Waitrose is on average 58.4% dearer than Aldi
ⓘ
If we had drawn a different but equally fair set of basket products, the figure would fall inside this range 95 times out of 100. Products that share a shop product are drawn together, so a shared price never counts twice.Read the other way: Aldi is on average 36.9% cheaper than Waitrose (a percentage changes with the shop you start from).
Based on 282 products in the Price Monitor's basket that both shops sell, matched to 197 different pairs of shop products. Below are 75 of those pairs, spread across categories by household spending. For the full list, email research@allsupers.co.uk.
Waitrose was dearer on 273, cheaper on 9 and the same price on 0 of these 282 products. These counts show direction only; the average above also weighs how large each difference is and each category's share of spending.
Each row starts from a product in our basket. At each shop we take the most similar own-label product, confirmed by our automated matching check. One shop product can be the closest match for several basket products, so it can appear in more than one row.
Most Waitrose own-label meat is free range, slower reared or organic, which our matching check treats as a different product from standard meat. Only a few Waitrose meat products count here, and they carry meat's full share of spending.
How we compare prices
We compare the price per kilo, per litre or per item, so pack sizes do not distort the result. Items sold by the piece are only compared with a similar number of pieces. Own-label means each shop's own brands, whatever their name; premium ranges rarely pass our matching check, so these are mostly standard lines. Prices as of 30 September 2026; where a cheaper promotion was running, we use that price.
How the figure is worked out
For each spending category we average the price differences of the products both shops sell, then combine the categories by their share of household spending. The ranking on the Price Monitor page compares all shops at once, through every other shop as well, so it can differ from this two-shop figure; for these two shops the ranking gives Waitrose 54.9% dearer. Categories with fewer than 10 products both shops sell: meat: 7 products, 18% of the weight, non-alcoholic beverages: 1 product, 8% of the weight, household goods: 4 products, 4% of the weight, oils and fats: 3 products, 3% of the weight. They count at their full share of household spending, like every category, so they can move the figure more than their few products suggest.
