FAQs

Is Sodastream worth it?

That honestly depends on the reasons you buy it. If you are buying it solely to save pennies against the cheapest supermarket own-brand sparkling water, then you won't save large amounts. However, if you drink premium brands (like San Pellegrino, Lipton and Pepsi) or want to reduce your plastic waste, it is absolutely worth it. This is because a cylinder makes up to 60 litres and with syrup you're only paying around 75p – 95p per litre of flavoured soda which is cheaper than buying from the supermarket.

Where can I get Sodastream refills?

You can get SodaStream gas refills (exchanges) at most major UK supermarkets at the customer service desks. You can also order them from Sodastream themselves or online at Amazon.

Where can I dispose of Sodastream canisters?

There are two main options: either exchange the cylinder for a full one or bin it permanently.

If you just need more gas, do not throw the cylinder away. You trade your empty one for a full one and pay a discounted price at Sodastream or supermarkets like Sainsbury's.

If you just want to get rid of the cylinders, you can't put them in your normal recycling bin, but you can return them directly to Sodastream for free.

Is Sodastream healthier?

Kind of, but it depends entirely on what you were drinking before, because if you use SodaStream's official syrups, they typically contain significantly less sugar than the canned versions. You can also control your ratios and put in half the amount to get the flavour with half the sugar.

Also, carbonated water creates carbonic acid, which is less acidic than fruit juice or canned Pepsi (this doesn't mean it's good for teeth, just slightly better than canned drinks)

Sodastream Saving Tips

Always Exchange: This is the single most important rule. A brand new gas cylinder costs roughly £25. But if you return your empty cylinder, a refill exchange only costs around £13.

Student Discount: Great news for students who want to save on soda, you can get 15% off your order by verifying your student status with Student Beans.

Blue Light Discounts: If you have a Blue Light Card, check your app. SodaStream often offers exclusive discounts for key workers, often between 10-20%.

Shop the Sale Page: Sodastream has a Sales & Offers page accessed via a link at the bottom of their home page, where you can get offers on bundles and refills.

How we source coupon codes

The coupons you’ll find on Tom’s Guide have been sourced by our dedicated coupons team, who use the web, our relationships with retailers, & our affiliate networks to find the latest codes. The offers on each coupon page are updated every few days to ensure we feature the freshest ways to save, and our commercial team (based in London) also sources exclusive codes and sales info directly from some of the biggest retailers around.

How we test coupon codes

All the coupon codes we list on our pages have been tested by our deals & offers teams to check they work as intended before they’ve been uploaded. You’ll find a wide range of coupons on Tom’s Guide, including free shipping offers, student discounts, and savings on various kinds of products.

To ensure that all listed codes are available to use, we don’t include any one-time use or user-specific coupons. We also provide as much information as we can to keep things as clear as possible - any expiry dates or terms & conditions will be listed alongside the code. Look for the ‘Terms & Conditions’ text - you’ll be able to click this to expand this section for more details.

What to do if a coupon code doesn’t work

We take care to only list tried & tested coupons on our pages, so all codes should be active and confer the listed discount or deal. However, although we keep up to date with expiry dates and any terms & conditions, sometimes retailers change these before we can update our pages.

Should a coupon fail to work as expected, check you meet any listed requirements. These can include minimum spends, multibuy offers, or product-specific promotions (i.e. 10% off selected tablets). You can view all associated requirements by clicking “View terms and conditions” below your code.

If this does not solve your issue, you can contact our customer service team by emailing coupons.tomsguide@futurenet.com. Make sure to let us know which coupon you were trying to use and which page this was listed on, and we’ll be in touch to help as soon as possible.

How we make money 

Tom’s Guide makes money from coupons through a commission-based model. We have agreements in place with each retailer on our site - for every purchase made using one of our coupons or deals, we earn a small percentage of the order total back in commission.

Thanks to this model, we can save our customers money without charging them a thing. You won’t pay a penny to get the discounts listed on our pages, so whichever code or deal you choose, you’ll get exactly what it says on the tin.
