Aldi vs Lidl: Which Is Cheaper in the UK? (2026)
Aldi vs Lidl on UK groceries: why the two discounters are so close, where each tends to win, what Lidl Plus changes, and how to price your own basket.
Reviewed by Uchirai Govere, co-founder of Store Search
Aldi and Lidl are the two German discounters that reshaped UK grocery shopping, and shoppers love to argue about which one is cheaper. They use almost the same playbook: small stores, a limited range, mostly own-label products and very little frills. That is exactly why the answer is so hard to pin down, and why a confident verdict from either camp should be treated with caution.
Quick answer
Aldi and Lidl are usually very close, and Aldi often has a slight edge on a basket of everyday staples. Lidl can come out ahead in a given month, especially when its Lidl Plus member prices apply to items you buy. The nearest branch and your own list matter more than the brand.
- Mostly everyday own-brand staples? Aldi, often by a small margin.
- Use Lidl Plus and buy the discounted items? Lidl can win.
- One is much closer? The nearer store usually wins once the trip is counted.
Why Aldi and Lidl are so alike
Both chains keep prices low in the same ways, so their shelf prices tend to follow each other:
- A limited range: fewer products than a supermarket, each bought in large volume
- Mostly own-label goods: less spent on brand marketing and listing fees
- Lean stores: simple layouts and low overheads per shop
- Direct competition: each watches the other, so staples rarely drift far apart
The result is that the two often sit within pennies of each other on the same kind of product. Independent trackers such as the Which? monthly cheapest supermarket comparison have framed the contest as a running Aldi versus Lidl race for exactly this reason, and Retail Gazette reported Lidl taking the top spot in one month, so the lead is not permanent.
Where each store usually has the edge
| What you buy | Tends to favour | Why |
|---|---|---|
| Everyday own-brand staples | Close, often Aldi | Both price aggressively |
| Items on a Lidl Plus offer | Lidl | Member-only prices on selected products |
| Promotions and fresh items | Varies | Depends on the branch and the week |
| Branded products | Neither reliably | Both stock few; a big supermarket may be cheaper |
Treat this as a pattern, not a rule. Prices change weekly and differ between branches, and a single promotion can flip a row for a few days.
Do the loyalty app and the drive change the answer?
Two things can move a close result. The first is the Lidl Plus app: it gives members lower prices on selected items, but those savings only count if you genuinely buy them. The second is distance. If Lidl is a short walk and Aldi needs a car journey, the fuel for the trip comes straight out of whatever Aldi saves you, and a small top-up shop will rarely justify a longer drive.
It is also common to find that the best answer is neither: if your list includes branded items, a larger supermarket on your usual route can be cheaper for the whole basket. See our guide to comparing grocery prices across stores for the method, and how Aldi stacks up against Walmart in the US for the same trade-offs in another market.
How to find the cheaper one for your own basket
- Write your real list: the items and pack sizes you buy most weeks, not a generic basket
- Compare live prices: select Aldi, Lidl and any other nearby UK stores in Store Search to see the cheapest store for the full basket and for each item
- Count the trip: use the travel cost calculator so distance and fuel are in the comparison
- Compare unit prices: pack sizes differ between the two, so compare per kilo or per litre
- Re-check now and then: the lead moves, so a quick comparison every few weeks keeps you honest
Store Search is free to start, with a monthly allowance of searches, and Premium removes the limit if you compare every week.
The bottom line
Aldi and Lidl are close enough that neither is the cheaper store for everyone. Aldi often has a small edge on everyday own-brand staples, Lidl can win a month or a basket when its member prices line up with your list, and the nearest branch frequently decides it. The reliable approach is to price your own list at both.

Frequently Asked Questions
- Is Aldi cheaper than Lidl in the UK?
- Often, but not always. Independent monthly price trackers such as Which? have repeatedly put Aldi and Lidl first and second, and the lead has changed hands between months. The gap on a typical basket is usually small, so the cheaper store for you depends on which products you buy and which branch is nearest.
- Is Lidl cheaper than Aldi with Lidl Plus?
- Lidl Plus gives members lower prices on selected items and personalised coupons, which can narrow the gap or tip a close month in Lidl's favour. It only helps if the discounted items are ones you actually buy, so check your own list rather than assuming the app makes Lidl the winner.
- Which is better value, Aldi or Lidl?
- Both are discounters built on a limited range, mostly own-label products and low overheads, so value is close. Aldi often has a slight edge on everyday own-brand grocery staples, while Lidl can win when its Lidl Plus member prices match your list. Compare the specific items you buy, not the brand reputation.
- Do Aldi and Lidl have the same prices?
- No. They are close on many staples because they compete directly and watch each other's prices, but individual items differ and change often. Promotions, regional pricing and stock differences mean the same product can be cheaper at either store in a given week.
- Are Aldi and Lidl cheaper than Tesco, Sainsbury's and Asda?
- On a typical basket of everyday groceries the discounters are usually cheaper than the big supermarkets, mainly because of their own-label focus. Branded goods are where the difference shrinks, and the large chains can undercut on loyalty-card deals or multi-buy offers, so a quick comparison on your own list is worth the time.
- How can I compare Aldi and Lidl prices for my own shopping list?
- Add your items to Store Search, select Aldi and Lidl (plus any other UK stores you can reach), and it compares live prices to show the cheapest store for the whole basket and for each item. Its travel cost calculator can also factor in the distance to each branch.
