All about the installation

Are you ready for fiber?

The Proximus network is being modernized: traditional copper cables are gradually being replaced by fiber cables. But what do you need to switch to this new technology?

A city where fiber is coming

Fiber is available in several major cities in Belgium and is being rolled out or planned to be in others. So the first thing to do is to check if your city is concerned.

An address where fiber is available

As fiber cables are laid neighbourhood by neighbourhood and street by street, check whether fiber is already available for your business. If such is the case, order the Fiber pack of your choice now!

A business connected to fiber

In order to enjoy the full benefits of fiber, it must be installed right into the heart of your business. One of our technicians will come to install your connection box to fiber and activate your Fiber pack 

Any more questions?

First, check if fiber is available for your address.

  • If this is the case, you will be invited to order your fiber products online and make an appointment with one of our technicians to install the fiber connection box and activate your products on the agreed date. Please note that a power socket is required near this box. Follow the instructions on our website.
  • If fiber is not yet available for your business but Proximus is planning to install it in your street, fill in the online contact form that appears on your screen. One of our employees will then contact you as soon as possible to give you more information about the probable installation period and answer any questions you may have.
  • Finally, given that we are rolling out fiber in several phases, your business may be located in an area where works have not yet been planned or in an area in which we are unable to install fiber for technical or administrative reasons. In this case, however, you will only be contacted when fiber is available for your address. But in the meantime, you can of course continue to enjoy your current Proximus products until fiber is available for your business.

We lay our fiber cable in your neighborhood, street by street. To allow fiber to be installed up to your business, preparatory work is needed, i.e. excavation or facade work. We'll do everything we can to minimize disruption and will always keep you informed of the schedule.

Once the work has been completed in your street, you’ll be able to choose the Fiber Pack that best suits your needs. You’ll then be contacted so that a technician can come by, on the agreed date, to install the fiber connection box free of charge - so that the fiber arrives discreetly into your company's premises - and to activate your products. Please note that a power socket is required near this box

Yes, connection to the network and the installation of fiber are free of charge for eligible addresses within 3 months following the first notification of the arrival of fiber, with any activation of a Fiber Pack. In industrial zones, connection is also included for up to a maximum installation fee of €1.550 excl. VAT per customer. An estimate will be drawn up for any amount over €1,550 and you will be free to accept it or not.
