Fibre Optic in Belgium 2026: Operators, Prices and Installation

Fibre optic now covers more than 60% of Belgian households, compared to just 15% in 2020. If you are still hesitating to make the switch, this guide explains everything you need to know about fibre in Belgium in 2026: available operators, real prices, installation timelines and pitfalls to avoid. Speed.be, an independent telecom broker since 2000, compares more than 200 offers to find the best fibre deal for your address.

Why switch to fibre optic in 2026?

Unlike VDSL or coaxial cable, fibre optic transmits data via light, offering three decisive advantages:

  • Symmetrical speed up to 10 Gbps for both download and upload (ideal for remote work, cloud and 4K streaming)
  • Ultra-low latency (5-10 ms) — essential for gamers and video conferencing
  • Total stability: no speed drop during peak hours, unlike shared cable

In 2026, Proximus, VOO, Orange and Telenet have massively invested in FTTH deployment. The result: fibre prices have dropped by 20%.

Which operators offer fibre in Belgium?

Proximus Fibre

Proximus is the historical leader with its own FTTH network, covering Brussels, Antwerp, Ghent, Charleroi and more, with speeds up to 8.5 Gbps.

VOO Fibre (Wallonia and Brussels)

VOO is progressively rolling out FTTH fibre in Wallonia, complementing its DOCSIS 3.1 cable network.

Orange Fibre

Orange uses the Proximus wholesale network and frequently offers more competitive pricing for equivalent performance.

Telenet Fibre

Telenet mainly covers Flanders with an ongoing mix of HFC and FTTH progressive deployment.

How much does fibre optic cost in Belgium in 2026?

  • Fibre internet only (1 Gbps): 45 to 65 EUR/month
  • Internet + TV bundle: 65 to 90 EUR/month
  • Internet + TV + Mobile bundle: 85 to 130 EUR/month

Fibre installation: timeline, cost and process

Average lead time

In 2026, the average fibre installation lead time in Belgium is 10 to 25 working days after ordering. Rural areas may experience slightly longer delays.

Installation costs

Most operators offer free installation with a 12 or 24-month commitment. Outside promotions, expect 99 to 150 EUR for a technician visit.

Work at your home

A technician runs a fibre cable from the street to your home and installs an ONT (Optical Network Terminal). No drilling through load-bearing walls is required.

3 pitfalls to avoid before subscribing

  • The "up to" speed: an advertised speed of "up to 1 Gbps" can drop to 300 Mbps in practice. Always ask for the guaranteed speed.
  • Hidden commitment: some promotions require a 24-month commitment with cancellation fees of up to 200 EUR.
  • Rented router: renting a modem at 7 EUR/month for 2 years adds 168 EUR in extra costs. Prefer purchasing or a compatible model.
