So… Is SodaStream Cheaper?
✅ Cheaper than branded drinks
You’re saving 50% or more compared to Coca-Cola and other big brands because the cost of owning SodaStream is lower overall.
✅ Comparable to budget supermarket drinks
But with a major advantage, the ongoing cost of SodaStream can actually be competitive with budget supermarket drinks.
Why SodaStream Still Wins
Even when supermarket cola looks slightly cheaper on paper, SodaStream cost is balanced with extra benefits:
1. Custom Strength & Flavour
Make drinks exactly how you like them — stronger, weaker, more fizz, while keeping your total SodaStream cost low.
2. Massive Variety
Switch flavours anytime (cola one day, blue raspberry the next), all without worrying about increasing your SodaStream cost.
3. Less Plastic Waste
No more hauling bottles home or filling the recycling bin, which helps lessen the environmental cost of your SodaStream machine.
4. Better Value Over Time
Buying in bulk (like twin packs) brings your cost down to just 50p per litre, so your cost per drink continues to drop.
