Students stocking a shared kitchen
Separate cans or bottles make it easier for housemates to take individual drinks. If everyone expects to share one larger bottle, check its volume and what the label says about storage after opening.
Who is choosing these drinks?
Students considering caffeine timing
Check the caffeine declaration for the exact drink and container size. Northern Care Alliance NHS Foundation Trust notes that caffeinated drinks, including energy drinks, may affect sleep when consumed late in the day.
Buyers comparing sugar variants
A regular drink and a zero-sugar variant need separate label checks. Ocado lists 0g sugars per 500ml for Monster Ultra Zero Sugar, but 19g per 500ml can for the reviewed Relentless Origin product.
What should you check before buying?
Separate cans or bottles
Choose when: Several adults will use the drinks, or individual containers are easier to store and carry.
Bear in mind: A pack’s total volume is not one serving; check the caffeine and sugars for the particular variant.
A larger single bottle
Choose when: A bottle smaller than 2 litres meets the need and there is space to store it as its label directs.
Bear in mind: Sainsbury’s Groceries lists a 900ml Lucozade Energy bottle, not a 2-litre one; check its own opened-storage instructions.
A 2-litre fizzy drink
Choose when: The requirement is a large shared fizzy drink rather than specifically an energy drink.
Bear in mind: Tesco Groceries lists 2-litre soft drinks in its search results; check the exact product’s ingredients and nutrition panel rather than assuming it is an energy drink.
| Priority | What to check | Your needs |
|---|---|---|
| Format | Check the product category, volume of each container and number of containers. Four 500ml cans total 2 litres but are not one 2-litre bottle. | I need to know whether the shop calls for one shared bottle or separate drinks for housemates. |
| Caffeine | Read the caffeine amount in mg per 100ml, the container volume and any high-caffeine warning. For covered drinks containing more than 150mg caffeine per litre, the Department of Health and Social Care says the warning and per-100ml amount are required. | If I might drink one later in the day, caffeine timing matters: Northern Care Alliance NHS Foundation Trust says late consumption may affect sleep. |
| Sugars | Compare the exact flavour and variant using sugars per 100ml and per container. Ocado lists 0g per 500ml for Monster Ultra Zero Sugar and 19g per 500ml for Relentless Origin. | A zero-sugar name on one variant does not tell me the sugar content of another drink from the same brand. |
| Opened storage | Read the instructions on the bottle you buy and check that it will fit in the fridge if refrigeration is required. Ocado’s Lucozade Energy Orange listing says to refrigerate after opening and drink within four days. | For a drink that will be shared slowly, I need an opened-storage window that works for our kitchen. |
What can go wrong with the format?
-
Assuming any 2-litre fizzy drink is an energy drink
Tesco Groceries’ reviewed 2-litre search results include fizzy soft drinks, while its energy-drink range lists smaller formats. Bottle size does not establish the product category or its caffeine content.
Check the category, ingredients, caffeine declaration and nutrition panel on the exact listing.
-
Reading a multipack’s total volume as a serving
A 4 x 500ml pack totals 2 litres, but contains four separate cans. The amount in one can is the useful starting point when checking its label.
Compare container size and the stated caffeine and sugars per container, not just the pack total.
-
Assuming all variants have the same sugars
Ocado lists 0g sugars per 500ml for Monster Ultra Zero Sugar and 19g per 500ml can for Relentless Origin. The precise variant changes the comparison.
Use the per-100ml and per-container figures for the flavour and pack being purchased.
-
Leaving caffeine timing out of the move-in plan
Northern Care Alliance NHS Foundation Trust notes that caffeinated drinks taken late in the day may affect sleep.
Check the caffeine label before buying and keep water or other non-caffeinated drinks available during the move.
Which brand ranges are relevant?
Red Bull
Tesco Groceries and Sainsbury’s Groceries list 250ml cans in multipacks.
- Individual cans offer a smaller container than the reviewed 500ml options.
- Those listed multipacks do not provide a single 2-litre bottle.
Monster
The reviewed UK listings include 500ml cans and multipacks, including an Ultra Zero Sugar variant.
- Ocado lists 0g sugars per 500ml for its reviewed Monster Ultra Zero Sugar product.
- Check the exact variant and can label; the reviewed formats are separate cans rather than one 2-litre bottle.
Relentless
Tesco Groceries and Sainsbury’s Groceries list Origin in 500ml cans and 4 x 500ml packs.
- The four-can pack totals 2 litres across sealed individual cans.
- Ocado lists 19g sugars per 500ml can for the reviewed Origin product; do not treat the pack as a zero-sugar variant.
Lucozade Energy
Sainsbury’s Groceries lists a 900ml bottle alongside smaller multipack formats.
- The listed 900ml format offers a larger single bottle than the reviewed can sizes.
- It is still short of 2 litres. Check the exact bottle’s sugars, caffeine and opened-storage directions; Ocado’s reviewed Orange product instructs refrigeration after opening and consumption within four days.

Common questions
Can I count on finding a 2-litre energy-drink bottle for a move-in shop?
Not in the Tesco Groceries and Sainsbury’s Groceries energy-drink ranges reviewed: they list smaller bottles, cans and multipacks. Tesco’s reviewed 2-litre search results include fizzy soft drinks, so check the category as well as the bottle size.
Are energy drinks subject to one age rule throughout the UK?
Do not assume a single UK-wide rule from a retailer’s age restriction. In July 2026, the Department of Health and Social Care announced a proposed England ban on sales of drinks containing more than 150mg caffeine per litre to under-16s from April 2027, subject to Parliamentary approval. Separately, Ocado marks its reviewed Monster and Relentless products as restricted to customers aged 18 or over under its retailer policy.
Which caffeine figure should I compare?
Compare caffeine in mg per 100ml alongside the size of the can or bottle. The Department of Health and Social Care states that covered drinks containing more than 150mg caffeine per litre must carry a high-caffeine warning and declare caffeine per 100ml; check the label of the exact variant you intend to buy.
How long can a larger Lucozade Energy bottle be kept once opened?
Follow the instructions on the exact bottle. Ocado’s reviewed Lucozade Energy Orange product says to refrigerate after opening and drink within four days; do not assume another flavour or pack has the same directions.
Should energy drinks be the only drinks available on move-in day?
Keep water or other non-caffeinated drinks available too. Northern Care Alliance NHS Foundation Trust notes that dehydration can worsen tiredness and that caffeinated drinks taken late in the day may affect sleep.
