Proximus fibre: are the FTTH deals really worth it in 2026?

Proximus is the provider pushing fibre to the home furthest in Belgium. Where a newcomer like Digi undercuts prices in a few municipalities, Proximus bets on the widest coverage in the country and on complete Internet + TV + mobile bundles. But that ambition has a price: fibre plans start noticeably higher than at the low-cost providers. Speeds up to 8.5 Gbps, free installation, introductory promos that climb after a year: here is our review to know whether a Proximus fibre deal is right for you.

How much does a Proximus fibre plan really cost?

A fibre-only plan starts around €39.99/month and rises to about €78/month for multi-gigabit (recorded July 2026). Between the two, the range covers several speed tiers. If you want an all-in-one bundle, the Flex+ plans (Internet + TV + mobile) run from roughly one hundred euros to over €150/month depending on options. The real price, not the theoretical one: these rates are often shown after an introductory promo. Watch the small print: a reduction of around €20/month for the first twelve months is common, which means the bill climbs in the thirteenth month. Always work out the real cost over two years, promo included, not just the first-year entry rate.

What speed does Proximus fibre reach, and do you need it?

Proximus FTTH deals range from around 100 Mbps at entry level up to 8.5 Gbps download and 8 Gbps upload on the fastest plan. That is among the highest speeds on the Belgian market. But let's be clear: almost no household will ever use such a speed. For 4K streaming on several screens, remote work, video calls and online gaming, a deal around 1 Gbps is already oversized for most homes. Multi-gigabit only makes real sense for very specific uses: regularly sending large files, a home with many simultaneous devices, or enthusiasts who want the maximum. Paying for 8 Gbps when your home Wi-Fi caps out well before is buying a marketing figure. Choose a speed suited to your real usage, not the brochure's superlative.

Is Proximus fibre available at your address?

This is Proximus's real strong point: its coverage. It is the provider rolling out fibre to the home most widely in Belgium, with more than 2.4 million homes and businesses already connectable and a goal of covering 95% of Belgian homes by 2032. The rollout relies on regional partnerships: Fiberklaar in Flanders, Unifiber in Wallonia and GOfiber in the German-speaking region. In practice, this means Proximus is often available where newcomers are not yet. But coverage still varies from one municipality to another, or even one street to another. Before comparing prices, test your eligibility at your exact address: that is what will determine your real options, provider by provider.

How does Proximus fibre installation work?

Technician installation is free, and that's a genuine advantage. Running the cable to your home costs you nothing (the work is valued at around €79), and installation doesn't commit you until you subscribe to a plan. The work usually takes 2 to 4 hours, but the actual connection cut lasts only a few minutes. The technician brings the fibre from the street to a box fitted in the home, then installs the modem. For an apartment, façade installation or work in shared areas may need the building manager's approval — something to anticipate if you live in a co-ownership. Overall, connection is one of the most well-oiled steps at Proximus, thanks to the scale of its rollout.

Who is a Proximus fibre deal really for?

Proximus is aimed first at a specific profile: a household that wants a complete bundle, reliable coverage and an established provider, and accepts paying more than a low-cost option for it. A family that wants TV with a set-top box, a home that wants to combine Internet + mobile + television on a single bill, or a household in a municipality only the big providers cover: the deal makes sense. Who it's for — and who it isn't: if you only need internet, only stream, and price is your first criterion, a cheaper provider like Digi may be enough, provided it covers your address.

Proximus versus the competition: what to remember?

Against Telenet, Orange, VOO or Digi, Proximus stands out for the widest FTTH coverage and for complete bundles, not for price. Where Digi bets on a floor rate with no TV, and cable providers rely on existing networks, Proximus is building a new fibre network across much of the country. That's reassuring in terms of longevity — fibre to the home is the most powerful and stable technology available today. The downside: you pay for that lead, and introductory promotions can mask the real cost. The right approach stays the same: check eligibility first, then compare the total cost over two years between the deals actually available where you live.

Conclusion

Proximus is not the cheapest fibre deal in Belgium, and doesn't try to be. Its strength is unmatched FTTH coverage, well-oiled free installation and Internet + TV + mobile bundles for households that want everything combined. Its limits: a high entry rate and promotions that climb after twelve months. Before subscribing, test your eligibility, choose a speed suited to your real usage rather than the highest figure, and compare the cost over two years against the other deals in your area.
