For a workplace lunch, choose unflavoured still water if you want a drink without flavourings or sweeteners. Plain sparkling water offers bubbles, while sugar-free flavoured water offers flavour; for either option, check the exact label rather than assuming that ‘sugar free’ describes every ingredient or consideration. If acidic fizzy drinks are a dental concern, still water avoids the carbonation trade-off identified in NHS dental guidance.
Who is choosing?
Employees cutting back on sugary lunch drinks
If you usually buy a drink with your canteen meal, plain water avoids the need to assess a flavoured drink’s sugar, energy and ingredients. A sugar-free flavoured option may suit you when you want flavour; check its own label.
Workers following a diabetes-related drink plan
Choose a lunch drink that fits your existing plan and check the nutrition panel of any flavoured option. Diabetes UK includes water and sugar-free drinks among drink choices for people living with diabetes; that guidance does not make every flavoured product interchangeable.
People who like fizz but are concerned about acidity
Plain sparkling water offers carbonation without choosing a sweet fizzy drink, but sugar content and acidity are different questions. Northumbria Healthcare NHS Foundation Trust warns that sugar-free fizzy drinks can contribute to tooth erosion; still water avoids carbonation if acidic drinks are a concern.
What matters when choosing?
Start with whether you want plain still water, bubbles or flavour. Then check the label and pick a pack you can use and store at work.
| Priority |
What to check |
Your needs |
| Sugars and energy |
Distinguish unflavoured water from flavoured drinks. For the latter, read sugars and energy per 100ml and check the serving size. |
I want a lunch drink without overlooking sugars or energy in a flavoured option. |
| Flavour and ingredients |
Check the full ingredients list as well as a ‘sugar free’ claim. Volvic UK lists 0g sugars and 1 kcal per 100ml for Touch of Fruit Sugar Free Watermelon, alongside citric acid, a preservative and sweeteners. |
Flavour would make a change from plain water, but I want to know what is in the drink. |
| Carbonation |
Check whether the water is still or sparkling. Highland Spring reports a pH of 4–5 for its sparkling water; Northumbria Healthcare NHS Foundation Trust cautions that sugar-free fizz can contribute to tooth erosion. |
I like bubbles with lunch, but I would choose still water if acidic drinks are a concern for me. |
| Pack and storage |
Choose an individual bottle or a shared container to suit workplace use. Follow the particular pack’s opened-bottle instructions: Sainsbury’s says to refrigerate its 5L still spring water and use it within three days of opening. |
A small bottle is easier to carry to lunch; a shared container needs fridge space and a plan for using it after opening. |
| Water category |
Read ‘spring water’ and ‘natural mineral water’ as distinct label categories, not diet ratings. UK government guidance requires natural mineral water to state its mineral composition; spring water need not do so. |
If a particular mineral matters to my own plan, I want the stated composition rather than assuming one category suits me better. |
Common buying mistakes
-
Assuming flavoured water is the same as plain water
A sugar-free claim addresses sugar, not every ingredient. Volvic UK’s Touch of Fruit Sugar Free Watermelon lists citric acid, potassium benzoate and sweeteners.
Read both the nutrition panel and ingredients list. Choose unflavoured water when you want water without added flavourings or sweeteners.
-
Equating sugar-free fizz with non-acidic water
Sugar reduction and acidity are separate considerations. Northumbria Healthcare NHS Foundation Trust warns that sugar-free fizzy drinks can contribute to tooth erosion.
If acidic drinks are a concern, consider still water rather than judging a fizzy drink by its sugar claim alone.
-
Buying a large container without a storage plan
A container intended for shared use may be awkward for an individual lunch. Sainsbury’s says its 5L still spring water must be refrigerated after opening and used within three days.
Check fridge space and the exact pack’s instructions before choosing a large container for work.
-
Using water-category names as diet ratings
UK government guidance distinguishes spring water from natural mineral water by source and composition rules; the names do not rank drinks for a lower-sugar lunch.
Check whether the drink is plain or flavoured, then consult its nutrition, ingredients and mineral information where relevant.
Brand and retailer references
These examples illustrate different water formats and label details; brand information does not establish that a particular product is available on Joybuy.
Highland Spring
Spring water offered in still and sparkling formats.
- Highland Spring states that its water contains 0.0056g sodium per litre.
- The brand reports pH 4–5 for its sparkling water; consider the carbonation separately from sugar content.
Evian
Natural mineral water offered in individual bottles and larger formats.
- Evian lists, per litre of its 1L natural mineral water, 80mg calcium, 26mg magnesium and 6.5mg sodium.
- Those figures describe the stated composition of that product, not a diet advantage over other waters.
Volvic
Offers plain natural mineral water and Touch of Fruit sugar-free flavoured drinks.
- Volvic lists 0g sugars and 1 kcal per 100ml for Touch of Fruit Sugar Free Watermelon.
- That Watermelon product also lists citric acid, potassium benzoate, acesulfame K and sucralose; check the specific flavour rather than treating it as plain water.
Buxton
Natural mineral water offered in still and sparkling formats.
- Buxton lists, per litre of its still water, 24mg sodium, 55mg calcium and 19mg magnesium.
- Buxton reports pH 7.4 for its still water and pH 5.2 for its sparkling water; these brand figures should not be applied to every sparkling product.
Sainsbury’s
Own-label British still spring water includes a 5L format for shared use.
- A 5L container may fit a shared workplace kitchen better than an individual carry-to-lunch bottle.
- Sainsbury’s instructs users to refrigerate that 5L product after opening and use it within three days.

Questions about lunch drinks
Is plain bottled water a straightforward choice for a lower-sugar lunch?
Yes: choose unflavoured water if you want to avoid added flavourings and sweeteners in your lunch drink. The NHS identifies water as a hydration choice; check the label rather than assuming every drink described as water is unflavoured.
Is sugar-free flavoured water the same as plain water?
No. Check both the nutrition panel and ingredients for the exact flavour. Volvic UK lists 0g sugars and 1 kcal per 100ml for Touch of Fruit Sugar Free Watermelon, but also lists citric acid, potassium benzoate and sweeteners.
What if I prefer sparkling water with lunch?
Plain sparkling water is an option if you prefer bubbles; the NHS suggests it for people who do not like the taste of still water. Sugar content does not settle the acidity question: Northumbria Healthcare NHS Foundation Trust warns that sugar-free fizz can contribute to tooth erosion. Consider still water if acidic drinks are a concern.
Do ‘spring water’ and ‘natural mineral water’ mean different things?
Yes. UK government guidance treats them as distinct regulated categories: natural mineral water must have a stable mineral composition and state it on the label, while spring water does not have to state its composition. Neither name alone tells you whether a flavoured drink fits your lunch preference.
How should a large bottle be kept in a workplace kitchen?
Follow that product’s label rather than applying one storage period to every bottle. Sainsbury’s instructs users to refrigerate its 5L still spring water after opening and use it within three days, so check that the fridge space and likely use suit the pack.
