Lidl has officially been named the cheapest UK supermarket in June, according to the latest Which? analysis.
The supermarket received the accolade after the service compared prices for a trolley of 78 items throughout June, including groceries and household essentials.
On average Lidl customers would have paid £72.02 for the 78 items, which included own-brand products such as pasta, olive oil and salad tomatoes, as well as branded goods.
At other supermarkets the same products would have cost up to £40 more, the research found - although Aldi in second place was only 21p more expensive.
Ryan McDonnell, Chief Commercial Officer at Lidl GB, said: "At Lidl, we simply won’t be beaten on price - so we’re delighted that Which?’s analysis proves that.
"We know that families across the country are continuing to feel the impact of COVID-19 on their finances, so now more than ever, we’re committed to offering the best quality and value to our customers."
Which? was unable to include Aldi and Lidl in its analysis in April and May as they don’t list all of their prices online and, due to lockdown, it was unable to send researchers into stores to check prices.
But in June, with lockdown restrictions beginning to ease, it was able to start checking prices in stores again.
A Which? spokesperson said: "Unsurprisingly, the discounters have returned to the top of the cheapest supermarkets league table this month.
"Lidl pipped Aldi to the post, with just 21 pence difference between the two.
"Asda was the cheapest ‘big four’ supermarket, with our trolley of items costing £80.15, while upmarket Waitrose was nearly £40 more expensive than the discounters at £111.77."
