Aldi has once again secured its position as the UK’s most affordable supermarket according to the latest survey conducted by consumer experts at Which?. The monthly comparison of supermarket prices is aimed at helping shoppers identify the best value grocer in the market. In the March 2025 review, a shopping list comprising 79 items at Aldi amounted to an average of £133.73. This figure was found to be 67p cheaper than its closest rival, Lidl, which includes its Lidl Plus loyalty app. When factoring in Lidl Plus, the same shopping list came to £134.40, whereas without it, the cost was £134.43. Tesco followed closely behind as the next cheapest option for shoppers holding a Clubcard, with an average bill totaling £146.79, or £149.83 for those without the loyalty card, as reported by the Mirror. Asda ranked slightly higher, with an average bill of £147.09, making it more expensive than Tesco Clubcard holders but cheaper than those without a Clubcard. On the other end of the spectrum, Waitrose emerged as the most expensive supermarket for the 79-item list, with a total bill of £176.41, a significant £42.68 difference compared to Aldi.
In addition to the 79 items compared, Asda was found to offer the best value for a larger list of 203 grocery items. Asda tallied up to £498, surpassing Tesco with a Clubcard that amounted to £503.03. However, Waitrose maintained its position as the most expensive supermarket for the larger shop, with a total cost of £573.15, showing a variance of £75.15 compared to Asda. Reena Sewraz, the Retail Editor at Which?, noted the consistency of Aldi as the UK’s cheapest supermarket in the survey. Despite Aldi’s reigning status, Lidl has managed to narrow the gap between them. Sewraz highlighted Asda’s commendable performance, securing its place as the most affordable supermarket for a larger list of groceries. Sewraz underlined the impact of food inflation on shoppers, emphasizing the importance of cost-cutting measures, such as switching supermarkets to potentially save up to 24% on grocery bills.
The survey results for March 2025 revealed Aldi’s top ranking as the cheapest supermarket, with a total of £133.73 for the 79 items. Lidl closely followed, amounting to £134.40 for customers utilizing its Lidl Plus loyalty scheme. Moreover, the analysis highlighted Asda’s cost-effectiveness for the larger list of 203 items at £498, with Tesco emerging as the second most budget-friendly option at £503.03 for loyalty scheme users. The ongoing battle among supermarkets for affordability is paramount, given the current economic climate and the projected rise in food prices. The competition in the market benefits consumers by providing them with opportunities to save money through strategic shopping choices.
In conclusion, the survey conducted by Which? reaffirmed Aldi’s position as the UK’s cheapest supermarket for March 2025, with Lidl closely trailing behind. Asda’s dominance in affordability for a larger grocery list further underscores the varying dynamics in supermarket pricing. With shoppers continuing to navigate the challenges of rising prices, the findings advocate for exploring different supermarket options to capitalise on potential savings. The ongoing fluctuations in food prices highlight the importance of informed consumer decisions and strategic shopping practices to optimise budget allocation in the face of economic uncertainties.
