Waitrose is on average 3.6% dearer than Co-op
ⓘ
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. The range runs from cheaper to dearer, so these two shops are too close to call.Why two numbers? Across the 170 matched own-label basket items used here, Waitrose is 3.6% dearer than Co-op. The main ranking combines comparisons with other supermarkets within each category and gives Waitrose a 12.1% higher price level than Co-op; the ranking does not report a test between these two shops. It draws on more matched comparisons, involving different product selections. This page's direct comparison has fewer than 10 items in meat (2); sugar, jam, confectionery (2); personal care (2); fish (2); oils and fats (1), so a few products decide those categories and can move the figure. Your savings depend on what you buy. How we compare: allsupers.co.uk/research/methodology
Read the other way: Co-op is on average 3.4% cheaper than Waitrose (a percentage changes with the shop you start from).
Based on 170 products in the Price Monitor's basket that both shops sell, matched to 115 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 80, cheaper on 82 and the same price on 8 of these 170 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 31 August 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 12.1% dearer. Categories with fewer than 10 products both shops sell: meat: 2 products, 18% of the weight, sugar, jam, confectionery: 2 products, 6% of the weight, personal care: 2 products, 5% of the weight, fish: 2 products, 3% of the weight, oils and fats: 1 product, 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.
