Oats count as a gluten cereal under UK labelling and ordinary oats are milled alongside wheat. Certified gluten-free oats are a separate ingredient here.
Most whey powders contain soya lecithin, which counts as soya. Check the tub.

Flags follow UK labelling rules and come from the ingredients as listed, not from any particular brand. Check the packet before cooking for somebody with an allergy.

Worth knowing

A small jar at 274 kcal, built for a morning when breakfast would otherwise be coffee. The oats are 35 g, which is on the light side.
Strong instant coffee dissolved in 30 ml of hot water does the same job as a shot if there is no machine.
