Cheapest Supermarket in the UK Right Now (2026)

The “cheapest supermarket” crown changes hands more often than people think. Aldi and Lidl have traded the top spot for years, Asda occasionally undercuts both on branded goods, and Tesco’s Clubcard prices have rewritten the rules for loyalty pricing. I’ve shopped at all of them extensively — currently I’m an Aldi regular with a Lidl bakery habit — and the honest answer depends on what you buy. Here’s the real state of play. Here’s who’s actually cheapest right now, and the strategies that matter more than the store you choose.

The Cheapest Supermarket Right Now: The Short Answer

For a typical basket of everyday groceries, Aldi and Lidl remain the cheapest overall, usually within pennies of each other. Which one wins in a given month depends on the specific basket — industry comparisons (including the regular Which? basket surveys) have them swapping first and second place all year. Asda typically comes third, Tesco and Sainsbury’s sit in the middle (much cheaper with Clubcard/Nectar prices than without), Morrisons follows, and Ocado, Waitrose and M&S bring up the rear on price.

How the Big Players Compare

• Aldi: Consistently cheapest or joint-cheapest on own-label basics. Smaller range, but what they stock is good quality — their Specially Selected range embarrasses some premium brands. The middle aisle is a dangerous place for your wallet, though.
• Lidl: Neck-and-neck with Aldi on price, with a better bakery (those croissants) and a stronger continental range. Lidl Plus app gives weekly coupons that genuinely add up.
• Asda: Often cheapest of the “big four” on branded items and strong on rollback deals. The George clothing and home range is a bonus.
• Tesco: Without Clubcard, mid-priced. With Clubcard Prices, frequently matches or beats Asda on hundreds of lines. If you shop Tesco, the free Clubcard is non-negotiable — not having one is leaving money on the table.
• Sainsbury’s: Similar story with Nectar Prices. Good quality own-label, especially the Taste the Difference range when discounted.
• Morrisons: Strong on fresh meat, fish and Market Street counters; loyalty scheme (More Card) helps but rarely wins on headline price.
• Iceland: Underrated for frozen food — often the cheapest way to buy veg, fish and ready meals, and the free delivery over £40–£45 thresholds is handy.

The Real Saving Isn’t the Store — It’s the Strategy

Here’s my honest opinion after years of tracking this: switching supermarkets saves maybe 5–10%, but changing how you shop saves 20–30%. The store matters less than the habits:

1. Always use the loyalty card. Clubcard, Nectar, Lidl Plus, More Card — they’re all free, and the discounts are now baked into pricing. Shopping without them is a self-imposed tax.
2. Buy own-label. The price gap between branded and own-label on basics like pasta, tinned tomatoes and oats is enormous, and blind taste tests routinely fail to tell them apart.
3. Shop the reduced section. Yellow-sticker hunting at the right time (evenings, especially) can halve your bill. Freeze what you won’t eat today.
4. Meal plan. The single biggest grocery saving most households can make. Our guide on meal planning to save money walks through it.
5. Check unit prices, not headline prices. The shelf-edge price per 100g/kg tells the truth; “2 for £5” deals often don’t.
6. Don’t shop hungry. Cliché because it’s true.

Online vs In-Store

Online delivery (£2–£7 per slot, or ~£8–£12/month for delivery passes) can actually save money by killing impulse buys — you can’t be seduced by the bakery smell through a screen. But the discounters’ online presence is limited: Aldi’s click-and-collect is patchy and Lidl has no full online shop, so committed bargain hunters still go in person. For a full breakdown of what households spend, see how much a weekly shop costs for two.

What About Quality?

The old snobbery about Aldi and Lidl is well past its sell-by date. Both regularly win blind taste tests and Which? surveys against premium rivals. The real quality gap in UK supermarkets isn’t between discounters and the big four — it’s between fresh and processed, whatever the store. Buy fresh, cook simply, and the store logo on the bag barely matters.

Loyalty Schemes: The New Price War

The most significant shift in UK grocery pricing in recent years isn’t Aldi vs Lidl — it’s the loyalty-price revolution. Tesco’s Clubcard Prices and Sainsbury’s Nectar Prices now discount hundreds of products by 20–50% for members, effectively creating two-tier pricing. The result: a Tesco shop with Clubcard is a different (much cheaper) shop than without.

My take: the schemes are free, the discounts are real, and refusing to use one on principle is an expensive stance. But be smart — loyalty prices are designed to lock you into one store. The winning move is holding all the loyalty cards (they’re free) and shopping wherever the week’s best prices are, not defaulting to one store out of habit. The MoneySavingExpert supermarket guides track which loyalty deals are genuinely good versus inflated “was” prices.

The Discounters’ Weak Spots (When to Shop Elsewhere)

Aldi and Lidl win on price, but they’re not perfect for everything:

• Range: ~2,000 products vs ~30,000 at Tesco. If you cook varied cuisines, you’ll supplement elsewhere — try world-food shops for spices, lentils and rice at half the price.
• Brands: if you’re loyal to specific brands (baby formula, pet food, toiletries), Asda or Tesco with loyalty prices often beat the discounters.
• Online: neither discounter does proper online grocery delivery — if you need delivery, Tesco/Sainsbury’s/Iceland win by default.
• Fresh meat/fish counters: Morrisons’ Market Street is genuinely excellent and competitively priced for quality.
• Frozen: Iceland beats everyone on frozen range and often on price — the “shop frozen” strategy deserves more respect.

The optimal strategy for most households: discounters for the core shop, supplemented by loyalty-priced branded items at Tesco/Sainsbury’s, with Iceland for frozen. It sounds like effort, but two shops a month at different stores (one big discounter shop, one top-up) captures most of the saving.

Timing Your Shop

Yellow-sticker reductions follow rhythms: most stores mark down fresh items in the final 1–2 hours before closing, with the deepest cuts (75–90% off) nearest closing time. Sunday evenings and weekday evenings are prime. Build a relationship with the reduced section and plan flexible meals around it — our meal planning guide has a “flex meal” slot designed exactly for this. And apps like Too Good To Go (£3–£5 surprise bags from shops and restaurants) turn end-of-day surplus into genuine bargains.

The Practical Takeaway

Right now, Aldi and Lidl are the cheapest UK supermarkets for a standard basket, with Asda close behind and Tesco/Sainsbury’s competitive if you use their loyalty prices. But the bigger win is behavioural: loyalty cards, own-label swaps, yellow stickers and a weekly meal plan will save you more than any store switch. Pick the cheapest convenient store, then fix the habits — that’s where the real money is. And if you’re building a budget from scratch, our emergency fund guide is the best next read.
