vs
Iceland and Tesco are level with each other
ⓘ
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.Why two numbers? Across the 267 matched own-label basket items used here, Tesco is 6.2% cheaper than Iceland. The main ranking combines comparisons with other supermarkets within each category and gives Tesco a 5.9% lower price level than Iceland, a smaller difference that does not pass the ranking's statistical test. It draws on more matched comparisons, involving different product selections. This page's direct comparison has fewer than 10 items in vegetables (9); food products n.e.c. (1); fish (1); 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
Based on 267 products in the Price Monitor's basket that both shops sell, matched to 180 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.
Tesco was dearer on 83, cheaper on 149 and the same price on 35 of these 267 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.
Iceland's own-label range has no products similar enough to compare in personal care or sugar and sweets, so those two categories are missing for Iceland. In fish, other food, and oils and fats its figure rests on one product family each, and in household goods on two (both shopping bags). Its range is widened for the missing part.
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 Tesco 5.9% cheaper. Categories with fewer than 10 products both shops sell: vegetables: 9 products, 13% of the weight, food products n.e.c.: 1 product, 7% of the weight, fish: 1 product, 4% 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.
