Regular buyers planning a budget shop
If you buy multipacks regularly, compare their total volume and check whether an advertised Clubcard offer applies to you. Tesco Groceries lists offers with conditions that may affect the choice at checkout.
Who is choosing a multipack?
Shoppers comparing sugar content
If you want a zero-sugar variant, check its caffeine separately. Monster Energy UK states that Absolutely Zero contains 0 g sugar and 160 mg caffeine per 500 ml can.
Shoppers who prefer smaller cans
A 250 ml can may suit the amount you intend to drink at one time. Red Bull UK states that its Original 250 ml can contains 80 mg caffeine; check the exact variant when comparing multipacks.
What matters when choosing?
Start with pack volume and offer conditions, then compare the sugar and caffeine stated for the exact can you intend to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check the number of cans, volume per can and total pack volume. Confirm that any Clubcard offer applies when you shop. | I want a multipack with cans I will use, rather than choosing by pack count alone. |
| Sugar | Read the sugar amount for the exact variant and can size. Red Bull UK states that Original contains 27 g sugars per 250 ml can; Monster Energy UK states that Absolutely Zero contains 0 g per 500 ml can. | If I am choosing a sugar-free version, I need to distinguish it from the brand’s Original drink. |
| Caffeine per can | Compare the stated amount per can, not just can volume. Red Bull UK lists 80 mg in its Original 250 ml can; Monster Energy UK lists 160 mg in an Absolutely Zero 500 ml can. | A larger can may contain a different amount of caffeine in the portion I actually drink. |
| Who will drink it | Read the on-pack caffeine warning. The NHS advises no more than 200 mg caffeine a day during pregnancy, including caffeine from other food and drinks. | If the multipack is for someone who needs to limit caffeine, I need to consider the exact drink and other caffeine sources. |
What should you avoid overlooking?

Treating a Clubcard offer as available to everyone
Tesco Groceries displays Clubcard conditions on some energy-drink multipacks. An offer may not apply to every shopper or remain available when they check out.
Confirm your eligibility and the offer conditions before comparing packs.
-
Choosing a larger can on volume alone
Red Bull UK lists 80 mg caffeine in its Original 250 ml can, while Monster Energy UK lists 160 mg in an Absolutely Zero 500 ml can. The amount in one can matters if you drink it in one sitting.
Compare caffeine per can alongside the amount you intend to drink.
-
Assuming sugar-free means caffeine-free
Monster Energy UK states that Absolutely Zero contains 0 g sugar but still contains 160 mg caffeine per 500 ml can.
Check sugar and caffeine as separate figures on the exact variant.
-
Overlooking the age-related rules in England
The Department of Health and Social Care announced an England-only ban on sales of high-caffeine energy drinks to under-16s from April 2027. Its announced threshold is more than 150 mg caffeine per litre for drinks other than tea or coffee; the measure is not a current UK-wide rule.
If buying for a young person, check the drink’s label and the applicable rules at the time and place of purchase.

Common questions
How should I compare multipacks with different can sizes?
Compare each pack’s total volume as well as its can count, then check whether an advertised Clubcard offer applies to you. That prevents an eight-pack of 250 ml cans and a four-pack of 500 ml cans from looking different in volume when both contain 2 litres.
Does sugar-free mean an energy drink has less caffeine?
No: sugar and caffeine are separate figures. Monster Energy UK states that Absolutely Zero contains 0 g sugar and 160 mg caffeine per 500 ml can, so check both figures for the exact drink.
Why does caffeine per can matter?
It shows the amount in the can you may drink at one time. Red Bull UK states that its Original 250 ml can contains 80 mg caffeine, while Monster Energy UK states that its Absolutely Zero 500 ml can contains 160 mg; those figures apply to the named variants, not every drink from either brand.
Is there an age restriction on high-caffeine energy drinks in England?
The Department of Health and Social Care has announced an England-only ban on sales to under-16s from April 2027; it is not a current UK-wide rule. The announced measure covers drinks other than tea or coffee containing more than 150 mg caffeine per litre and is intended to apply to shops, vending machines and online sales. Check the applicable position when buying.
