Cheapest supermarket in the UK revealed: November 2025 update

Which supermarket is cheapest in November 2025? We compare Aldi, Lidl, Asda, Tesco, Sainsbury’s and more, using the latest monthly price checks from Which?.

One question comes up again and again in our supermarket savings community: “Where is the cheapest place to shop?”

The truth is, there isn’t a single answer.

We don’t have young kids, so we save on the additional costs, and no one in the family has allergies or intolerances to food. So, for me, and the stuff I buy, one supermarket can work out cheaper.

Just because the basket I buy one week is cheaper, the things you buy might work out more expensive.

Which is the cheapest supermarket in the UK?

To get some kind of fair comparison, consumer group Which? monitors supermarket prices each month. They build a basket of everyday items, look at the average price (including loyalty discounts), and compare the totals (* that must be a fun job *).

First, they made a shopping list of items they thought would be in a typical shopping basket. Their list included a mix of the store’s own products and branded items, such as fruit and veg, pasta sauces, baked beans and other everyday items.

They then worked out the average price (including loyalty scheme discounts) for each item across the month and compared it. It’s not meant to reflect your exact shop, but it’s still a useful way to see which supermarkets keep prices low on the things most of us buy.

So what did they find?

November 2025: the latest results

For November, Which? compared the cost of 70 everyday items.

Aldi takes first place again, with Lidl close behind.

At the opposite end, Waitrose is roughly £45 more than Aldi for the same type of basket.

These price gaps show how much money can be saved simply by choosing a different supermarket.

Here’s how the supermarkets ranked:

• Aldi: £121.22
• Lidl: £122.40 (or £122.35 with Lidl Plus)
• Asda: £133.59
• Tesco: £136.20 (or £133.65 with Clubcard)
• Morrisons: £137.40
• Sainsbury’s: £141.62 (or £137.77 with Nectar)
• Ocado: £154.37
• Waitrose: £166.79

This month’s figures show a clear gap between the discounters and the rest, even when loyalty discounts are included.

While these basket costs have up-to-date pricing, the average weekly food costs of what people actually spend can change depending on whether you buy for one, two or more people.

How November compares with last month

To help you see the trend, here’s how things changed from October to November:

• In October, Lidl was cheapest at £120.46, with Aldi just behind at £121.00.
• In November, Lidl rises to £122.40, while Aldi rises slightly to £121.22.
• Aldi moves back into the top spot.

The shifts are small, but they add up when you shop every week. Even a pound or two difference each week is £50 to £100 over a year.

How November compares with last year

It’s helpful to compare the year-on-year picture, but with a small warning:

Which?’s basket changes each month, so you can’t treat the older figures as pure inflation.

That said:

• In November 2024, Aldi’s basket cost £97.89, but this covered 55 items, not 70.
• The totals aren’t directly comparable, yet it still shows how stretched food budgets feel in 2025.

Even with discounts and loyalty schemes, a family shop is costing more than it did a year ago.

Cheapest supermarket month by month in 2025

Here’s how prices moved from one month to the next.

• November 2025 – Aldi – £121.22 (70 items)
• October 2025 – Lidl – £120.46 (70 items)
• September 2025 – Aldi – £122.77 (71 items)
• August 2025 – Aldi – £127.92 (75 items)
• July 2025 – Lidl – £128.40 (76 items)
• June 2025 – Aldi – £131.52 (79 items)
• May 2025 – Aldi – £135.48 (82 items)
• April 2025 – Aldi – £135.95 (79 items)
• March 2025 – Aldi – £133.73 (79 items)
• February 2025 – Aldi – £182.64 (100 items)
• January 2025 – Aldi – £185.83 (100 items)

You’ll notice the totals move around a fair bit through the year, mainly because the number of items in the basket changes from month to month.

And you may have spotted that January and February show higher totals because the basket was much larger at the start of the year (see that they had 100 items, but it’s since been changed to a lower amount, that’s why it looks like the totals dropped so fast).

It’s clear tracking monthly that Aldi has been cheapest for nine out of eleven months in 2025.

Prices rise and fall depending on the size of the basket, but Aldi and Lidl remain consistently in the lead

Aldi and Lidl’s value ranges continue to do the heavy lifting for families trying to reduce their weekly food bills.

Cheapest supermarket for a big branded shop

For the larger basket of 183 branded items, Aldi and Lidl don’t appear, as they don’t stock many of the branded products.

For November 2025, the results were:

• Asda: £455.52
• Tesco with Clubcard: £465.23
• Sainsbury’s with Nectar: £471.84
• Morrisons with More: £476.96
• Ocado: £493.35
• Waitrose: £522.91

Asda continues to lead the way for branded products, often by a decent margin.

Even with loyalty schemes, Tesco and Sainsbury’s don’t quite match Asda’s prices on the bigger trolley.

If your trolley leans heavily towards branded bits, Asda is still the most reliable supermarket for keeping the total down.

Do loyalty cards make a big difference?

Loyalty cards can help, but they rarely overturn the winners.

Here’s what changes:

• Lidl Plus takes a few pence off Lidl’s total.
• Tesco Clubcard brings Tesco closer to Asda.
• Nectar Prices helps cut Sainsbury’s total on many items.
• Morrisons More is included and lowers several lines.
• Aldi doesn’t have a loyalty scheme and still wins most months.

Loyalty schemes narrow the pricing gap, but the overall pattern stays the same.

Cheapest supermarkets over the years

Here’s a summary of how supermarket prices have shifted compared across recent years.

2024

• Aldi was the cheapest every month.
• Lidl stayed second throughout, normally £1–£2 behind Aldi.
• Waitrose was most expensive.
• Asda often won the larger branded trolley comparison.

• Waitrose remained highest priced.
• Asda again led the branded trolley tests.

2022

• Aldi was cheapest for seven months.
• Lidl topped the table for the first five months.
• Asda continued to win for branded goods.

• Lidl followed closely.
• Waitrose stayed highest.

2020

• Lidl finished cheapest overall, only 34p ahead of Aldi.
• Waitrose was around £26 more expensive than the discounters.

Earlier years

Before 2020, Which? didn’t include Aldi or Lidl in the comparison.

Sainsbury’s, Asda and Morrisons were the ones battling it out at the top.

How to use this information in your weekly shop

These supermarket rankings are useful, but they won’t match your exact trolley.

Every family buys different things. Some stick to value ranges, others mix in brands, and many people shop across more than one store.

Still, here are some handy pointers:

• Use Aldi or Lidl for the basics. The monthly data is consistent.
• Use Asda for branded items, especially for larger shops.
• Use loyalty offers, as they do cut the cost of key items.
• Mix and match where it makes sense.
• Compare the cost of the same item, as prices often jump between stores.
• Don’t forget yellow stickers, which can still beat all of the above if your timing is right.

You don’t need to change supermarkets forever. Even swapping one weekly shop a month can save a meaningful amount over the year.

Final thought

The headline result hasn’t changed much over the past few years. Aldi and Lidl continue to offer the lowest average prices for everyday items, while Asda generally wins on branded goods.

Food costs are still high, but knowing which supermarkets come out cheapest each month gives you one more tool to keep your budget steady.

If you want the very lowest totals, the numbers show that Aldi and Lidl remain the strongest choices for most households in 2025.

Will you change your habits for lower prices?

Does the study from Which? sway you to shop at another store because it’s “cheaper” than another supermarket in the UK?
