Aldi vs Lidl: We Tracked a 50-Item Basket for a Month and the Result Surprised Us

Ask any Brit on a budget and you'll get a firm opinion: Aldi's cheaper. Or no — Lidl is. The debate has raged in group chats and Facebook bargain-hunting groups for years, usually based on vibes and one memorable shop rather than anything resembling evidence.

So we decided to settle it properly. For four weeks, we bought the same 50 staple items from both chains — everything from a loaf of wholemeal bread and a four-pint of semi-skimmed to washing-up liquid, tinned tomatoes, cheddar and a bag of frozen peas. Same list, same quantities, receipts filed every week. Here's what a month of honest shopping actually revealed.

The Headline Result: It's Genuinely, Boringly Close

Over the month, our Lidl basket came in around 1.8% cheaper than Aldi's overall — a gap of roughly £2.40 on a basket costing around £130. That's it. That's the war.

But averages hide more than they reveal. Week one went decisively to Aldi; week three swung the other way after a strong Lidl promotion on pasta and rice. If you're loyal to one store and never stray, you're likely losing pennies, not pounds. The real story is in the item-by-item breakdown.

Where Each Store Wins

Aldi's sweet spots: fresh meat and poultry were consistently a touch cheaper, and their own-label cleaning products undercut Lidl on nearly every visit. Their Famous Five meat offers are genuinely competitive rather than marketing theatre.

Lidl's strengths: bakery items, cheese and their surprisingly good own-label coffee and tea range. Our 500g block of mature cheddar was regularly 30–40p cheaper at Lidl, which adds up fast if you're a cheese household (aren't we all?).

Dead heats: eggs, milk, bread and bananas barely moved between the two all month. There's effectively a floor price on basics that neither discounter will break.

The Lidl Plus Factor Nobody Mentions

Here's where our neat little comparison got messier. Lidl Plus, the chain's loyalty app, hands out personalised coupons, a weekly 'money off' scratch-card style offer, and — crucially — a discount on a £10+ basket when you 'unlock' it via the app. Across our four weeks, those perks knocked an extra £6–£7 off our Lidl spend.

Aldi, famously, has no loyalty scheme at all. No Nectar-style points, no app-based discounts. Aldi's argument has always been that its prices are low for everyone, all the time — which is fair, but it doesn't change the fact that a Lidl shopper willing to scan a few coupons is getting a better effective price than the sticker comparison suggests.

The verdict on loyalty: if you'll happily spend two minutes a week tapping through an app, Lidl edges ahead. If loyalty schemes feel like a faff, the difference evaporates.

Specialbuys, Middle Aisles and the Trap We All Fall Into

We'd be lying if we said we stuck to the list perfectly. Both stores' middle aisles — Aldi's Specialbuys and Lidl's Middle of Lidl — are engineered to make you leave with a paddleboard, a heated airer, or a garden gnome you never knew you needed.

Our advice: treat these aisles as a separate budget entirely. Some genuine bargains appear (our heated clothes airer has paid for itself in tumble dryer savings), but if you're doing a price comparison shop, walk through fast and don't make eye contact with the lamp that looks like a mushroom.

Practical Takeaways for Your Weekly Shop

• Split your loyalty. There's no prize for monogamy here. Our cheapest month would've been shopping Aldi for meat and cleaning products, Lidl for cheese, coffee and bakery.
• Download Lidl Plus even if you're sceptical. The unlocked basket discount alone covered our price gap in two of the four weeks.
• Watch the multi-buys. Both stores occasionally price a single item lower than the multipack per unit. Check the shelf-edge per-unit price every time.
• Compare own-label to own-label. Brand items at either discounter are rarely the best value — the own-label ranges are where the savings live.

So, Who Actually Wins?

On raw shelf prices: it's a coin flip that changes weekly. Factor in the app: Lidl, narrowly. Factor in convenience, store layout and how much you like the own-label taste: that's the tiebreaker only your tastebuds can settle.

The genuinely savvy move isn't picking a side in the Aldi vs Lidl war — it's refusing to fight it at all. Check both, use the app where it pays, and keep the middle aisle on a strict leash. Your bank balance will thank you either way.
