Aldi has reclaimed its crown as the UK’s most affordable supermarket, outpacing its rivals including Lidl, Asda, and Tesco in the latest price comparison by consumer group Which?.

Aldi said that since the start of the year it has invested more than £300 million to help customers cut their grocery bills and has slashed prices on over 900 everyday items in the last few months.
Julie Ashfield, Chief Commercial Officer at Aldi UK, said: “Rising inflation has meant many shoppers are understandably more conscious about where they spend their money.
“That’s why we’ve already invested more than £300 million in price cuts this year, ensuring Aldi customers continue to benefit from the very best value.
“We know how important the lowest prices are to our customers, especially as they prepare for Christmas, and we continue to offer significant savings compared to the full-price supermarkets.”
Aldi has also just announced it plans to open 21 brand new stores within the next 13 weeks.
Some of the locations include Shoreditch in London, Durham in the North East, and Kirkintilloch in Scotland.
As of September, Aldi has raised its Store Assistant pay to a minimum of £13.02 per hour across the UK, and £14.35 within the M25, making it the highest-paying supermarket in the country.
For long-serving employees, wages can increase even further, with hourly rates rising to £13.95.
