ONE Water 500ml Still
£1.90–£3.35*
Updated 12 September 2026 · price from a third party listing
ONE Water 500ml Still sits 3rd of 107 on price in Starbucks’ featured section, at £1.90–£3.35. Updated 12 September 2026.
British spring water in 100%* recycled plastic bottles and 100% recyclable. *excludes cap and label
The £1.90–£3.35 figure came from a third party listing rather than from Starbucks, which means it may reflect a delivery menu. Delivery prices sit above in restaurant prices before any fee is added, so treat this as the ceiling rather than the till price.
Allergens Starbucks declares
None of the 14 regulated allergens is listed as an ingredient.

Everything You Need to Know About Starbucks ONE Water 500ml Still
How to order ONE Water 500ml Still at Starbucks
ONE Water 500ml Still is available at the till, on the kiosk screens and through the Starbucks app, for collection or for delivery. It is filed under featured. Not every branch stocks it, and the app is honest about that before you pay.
Starbucks ONE Water 500ml Still price in 2026
The Starbucks ONE Water 500ml Still price in 2026 is £1.90–£3.35 on the figures we hold, with branch to branch variation between £1.90 and £3.35. The figure came from a third party listing rather than from Starbucks, so read it as a ceiling. Within the featured section that puts it 3rd of 107 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
Where it sits on price
2 items cost less than this one in the featured section and 104 cost more, out of 107 we hold a price for. The closest thing to it on price is ONE Water 500ml Sparkling at £1.90–£3.35, so those two are the real comparison when you are deciding.
Allergens declared
Starbucks 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.
Diet marking
Starbucks marks this as vegan and 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.
Finding it near you
We list 176 Starbucks branches across 4 of the four UK nations, with the Edinburgh postcode area holding the most at 16. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Starbucks app confirms it in seconds.
Pro Tips for Ordering ONE Water 500ml Still
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.
