Aldi has declared it “won’t be beaten on price” after being named Britain’s cheapest supermarket in the second major price comparison this month.

According to analysis by The Grocer, the Big 4 are on average £8.32 (18 per cent) pricier than Aldi for a basket of 33 “everyday grocery items”.

Waitrose proved £23.24 (50 per cent) more expensive than the discounter.

The news comes after Aldi won the Which? crown for cheapest supermarket, pushing Lidl into second by a margin of 73p.

“Aldi won’t be beaten on price, and it’s great that this is recognised in an independent price comparison once again,” managing director of buying Julie Ashfield claimed.

“We want shoppers to know they can continue to count on us for the award-winning quality and unbeatable prices they can only find at Aldi.”

However, its Which? title reign has only lasted two months after being displaced by Lidl in August.

By contrast, Asda has a 22-month winning streak in the consumer group’s study of supermarkets which stock more branded products.
