Aldi has once again been named the cheapest supermarket in the UK for 2024, according to a comprehensive price comparison study by consumer website Which?. The study tracked grocery prices across eight major chains. The findings highlight significant savings achievable by shoppers who switch supermarkets.

The research, conducted throughout 2024, analyzed a standard shopping basket of 56 items. Aldi consistently offered the lowest average price, with a December total of £100.29. Lidl, a close competitor, came in second, with prices only slightly higher at £101.48 with their loyalty program, and £101.56 without.

Significantly, Aldi maintained its position as the most economical option for smaller shopping lists throughout the entire year. Shoppers using Aldi saved an average of £393 compared to those using Waitrose, the most expensive supermarket analyzed.

Waitrose, throughout 2024, remained the most expensive option, with a December average of £129.83 for the 56-item basket. The study also examined larger 150-item shopping lists, revealing Asda as the cheapest for nine months.

The difference in cost for bigger shopping baskets, particularly Asda's, was attributed to competitive pricing strategies employed by Tesco. Tesco's Clubcard prices proved cheaper than Asda's in three out of seven months, impacting Asda's overall cost position. Aldi and Lidl were excluded from the analysis of larger shopping baskets due to inventory limitations.

In conclusion, the analysis underscores the potential for substantial savings through careful supermarket choice. Consumers can use this data to inform their budgeting and purchasing decisions, maximizing value for their grocery expenditure.
