Shoppers cutting down on sugary drinks
If fizzy drinks are part of your household order, compare sugars per 100ml on the exact variant. A familiar flavour name alone will not tell you whether you have selected the regular or zero-sugar version.
Who is this choice for?
Cola drinkers avoiding caffeine
Look for ‘No Caffeine’ or ‘Caffeine Free’ in the full product name, then check the listing for the pack you intend to order. A diet or zero-sugar label does not establish caffeine status.
Households ordering multipacks
Check the can count, volume per can and total quantity before adding a pack to your basket. The right quantity depends on how much you want delivered and where you will keep it.
What should you check before ordering?
Start with the sugar figure for the exact variant, then check caffeine, ingredients and the quantity you will receive.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read sugars per 100ml on the exact variant. Coca-Cola GB lists 0g for Coca-Cola Zero Sugar, but 0.4g for Fanta Fruit Twist Zero; Pepsi UK lists 4.5g for standard Pepsi. | I want to cut down on sugary fizzy drinks without accidentally ordering the regular version of a familiar flavour. |
| Caffeine | Check for an explicit caffeine-free name and read the ingredients. Coca-Cola GB and Pepsi UK list caffeine or caffeine flavouring for their standard zero-sugar colas; both also describe named no-caffeine alternatives. | If I am avoiding caffeine, a ‘diet’ or ‘zero sugar’ label is not enough for me to choose the pack. |
| Flavour | Distinguish cola from lemon-lime and fruit flavours, then confirm the full variant name. Coca-Cola GB lists different sugar figures for regular Sprite and Sprite Zero, and for Fanta Orange and Fanta Fruit Twist Zero. | Our household prefers a particular flavour, but I still want to check which version I have added. |
| Ingredients | Read the current ingredients and any phenylalanine statement for the exact drink. The reviewed Coca-Cola GB and Pepsi UK zero-sugar product pages list sweeteners and state that the drinks contain a source of phenylalanine. | I need to check a particular ingredient or label statement rather than relying on the diet-drink category. |
| Pack size | Confirm the number of cans or bottles, individual volume and total quantity. Tesco Groceries lists diet-cola options in different pack formats. | Before delivery, I want to know how much space the order will take up and whether the quantity suits the household. |
Ordering mistakes to avoid
-
Choosing by flavour name alone
Regular and zero-sugar versions of a drink can have different sugar figures. Coca-Cola GB lists 4.4g sugars per 100ml for Sprite and 0g for Sprite Zero.
Add the full variant name to your basket and check sugars per 100ml on that product’s listing.
-
Assuming diet means caffeine-free
Coca-Cola GB lists caffeine flavouring for standard Diet Coke, while its Diet Coke No Caffeine is a separate variant.
If you are avoiding caffeine, choose a pack explicitly labelled ‘No Caffeine’ or ‘Caffeine Free’ and check its description.
-
Overlooking the quantity in a multipack
Tesco Groceries lists diet-cola cans and bottles in different pack sizes. A listing image alone may not make the total quantity clear.
Read the pack count and individual volume before ordering, particularly when comparing cans with large bottles.

Questions about diet fizzy drinks
Does zero sugar mean caffeine-free?
No. Coca-Cola GB and Pepsi UK list caffeine or caffeine-containing flavourings for standard Coca-Cola Zero Sugar and Pepsi Max. If you are avoiding caffeine, select a specifically named variant such as Diet Coke No Caffeine or Pepsi Max No Caffeine.
What should I choose when cutting down on sugary fizzy drinks?
Check the exact drink’s sugars per 100ml and choose a sugar-free or diet variant if that meets your aim. NHS guidance names water, lower-fat milk and sugar-free, diet or no-added-sugar drinks as alternatives to sugary fizzy drinks; the nutrition panel helps you distinguish a named variant from its regular counterpart.
How do I choose a multipack for delivery?
Check the full variant name, can or bottle count, individual volume and total quantity before placing the order. Tesco Groceries lists diet-cola drinks in different formats, so confirm that the specific pack fits your household’s needs and storage space.
Why check ingredients on a diet or zero-sugar drink?
Diet and zero-sugar describe the drink’s sugar-related variant, not every ingredient. Reviewed Coca-Cola GB and Pepsi UK products list sweeteners and statements that they contain a source of phenylalanine; check the current listing and delivered label if a particular ingredient or statement matters to you.
