Consumer group Which? has named Aldi as the cheapest supermarket in the UK for September, with a basket of 59 items costing an average of £102.68. The discounter narrowly beat rival Lidl, where the same items cost £103.86 on average.
The analysis included both branded and own-brand products, such as Birds Eye peas, Hovis bread, milk and butter. Special offer prices and loyalty prices were taken into account, but multibuys were excluded.
At the other end of the scale, Waitrose was the most expensive supermarket, with an average total of £130.37 – £27.69 more than Aldi, a difference of 27 per cent.
Ele Clark, Which? retail editor, said: 'Our latest monthly analysis once again sees Aldi crowned as the UK’s cheapest supermarket. Given the ongoing strain of high food prices on household budgets, it's understandable many people are choosing discounters to cut costs.'
The research also found that Tesco Clubcard members would have paid £112.96 on average, while non-members paid £113.35. Sainsbury’s Nectar card holders paid £113.79, compared to £119.19 without.
In August, Aldi also topped the list with a basket of 62 items costing £110.58, with Lidl just behind at £111.88 with its Lidl Plus scheme.
