Plain still water is the most straightforward bottled choice for a school packed lunch: NHS guidance recommends water and milk as drinks for children and advises avoiding sugary fizzy drinks, squash and juice drinks. If a child prefers flavour or bubbles, check the exact drink’s label and the school’s packed-lunch policy before choosing flavoured or sparkling water.
Plain water avoids the label distinctions between sugary, low-sugar and no-added-sugar flavoured drinks. NHS guidance recommends water and milk as drinks for children and advises avoiding sugary fizzy drinks, squash and juice drinks.
If a child dislikes plain water, flavour or carbonation may be worth considering. Check sugars, ingredients and the school’s rules for the particular drink rather than assuming every flavoured or sparkling option is alike.
Individual bottle size, pack format and whether a child can manage the container matter for repeated school use. A mineral-water brand name alone does not resolve those practical choices.
Start with plain water, then consider flavour or carbonation if it suits the child and the school permits it. For any flavoured drink, compare the exact product label rather than relying on a range name.
Choose when: A straightforward lunch drink without added flavourings is the priority.
Consider: A child who dislikes plain water may not finish the bottle; choose a manageable container and size.
Consider when: Flavour makes water more appealing to the child and the school permits the drink.
Check: No-added-sugar, sugar-free and low-sugar claims describe different products; ingredients can differ too.
Consider when: The child likes carbonation and the school allows sparkling drinks.
Check: Plain sparkling water is not the same product as a sweetened fizzy drink.
| Priority | What to check | Your needs |
|---|---|---|
| Added sugar | For flavoured drinks, compare the sugars figure per 100ml and per serving. Read the exact claim on the pack. | I want a lunch drink without added sugar. Plain water avoids having to distinguish between flavoured products with different sugar claims. |
| Flavour and ingredients | Check whether the drink is plain, flavoured or sparkling. For flavoured water, read the ingredients for sweeteners and acids. | If plain water is often left unfinished, I want an alternative the child likes without assuming it has the same ingredients as water. |
| School rules | Read the current packed-lunch policy for flavoured drinks, fizzy drinks and container requirements. | Before buying several bottles, I need to know whether this particular drink and container can go in the lunchbox. |
| Container and size | Check the volume of each bottle or can, whether it reseals and whether the child can use it independently. | A drink that fits the lunchbox and is manageable for the child matters more to me than a larger pack alone. |
Flavoured water may contain sweeteners, acids or flavourings even when it has no added sugar. Sainsbury’s lists sucralose and citric acid in its no-added-sugar lemon and lime flavoured water.
For a plain-water choice, select plain still water. Otherwise, compare the sugars figures and ingredients on the exact flavour.
Volvic describes its Touch of Fruit range as low in sugars, while Tesco lists separately named sugar-free Touch of Fruit products. Those descriptions should not be treated as one claim about every variant.
Check whether the bottle you are buying says sugar-free, no added sugar or low sugar, then read its nutrition panel.
The Department for Education’s school-food requirements concern food and drink provided in state-funded schools in England; an individual school can also specify what belongs in a packed lunch brought from home.
Check the school’s current policy before choosing flavoured or sparkling water or a particular container format.
A multipack may be impractical for school use if its drink or container format does not meet the local policy.
Mineral content does not tell you whether a flavoured drink contains sugar or other ingredients, and it does not establish which bottle format will suit the child.
Choose the drink type first, then compare the exact label, individual container and pack size.
These examples show why the precise product matters: a brand may sell both plain and flavoured water, while a retailer may list several container sizes.

Six individual 500ml bottles offer a format to consider for school lunches. Check the exact pack label for its ingredients and whether it is still or sparkling before deciding if it fits the intended drink choice.
Plain water is a straightforward routine choice. NHS guidance recommends water and milk as drinks for children and advises avoiding sugary fizzy drinks, squash and juice drinks.
No. A no-added-sugar drink can still contain other ingredients: Sainsbury’s lemon and lime flavoured water, for example, lists sucralose and citric acid. Read the exact product’s ingredients and sugars figures per 100ml and per serving.
Check the school’s packed-lunch policy first. Plain sparkling water may suit a child who likes carbonation, but it should not be confused with a sugary fizzy drink.
The Department for Education’s guidance describes legal requirements for food and drink provided in state-funded schools in England, not a single UK-wide rule specifying a bottled drink for lunches packed at home. Check the individual school’s packed-lunch policy; do not apply the England guidance to other UK nations without checking their rules.
Clean it after each use. Safefood advises using a dishwasher at 60°C if the bottle is dishwasher-safe, or washing it in warm soapy water, paying particular attention to the mouth spout.
