Switching to Z1

Z1 Telecom approached us about switching to them from our existing supplier who's costs were spirraling out of control.
They managed to navigate a way out of our existing long term high cost contract and the switch to Z1 was seamless from start to finish.
With Z1 we now pay a fraction of the costs but receive a far superior support service.
Catherine is very knowlegable,professional and is great to deal with.

Ethan has been extremely helpful

Ethan has been extremely helpful, helping us move away from HiHi to Z1. He did all the legwork and made the transition easy. Mitch came to install the new phone systems and was really friendly and helpful, coming up with easy solutions for us. He set the phones up quickly and made the switch really easy. So far we are really happy with Z1.

Great Company to Deal With

We’ve dealt with Z1 through our other businesses, so when it came to changing over to voip from copper, we turned to them again and Bill and Rich were great, explained everything clearly, gave us a great price and everything fell into place just as they said. Mitch came and did the install and again was so thorough and explained everything and left us feeling happy with everything, just needed plenty of coffee to see him through! Thanks Mitch!

Z1 Telecom Review of service

We recently had our broadband and telephone systems installed with Z1 Telecom, and we’ve been really impressed with the service from start to finish.

The whole team were professional, friendly and knowledgeable, and everything was explained clearly throughout the installation. They made what could have been a complicated process very straightforward and were always happy to answer any questions we had.

A special mention to Ethan, who came out to provide in-house training on the new phone system. He took the time to train two separate groups of staff individually, rather than rushing everyone through it, and made sure that everyone understood how to use the system and was comfortable with the different functions.

It’s that extra level of service and attention to detail that really stood out to us. We’re very happy with both the system and the support we’ve received from Z1 Telecom so far.

Would definitely recommend them to any business looking for a reliable telecoms provider.

Excellent service from start to finish

Excellent service from start to finish. We have been with Z1 telecom for a while and just upgraded our phone system to the cloud version. Lots of new features inc phone app which will be very useful. Thanks to Rich for explaining the new features in a manner which made sense and Bill for taking the time to discuss our renewal options to make sure it worked for our needs. Mitch was great in setting up the equipment, professional as always and checking in to make sure we were happy with everything during the installation.

PROFESSIONAL, FRIENDLY, OVER AND ABOVE.

PROFESSIONAL FROM START TO FINISH
Nothing is too much trouble. Mitch was always asking if we had any questions and showed/explained what we asked.
Andy is just as nice making sure all the systems were operational (coffee white no sugar). They both made sure we were happy with everything and confident before they left.
Mitch mentioned we will then have a visit from Ethan to give us training. This was right. Later that day Ethan followed and explained the portal in more detail. Ethan said if we need any more training he is more than willing to come back and go through what ever we needed.
We never went with Z1 for the costing, we went and stayed with them now over2 /3 years because of how professional they are. To be honest what we get is value for money. NOTHING is too much trouble.
The customer service from the very beginning is second to none.
We recommend then in a heartbeat.

Moved premises no disruption

We have been with Z1 for a while and have just moved premises. They made what was a stressful time so easy with minimal disruption to the business. Came back today to fit new CCTV cameras and again no disruption left clean and tidy and Mitch was great at showing us how everything worked. All of your staff are a credit to you and a pleasure to deal with

Thank you for taking the time to leave such a fantastic review. Moving premises can be incredibly stressful, so we’re delighted to hear that the team helped make the transition smooth and disruption-free for your business.

It’s great to know the CCTV installation went just as seamlessly and that Mitch took the time to ensure everything was clearly explained. We’ll be sure to pass on your kind comments to him and the wider team.

Your feedback means a lot to us, and we truly appreciate your continued trust in Z1. We look forward to supporting your business for many years to come.

Kind regards,

The engineers visited us yesterday to fit our new system.
The process was pain free and we had good communication throughout the installation. Mitch and his team mate could not have been more helpful. The system is very simple and we hope that moving forward it should outshine our previous overly complicated HIHI system that we were miss sold.
