Parents choosing a daily lunch drink
If the drink will go to school every day, the main choice is between plain still water and a fizzy drink. Check the school’s packed-lunch policy as well as the type of drink.
Who is this choice for?
Pupils who prefer fizz
Plain sparkling water offers carbonation without choosing a sugary fizzy drink, but that distinction does not settle whether it belongs in a daily packed lunch. Its occasional use still depends on the school’s rules.
Families comparing plain and flavoured drinks
A sparkling-water label can describe either plain carbonated water or a flavoured drink with additional ingredients. Read the individual ingredient list rather than judging by the word “water” or a sugar claim alone.
What should you check before buying?
Start with how often the drink will be packed and what the school permits. Then compare the ingredient list and the container you would actually send.
| Priority | What to check | Your needs |
|---|---|---|
| Daily drink | Check whether the water is still or carbonated. For frequent school use, consider Medway Community Healthcare’s caution about acidic fizzy drinks; its published guidance is for younger children, not a measured risk estimate for teenagers. | I’m choosing something to pack each school day, rather than an occasional fizzy drink. Plain still water fits that distinction. |
| Ingredients | Read the ingredient list as well as the sugar declaration. Look for added acids, flavourings and sweeteners when comparing flavoured drinks with plain sparkling water. | “Low sugar” is not enough for me to identify a plain drink. Marks & Spencer’s Blood Orange Sparkling Water, for example, lists citric acid and steviol glycosides. |
| School rules | Check the current packed-lunch drink policy. Confirm whether sparkling water is accepted and whether the school restricts cans, glass or other containers. | Before buying a multipack, I want to know that the school will accept both the drink and its container. |
| Pack format | Compare the stated portion size and pack quantity with occasional use. Check the container material rather than assuming every bottle or can is suitable for school. | A smaller individual portion is easier for me to consider for a lunchbox than a large household bottle, provided the school permits it. |
Packed-lunch mistakes to avoid
-
Treating sparkling and still water as interchangeable every day
Being sugar-free does not remove the concern about acidic fizzy drinks. Medway Community Healthcare’s oral-health guidance cautions that even sugar-free fizzy drinks can wear tooth surfaces; its advice is written for younger children and does not quantify risk for secondary-school pupils.
Choose plain still water for the daily packed-lunch drink. If sparkling water is permitted, consider it an occasional alternative rather than assuming it has the same implications as still water.
-
Choosing a flavoured drink by its sugar claim alone
A sugar declaration does not describe every ingredient. Marks & Spencer’s Blood Orange Sparkling Water lists citric acid and a stevia-derived sweetener, so it is a different formulation from plain carbonated water.
Read the full ingredient list on the product you intend to buy, especially when comparing flavoured and unflavoured varieties.
-
Assuming every school accepts sparkling water
The Department for Education’s school-food guidance concerns food and drink provided in state-funded schools in England. It does not establish one UK-wide packed-lunch rule, while water-only school policies demonstrate why local requirements matter.
Check the pupil’s school policy for drinks brought from home and for permitted containers before buying a multipack.

Packing a large or unsuitable container
Highland Spring lists sparkling water in both 500ml and larger formats, while S.Pellegrino describes PET bottles for use on the go. Neither brand’s range determines what a particular school will accept.
If occasional sparkling water is permitted, choose a portion and container that fit the lunchbox and the school’s rules; do not assume glass or cans are allowed.
Brand and retailer references
These ranges illustrate differences in format and formulation; a brand name alone does not tell you whether a particular drink suits a school packed lunch.
Highland Spring
Highland Spring lists plain sparkling water in 500ml and larger formats.
- Its listed 500ml format is worth checking if the school permits an occasional sparkling drink.
- Plain sparkling water is still fizzy; do not treat the absence of flavouring as a reason to make it the daily default.
S.Pellegrino
Sanpellegrino UK describes PET bottles for use on the go and presents sparkling water alongside infused waters.
- PET is a format to consider where the school permits that type of container.
- Check the exact product label: plain mineral water and infused varieties should not be assumed to have the same ingredients.
Perrier
Perrier describes its plain sparkling mineral water as containing no sugar and zero calories.
- The plain product can be considered when the preference is for an occasional fizzy drink without sugar.
- Perrier’s cited product page is international; check the particular UK product and container before choosing it for school.
Tesco
Tesco Groceries lists Tesco British Natural Mineral Water Sparkling in a 12 × 500ml format.
- The listing gives a concrete individual-bottle format to compare with the intended use.
- Check the individual label and the school’s rules rather than assuming that every sparkling drink in a retailer’s range is plain water.
M&S
Marks & Spencer lists both sparkling mineral water and flavoured sparkling drinks.
- The range lets shoppers compare plain and flavoured product labels.
- Its Blood Orange Sparkling Water lists citric acid and steviol glycosides; check the current label rather than treating it as plain mineral water.

San Pellegrino Sparkling Natural Mineral Water, 6 × 0.5L

Common questions
Is sparkling water an everyday secondary-school packed-lunch drink?
Choose plain still water for the everyday packed lunch rather than making a fizzy drink the default. Medway Community Healthcare’s guidance for younger children cautions that acidic fizzy drinks, including sugar-free versions, can wear tooth surfaces; it does not establish that an occasional sparkling drink will cause damage to a secondary-school pupil.
Does a school have to allow sparkling water brought from home?
Do not assume it will: check that school’s current packed-lunch and container policy. The Department for Education describes requirements for food and drink provided in state-funded schools in England, not one UK-wide rule covering every packed drink brought from home.
Does a low-sugar label make flavoured sparkling water the same as plain water?
No. Sugar content does not describe the complete formulation. Marks & Spencer’s Blood Orange Sparkling Water lists citric acid and steviol glycosides, so read the current ingredient label when comparing it with plain sparkling water.
What size should I consider if sparkling water is permitted?
Choose a portion that fits the lunchbox and meets the school’s container rules. Highland Spring lists a 500ml sparkling-water format, while Sanpellegrino UK describes PET bottles for use on the go; neither detail means every school accepts the drink or its packaging.
