"Are Skittles gluten free" gets asked almost as often as the vegan question, and the honest answer needs the same kind of care: it depends what you mean by gluten free.
What's actually in them
Standard UK Skittles don't list wheat, barley, rye, oats or any other gluten-containing cereal among their ingredients. For most people avoiding gluten day to day, that's the information that matters most, and on that basis they're generally treated as a safe pick.
Why that's not quite the same as "certified gluten-free"
Not listing gluten-containing ingredients isn't the same as formal gluten-free certification. Mars doesn't put UK Skittles through that certification process, so you won't find a "gluten-free" logo on the pack, and the brand doesn't make a guarantee about cross-contamination risk in its factories. For most people, uncertified-but-no-gluten-ingredients is fine. For anyone with coeliac disease or a diagnosed gluten intolerance, that distinction matters more, and we'd always recommend checking the current pack and, if in doubt, contacting Mars directly before relying on anything written online - including this.
Check the specific product
As with the vegan question, the rule is the same: check the product in front of you rather than assuming the whole brand is identical. Formulations, and the factories products are made in, can differ between varieties and between countries, so a US answer or an old pack photo isn't a reliable stand-in for the current UK ingredients list.
What we stock
We stock Skittles in small bags, treat bags across several flavours, and a 1.6kg bulk vending bag for events or resale. For the vegan side of Skittles specifically, see our Skittles vegan guide.
