Great but needs a few extras

This is a great service and hats off to the operators. IMO it needs a built in spellcheck/autocorrect function and better multitasking support to include the ability to paste pre written text during a call. Personally I find it hard to type information in a structured manner under pressure making it hard for me to correctly provide details for the operator to express what I’m on about correctly to the caller which extends an already long call with awkward silences whilst I slowly type one fingered then read what I’m sending in case of typos.

Addressing barriers

I have just started using the app as someone with tinnitus and autism, who finds telephone calls really difficult (I don’t make them unless it’s an absolute crisis). This app is enabling me to make timely calls eg to get my vehicle fixed so I can leave the house again, to call NHS when a phone appointment didn’t happen etc. I am now making my way through a list of calls I’ve needed to make for so long and getting the healthcare etc I need at the re than just not having it and making the important calls, that for many others are just a part of daily life.

Absolutely Life-Changing – A Must-Have App!

Relay UK has completely transformed the way I communicate. As someone with hearing difficulties, I used to feel very isolated when it came to making phone calls – but this app has opened up a whole new world for me. It’s simple to use, reliable, and incredibly empowering.

The interface is clean and intuitive, and the connection to the relay assistant is always fast and professional. The text comes through clearly, and I love that I can type my responses directly in the app. It works seamlessly whether I’m calling my GP, booking appointments, or just chatting with friends and family.

I’m especially impressed with how well it integrates with my regular mobile number – I don’t have to use a separate device or explain anything to the person I’m calling. The experience is smooth, discreet, and dignified.

I also really appreciate that it works for emergency services too – knowing I can call 999 via Relay UK gives me so much peace of mind.

Many thanks for your detailed review. We're delighted that Relay UK is working for you exactly in the way it's intended to!

It’s good but…

I really don’t want to sound rude, the app is awesome and does help, but a lot of the time I get put through with an agent with a really strong accent and when it comes to things like the DWP virtual assistant or anything virtual the bot has a really hard time understanding and it’s a constant back and forth, and then i’m put through to an agent for something that could’ve easily been updated through the virtual agent. I’ve also noticed that when I get put through to speak to an actual person, it seems like the relay people just hang up the call??? As if they don’t want to be stuck on the waiting line?? Obviously that’s not very helpful.

Thanks for your feedback. The Relay Assistant won't disconnect a call until you're ready to end the conversation, but sometimes the person you're calling can hang up or get disconnected. If you have any specific examples where you don't think this is the case, please let the Helpdesk know and they will investigate - relay.uk.helpdesk@bt.com

Absolutely amazing.

I am not fully deaf, but I have hearing loss and tinnitus. Phone calls can be extremely difficult for me, and on a bad day, can actually be painful. I downloaded the Relay App about a year ago but was too worried about using it. I wasn't sure how it would work, and I was really nervous. I finally plucked up the courage to give it a go. I've chosen to type my side of the conversation and have the other persons side typed too. This means that for me, any call I make is just like using a live chat facility and it has been a life changer for me. I've always had to have someone else with me when I was dealing with a company who only let you call them, and had no email/chat facility, but being able to make calls to anyone by myself has been such a massive help to me.
I feel less of a burden to my friends and family, and have regained a little bit of my independence.
Whoever came up with this idea deserves every single medal and accolade, and the agents who deal with these calls are godsends.
Thank you to all involved in this incredible service.
