Aldi has lost its title as the UK's cheapest supermarket for the first time in nearly two years, with rival Lidl taking the top spot, according to a price analysis by consumer group Which?.
The analysis looked at an average basket of 76 grocery products across July, including both popular brands and own-brands. Lidl's total price was £128 with a loyalty card and £128.40 without, while Aldi came in at £129.25, a difference of less than £1.
Both discount supermarkets were around £17 cheaper than Tesco and £40 cheaper than Waitrose, which was the most expensive at £170.91. Tesco with a loyalty card was cheaper than Sainsbury's with a loyalty card, while Morrisons failed to beat any competitors regardless of loyalty card use.
In a separate analysis of 192 branded products, Lidl and Aldi were excluded due to not stocking all items. Asda came out cheapest at £474.12, with Waitrose 14% higher at £538.33.
Which? retail editor Reena Sewraz said: 'Households are still contending with high food prices but our analysis shows it pays to shop around. Simply choosing one supermarket over another could save you 25 per cent.'
