The cheapest supermarket in the UK has been revealed, with Aldi topping the list for the 11th consecutive month.

Consumer champion Which? found Aldi to be the cheapest supermarket for a basket of 93 items, beating out rival chain Lidl.

Even when loyalty card discounts were applied to rivals including Tesco, Sainsbury's and Morrisons, Aldi was still found to be the most affordable.

A basket of 93 popular everyday items was found to cost £159.48 at Aldi.

The most expensive supermarket chain was Waitrose, where a basket cost £223.38 - £63.90 more than Aldi.

The basket of items consisted of a mixture of own-brand and branded products, including essentials like milk, cheese and Hovis bread.

The exact same items were used at each supermarket chain.

Julie Ashfield, Chief Commercial Officer at Aldi UK, said: "Families shouldn't have to make sacrifices to the activities, treats, or hobbies they enjoy just because everyday household budgets are under pressure.

The latest Which? data clearly demonstrates that shoppers can make substantial, ongoing savings simply by changing where they do their weekly shop.

“As the price gap between Aldi and traditional supermarkets continues to grow, that’s extra cash staying directly in customer pockets for days out, family treats, or saving towards Christmas.

Shoppers don't need to change their lifestyle to save money – they just need to change their supermarket."

Reena Sewraz, Which? Retail Editor, said: “With energy bills a major concern as the cold weather approaches, many households will be looking for ways to trim the cost of their food shop.

"A £60 mark-up on everyday groceries is a steep price to pay for store loyalty.

"September’s analysis proves once again that the discounters are the place to go to save - and when the cost gap is that wide, switching where you shop remains the quickest way to cut your grocery bill.”
