Caffeine-free fizzy drinks in the UK
Find the exact caffeine-free variant—not just a familiar brand name or a “Zero” label.
The short answer
The manufacturers identify the UK options below as caffeine-free. Standard Diet Coke and ordinary Pepsi MAX are different products. Sugar-free doesn’t automatically mean caffeine-free, and decaf isn’t the same claim.
This is a limited, source-linked directory, not a complete survey of UK shops. Availability, flavours and imported recipes can differ. Check the current pack; caffeine status isn’t a recommendation about sugar, nutrition or health.

Statement reviewed 2026-10-24How this directory was checked
Inclusion requires an explicit UK manufacturer statement. We don’t infer caffeine absence from calories, colour, missing milligram values or an ordinary brand name. These statements don’t add unverified serving volumes to the calculator.
What about drinks not listed?
Ask the manufacturer or inspect the exact current product label. Ingredient information can help identify caffeine-containing ingredients without quantifying them. Unknown remains unknown; it isn’t entered as zero.
