Save more with Waterdrop Rewards
If you're a regular buyer of filters or thinking of upgrading, Waterdrop Rewards is worth it. Spend a pound, get 10 points. Then use those points for discounts or free stuff. For example, 500 points knocks 5% off orders over £100, 1,000 points is £2 off, all the way up to 20,000 points for 20% off. And if you save up 14,000 points, you get a free G3-N1CF filter. Points do expire if you don't order for a year, so it's good to keep buying when you need filters. Tip: if you're planning to buy something big like an RO system, wait until you've racked up enough points for a nice discount. Also, you can refer a friend and both get 25% off orders over £200, but you can only use one code per order, so use the one that saves you the most.

Money saving tips at Waterdrop
Newsletter deal
Sign up to the Waterdrop newsletter and you'll get 10% off your first order. If you're buying a filter system or a replacement cartridge for the first time, that's an easy saving. It can also take a decent chunk off a bigger basket, so it's worth doing before checkout.
Rewards points
If you buy filters regularly, Waterdrop Rewards is worth a look. You earn 10 points for every £1 spent, then swap them for money off or free products. The rewards ladder is a bit odd, but useful: 500 points gets 5% off orders over £100, 1,000 points gets you £2 off, 10,000 points is worth £25 off, and 20,000 points gives you 20% off. Just do not leave your points sitting there too long, as they expire after a year of inactivity.
Refer a friend
Waterdrop's referral scheme gives both people 25% off, which is handy if you're placing a larger order over £200. Your friend has to be a new customer and use your unique referral link, and you can only use up to 5 coupons per user. If someone you know is already eyeing up a water filter, this is an easy one to pass along.
Free delivery
All Waterdrop orders come with free UK standard delivery, with no minimum spend. So unless you really need it quickly, there's not much reason to pay extra. Express delivery costs £3.99 for 1-2 business days, but for most orders the free option does the job.
Special offers
Keep an eye on Waterdrop's special offers page and seasonal events like the Spring Refresh Event, Waterdrop Daily Deal, and Autumn Deal. We've seen discounts of up to £300 during these promos, so it can be worth waiting if you're not in a rush. Sale items and some product exclusions may apply, so always check the small print before you buy.
Frequently asked questions about Waterdrop
How do I use/apply a Waterdrop discount code?
Using a Waterdrop discount code is easy. Here’s how we do it at LatestDeals:
- Head to LatestDeals and pick a Waterdrop discount code that works for what you want.
- Click the orange 'See Code' button—the code pops up on screen, so copy it.
- You’ll be redirected to Waterdrop’s website in a new tab.
- Shop for your water filter, replacement cartridge, or whatever you need, and add it to your basket.
- Go to checkout. Look for the box labelled 'Discount code or gift card'.
- Paste your code in there and click 'Apply'.
- Your discount should show straight away. Then just pay and you’re done.
What can I do if my Waterdrop code isn’t working?
It’s frustrating when a code doesn’t work, but there are a few things we check first:
- Expired? Codes have expiry dates, so make sure yours is still valid.
- Already used? You can only use a code once per account.
- Minimum spend? Some codes, like the referral 25% off, need a £200 order. Others might exclude sale items or gift cards.
- Only one code per order – Waterdrop doesn’t let you stack codes, so if you’ve already applied another, remove it first.
- Typo? Copy and paste the code exactly – no extra spaces.
If it still won’t go through, try a different code from LatestDeals. And if nothing works, contact Waterdrop’s customer service – they’re pretty helpful.
Can I use more than one Waterdrop promo/voucher code on the same order?
No, Waterdrop only lets you use one discount code per order. Our team has checked – you can’t combine a newsletter code with a referral code, for example. So pick the one that gives you the biggest saving.
Is there a Waterdrop discount for first orders / new customers?
Yes, there is. If you sign up for the Waterdrop newsletter, you get 10% off your first order. That’s a solid deal. Also, if a friend refers you, you get 25% off orders over £200 – but you can only use one code, so go with whatever saves you more.
What is the Waterdrop Rewards loyalty program?
We think Waterdrop Rewards is worth knowing about. You earn 10 points for every £1 you spend. Then you can swap points for discounts or free stuff:
- 500 points = 5% off orders over £100
- 1,000 points = £2 off
- 10,000 points = £25 off
- 20,000 points = 20% off
Or you can save up 14,000 points for a free G3-N1CF filter. Just remember, points expire if you don’t order for a year. So if you buy filters regularly, it’s a nice bonus.
Does Waterdrop offer free delivery?
Waterdrop gives free UK standard delivery on every order – no minimum spend. That’s great if you only need a small item. If you’re in a hurry, express delivery costs £3.99 for 1-2 business days. Just note they don’t deliver to BFPO, Channel Islands, or Ireland.
What is the Waterdrop returns policy?
You have 30 days from when you receive your item to return it. If it’s faulty, Waterdrop pays the return postage. Otherwise, you’ll need to cover the shipping cost. No restocking fee within 30 days – after that, there’s a 10% fee. So it’s best to decide quickly.

About Waterdrop
Waterdrop is a UK retailer specialising in water filtration products for the home. Its range includes reverse osmosis systems, undersink filters, countertop water filters, water filter pitchers, faucet filters and replacement filters, with products designed to improve drinking water quality in UK homes. We also note that Waterdrop’s products are NSF-certified, which gives shoppers a clear point of reference when comparing filtration options.
Shoppers tend to look at Waterdrop when they want a fairly focused range across home water care rather than a bit of everything. The brand covers several useful categories too, including Home Appliances, Kitchen & Dining, Health & Wellness, DIY & Tools, and Coffee & Tea. So, if you're sorting out your kitchen setup or just want an easier way to keep on top of filtered water at home, it’s a practical place to browse.

I'm Tamires, a Content Writer at LatestDeals, and I've been helping people save money since 2020. My job is to research, test, and sense-check offers so our community can trust what they see, especially around Waterdrop discount code and Waterdrop voucher savings. My best tip for Waterdrop is to sign up for the newsletter before you buy, because it gives 10% off your first order and is an easy one to use on a bigger basket. Outside work, I'm usually sipping coffee, going for walks, or hunting down a pastry I probably don't need, but fancy anyway.
