Survey finds that Lidl trumps Aldi as cheapest supermarket last year, while Waitrose is named the priciest.

The consumer watchdog, Which? tracked the price of 45 popular branded and own-label products in eight leading supermarkets for at least 100 days between January and December 2020. 

It calculated the average price of certain items, such as Hovis bread, Knorr stock cubes and free-range eggs, throughout the year and the total average cost of all 45 items in the trolley.

Lidl’s basket of groceries cost £42.67 on average, while Aldi came a close second, with its basket costing just 34p more at £43.01.

Trailing behind in third place was Asda, with its basket costing over £5 more at £48.71 on average. 

Shoppers paid most for the same basket of groceries at Waitrose, at a cost of £68.69 per basket – and £26.02 more than a similar shop at Lidl.

Ocado was the second most expensive supermarket in 2020, with its basket of goods costing £66.83 on average. Sainsbury’s was named third most expensive at £56.38 per basket.

Prices at Tesco and Morrisons were middle of the table at £53.30 and £53.61 respectively.

This is the first year that German supermarkets Lidl and Aldi were included in Which?’s annual research, which included own-label items as well as branded products.

There were huge price differences between own-label products at Waitrose and Lidl. For instance, Waitrose’s own-label six pack of very large free-range eggs cost customers £2.47 on average, while similar sized free-range eggs at Lidl were almost half the price at £1.27.

Natalie Hitchins, Head of Home Products and Services at Which?, said: “Many households have been under financial pressure due to the pandemic, so getting value for money on their weekly shop has become more important than ever.

“Our analysis shows that customers do not have to pay over the odds for their groceries.”

How to cut the cost of your groceries

If you’re looking to cut back on your food shop costs even further, you should:

  • set a budget for your weekly shop and stick to it
  • prepare a list of ingredients/essentials before you shop - don’t be tempted by promotional deals
  • shop around for the best deals – don’t be loyal to one supermarket
  • never shop when you’re hungry as you may end up buying more food than you need
  • sign up to supermarket loyalty cards, so you can save up points towards essential shopping or cash in for reward schemes
  • buy seasonal fruit and vegetables and avoid pricier pre-prepared products
  • google ‘supermarket deals’ to find the latest offers on money-saving blogs, apps and websites
