What to know about ION8

Written by the company

Leak-proof across the whole range
Every ION8 bottle, mug and flask is leak-proof. It can go in a bag next to a laptop, a change of clothes or a packed lunch and stay where you put it. It's the thing we design for first.
Lids, seals and straws sold separately
A worn seal shouldn't mean a new bottle. We sell replacement lids, seals, straws and filters for the current range, so a bottle can be kept going rather than replaced.
Hot or cold for hours
Insulated ION8 bottles use triple-wall vacuum insulation with an internal copper coating. Drinks stay hot or cold for hours, and the outside stays dry — no condensation on a desk or in a bag.
Bottles for school and lunch bags
ION8 kids' bottles are built for the bag they actually live in. Leak-proof, dishwasher safe, and a wide opening so they can be cleaned properly. Matching lunch bags and slings are available too.
One bottle body, three lids
Primo is our modular range. Every lid fits every Primo bottle in every size, so a straw lid for the commute and a screw top for the weekend work on the same bottle. Lids are sold separately from £12.99.
Personalised and engraved
Bottles, travel mugs and flasks can be personalised with a name. These are made to order, so they can't be returned unless faulty.
Free UK delivery over £40
UK orders over £40 ship free on Royal Mail Tracked 48, with Tracked 24 available as an upgrade. Europe is free over £60, and the rest of the world over £70.
Designed in the UK
ION8 is a British drinkware brand based in Dundee. The Primo range won a Red Dot Design Award in 2026, and ION8 holds a German Design Award from 2024 and a King's Award from 2025.
Certified carbon neutral
ION8 is certified carbon neutral across all operations. Products are designed to be reused rather than replaced, which is why spare parts are stocked for the current range.
Buying from the US
US customers should order from ion8.com, which carries the core collection and ships domestically. The UK site ships internationally, but shipping costs apply.

I ordered ION8 bottles and the payment…

I ordered ION8 bottles and the payment was successfully deducted from my card. Five days later, I was informed that my order had been manually cancelled and that I should simply place the order again.

The bigger issue is that no refund was actually processed, and I was given no information about when I could expect my money back.

When I contacted customer service, Stewart Cowie sent me a screenshot claiming that the order had been refunded and that the order had been cancelled after payment due to a stock allocation/fulfilment issue, despite the payment having already been successfully taken, and that, if I couldn't see the money, I should contact my card provider.

However, the screenshot he provided clearly shows that the order was manually cancelled and that the refund is still pending — not processed. The cancellation email I received from ION8 also indicates that the refund is pending.

It is extremely frustrating to be told that a refund has been issued when the company's own documentation shows otherwise. If a refund is still pending, customers should be given a clear explanation and an expected processing timeframe rather than being directed to their bank.

I expected much better customer service and transparency from ION8. I would strongly recommend improving the refund process and, most importantly, providing accurate information to customers about the status of their money.

Great bottle for people who forget to lock their bottles

I love ion8 bottles since discovering them and recently changed all my travel bottles to ion8 as I am super clumsy and always spill my drinks everywhere but ion8 has solved that!

Recently I had also dropped my biggest thermo bottle after having for less than a month and was devastated. But got in contact with ion8 and they have sent a replacement straight away! So thank you so much Ellvee from the support team for being so kind!!

Easy to order and a lovely free gift

Easy to order and a lovely free gift. Unfortunately the delivery company was very delayed with no updates. I got in contact with ION8 and Inah came back so quickly and offered help. Fortunately by this point the bottles had been delivered. Amazing bottles and great quality alongside fantastic customer service.

Problem with free gift

The quality of the bottles are fantastic and they keep cold for a couple of days. They do not leak and are superior to other bottles. I had an issue with ordering the free promotional gift and at first the company would not resolve my complaint but then they had a change of mind and sorted it out for me. Had it been resolved at first point of contact I would have given 5 stars.

Had a technical issue

Had a technical issue with the lid of my ION8 1ltr container. Sent in pictures and had a very prompt response from a lady called Inah. She was superb, she asked for a video of the issue, acknowledged everything at each stage in a friendly and professional manner. Everything sorted quickly and a new lid on its way via post. All sorted quickly and with empathy. Thank you INAH for your service in this matter.

Superb company I love the way they are…

Superb company I love the way they are trying so hard not to wasteful to the environment. Most companies you would have a broken part of a bottle and that’s it straight in landfill. These guys are great even out of warranty they have helped me giving my son a new lid for free even tho I would have paid them.

I brought a 1 litre insulated bottle on amazon. The bottle keeps my water cool all day.

I had a problem as the insulation inside cracked after a few weeks.

After speaking with Inah in customer services. Who was very friendly and helpful I now have a new product in the post.

I will update on the new bottle, great service just hope the product was a one off.

These bottles are leakproof 100%

These bottles are leakproof 100%
I was sceptical at first but my grandson has used one for a year in primary school. Apart from a few dents on the bottom it has served us well. We have just ordered a new one for the next school year , only because my grandson would like a different design

Great product & support team

Purchased a metal insulated water bottle, a plastic one and a coffee cup.

The water bottles from these guys are honestly the greatest. My kid takes the insulated one to school and even in the heatwaves it kept water freezing cold all day and even if she refilled it at school with water from the tap it actually chilled it abit due to the fact the bottles inside were still so cold even when empty. Been chucked at concrete many times, is kept in her bag upside down and doesn’t leak a drop. She loves the choice of designs. We will only buy these bottles in future!
I love my plastic water bottle as it’s the same easy to drink from design and is such a pretty colour, doesn’t drip anywhere.

I had a slight issue with my coffee cup but customer service have been amazing, the beauty of their cups is all seals and parts like the top you can get separately so they quickly resolved the issue for me. Big thank you to Inah at support who was so quick in replying and sorting it for me.
Great company.

Make the commitment and buy a water bottle from these guys, it’ll save you a fortune in the long run and to be fair I actually find their pricing very reasonable in comparison to similar companies and they certainly live up to their claims!
