Aldi vs Lidl: Which Is Cheaper in the UK? (2026)

Last updated: 21 October 2026. Price comparison: September 2026; loyalty details checked in October 2026.

Aldi vs Lidl: which is cheaper? Aldi narrowly won the latest completed monthly Which? comparison available when I checked. But a £2 gap on a 93-item list does not mean Aldi will beat Lidl on your shopping list—or justify an extra journey.

I would use that result as a starting point, then compare the food your household actually buys, the Lidl Plus offers you can use and the cost of reaching each shop. This is a researched comparison, not a claim that I have carried out a new Aldi-versus-Lidl taste test.

Start with the answer below, then use my Grocery Savings Calculator to test your own numbers.

Aldi vs Lidl: the quick answer

Choose Aldi as the initial price benchmark; choose the shop that gives your household the lower usable-food cost. Lidl can still be better value if its relevant offers, location or product selection outweigh the small published basket difference.

There is no evidence here that one chain has better-quality food in every category. Nor does one monthly price comparison establish a permanent winner.

Which is cheaper, Aldi or Lidl? The checked prices

In Which?’s September 2026 comparison, the average cost of its 93-item list was:

What this measures: Which? averages prices across the month and totals those averages. Its methodology includes applicable loyalty prices but excludes personalised rewards, points and multibuys. The selected items can change between months, so do not interpret changes in basket totals as a like-for-like inflation measure.

The £2 difference is about 1.24% of the Lidl Plus total: £2 ÷ £161.48 × 100. That is my calculation, not a separate Which? statistic. It describes this basket, not a promised percentage saving on your spending.

I would not multiply that monthly research gap by 52 and call it a guaranteed annual saving. Your weekly basket, quantities, offers and prices will differ. Use receipts instead.

7 ways to choose the better-value shop

1. Compare your usual basket

Write down ten to fifteen products you buy regularly, including quantities and the versions your household accepts. Milk, bread, rice, eggs, washing-up liquid and fruit are useful starting points if they are on your normal list.

Keep like-for-like comparisons sensible. Standard own-brand pasta is not directly equivalent to a premium filled pasta. Match pack size, product type and any dietary requirements before deciding which is cheaper.

Record the branch, date, pack size, shelf price and any discount you actually qualify for. If an item is unavailable, mark it as missing rather than substituting something much more expensive without recording the change.

For a gradual approach, use my supermarket downshift challenge guide. Test a few swaps before changing everything.

2. Compare unit prices

The cheaper packet is not necessarily the cheaper quantity. Use a common unit such as price per kilogram, litre or item.

Illustration only—not live Aldi or Lidl prices: a 500g pack at £1.50 costs £3 per kg. A 750g pack at £2.10 costs £2.80 per kg. The larger pack has the lower unit price, but it only helps if you will use it.

If you need just 500g and the rest will be wasted, the £1.50 purchase leaves more money in your budget today. Value depends on usable quantity as well as the shelf label.

3. Use Lidl Plus without chasing rewards

Lidl’s official GB page confirms that Lidl Plus Points replaced Coupon Plus from 5 May 2026. The standard earn rate is one point per £1 of qualifying spending, rounded up to the nearest pound. Check the current terms for exclusions and redemption conditions.

A point earned is not automatically a penny saved. Look at the reward you can redeem, whether you want it and when it expires. Separate a discount on today’s purchase from a possible reward on a future visit.

Check whether relevant coupons need activating before payment and whether your chosen products qualify. Do not add unwanted items just to reach a target or earn a reward.

The Which? Lidl Plus basket is not a complete valuation of your personal app benefits. Equally, an excellent coupon on one product does not prove Lidl wins your whole shop. My supermarket loyalty apps guide covers the wider comparison.

4. Judge quality product by product

Questions such as “Aldi or Lidl: which has better quality?” appear in shopper discussions because preferences differ. One household’s favourite bread may be another household’s rejected sandwich.

Compare taste, ingredients, portion size, preparation time and whether the product gets eaten. Try one replacement at a time so you know which swap worked. Avoid buying a large supply before checking whether it suits your family.

A supermarket-wide winner cannot be established from a few positive or negative comments. Treat shopper quality discussions as sources of questions to investigate, not controlled product tests or evidence that your branch has the same issues.

For dietary needs, read the current packaging every time you change product. Similar-looking products can have different ingredients. Lidl’s bakery page also provides allergen information for its loose bakery range.

5. Check freshness and what gets wasted

“Which shop has better fruit and veg?” needs a local, practical answer. Check the condition of the produce you are buying, how soon you will use it and whether the quantity fits the meals planned.

Do not label all produce from either chain poor-quality because of one disappointing purchase or a forum comment. Storage after purchase and the time before use also affect the outcome.

For your comparison, record what was thrown away and why. A lower receipt total is less useful if part of the food never becomes a meal. Smaller packs, loose items or frozen alternatives may suit your routine better.

My food-rescue and yellow-sticker guide explains another way to assess surplus food without assuming every reduced item is right for you.

6. Add travel and top-up costs

A small shelf-price saving can disappear if you make another trip or need a second shop for missing items. Include transport and the extra products picked up during that top-up visit.

Hypothetical example: the groceries on your list cost £60 at one shop and £62 at another. If reaching the first shop costs £3 extra, its combined cost is £63. The nearer £62 shop is £1 cheaper overall, before considering your time.

Those are invented figures to show the calculation, not Aldi or Lidl quotations. Your extra journey might cost nothing if the shop is already on your route. Use your circumstances.

Use the Fuel & Commute Cost Calculator for an estimate of driving costs. Keep any parking charge or bus fare separate where relevant.

7. Count the middle aisle separately

Aldi Specialbuys and the Middle of Lidl can add useful household purchases to a trip. They can also make a low-cost food shop expensive if you buy things you had not planned to replace.

Keep non-food items separate in your comparison. A receipt containing a saucepan cannot fairly be compared with a food-only receipt from the other shop.

Put unplanned purchases on a separate list and decide later. Check the specification, total price and whether you already own something suitable. A supermarket setting does not make every household product the best-value option.

My guide to checking discount claims gives a useful price-comparison process outside the food aisle too.

Lidl Plus vs Tesco Clubcard: does loyalty change the answer?

It can change your own result. But compare the final basket before comparing points. A member price at Tesco is worth checking against both Aldi’s shelf price and the Lidl price available to you.

Tesco confirms that 150 Clubcard points convert to £1.50 in vouchers, with up to twice the voucher value at Reward Partners, subject to their terms. That is not a blanket cash discount on all groceries.

Do not assume Lidl only rewards a future visit while Tesco only discounts today’s shop: member offers and later rewards are separate features. Check each relevant offer rather than choosing from the logo alone.

If you also use Morrisons, see my Morrisons More vs Tesco Clubcard comparison. For receipt rewards, check the eligible products and stores in my receipt cashback apps guide; do not assume every app accepts every supermarket.

What I would do first

1. Choose a normal shopping list. Use comparable quantities and exclude a party, bulk restock or other unusual week.
2. Check both local options. Record prices, relevant member discounts, travel and missing items. You do not need to buy two full shops to compare shelf labels.
3. Keep the swaps that work. Review taste, waste and the total spent before making one supermarket your default.

Then enter a realistic weekly difference in the Grocery Savings Calculator. If your own measured saving were £3 a week, £3 × 52 would be £156 a year only if that saving continued for 52 weeks. That is an illustration, not a forecast.
