list, with the shopping basket costing £134.89, while Tesco (with the loyalty discount) rounded out the top five at £135.84.
They were followed by:
- Tesco (without the loyalty discount) - £139.12
- Morrisons (including loyalty discount) - £140.03
- Morrisons - £140.20
- Sainsbury's (including loyalty discount) - £141.45
- Sainsbury's - £143.74
- Ocado - £155.23
“While Lidl continues to provide strong competition among the discounters and is still a great option for those looking to save on their shopping, Aldi was cheapest in most months and offered the lowest prices overall,” said Reena Sewraz, retail editor at Which?
“Our analysis also shows that Asda remains a strong choice for shoppers looking for a bigger range of branded goods at lower prices.”
What if I’m doing a bigger shop?
Which? also compared the prices of a bigger trolley shop consisting of 180 items, including branded products.
These didn’t include Aldi and Lidl, as they have a smaller range of products than their competitors.
Asda came out on top, with the contents of the trolley costing £450.82.
This was followed by:
- Tesco (including loyalty discount) - £462.00
- Morrisons (including loyalty discount) - £466.04
- Morrisons - £467.46
- Sainsbury's (including loyalty discount) - £468.61
- Tesco - £493.53
- Ocado - £498.19
- Sainsbury's - £501.89
Waitrose was the most expensive supermarket in both categories, with a basket costing £170.46 on average and a trolley-load costing £529.17.
Shop around to save money
“With food bills still a major concern for many households, it really does pay to shop around,” said Ms Sewraz.
“Choosing one supermarket over another could save shoppers hundreds of pounds over the course of a year.”
