Aldi was the cheapest supermarket in August, Which? finds
Aldi has beaten rival Lidl to be named as the cheapest supermarket in August, Which? research has found.
The consumer champion’s monthly analysis involves comparing the average prices of a shop consisting of popular groceries at eight of the UK’s biggest supermarkets.
The cheapest supermarket for a shopping list of 62 items was Aldi, where the groceries cost £110.58 on average across the month.
Fellow discounter Lidl was just behind Aldi in August costing £1.30 more with Lidl Plus at £111.88 on average, and £112.17 without.
Waitrose was the most expensive supermarket this month, totalling £140.89 - a difference of £30.31 compared to Aldi - 27 per cent more.
The list of 62 items included a number of both branded and own-brand items, such as Heinz baked beans, Hovis bread, milk and butter.
The analysis includes special offer prices and loyalty prices where applicable, but not multi buys.
Tesco Clubcard members would have paid £123.13 - while without a Clubcard, the Tesco shop cost just 49 pence more at £123.62.
For those using a Sainsbury’s Nectar card, August’s shopping list of items cost £123.75. Without a Nectar card, the same items at Sainsbury’s cost £129.63.
While Morrisons and Waitrose do also operate two-tier pricing, their schemes are currently on a smaller scale and this month, no items on Which?’s list were available at a lower price to all members of these schemes.
This latest pricing analysis from Which? demonstrates that shoppers can make considerable savings on their groceries depending on where they buy their food.
Ele Clark, Senior Which? Money and Shopping 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 that many people are choosing discounters to cut costs. By switching supermarkets, consumers could save 22%, highlighting the advantages of shopping around."

Notes to editors:
Research
Each month Which? compares how much supermarkets charge for a selection of groceries (this month 62 items). The data is taken, based on availability across supermarkets that month, from our longer list of around 200 items. This list is made up of some of the UK’s most popular groceries, based on industry data on sales value and availability. We include special offers and two-tier loyalty discounts where they apply but not multibuys. We can’t include personalised loyalty discounts because these vary from shopper to shopper.
Because the main list of around 200 groceries remains unchanged from month to month (other than being refreshed occasionally to reflect consumer shopping habits), Which? never shares the full list of products with retailers as we want to avoid any attempt to skew the results. We do not want supermarkets to compete with one another to lower prices only on the items they know they will be judged on. Instead we want retailers to work to make groceries affordable across the depth and breadth of their available lines.
Full table of results for August (based on 62 items):
| Retailer | Average price |
| Aldi | £110.58 |
Lidl (with Lidl Plus) | £111.88 |
Lidl (without Lidl Plus) | £112.17 |
| Asda | £121.85 |
| Tesco (with Clubcard) | £123.13 |
| Tesco (without Clubcard) | £123.62 |
| Sainsbury's (with Nectar) | £123.75 |
Which? looked at loyalty pricing for Lidl, Tesco, Sainsbury's, Morrisons and Waitrose, but only Lidl, Tesco and Sainsbury's had items on our shopping list with a loyalty price this month. Asda doesn't have two-tier loyalty pricing. Its loyalty scheme is based on points and personalised rewards, not lower prices for every scheme member.
As there are restrictions on who can access loyalty prices, Which? will only award a cheapest supermarket endorsement to the retailer with the lowest prices that are available to all consumers.
