About Sodastream
SodaStream is a home sparkling water brand originally founded in the UK in 1903 and later rebuilt around the modern countertop fizzy-water maker. Today it is owned by PepsiCo and manufactured across international sites with a major plant in Israel. The UK site sodastream.co.uk sells the full countertop range (Terra, Art, Spirit, Duo, E-Terra and the Gaia), plus reusable bottles, CO2 cylinders in exchange and buy-back schemes, and a wide range of concentrated flavour drops and syrups (classic fizzy-drink flavours, fruit, tonic, energy and healthier zero-sugar options). SodaStream is pitched as a more sustainable way to enjoy sparkling water at home — each reusable bottle and returned CO2 cylinder keeps many single-use plastic bottles out of circulation. UK customers can swap empty cylinders via the Gas Exchange service (returning old cylinders by post or in-store at major retailers) rather than buying new.
💡 Money-saving tips for Sodastream
- ✓SodaStream bundles (machine + extra bottle + CO2 + flavour pack) are almost always better value than buying each item separately, especially for first-time buyers. The biggest discounts land during Black Friday / Cyber Monday, Boxing Day, New Year health campaigns and the summer sparkling-water push, with up to 30-40% off starter kits. Sign up to the newsletter for a welcome discount and early access to bundle deals. The Gas Exchange scheme is the cheapest way to keep your CO2 topped up — swap empties rather than buying new cylinders every time. Subscribe & Save options on flavour drops and bottles give a recurring discount. The refurbished / outlet section occasionally lists previous-generation machines with full warranty at a reduced price. Pair a promo code with a starter bundle to maximise savings on the first purchase.
❓ Frequently asked questions about Sodastream
How does a SodaStream machine work?
You fill a reusable bottle with cold tap water, screw it into the machine and press the button to release CO2 from the cylinder, which carbonates the water. You can add a flavour drop afterwards if you want a fizzy drink. One CO2 cylinder typically makes around 60 litres of sparkling water, depending on preferred fizz level.
Can I exchange empty CO2 cylinders?
Yes. SodaStream runs a Gas Exchange scheme across the UK. You can order replacement cylinders online and return the empty ones with the pre-paid label, or swap them in person at many major supermarkets and homeware retailers. Exchanging is significantly cheaper than buying new cylinders each time.
Are SodaStream bottles dishwasher safe?
SodaStream's newer Dishwasher Safe (DWS) bottles are marked as dishwasher-friendly on the top rack. Older classic bottles should be washed by hand in warm soapy water to preserve the plastic and the pressure rating. Check the small symbol printed on the base of each bottle before washing.
What's the warranty on SodaStream machines?
Most SodaStream machines come with a 2-year manufacturer warranty in the UK, covering manufacturing defects. Register your machine after purchase to activate the warranty. Normal wear and tear, misuse or damage to the CO2 cylinder are not covered.
