Square UK Reviews 

impossible to contact them, office seems to be not in the whole day even though called 9-5 on a tuesday. there is a bug on their website/app which doesn’t allow you to link your bank account. even when you buy the physical square reader. impossible to use and impossible to get help

I have found the SQUARE card reader (very inexpensive) and interface/software really, really easy to manage and versatile. It has been so easy to set up Payment/Donation links to be used for websites. We are not a business per se, but an individual trader & non-profit. I would really recommend.

regarding a card payment taken through my Square Reader on 11 August 2026.

I have been using Square to take payments for my business and, on this occasion, the payment appeared to have been successfully processed. The Square Reader displayed the smiling face confirmation, which I understood to mean that the payment had been successfully taken.

However, when I checked my Square app afterwards because I had not received the funds, I noticed a message saying that I had unfortunately run out of time. When I investigated further, there was no payment activity showing in my account.

I contacted Square Support and spoke to an employee who was very understanding and helpful. After checking my account history, I was told that the payment had actually gone through and that there had not been a loss of connection. However, I was told that because I had not confirmed the payment within the required time, the money would not be paid to me.

This is extremely concerning because I had no understanding that I needed to carry out an additional confirmation after the smiling face appeared on the reader. In my experience, the smiling face had indicated that the payment had been successfully completed, and I had no reason to believe that I still needed to take further action.

I was advised to contact the customer and ask them to pay me again. I have done this, and the customer initially confirmed that the payment had not gone through. I have since asked them to arrange payment, but they have now stopped responding to my messages.

As a small business, losing money for a service I have already provided is extremely difficult. I followed the payment process as I understood it and relied on the confirmation displayed by Square.i have now lost all trust in the square company and will be taking my business somewhere else one that support its customers during situations like myself

I was moving from sum up to square.
Unfortunately most of the time using my iPhone it says “card type denied” or “use another card”.
I then try customers card on sum up card reader and it goes straight through.

Easy to setup and could take payments via my phone. I would get a card reader but they don’t have a display, so customers can’t check amount before tapping.

After years of using different card reader companies, I finally found my favorite: fast payment, no need to turn the device on and off, and most importantly, you can easily see what you earn on the main page. A respectful company. Thanks, guys!

I have only just set up with square and am still learning but I have had to uninstall and reinstall the app by the second use as it would no longer work and the app told me uninstall it. I also have not been able to make my square reader work yet or the tap to pay on the phone and have had to put card details in manually which is annoying, but I will continue to try and work out why certain aspects are not working. It only took a day or 2 for the funds to appear in my bank account and otherwise has been a breeze to set up and use.

Excellent service, good rates, highly recommended.
We needed a card reader for our charity that would provide an easy way for people to donate and for us to access reports. The whole experience was excellent, from start, setup to taking donations. And now, reports are available without painstaking communications with a provider. All round - excellent!

I can take payments on events, this was brilliant, once it was all set up, it was very easy to take my first payment, tho we got a card reader, we didnt really need it, as it took the payments from my phone. But nice to have for a back up.

The only reason it is not 5 stars is for some small reasons. The TLDR is that is works and I think it's a really good option for small businesses who are not selling in person consistently enough to justify paying for a dedicated card reader, but it does have some options that look good for people who are larger/ more consistent in person sellers. Make sure you give yourself enough time between needing to use it and setting up your account, they need time to confirm your bank!

Small negatives: I had anxiety over making sure it definitely worked with my phone, and it felt a little frustrating that there is not some way for a small test payment, so I am not sending 3 quid to myself through square, and losing a small percentage of that £3 to squares fees for the privilege of making sure it works. Now it is a tiny percentage (2.5%), but I think a way for a small no fee test payment to confirm it works would be a good idea, if possible.
Other small thing was in the app itself, it wanted me to set up items and customer profiles, which just wasn't needed for my purposes at the time, and no matter how many times I got rid of the notification, it would always come back up and seemed to have some weird moments perhaps because I wasn't doing them?

Positives: It is easy to set up and free. I chose it because it lets me use my phone to take payments rather than having to purchase a card reader, and had seen other small creators using it at art markets. This was my first time selling in person and it worked really well, was quick to use and has the amount clearly on the screen so you can show customers how much you have typed in. I was also then able to go through the app to record how much and when each payment was.

It's nice that they give you a free trial of their premium features as well, that does not automatically continue. When the trial ends it just stops, and you can yourself choose if you want to go in and continue it.

I also appreciate it is upfront about the money from each sale that square takes for processing. They tell you percentages, but also tell you from each sale what is taken, and how much has been taken overall, and it is reassuring to see the numbers clearly laid out.

Money is moved into your account within 2 days for free (or you can pay an small additional fee to move it instantly if you need it faster), and that all happened smoothly!

I am not a business and I only need a card reader for a weekend every 2 years! so this is perfect, it's easy to set up, easy to connect to bank and the app made payments so easy. It's now tucked away again until 2028! thank you!

The lady helping me spent quite some time helping me to solve the problem I was experiencing with the square reader. She was patient and finally I managed to get it all sorted.

I purchased the reader from a large wholesaler. Was worried about there not being g any instructions in the box at first, but once the item is charged up, every step is done on the reader itself. Overall happy with set up.

I was surprised as got a personal email back and refunded me the money back as I bought new square reader didn’t expect that.

Simplicity, instant transfer if you want.. not one single issue with payments..my card reader let me down daily.. losing signal..but square is through my phone..

Really easy to sign up and use both the app and card reader hardware.
Quick response on some pending issues.

The square card reader is a great price and easy to set up work lots of features my previous reader didn't offer. The only downside is that if you make a mistake inputting an amount you cannot cancel or amend and have to refund customer and start again.

Great customer service via phone. Unfortunately my square reader keeps unpairing.

I had a couple of problems using my new card reader for the first time. I reached out to them and received a very polite, respectful and helpful response first time. Definitely recommend.

Seamless, links quickly with bank and Xero, ideal form of payment, makes my life easier not having to carry around a card reader
