Choose plain still water if you want no added sugar without having to assess flavourings or sweeteners. If you prefer fruit flavour, choose an exact bottle labelled no added sugar or sugar free and check its ingredients; a sugar-free flavoured water can still contain sweeteners and acids. Plain sparkling water offers fizz, while bottle size and pack quantity matter for a short desk lunch.
Plain still water avoids a separate flavouring or sweetener choice. For an individual desk lunch, a 500ml format is available in the still-water ranges described by Highland Spring and Buxton; evian also lists a portable 500ml bottle.
Look for no added sugar or sugar free on the exact flavoured bottle, then read its ingredients. Volvic lists 0g sugars per 100ml for its Strawberry Sugar Free 1.5L product, which also contains sweeteners, citric acid and potassium benzoate.
Plain sparkling water gives you carbonation without choosing a flavoured drink. If you sip it repeatedly through a long working day, bear in mind Buxton’s advice that some sparkling waters have a lower pH than still water.
Choose it when: You want a drink for lunch without choosing a flavour or checking a sweetener preference.
Trade-off: It does not offer fruit flavour or fizz.
Choose it when: You want fruit flavour and the exact product is labelled no added sugar or sugar free.
Trade-off: The formulation may include sweeteners, acids or preservatives, so the ingredients matter as well as the sugars value.
Choose it when: You prefer fizz but do not need a flavoured drink.
Trade-off: Buxton notes that some sparkling waters have a lower pH than still water, a consideration if you sip them frequently.
| Priority | What to check | Your needs |
|---|---|---|
| No added sugar | For flavoured water, read the exact pack’s claim, sugars per 100ml and ingredients. Do not treat low sugar as the same claim as no added sugar. | I want to rule out a flavoured drink that still contains added sugar. NHS guidance advises checking drinks’ nutrition labels. |
| Ingredients | Check whether the chosen flavour contains sweeteners, acids or preservatives. Volvic lists these ingredients for its Strawberry Sugar Free 1.5L product. | Fruit flavour appeals to me, but I also care about what makes the drink sweet or tart. |
| Bottle format | Check individual bottle size, closure and the number of bottles in the pack. Highland Spring lists both screw-cap and sports-cap options in its smaller still-water formats. | For a short desk lunch, I would rather carry one manageable container than open a large bottle. |
| Still or sparkling | Check that a sparkling choice is plain if you do not want flavour additions. Buxton notes that some sparkling waters have a lower pH than still water. | I enjoy fizz, or I may prefer still water when I expect to sip my drink over a longer stretch. |
A low-sugar description does not establish the no-added-sugar condition. Volvic’s Lemon & Lime 500ml ingredient list, for example, includes sugar.
Read the claim, sugars line and ingredients for the precise flavour and size you plan to buy. If you also want to avoid sweeteners, check for those separately.
A larger bottle may be less convenient to carry and use at a desk than an individual 500ml format.
Check the size of each container as well as the pack quantity; Highland Spring and Buxton both list 500ml still-water bottles.
Buxton notes that some sparkling waters have a lower pH than still water and can have higher erosive potential; this does not apply equally to every sparkling product or drinking pattern.
Choose fizz if you prefer it, while considering plain still water if you expect to sip repeatedly across a long work session.
Flavours and formats within a range need not have the same ingredients or sugars value.
Check the product name, ingredients and nutrition panel for the exact bottle before buying.

No. For this purchase, choose plain water or a flavoured bottle explicitly labelled no added sugar or sugar free, then check the exact pack’s nutrition panel and ingredients. Volvic’s Lemon & Lime 500ml product, for example, is described as low sugar but lists sugar as an ingredient.
Yes, when the exact flavoured product is labelled accordingly and its ingredients suit you. Highland Spring describes its flavoured still range as no added sugar; Volvic lists 0g sugars per 100ml for Strawberry Sugar Free 1.5L, which also contains sweeteners, citric acid and potassium benzoate.
A 500ml individual bottle is a practical starting point if portability matters. Highland Spring and Buxton list 500ml still-water formats, and evian lists a portable 500ml bottle; also check whether you are buying one bottle or a multipack.
Yes, if you prefer fizz; the NHS includes sparkling water as an option for people who do not enjoy the taste of plain water. For frequent sipping, consider Buxton’s qualification that some sparkling waters have a lower pH than still water, rather than assuming every sparkling product is the same.
