So, Which Supermarket Is Actually Cheapest in Scotland?
It's the single most-asked question about the weekly shop, and the honest answer hasn't changed much in months: Aldi and Lidl are consistently the two cheapest supermarkets available in Scotland, according to Which?'s independent monthly price tracking. The gap between them is usually pennies rather than pounds — but the gap between them and the traditional supermarkets is where the real savings are.
The Full Ranking (Which? Price Comparison)
Which? tracks the price of a comparable basket of everyday grocery items across eight major UK supermarkets every month. In the most recent survey, a basket of 89 items came to £161.56 at Aldi and £162.75 at Lidl — essentially neck and neck. From there the gap widens fast: Asda came in at £181.06, and Waitrose topped the list at £217.03 for the exact same basket. That's over £55 of difference for identical items, just based on which shop you walked into.
| Supermarket | Basket cost (89 items) |
|---|---|
| Aldi | £161.56 |
| Lidl | £162.75 |
| Asda | £181.06 |
| Waitrose | £217.03 |
Why the Discounters Keep Winning
Aldi and Lidl have topped or near-topped Which?'s ranking for the better part of two years running, and it comes down to a simple structural reason: both stock a smaller, mostly own-label range, which cuts out the cost of stocking dozens of competing brands. Independent taste tests consistently rate their own-label products — milk, butter, eggs, pasta, tinned goods — as equal to or better than branded equivalents at full-range supermarkets, at a noticeably lower price.
One practical catch for Scotland specifically: Aldi does not currently offer home delivery, so if you need your shop delivered rather than collected in person, this immediately narrows your cheapest options to Lidl (where available) or a discount-focused click-and-collect service.
Buying Branded Items? The Picture Changes
If your list includes specific branded products that Aldi and Lidl simply don't stock — think Heinz, Kellogg's, Hovis — the ranking shifts. For a larger 225-item basket including these brands, Tesco with a Clubcard recently took the top spot for the first time in over a year, narrowly ahead of Asda, with Morrisons in third. Without loyalty card prices applied, the same Tesco basket jumps by nearly £50 — a reminder that scanning your Clubcard or Nectar card at every visit isn't optional if you're shopping at a full-range supermarket.
Our Verdict for Scottish Shoppers
For the core weekly shop — fresh produce, dairy, pasta, tinned goods, cleaning products — Aldi or Lidl, whichever is nearer to you, remains the cheapest realistic option in Scotland. The most effective strategy for most households isn't picking one supermarket and staying loyal to it: it's shopping the discounters for everyday staples and value-range items, then making a separate, smaller trip to a full-range supermarket — loyalty card scanned every time — for the specific branded products you can't substitute.
