For an afternoon cola, check the sugars on the nutrition panel and then choose the exact variant according to whether you want caffeine. Coca-Cola Zero Sugar and standard Pepsi Max list 0g sugars but contain caffeine flavouring; Pepsi Max Caffeine-Free, Diet Coke No Caffeine and Tesco Caffeine Free Diet Cola offer caffeine-free alternatives. No-added-sugar fizzy drinks can still be acidic, so water is worth considering if you regularly sip a drink between meals.
Anyone looking for a cola-style alternative to a sugary fizzy drink can compare the listed sugars per 100ml and per serving. The NHS includes sugar-free, diet and no-added-sugar drinks among alternatives to sugary fizzy drinks.
Check the exact variant rather than the brand: Pepsi Max Caffeine-Free, Diet Coke No Caffeine and Tesco Caffeine Free Diet Cola are labelled caffeine-free, unlike their standard caffeinated counterparts.
A single serving, a multipack of cans and a larger bottle serve different snack routines. Compare the stated pack size and caffeine status before choosing an own-label or branded option.
Start with the nutrition panel and caffeine statement for the exact variant; then consider how and when you will drink it.
| Priority | What to check | Your needs |
|---|---|---|
| Listed sugars | Compare sugars per 100ml and per serving on the pack. Check energy on the same serving basis rather than relying on a no-added-sugar name. | I want a cola-style drink with little or no sugar listed for the amount I will actually drink. |
| Caffeine | Look for an explicit Caffeine-Free or No Caffeine variant and check its ingredients. Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine flavouring. | If I avoid caffeine in the afternoon, I need the caffeine-free version, not simply a zero-sugar one. |
| Acidity | Consider how often you sip fizzy cola between meals. NHS oral-health guidance says diet fizzy drinks can still be acidic and wear enamel. | For a drink I sip frequently, I would consider water instead of assuming that removing sugar also removes the acidity concern. |
| Pack format | Compare the number and size of cans with the stated bottle size. Recheck the exact variant when moving between pack formats. | A can may suit one afternoon snack; a larger bottle or multipack suits a different storage and serving routine. |
NHS oral-health guidance says that acid in diet fizzy drinks without sugar can wear tooth enamel.
If you often sip a drink between meals, consider water instead. NHS guidance also advises waiting at least 30 minutes after eating before brushing.
Coca-Cola Zero Sugar and standard Pepsi Max list caffeine flavouring, while separately named caffeine-free variants are available.
If you are avoiding caffeine, check the full variant name and ingredients rather than selecting by brand alone.
No-added-sugar products do not all have identical nutrition figures or ingredients. Tesco advises checking the physical label because products can be reformulated.
Check sugars and energy for the serving you intend to drink, along with caffeine, sweeteners and any phenylalanine declaration relevant to you.
The Department for Education states that School Food Standards are legally required for state-funded schools in England. A cola’s sugar claim alone does not establish whether it meets the applicable requirements.
For school provision, check the current standards and the school’s catering policy for the specific drink rather than relying on its retail label.
These examples identify variants and label details to compare; a brand name on its own does not tell you whether a cola contains caffeine.

Pepsi UK lists both standard Pepsi Max and a separately named Pepsi Max Caffeine-Free.
Tesco lists distinct standard and caffeine-free own-label cola variants.
