Iceland is on average 6.2% cheaper than ASDA
ⓘ
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.Read the other way: ASDA is on average 6.7% dearer than Iceland (a percentage changes with the shop you start from).
Based on 261 products in the Price Monitor's basket that both shops sell, matched to 211 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.
Iceland was dearer on 183, cheaper on 68 and the same price on 10 of these 261 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.
Few shared products in bread and cereals, food products n.e.c., household goods, oils and fats; without them, this figure would be +14.7%.
Asda is shown but not ranked. Our own system failed to collect Asda's fruit and vegetables from 11 May to 6 October 2026, so those two categories are missing for Asda; the fault is ours, not Asda's. Asda's figures here cover the other categories.
Iceland is shown but not ranked: its own-label range has no products similar enough to compare in fish, personal care, or sugar and sweets. Iceland's figures here cover the other categories.
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 Iceland 9.6% dearer. Categories with fewer than 10 products both shops sell: bread and cereals: 1 product, 27% of the weight, food products n.e.c.: 2 products, 9% of the weight, household goods: 1 product, 6% of the weight, oils and fats: 2 products, 4% 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.
