Nestlé KitKat Chunky Peanut Butter nutrition

One bar (42g)Ultra-processed (NOVA 4)3 allergensNPM Score (2018): 24, higher is less healthy

Figures from KitKat UK product page, collected by Boone. Free sugar estimated by Boone. Last checked 17 October 2026. Data checks are led by Murray Dare.

Per 100g figures from Ocado’s multipack label, which match KitKat’s per-bar figures. Free sugar leaves out an estimated 3g of lactose per 100g, worked out from the 60% chocolate on the label at the legal minimum of 14% milk solids, so the real amount of lactose is likely higher. Lactose is the sugar in milk and is not free sugar.
