Families packing a daily school lunch
Plain water is a straightforward choice when the pupil will drink it. Consider whether the bottle fits the lunchbox and whether its closure is easy for the pupil to use.
Who is this choice for?
Pupils who prefer a flavoured drink
A sugar-free flavoured water is an option to consider, but check the exact flavour’s nutrition panel and ingredients. Volvic UK’s Sugar Free Lemon & Lime, for example, lists 0.0g sugars per 250ml serving alongside citric acid, a preservative and sweeteners.
Families avoiding caffeine
Check water-based drinks marketed as functional or enhanced products. Buxton labels its Peak FOCUS Lemon & Mint drink, which contains 75mg caffeine per bottle, as not recommended for children.
What should you check?
Start with the type of drink, then check the exact label and whether the bottle works for the pupil’s school day.
| Priority | What to check | Why it matters to me |
|---|---|---|
| Everyday drink | Decide whether the pupil will drink plain still water. NHS guidance identifies water and milk as suitable drinks for children. | I want a straightforward lunch drink without choosing a flavoured product. |
| Sugars and flavouring | Read sugars per 100ml and per serving, then check the ingredients for the exact flavour. Volvic UK lists 0.0g sugars per 250ml serving for Touch of Fruit Sugar Free Lemon & Lime; it separately describes Touch of Strawberry as low sugar, with 25 calories per serving. | If I choose a flavoured drink, I want to know whether it is sugar free or low sugar, and whether its other ingredients suit our preferences. |
| Caffeine | Look for a caffeine amount and any warning for children on functional-water drinks. Buxton Peak FOCUS Lemon & Mint lists 75mg caffeine per bottle and says it is not recommended for children. | A water-based name alone does not tell me whether the drink is appropriate for a school lunch. |
| Bottle and closure | Check the volume, whether the pupil can open and close it, and whether it fits their bag. Highland Spring lists 330ml, 500ml and 750ml still-water bottles with screw-cap or sports-cap formats. | I need a drink the pupil can carry and use during the school day. |
| School rules | Check the school’s packed-lunch policy before choosing flavoured, sparkling or unusually large bottles. The Department for Education’s September 2026 school-food guidance concerns food and drink provided in state-funded schools in England; it does not establish an individual school’s packed-lunch policy. | I want the drink I pack to meet my pupil’s school requirements. |
Common buying mistakes
-
Assuming all flavoured water is like plain water
“Low sugar” and “sugar free” describe different products, while sugar-free flavoured water can still contain acids, preservatives or sweeteners. Volvic UK’s Sugar Free Lemon & Lime lists these ingredients alongside 0.0g sugars per 250ml serving.
Compare the nutrition panel and ingredient list for the exact flavour rather than relying on the front-of-pack description.
-
Overlooking caffeine in a functional drink
Buxton Peak FOCUS Lemon & Mint contains 75mg caffeine per bottle and is labelled as not recommended for children.
Check the caffeine declaration and child warning before putting a water-based functional drink in a school lunch.
-
Using school-food guidance as a packed-lunch rule
The Department for Education’s September 2026 guidance addresses food and drink provided in state-funded schools in England, not the contents of every lunch packed at home.
Check the pupil’s own school policy before regularly sending flavoured or sparkling water, or a larger bottle.
-
Choosing a bottle by volume alone
A bottle still needs to fit the pupil’s bag and have a closure they can manage.
Compare the size and cap on the specific product. Highland Spring, for example, lists screw-cap and sports-cap options in 330ml, 500ml and 750ml still-water bottles.
Brand ranges to recognise
These ranges illustrate why bottle format and product labels matter; a brand name alone does not identify the drink’s ingredients or suitability for a particular school.
Highland Spring
Highland Spring lists plain still spring water in several bottle sizes.
- Its still-water range includes 330ml, 500ml and 750ml bottles with screw-cap or sports-cap options.
- Check the size and cap of the product you choose; assess flavoured products separately from plain spring water.
Volvic
Volvic UK lists natural mineral water, Touch of Fruit and Touch of Fruit Sugar Free as separate ranges.
- The range offers a distinction between plain water and flavoured products.
- Volvic UK’s Sugar Free Lemon & Lime lists citric acid, a preservative and sweeteners; check the formulation of the exact variant.
Buxton
Buxton lists still and sparkling mineral water alongside its separate Peak range.
- Its standard still mineral water is a plain-water option.
- Buxton Peak FOCUS Lemon & Mint lists 75mg caffeine per bottle and is labelled as not recommended for children.
Evian
Tesco Groceries lists Evian natural mineral still water in formats including 500ml bottles.
- A 500ml bottle is a format to consider for a packed lunch.
- Check the label of the exact bottle when its ingredients or nutrition information matter to your choice.
Tesco
Tesco Groceries lists its British Natural Mineral Water Still in several formats, including 12 × 500ml.
- The listed 500ml bottles offer a pre-portioned format for packed lunches.
- Check the individual product listing for the format you intend to buy.

Frequently asked questions
Should I pack plain water or a sugar-free flavoured water?
Choose plain water if the pupil will drink it; NHS guidance identifies water as a suitable drink for children. If they prefer flavour, a sugar-free option is worth considering after checking the exact bottle’s sugars and ingredients. Volvic UK’s Sugar Free Lemon & Lime, for example, lists 0.0g sugars per 250ml serving but also contains citric acid, a preservative and sweeteners.
Does “low sugar” mean “sugar free” on flavoured water?
No. Volvic UK describes Touch of Strawberry as low sugar and lists 25 calories per serving, while its separate Touch of Fruit Sugar Free Lemon & Lime lists 0.0g sugars per 250ml serving. Read the nutrition panel for the exact flavour rather than treating those labels as interchangeable.
Can a drink labelled as water contain caffeine?
Yes. Buxton Peak FOCUS Lemon & Mint lists 75mg caffeine per bottle and carries a warning that it is not recommended for children. Check functional-water labels for caffeine before choosing a packed-lunch drink.
Do England’s school-food rules tell me what to pack?
The Department for Education’s September 2026 school-food guidance concerns food and drink provided in state-funded schools in England. For a lunch packed at home, check the pupil’s school policy rather than assuming that guidance states the school’s requirements.
