Diet Pepsi - Regular at KFC carries 2 kcal and 0g of protein. Updated 12 September 2026.
The price is missing here for a reason. KFC does not publish one we could check, and a guess dressed as a figure is worse than an honest gap.
Allergens KFC declares
None of the 14 regulated allergens is listed as an ingredient.

Everything You Need to Know About KFC Diet Pepsi - Regular
How to order Diet Pepsi - Regular at KFC
Counter, kiosk and app all carry it. The KFC app adds collection and delivery. It is filed under Drink. Availability is set per branch, so a smaller site may not carry it at all.
KFC Diet Pepsi - Regular price in 2026
There is no verified KFC Diet Pepsi - Regular price for 2026. KFC prices per branch and publishes no national list for it, so the accurate figure is the one your own branch shows in 2026. Any site quoting a single exact national price for this item is guessing, and we would rather show the gap.
Allergens declared
KFC lists none of the 14 allergens UK law regulates as an ingredient of this item. A declaration covers the recipe and not the kitchen, and every one of these chains prepares food in shared fryers and on shared surfaces. For a severe allergy the only reliable check is asking staff on the day.
Finding it near you
We list 890 KFC branches across 4 of the four UK nations, with the Northern Ireland postcode area holding the most at 32. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The KFC app confirms it in seconds.
What 2 kcal means here
2 kcal is well below the Drink average. On its own it is a small addition to a day rather than a meal. The 2,000 kcal figure printed on UK menus is a reference intake for an average adult, not a target, and it is the number these percentages are worked against.
Diet marking
KFC marks this as vegetarian. That is the chain's own classification of the recipe rather than a statement about how it is cooked, and vegan marking in particular sits alongside shared equipment at most of these brands.
Pro Tips for Ordering Diet Pepsi - Regular
Sizes and sugar
Soft drink figures scale almost exactly with cup size, so the published number tells you what the standard serve holds and nothing about the refill. Sugar free versions sit near zero on energy at every one of these chains, which is the single largest swap available on a drink.
