UK’s cheapest supermarket crowned for 2025 out of Aldi and Lidl
The UK’s cheapest supermarket has been chosen by a low-cost retailer. Knowing which supermarket offers the best value for your regular purchase is always helpful given the current cost of living in the UK. In recent months, supermarket chains have been fighting head-on, and new research from consumer website Which? has revealed this year’s cheapest supermarket.
Aldi was deemed to be the cheapest supermarket of the year after comparing all supermarkets throughout 2024 and determining the average spend per trip. Lidl came in second place, not far behind Aldi, charging only £1.99 more on average per shop.
| Supermarket | Average price for 56 items |
| Aldi | £100.29 |
| Lidl with Lidl Plus | £101.48 |
| Lidl | £101.56 |
| Tesco with Clubcard | £111.22 |
| Sainsbury’s with Nectar | £112.13 |
| Tesco | £112.90 |
| Asda | £113.22 |
| Morrisons with More | £114.01 |
| Morrisons | £116.32 |
| Sainsbury’s | £116.70 |
| Ocado | £120.83 |
| Waitrose | £129.83 |
The results were based on a shopping list of 56 items, including essentials like milk, butter, and bread. For example, research from December showed that Aldi’s average total was £100.29, whereas its most expensive competitor, Waitrose, charged nearly £30 more for the same basket of goods.
Which conducted a second analysis? revealed that Asda was the only supermarket with larger shops for nine months of the year. But when loyalty schemes are taken into account, Tesco comes out as cheapest, followed by Sainsbury’s, saving up to £5.16 in groceries.
This research, based on a shopping list of 150 items, including the 56. Because they don’t consistently stock the same range of products as larger chains, Aldi and Lidl were excluded. Over the course of the year, shoppers could save nearly £400 on groceries by choosing cheaper supermarkets.
Does having a loyalty card make a big difference?
The typical savings from a loyalty program is between 17 and 25% of the original purchase. Supermarkets use loyalty programs to form lasting relationships with their customers, lowering prices for them in comparison to their rivals.
A typical example of loyalty pricing is a product’s “retail” price, with a lower price for customers with a loyalty card. Among the UK’s current loyalty card offering locations are:
- Tesco
- Asda
- Lidl
- Sainsbury’s
- Co-op
- Morrisons
- Iceland
- Waitrose
- Marks &, Spencer
A loyalty program is not currently offered by Aldi. But that hasn’t stopped it from achieving the top position for 12 straight months.
