Car boot sellers offering sealed soft drinks
Individual cans let you offer separate zero-sugar and caffeine-free choices without confusing the two. Keep the original labels visible so visitors can check the exact drink.
Who is choosing these drinks?
Visitors avoiding sugar but not necessarily caffeine
Coca-Cola Great Britain lists 0 g sugars per 100 ml for Coca-Cola Zero Sugar, and Pepsi UK lists the same for Pepsi MAX. Both standard variants list caffeine in their ingredients.
Visitors avoiding both sugar and caffeine
Look for a specifically identified caffeine-free, no-sugar variant. Pepsi UK lists 0 g sugars per 100 ml for Pepsi MAX No Caffeine; its published ingredient list does not include caffeine.
What should you check?
Decide which labelled choices you want to offer, then check the exact cans and pack format before buying.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Read the sugars figure per 100 ml on the nutrition label. Coca-Cola Great Britain and Pepsi UK each list 0 g sugars per 100 ml for their named Zero Sugar or MAX variants. | I want a cola option for visitors avoiding sugar, without relying on the word “diet” alone. |
| Caffeine | Check the exact variant, not just its sugar claim. Coca-Cola Zero Sugar and Pepsi MAX list caffeine; Pepsi MAX No Caffeine is a separately named variant. | Some visitors may want no caffeine as well as no sugar, so I need to identify that choice clearly. |
| Ingredients | Read the sweetener ingredients and phenylalanine declaration on the can. The named Coca-Cola and Pepsi zero-sugar products publish these details on their UK product pages. | I want visitors to be able to inspect the exact label for their own dietary requirements. |
| Serving format | Check the number of cans and volume per can. Tesco Groceries lists both 8 × 330 ml and 24 × 330 ml diet or zero-sugar cola multipacks. | Sealed individual portions would be easier to set out than pouring drinks at the refreshment table. |
Common selection mistakes
-
Assuming zero sugar means caffeine-free
The standard Coca-Cola Zero Sugar and Pepsi MAX ingredient lists include caffeine, according to their UK brand pages.
If caffeine avoidance matters, choose a variant specifically labelled caffeine-free and check that exact can.
-
Overlooking the rest of the ingredients
The named zero-sugar variants list sweeteners and carry a source-of-phenylalanine declaration. A sugar figure alone does not describe every ingredient.
Keep drinks in their original cans so visitors can read the ingredient and label information themselves.
-
Assuming refreshment sales need no local checks
For a new food business, the Food Standards Agency says registration with the local authority is required at least 28 days before trading or food operations start. Whether an arrangement is a food business depends on the activity.
Check your plans with the relevant local authority and event organiser before selling. Event requirements are local: Cheshire West and Chester Council, for example, says a car boot sale may need authorisation or a market licence.

Questions about car boot sale cola
Is zero-sugar cola automatically caffeine-free?
No. Coca-Cola Great Britain lists caffeine flavouring in standard Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in Pepsi MAX. If caffeine avoidance matters, check for a specifically named caffeine-free variant; Pepsi MAX No Caffeine is one no-sugar example.
Can I use an online listing to check ingredients?
Use the listing to identify a product, then read the exact pack label. Tesco Groceries advises this because food ingredients and nutrition information can change.
Do I need to register before selling canned cola?
If you are starting a food business, the Food Standards Agency says you must register with your local authority at least 28 days before trading or food operations start. Ask the relevant authority whether your planned activity falls within that requirement rather than assuming every personal refreshment arrangement does.
Does a car boot sale need local permission?
Check with the organiser and the local authority where the sale takes place. Requirements are local: Cheshire West and Chester Council says a car boot sale in its area may need authorisation or a market licence, which should not be treated as a rule for every UK event.
