Carers replacing a sugary fizzy drink
If the aim is to change what is served with an after-school snack, compare total sugars per 100ml and per serving. A ‘no added sugar’ claim alone does not give the finished drink’s sugar value.
Who is this choice for?
Families avoiding caffeine after school
A zero-sugar cola is not necessarily caffeine-free. Check the exact variant: Pepsi Max No Caffeine and Coca-Cola Zero Sugar Caffeine Free are labelled caffeine-free, while standard Pepsi Max and Dr Pepper Zero list caffeine.
Carers choosing a regular snack-time drink
If a fizzy drink is becoming part of the daily routine, the choice is about more than its sugar label. Cambridgeshire Community Services NHS Trust advises replacing fizzy drinks, including sugar-free ones, with water.
What should you check?
Start with the nutrition panel, then check the exact variant’s ingredients and how often the drink would be served.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Read ‘of which sugars’ per 100ml and per serving. Check the exact pack even when the front says ‘no added sugar’: the Advertising Standards Authority distinguishes the claim from the finished drink’s total sugars. | I’m swapping a sugary fizzy drink and want to know how much sugar the drink I’ll serve actually contains. |
| Caffeine | Look for an explicit caffeine-free label and check the ingredients. Standard and caffeine-free variants within a brand are separate products. | Caffeine is something I want to avoid after school, so a zero-sugar label on its own is not enough. |
| Serving and ingredients | Compare the can or bottle size with the nutrition values per serving. Read sweetener and ingredient statements on the purchased variant, including any phenylalanine notice relevant to your household. | I want to understand the drink in the portion I’m serving, not just its front-of-pack description. |
| Everyday routine | Consider whether this is an occasional flavoured drink or the regular snack-time drink. Cambridgeshire Community Services NHS Trust advises water instead of fizzy drinks, including sugar-free ones. | For an everyday drink after school, I’d choose water rather than make a sugar-free fizzy drink the default. |
Common buying mistakes
-
Reading ‘no added sugar’ as ‘no sugar’
The claim concerns what was added; total sugars can still appear in the nutrition panel. The Fanta Zero Orange listing, for example, says ‘zero sugar added’ and identifies naturally occurring sugars.
Check ‘of which sugars’ per 100ml and per serving before choosing.
-
Assuming every zero-sugar cola is caffeine-free
Standard Pepsi Max and Dr Pepper Zero list caffeine, while caffeine-free cola variants are labelled separately.
When caffeine avoidance matters, check both the full variant name and the ingredients on the pack you buy.
-
Making a sugar-free fizzy drink the daily default
A zero-sugar label does not make a fizzy drink equivalent to water as a regular choice. Cambridgeshire Community Services NHS Trust advises replacing even sugar-free fizzy drinks with water.
Keep water as the routine after-school drink and choose a fizzy drink for an occasional preference.
-
Using retail HFSS rules to judge school drinks
Department of Health and Social Care guidance on HFSS retail promotions concerns businesses selling to England. Department for Education guidance separately addresses food and drink provided in state-funded schools in England; neither makes a front-of-pack claim a school eligibility decision.
For a privately bought after-school drink, check its label and ingredients. If a school supplies the drink, ask the provider which rules and policy apply.
Brand and variant references
A brand name is not enough to establish sugar or caffeine content: the labelled variant is what matters.
Coca-Cola
Coca-Cola Zero Sugar Caffeine Free is the relevant cola variant when both sugar and caffeine are being checked.
- Coca-Cola GB describes this specific variant as containing neither sugar nor caffeine.
- Do not transfer its caffeine-free description to other Coca-Cola variants; check the exact pack and its ingredient notices.
Pepsi
Pepsi Max No Caffeine and standard Pepsi Max answer different caffeine requirements.
- Pepsi UK describes Pepsi Max No Caffeine as having zero sugar and zero caffeine.
- Standard Pepsi Max lists caffeine, so confirm which variant you are buying.
Sprite
Sprite Zero offers a lemon-and-lime alternative when cola flavour is not wanted.
- Coca-Cola GB describes Sprite Zero as having no sugar.
- If caffeine avoidance is essential, check the exact pack rather than assuming its status from the flavour.
Fanta
Fanta Zero Orange illustrates why ‘zero sugar added’ and total sugars need separate checks.
- The ASDA listing identifies naturally occurring sugars alongside its ‘zero sugar added’ wording.
- Read the nutrition panel for the exact Fanta variant and serving size rather than treating the front claim as a total-sugar value.
Dr Pepper
Dr Pepper Zero is a zero-sugar option to consider only if caffeine is acceptable.
- The Tesco listing for Dr Pepper Zero declares 0g sugars.
- That listing includes caffeine in the ingredients, so it does not meet a caffeine-free requirement.

Frequently asked questions
Does ‘no added sugar’ mean there is no sugar in the drink?
No. The Advertising Standards Authority explains that the claim concerns added sugars, not the finished drink’s total sugars. Check ‘of which sugars’ on the nutrition panel; the Fanta Zero Orange listing says ‘zero sugar added’ while identifying naturally occurring sugars.
Are zero-sugar fizzy drinks caffeine-free?
Not necessarily. Standard Pepsi Max and Dr Pepper Zero list caffeine, whereas Pepsi Max No Caffeine and Coca-Cola Zero Sugar Caffeine Free are labelled caffeine-free. Check the full name and ingredients of the exact pack.
Should a sugar-free fizzy drink be the everyday after-school drink?
Cambridgeshire Community Services NHS Trust advises water instead of fizzy drinks, including sugar-free versions, as the regular choice. A lower-sugar fizzy drink can be considered as an occasional alternative to a sugary one without making it the daily default.
Does a ‘no added sugar’ label tell me whether a school can supply the drink?
No. Department for Education guidance addresses food and drink provided in state-funded schools in England; a packaging claim does not establish whether a drink meets the applicable requirements. If a school supplies it, ask the provider about its current rules and policy rather than applying England’s retail HFSS promotion guidance to a school meal.
