We highly recommend NumberGroup …

We've been using NumberGroup’s cloud hosted communication platform since 2016.

Their cloud phone system is reliable and easy to use, plus they have extremely competitive call rates, friendly customer service and faultless support.

One of the key benefits of using NumberGroup has been the significant savings on outgoing call charges - our transition saved our business over £800 a year!

We highly recommend NumberGroup to our business partners and clients – we can't fault the product, service or the attitude of NumberGroup’s employees. We look forward to working with them as our business grows.

I have been a customer of Numbergroup …

I have been a customer of Numbergroup since 2012, Numbergroup supply around 50 telephone numbers, which include international numbers. For us and we also use them on our pbx calls.

Would recommend Numbergroup as they have been very reliable through out the years and have never let me down.

Amazing customer service and very helpful!

Having started my Photography company for the first time, I was a bit worried to take the next step to get any sort of phone system set up. Ben was more then helpful with this and helped me every step of the way! I didn't have a clue on what system to purchase but Ben advised me on what would work best for me. The services are very affordable would recommend!

Great company

Great company, been with them for about 5 years now and their service is excellent, I work for a local authority and have never really had any issues with service, on the odd occasion where our communications equipment has been playing up their technical team has always been there to help.

Fantastic

Fantastic, speedy customer service & super friendly. I'd highly recommend numbergroup for quality & delivery of a cost effective service.
Had our 0800 number for 3 years now and had no problems at all. The call rates are miles cheaper than BT & the savings we've made as a small business are hugely noticeable. Thanks numbergroup.

Best voip in the uk

Ok. We have been with number group for 5/6 years now if not longer and have only ever had one problem over billing and that way because I used the wrong PayPal account. But once in contact I was called back within minutes and everything was back to normal. We are just upgrading to the new luna pbx system and i cant find many voip providers out there that can beat 5000 incoming and outgoing calls to landline and mobile for the price. I know they have bad reviews at the start but i take into account that it was probably a man or a women trying to setup a business and work a full-time job at the same time.

Fast, efficient and prompt service

Superb service and number set up within one hour of enquiry.
Free for six months and highly competitive prices after trial period. I wouldn't go anywhere else.
Possibly the best 0800 number service out there.

Fantastic service.

I feel I must say, Number group offer an amazing service, before I joined them I was with another provider and was messed around so much I needed a change.

I joined Number Group and it was obvious from the start that this was going to be an entirely different experience, the technical side of things is easy, even for a technophobe like me, the customer service is first class, and the value for money equals the service.

All in all, great service, great Company, if you need these services, dont think twice.

A throughly professional experience from the beginning.

In need of a comprehensive telecoms package, I was recommended Number Group. And I could not be happier with the service we have received thus far. They made the transition from our old provider incredibly easy, and have continued to provide high quality service whenever we have queries ever since. They have yet to disappoint in any of our dealings, and I doubt we'll be looking anywhere else for phone services any time soon.

Happy with the service

I chose the free phone number package from Numbergroup for 6 months. The customer service was great and the follow up was very helpful. After 4 months I decided to go with the business package,haven't had any problems so far. They are cheap, provide quality service and the staff are friendly.

DO NOT USE THIS SHABBY OUTFIT

A word to the wise...

This outfit will cut your services without any warning...!

I had 200 numbers in use and because I was late on one payment they switched all numbers off without any warning !

They said my business wasn't worth their effort...

You decide if you want to risk building you business with a company that can and will cut your services because you are a few weeks late with a payment..

You have been warned
