Where the prices come from
Real UK prices, not guesses.
Each ingredient is costed from the Office for National Statistics' price quotes: the prices its collectors record in shops across the UK every month. We use the median price for each item (January 2026, the latest month the ONS has published grocery prices for). Packed food is rounded up to whole packs, the way you actually buy it; loose fruit and veg are costed by weight.
Budget supermarkets are often cheaper than the median, and convenience stores dearer, so treat the total as a guide. Cupboard basics like oil, salt, garlic and stock cubes are listed for you to check but aren't in the total.
