A sourced, best-effort record of UK grocery changes.
Every item links to public sources: official data, press, trade reports or retailer pages.

Each item shows the unit price: per gram, ml, sheet, bag, bar or serving.
Charts compare the shelf price with an inflation-only benchmark.
The cost per gram, ml, sheet or bar after allowing for inflation. It captures price rises and smaller packs together.
Current prices are spot-checked online. In-store, loyalty and offer prices can differ.
Recipe, quality and portion concerns are kept separate from pack-size changes.
