Get a 50% discount on your next CO2 exchange bought from sodastream.co.uk by returning your spare CO2 cylinders!

We’re all about recycling at SodaStream and we’re always looking at ways to make a difference. Simply send us one or more of your empty SodaStream CO2 cylinders and we’ll send you a 50% off voucher in return – helping you stay sparkling for less.

A great way to stay sparkling and save money

We make it easy for you to return your used CO2 cylinders. In a few simple steps you will be able to make some space in your kitchen and save money as well.

We are unable to refund cylinders that have not been purchased directly from us, but we can offer you discount codes if you do return them to us. The discount codes can be used against future orders of CO2 refill cylinders purchased on SodaStream.co.uk.

How it Works

If you have one or more empty SodaStream cylinders, that fit a current sparkling water maker, you’re eligible! Simply follow the steps below:

• Print the online form found at: sodastream.co.uk/gasbuyback
• Complete the form.
• Package up your empty CO2 cylinders, along with the form, into suitable packaging.
• Drop off at your nearest Collect+ store
• You will get a voucher code for 50% off a single CO2 exchange (excluding deposit) for every empty CO2 cylinder that we receive from you*

**Vouchers can only be redeemed as sodastream.co.uk - only one voucher can be used per purchase and cannot be used in conjunction with any other discount. Vouchers can only be redeemed against CO2 refills/exchanges and not any CO2 plans.

Why it Matters

Aside from helping the environment, all CO2 cylinders can be refilled for further use and should be returned to the supplier. Please do not place CO2 cylinders in your general waste bin as we can recycle these responsibly instead.
