Source and evidence

The Grocer — Cadbury and Mars Wrigley shrink chocolate packs amid cocoa inflation (25 Feb 2025) thegrocer.co.uk

Source fetched 2026-10-20. All 33 The Grocer cases.

Sizes come from retail analyst Steve Dresser's Tesco shelf photos quoted by The Grocer (the 'new' 100g Twirl Bites format; the former 110g packs on the reduced-to-clear shelf). No prices given. Mondelēz confirmed it had shrunk packs.

Check the math in the calculator.

Against official inflation: ONS CPI (UK) “sugar, jam, honey, syrups, chocolate and confectionery” changed +9.5% (12 months to Feb 2025). The size cut alone raises the price per gram by +10.0% if the shelf price stayed the same (the source recorded no prices). Every case is compared the same way in the ShrinkRadar Index.

What the source says

“…Another photo posted by Dresser to X showed the former 110g formats of Cadbury Twirl Bites and Oreo Bites stocked on Tesco’s “reduced to clear” shelf.”
