With our fibre reaching all the way into your customers’ premises, they can enjoy unparalleled speeds and reliability that others can only wish for.

Unleash the Power of Full Fibre Broadband for Blazing Fast Internet Speeds.

To upgrade to extremely fast Fibre broadband, it’s important to check if this technology covers your area. Check your address coverage!

Ultra-fast, symmetrical speeds and extremely low latency.

A Full Fibre connection straight to your business allows for symmetrical and gigabit-capable upload and download speeds, ultimately leading to improved efficiency and productivity. Our network is not limited by copper, as seen in other ‘fibre’ broadband services, so the capacity is practically unlimited.

In addition to the high speeds and limitless capacity, Full Fibre connections also provide more reliable connectivity. As there are no copper wires to degrade or interfere with the signal, the connection is less prone to interruptions and dropouts. This means that businesses can rely on their internet connection to stay connected and productive throughout the day.

Prioritised Business Support

Our Fibre broadband network is committed to a target fix time of 8 hours for any outages, and we offer additional mobile assurance to address issues within 4 hours. If we are unable to resolve the problem within the 4-hour timeframe, we will offer you a temporary broadband failure backup solution to ensure that you stay connected online.

Our company offers a guarantee that if we fail to repair your service within 24 business hours, you will receive a credit on your next month’s bill. This credit will be equivalent to one week for each day that your service was not working after the initial 24-hour period. However, please note that this guarantee is limited to one credit per issue or a series of associated issues.
