Cheapest supermarket UK: best supermarket prices for February 2025 named by Which - beating Asda and Tesco

• Aldi remains the UK’s cheapest supermarket, with a basket of 100 essentials costing £182.64
• Loyalty schemes don’t match Aldi’s prices, with Tesco Clubcard and Sainsbury’s Nectar still costing shoppers significantly more
• Tesco and Sainsbury’s are scaling back their “Aldi Price Match” campaigns, removing hundreds of products from the scheme
• Asda has scrapped its price match initiative, instead focusing on its Rollback price campaign
• Experts say supermarkets are struggling to compete with Aldi’s low prices while maintaining profit margins

Consumer group Which? has named the UK's cheapest supermarket for essential shopping in February.

A basket of 100 essential items at Aldi cost £182.64 - beating all other major supermarkets, including Tesco (£212.54), Sainsbury’s (£225.20), and Waitrose (£245.79).

Even loyalty card discounts from Tesco Clubcard, Sainsbury’s Nectar, and Lidl Plus couldn’t match Aldi’s prices.

Aldi shoppers saved £22.67 compared to Tesco Clubcard prices and £30.82 compared to Sainsbury’s Nectar prices - offering significant savings week after week.

The news follows announcements that Tesco and Sainsbury’s are scaling back their “Aldi Price Match” campaigns, raising questions about their long-term commitment to competitive pricing.

Sainsbury’s is removing over 100 products from the scheme, including staples like granulated sugar and value bread, while Tesco has cut around 150 items.

Asda scrapped its own initiative in January, shifting its focus to the return of the Rollback price campaign.

Industry experts have said these changes reflect the challenge of consistently competing with Aldi’s low prices while maintaining profit margins.

Julie Ashfield, Chief Commercial Officer at Aldi UK, said: "While other supermarkets are finding it challenging to maintain their price match promises, Aldi remains dedicated to providing the lowest possible prices without compromising on quality.

“Our commitment to value is unwavering, and we believe that shoppers deserve consistent savings, not fleeting promotions or complex loyalty schemes."

How do the supermarkets compare?

Here’s how much a basket of 100 essential items cost at the UK’s major supermarkets in February 2025.

What’s interesting is the limited savings that supermarket loyalty and reward schemes off. For instance, shoppers using Morrisons’ More card only saw savings of £2.42 across 100 items - an average of just 0.02p per item.

Tesco’s Clubcard - arguably the most popular such scheme - fared slightly better, with savings of £7.23 across a basket of essentials - 0.07p per item.

But Sainsbury’s Nectar card was the best performing reward scheme in February, giving shoppers savings of £11.74. A whopping 0.12p per item!
