Hosts keeping sugar to a minimum
Look for an explicit sugar-free or zero-sugar claim on the exact flavour you plan to serve. Then check the nutrition panel rather than relying on a brand name or a “no added sugars” claim.
Who is choosing the drinks?
The useful starting point is who will be offered a can, not simply how many cans to buy.
Hosts choosing between can sizes
Compare caffeine per can before choosing a case. Red Bull states that Sugarfree contains 80 mg in a 250 ml can; Monster Energy lists 150 mg in a 500 ml Monster Ultra can. A larger can is a different caffeine choice, not merely a different serving size.
Hosts with mixed-age or caffeine-avoiding guests
Keep caffeine-free drinks available rather than assuming a sugar-free energy drink suits everyone. Check the pack warnings and any age restrictions that apply where and when you buy.
What should you check?
Choose the sugar claim first, then compare the caffeine in the can guests would actually drink. Flavour and case size matter once those checks fit the party.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar claim | Read the exact pack claim and sugar figure on the nutrition panel. The nutrition-claim conditions published by legislation.gov.uk distinguish “no added sugars” from a sugar-free claim; the former does not, by itself, establish the latter. | “I want to offer drinks that match a sugar-free party brief, whichever flavour I choose.” |
| Caffeine per can | Compare the amount in the whole can, not just its volume. Red Bull lists 80 mg per 250 ml Sugarfree can; Monster Energy lists 150 mg per 500 ml Monster Ultra can. Account for other caffeine consumed that day. | “Some guests may prefer a smaller can, while others may choose a 500 ml serving. I want them to be able to see the caffeine amount before taking one.” |
| Guest suitability | Read the product warnings and provide a caffeine-free choice. For purchases involving under-16s, check the nation, purchase date and retailer requirements: the UK Government has announced an England-specific ban on sales of high-caffeine energy drinks to under-16s from April 2027. | “Children or guests avoiding caffeine may attend, so the drinks table needs an option other than energy drinks.” |
| Flavour and pack | Check the named variant, can size and number of cans. Confirm the sugar claim for that flavour; products from one brand need not have the same ingredients or claim. | “I want a flavour guests will choose, in a pack size that fits the gathering, without assuming every variant meets the sugar brief.” |
Shopping mistakes to avoid
-
Treating “no added sugars” as another way to say “sugar-free”
The claims describe different conditions. Under the nutrition-claim conditions published by legislation.gov.uk, “no added sugars” concerns sugars or other foods added for sweetening; it does not alone tell you the drink’s total sugar content.
If the party brief is sugar-free drinks, check for that claim on the exact pack and read its nutrition panel.
-
Counting cans without comparing caffeine
Red Bull’s 250 ml Sugarfree can contains 80 mg caffeine, while Monster Energy lists 150 mg for a 500 ml Monster Ultra can. A case of cans tells you how many servings you have, not how much caffeine is in each serving.
Check caffeine per whole can and leave caffeine-free drinks available, particularly when guests may also have had tea, coffee or other sources of caffeine.
-
Assuming every flavour from a brand meets the brief
Relentless lists sucrose and glucose in the ingredients for its Cherry drink. A brand name therefore cannot stand in for the claim and ingredients on a particular variant.
Check the flavour, sugar claim, nutrition panel and ingredients on the product you intend to serve.
-
Applying an announced age rule across the UK today
The UK Government has announced a ban on sales of high-caffeine energy drinks to under-16s in England from April 2027. That announcement is not a present-day, UK-wide rule.
Check requirements for the nation and date of purchase, along with the retailer’s current age-verification policy. Do not plan energy drinks as the only refreshments for an under-16 party.
Relevant brand ranges
A range name can help narrow the choice, but use the exact variant’s label for the final sugar and caffeine checks.
Red Bull
Red Bull Sugarfree is a smaller-can reference for a sugar-free energy drink: Red Bull lists 80 mg caffeine per 250 ml can.
- Red Bull says its sugar-free products use non-caloric sweeteners instead of sugars.
- Sugarfree still contains caffeine; check the particular edition and its pack warnings before serving it.
Monster
Monster Energy lists 0 g sugar and 150 mg caffeine for its 500 ml Monster Ultra can, offering a larger-can reference than Red Bull Sugarfree 250 ml.
- Monster Energy also lists those figures for its 500 ml Ultra Black variant, giving hosts a named flavour to compare.
- Check the exact Ultra variant and pack: figures for one flavour should not be assumed for every Monster drink.
Relentless
Relentless needs a variant-by-variant label check for a party focused on sugar-free drinks.
- A Relentless promotion named a Zero Sugar Raspberry variant; use the current pack claim when considering any such option.
- Relentless lists sucrose and glucose in its Cherry drink, so Cherry should not be selected on the assumption that the whole brand is sugar-free.
Lucozade
Lucozade Zero is described by Lucozade as a zero-sugar soft-drink range, which may suit a drinks table alongside energy drinks.
- The Zero range provides a separately labelled zero-sugar soft-drink option.
- Lucozade Alert is a separate caffeine-containing range. Do not transfer the Zero range’s sugar claim to an Alert drink; check its exact pack.

Frequently asked questions
Is “no added sugars” the same as “sugar-free”?
No. The nutrition-claim conditions published by legislation.gov.uk treat them as different claims: “no added sugars” addresses sugars or other foods added for sweetening, not the drink’s total sugar content by itself. For a sugar-free party choice, read the exact pack claim and nutrition panel.
Does zero sugar mean less caffeine?
No: a sugar claim does not tell you the caffeine dose. Monster Energy lists 0 g sugar and 150 mg caffeine in a 500 ml Monster Ultra can, while Red Bull states that its 250 ml Sugarfree can contains 80 mg caffeine. Compare the amount per whole can for the variants you are considering.
What if under-16s are coming to the party?
Provide drinks other than energy drinks and check the applicable rules when purchasing. The UK Government has announced that sales of high-caffeine energy drinks to under-16s in England will be banned from April 2027; that is an England-specific future change, not a current UK-wide rule. Retailer age-verification requirements should also be checked at the time of purchase.
What should I offer guests who are avoiding caffeine?
Include a caffeine-free option rather than relying on sugar-free energy drinks. The European Food Safety Authority assesses caffeine intake from all sources, so the caffeine in a can is only part of what a guest may consume during the day. Read pack warnings when planning drinks for pregnant guests.
Can I substitute Lucozade Alert for Lucozade Zero?
Do not assume the two ranges have the same sugar or caffeine profile. Lucozade describes Zero as a zero-sugar soft-drink range and describes Alert separately as containing caffeine. Check the exact Alert pack’s sugar claim and nutrition information before choosing it for a sugar-free drinks table.
