More than six Belgian homes out of ten can be connected to fibre today, against barely 15 % in 2020. That national figure hides a very uneven reality: from one street to the next, you either have access to an ultra-fast connection… or to nothing at all. Here is how to find out in a few minutes whether fibre is available where you live, what it really costs in 2026, and what it brings you compared with cable and fixed 5G.
Proximus remains the driving force. The incumbent operator is building its own FTTH network ("Fiber To The Home", the fibre pulled all the way into your home) and already connects Brussels, Antwerp, Ghent, Liège, Charleroi and Namur, plus more than 200 municipalities. Its fastest plans reach 8.5 Gbps.
DIGI plays the newcomer shaking up prices. It entered the Belgian market at the end of 2024, is laying its own network and, according to the rates published in early 2026, advertises an entry-level fibre subscription at around €10/month. Its coverage is growing fast but remains limited to certain areas: everything therefore depends on your address.
VOO in Wallonia and Brussels, like Telenet in Flanders, rely first on their coaxial cable network, which they keep modernising, while starting their own move to fibre neighbourhood by neighbourhood.
Finally, Orange and Scarlet rent access to the Proximus fibre network (a so-called "wholesale" model): you browse on the same infrastructure, often for a lighter bill. Orange offers symmetrical 1 Gbps at around €45/month according to the rates published in early 2026.
Fibre carries data as light signals through a glass strand. The result: identical download and upload speeds, and a latency (the reaction time of the connection) of just a few milliseconds. Coaxial cable delivers excellent download speeds, but a far slower upload and bandwidth shared with the neighbours. Fixed 5G, for its part, uses a box fitted with a SIM card: no technical work, but performance that depends entirely on the quality of the radio signal at your home.
| Criterion | Fibre | Coaxial cable | Fixed 5G |
|---|---|---|---|
| Download speed | Up to 8.5 Gbps | Up to 1 Gbps | Varies with the signal |
| Upload speed | Symmetrical (equal to download) | Clearly lower | Variable |
| Latency | 5 to 10 ms | Fine, sensitive at peak hours | Depends on radio coverage |
| Installation | Technician required | Often already connected | No work needed |
| Availability | Roll-out under way | Very wide | Areas with 5G coverage |
In short: if you work from home, send large files, play online or share the same connection with several people, fibre makes a real difference. For light use, a good cable or fixed 5G subscription is often enough, and usually cheaper.
Speed.be compares the offers of 11 operators and calculates your real saving over 12 months — free of charge and with no commitment.
Good news: competition has pushed prices down by around 20 % in two years. These are the ranges observed in early 2026:
Add activation fees of €99 to €149 outside promotions — though these are very often waived, as are several months of subscription as a welcome offer. Those temporary discounts make comparison tricky: an attractive rate in the first year can hide a steep bill in the second.
That is THE question, because fibre is deployed street by street, sometimes house number by house number. Two neighbours in the same municipality can have completely different options. You can test your address on each operator's website, but it takes time and has to be repeated every time the network expands.
The simple alternative: let Speed.be check for you. As an independent telecom broker, we query the networks available at your address and compare the offers of 11 operators, free of charge. You get a clear answer: which technologies reach your home, at what speed and at what price — fibre included, or the best alternative solution for as long as it has not yet reached your street.
Count on 10 to 25 working days between the order and the connection, and up to 4 to 6 weeks in rural areas. On the day itself, a technician brings the fibre from the street into your home and installs the ONT, the small box that converts the light signal: allow 2 to 4 hours for the visit.
Before signing, three checks are essential:
Is fibre worth it where you live? If it runs down your street and your household uses a lot of internet, almost always. If it is not there yet, there is no point waiting idly: have your address checked and find out today which connection is genuinely available to you.
