Very disappointing experience

Very disappointing experience. I purchased a tap from this company, but it was never sent. After a lot of back and forth, I was told that a replacement would be sent, but despite numerous emails chasing this up, they eventually stopped responding altogether.

I have given them plenty of opportunities to resolve the issue, but unfortunately I’ve been left without the product or a proper response.

I would strongly recommend thinking twice before ordering from this company. Extremely poor customer service and a very frustrating experience.

Terrible

Do not use this company . I bought a combination hot water tap on sale at £900. When delivered it had a missing part so could not use it.
I have messaged by email and chat for 4 months being completely ignored.
Now going legal for a refund and bought elsewhere.

I find myself having to review again as it’s the only way to get an answer.

They have commented under mine saying resolved when it isn’t.

I got asked if I accepted an upgrade FOC would I delete my review, I said sure once I have it fitted for a few months I will remove my review if it is all okay. Well my review is still up ….

The ‘upgrade’ doesn’t stop dripping and constantly running when off, filling up a measuring jug at least once a day. Have emailed the same person and provided videos / pictures but have heard nothing yet again. This is now my second tap in 16 months from them, not looking good. Works perfectly when it wants to for a few months but seems to have issues once it’s been installed for a few months.

Yet again not happy and having to leave a review as they don’t reply to emails.

25th October Update
Still no reply to emails or anything even though I have a 3 year warranty. Tap is now turned off as constantly leaking when boiling and won’t stop beeping at us as if we are pressing a button. Shocking service yet again.

My previous review is still below for context.

Arno tap still unresolved

Since registering the complaint the customer service is worse than ad hoc. The electrical unit replaced eventually (the review clearly got them into action) but the issues around the tap are still ongoing. I get ad hoc emails - have sent all the evidence they ask for - yet still unresolved. The tap spits out hot water, pressure is variable, drips when off…

I have had the Arnotap 4 in 1 for several months. It has preformed really well and I have had no issues so far. Set up was easy and so is changing the filter. It looks great and I am very happy with the purchase.

Nice tap but customer service leaves a lot to be desired

The tap arrived well packaged and exactly as it looked. Assembly was easy enough although there were no instructions so had to watch videos online as to how to assemble, but it was straight forward. The valve I was sent leaked upon fitting and when I contacted customer services they said they were out of stock but sent me a link to Amazon where I could purchase my own! I responded and made them aware of their legal obligations under warranty and they then sent me out a replacement bought from Amazon. The item sent from Amazon seems of better quality and this has meant there is no leak. Their build quality seems to be good enough but time will tell. Also their filters are very expensive at £59 for a 6 month filter so beware of this when purchasing.

After posting this review they contacted me and sent out the item themselves as I highlighted I was concerned that if I purchased it then it wouldn't be covered by any of their warranty.
They also confirmed they'd give me a 9 month supply of filters (1 every 3 months for the 9 months) as a good will gesture which is a nice gesture, I just wish they'd thought through how, sending a new customer a link to a replacement part, would look to the end customer

Selling taps which are not safe

Selling taps which are not safe, filtered and boiling water is provided through the tap via one pipe. This is a complete safety issue.

Customer service is the worst; I have to chase to get replies. Avoid at all costs.

Hi Ismail,

Thank you for your feedback, and we're sorry to hear about your experience reaching our customer service.

We'd like to gently reassure you on the safety point, as it's important to us and to anyone reading this. Our taps are designed and tested to meet UK safety standards. Multifunction taps that deliver boiling and filtered water through a single spout use separate internal channels, so the different water types do not mix, and the system is built specifically for safe everyday use.

That said, we completely understand your frustration with having to chase for replies, and that is not the standard we aim for.

Our team has been in touch regarding your order to make things right, and we'd encourage you to check your inbox and reply so we can fully resolve this for you.

Warm regards,
The ARNO Team

Zero customer support – avoid at all costs

Title: Zero customer support – avoid at all costs

I purchased a 5-in-1 tap from this company and, to be fair, the product itself is fine. Unfortunately, that’s where the positives end.

When it came time to replace the filters (which are essential to the product), I found they were listed as “sold out” on the website. Since then, I have made multiple attempts to contact the company through every available channel – their chatbot (no response), email (no replies), and even attempts to reach their parent company, Kastalia Taps – again, no response.

For reference, these are the contact details publicly listed on the Kastalia website:

Mobile: 0044 7777 454223

In my experience, I have not received any response via these methods, and the phone number has not connected.

I also checked Companies House and noted missing filings, which raises concerns about the current status of the business.

The key issue is this: this product requires ongoing replacement filters, yet there is no way to obtain them or get any form of customer support.

I would strongly advise anyone considering purchasing from this company to think carefully. Without support or access to essential parts, the product becomes effectively unusable.

Avoid.

I’ll add that today, they are now showing product in stock and I’ve purchased via shop to have an audit trail. Let’s see if it gets delivered. Still nothing from a customer care point of view so my above stands. Shocking service really.

Awful product and customer service

DO NOT BUY ANYTHING FROM THIS COMPANY! Their customer service is absolutely awful. Good luck getting a reply or any help if you have any problems as you can't actually speak to anyone! The boiling element of our tap is now not working, it's been nearly 2 weeks and numerous emails and videos sent and still no reply!

We had an issue with the filter fitting weeks after buying and it took weeks for someone to take action and help out. And when they did they then promised me they'd send me extra filters by way of apology and then didn't bother sending them. I would avoid buying anything from them ever again.

Hi M. Cunliffe,

Thank you for your feedback, and we're genuinely sorry to hear about your experience with both the product and our communication.

We acknowledge that our response times in your case fell short of the standard we aim to provide, and we understand how frustrating it must have been to feel unheard, especially when you had already been waiting on a promised resolution.

Our team did reach out to you directly to try to resolve matters, and we're sorry we weren't able to find a solution that worked for you.
We continue to work on improving both our products and our after-sales support, and we take all feedback seriously as part of that process.

Warm regards,
The ARNO Team

I accept there can be faults but it’s how they are dealt with that matters

If I could give zero I would. Tap was delivering water at 82deg from the spout, not 98 as it was set to. The digital display started to lose digits, then intermittent operation and finally it’s packed up. This was since installation in dec, 4 months. Through out this I’d contacted Arno numerous times ( 6) with video evidence. Every time they promised the earth but did zero. Now going to ombudsman as they have a duty under the consumer act. I now have a non functioning useless tap.

Since writing the review Arno have been in contact and fully resolved the problem. In fact they couldn’t have been more helpful. There was a delay in response but this was somewhat outside their control and partially my fault with responses going to my junk folder.
Despite the initial frustrations (which are now understood) the Arno response has been first class.

There is no way to communicate with them. No phone number, don't respond to emails and don't respond to the web chat. I have questions about an order I have received and cannot get an answer. Avoid!

Missing part from the order

Missing part from the order and after contacting their service email (no phone number for services) I’ve not heard back so it feels like Arno is uncontactable and we feel very let down. / UPDATE - I did today hear back from ARNO Customer service team and they resolved matters and kindly have agreed with me via email a suitable outcome. I am grateful to Arno for getting back to me and can now say that they do follow up and will sort problems once notified.

Constantly Drips

It has dripped since I bought it the dripping speeds up when it is boiling as you can hear the mechanism - I like the tap - but probably losing a lot of water and paying the price

After sales is a joke

Tap was good for 7 months, now the safety feature has broke. Happy days I have a 3 year warranty …. Apart from I would if they actually help, I’ve been contacting them every day for 2 weeks, getting told they will contact me once resolved, I had to send a 2 minute video of the taps pluming even though that was fine, it’s the safety feature that’s broke. I have to keep chasing them every day and I’m getting nowhere. I ordered replacement filters aswell, had to chase them up as had nothing for over a week with ‘express delivery’.

Taps good, service is shocking

Although we have finally resolved the issue for you, I am sorry you’ve had to chase us for updates and that the filter delivery was delayed.

Great Instant Hot Water, but Confusing Feature Limitations for the Price

Overall, this is a solid faucet with excellent water pressure. Having readily available filtered water at 98°C is incredibly useful for cooking and hot drinks. However, the product falls short in terms of features and value structure.

Technically, it would be much better if the temperature sensor worked for regular hot and cold water, rather than just the filtered line, and I missed having a spray mode.

I was also surprised by the pricing logic. The 4-in-1 model costs £509, while the 3-in-1 is £369. The 3-in-1 filters the water for the boiler, so it seems like a missed opportunity not to provide that same filtered water as a cold option without the boiler engaged. It feels steep to pay an extra £140 just to access ambient filtered water when the filtration hardware is effectively already there.

Great experience

From the minute I ordered the tap to now using the tap it’s been a great experience.
The website was easy to use and at first I thought something wrong because the price was so competitive. I did the install myself and couldn’t really be simpler
Great installation instruction and and the kit well boxed up
The tap itself is so easy to use and feels really safe
The look with its digital display is an amazing addition to our kitchen
