FAQs
Does Waterdrop offer free shipping?
Yes, as standard, all orders to the mainland UK will include free standard delivery with no minimum spend, which should arrive in 2 - 4 business days. If you want to receive your order sooner, you can also pay £3.99 for express shipping, which will arrive in 1 - 2 business days, at the checkout. You'll be sent tracking details once your order has been dispatched.
What is Waterdrop Rewards?
Waterdrop Rewards allows customers to earn points on their purchase, which can be redeemed for discounts or free items at the checkout. Its free to join the programme - simply create an account - and members will earn 10 points for every £1 they spend. Every 1000 points is worth a £2 discount, and points can be spent on unique codes or offers through the members hub.
Waterdrop updates its members offers regularly, bringing you both sitewide and specific product discounts. Selected products such as filters and water jugs may also be purchasable with points: for example, you can get a free G3-N2RO filter for 44,995 points.
The brand often lowers the point price of select discounts for a limited time, too, letting you get your discount codes sooner if you catch the right deal. For example, you can always earn a coupon for £20 off with 10,000 points, but occasionally, we've seen the likes of 25% off for the same points total.
What is the Waterdrop returns policy?
Waterdrop customers can send items back to the brand for any reason in exchange for a refund, so long as they do so within 30 days of receiving their order. To qualify, you will need to disassemble and repackage your items. You will also have to arrange and cover the cost of your own return shipping.
The brand will occasionally allow returns after 30 days, but these will incur a 10% restocking fee which will be deducted from your refund total. To start the process, you'll need to get in touch with the brand's customer service team, who will provide further instructions within 24 hours.

How we source voucher codes
The codes listed on each vouchers page on Tom’s Guide have been sourced by our dedicated vouchers team, who find the latest codes through the web and our relationships with retailers and affiliate networks. Each page is updated every few days to include up-to-date offers and ways to save, and our London-based commercial team uses our connections with retailers to source exclusive codes directly from some of the biggest brands on the market.
How we test voucher codes
Every voucher code on Tom’s Guide has been tested by our offers team, based in Cardiff, to make sure they work before we upload them. The codes on Tom’s Guide can be used for a wide range of savings, covering student discounts, free shipping deals, and site-wide or product-specific savings.
We want to make sure every voucher is ready to use whenever someone visits one of our pages, so we don’t include any user-specific or one-time use codes. Each offer also includes as much information as we can find on its terms and conditions to keep things clear, and any applicable expiry dates will be listed next to the offer details. You can view the full list of terms and conditions by clicking the corresponding text below the main offer text and expanding the section.
What to do if a voucher code doesn’t work
Although we work hard to only include tried and tested vouchers on our pages, sometimes codes can expire or terms and conditions can be changed before we have a chance to update the code or our pages. If your discount isn’t being applied at the checkout, there are a number of things you can do.
First, check you meet any listed requirements such as multibuy offers, minimum spends, or product-specific deals. For example, you may need to buy 3 items to receive your discount, or your code may only be applicable to orders with certain models (i.e. 10% off specific smartphones). If you need to review the details of your chosen deal, click the text that reads “View terms and conditions” below the main text.
If you are still experiencing issues applying your discount, don’t worry - our team is on hand to help. Just email coupons.tomsguide@futurenet.com and include information on the code you tried to redeem and which of our pages it was listed on. A member of our team will be in touch to offer support as soon as they can.
How we make money
Tom’s Guide makes money from vouchers on a commission basis. We have agreements with every retailer that has a vouchers page for, and for every order placed using one of our codes, we earn a portion of the order total back in commission from that retailer.
Using this model means all of our profits are paid for by the retailers we partner with, and we do not pass any costs on to our users. Using one of our vouchers will never cost you anything - you’ll only pay for the discounted products you’re looking to buy, so you can rest easy knowing you get exactly what it says on the tin.
