Belgium has approved an unusual settlement between competing broadband networks that will reduce duplicate fibre construction across suburban Flanders while attempting to preserve retail competition through regulated wholesale access.

Proximus, its fibre subsidiary Fiberklaar, Telenet, and network company Wyre will divide responsibility for building infrastructure in covered areas. Instead of two operators digging parallel routes and connecting the same streets, one network will generally be built and made available to the other group.

The Belgian Competition Authority approved the arrangement after the companies offered commitments governing cooperation and access. More than two million homes and businesses are expected to become connectable, with most construction planned by June 2029 and the remainder extending towards 2037.

Dense urban markets, where parallel fibre networks may remain commercially viable, sit outside the main agreement. In some sparsely populated areas, Telenet and Wyre will upgrade existing hybrid fibre coaxial infrastructure rather than replacing every connection with fibre to the premises.

Construction economics have overtaken coverage targets

Fibre deployment requires substantial upfront capital, while revenue arrives gradually as customers switch from existing broadband services. Building two networks along the same suburban street can preserve infrastructure competition, although it also duplicates roadworks, permits, ducts, equipment, and disruption before either operator knows how many households will subscribe.

Those economics have become harder as European operators move from announcing premises passed to converting available connections into paying accounts. Extensive fibre coverage does not repay construction costs unless customers migrate, while price competition can stretch the recovery period further.

The Flanders agreement uses shared construction to improve the investment case without creating a single retail provider. Whichever company builds in a covered area must provide access to the other participating group, while additional service providers will also be able to obtain wholesale connections.

Operational terms will determine whether that access supports meaningful competition. Wholesale prices, repair times, installation processes, product flexibility, and access to network information can all influence whether another provider can compete effectively. A contractual right to use a network offers little protection when service standards favour the company that owns it.

The Belgian Institute for Postal Services and Telecommunications will monitor the commitments, while the competition authority has imposed rules covering the division of areas and third party access. Municipalities will also need updated information as planned roadworks and permit applications are revised around the new structure.

Europe is reconsidering physical duplication

The agreement reflects a wider argument over how much infrastructure competition remains economically sustainable outside dense cities. European policy has encouraged fibre investment because high capacity fixed networks support cloud services, industrial systems, remote work, public services, and mobile backhaul, yet the cost of reaching less concentrated communities can exceed the returns available to several builders.

The EU’s Gigabit Infrastructure Act is intended to reduce construction costs by improving access to ducts, poles, buildings, and public assets, while simplifying permits. Cooperation between operators can deliver similar savings, although it creates a stronger need for regulatory supervision once parallel networks disappear.

Belgium’s model is neither a conventional merger nor a fully separated national network. Ownership remains divided, retail brands continue to compete, and construction responsibility changes according to location. That structure may retain more commercial pressure than a single national wholesale operator, but it will also be harder to supervise consistently.

Municipalities should see fewer repeated roadworks, while operators gain a clearer route to covering areas that might otherwise be delayed. Customers may receive faster connections sooner, although the longer term outcome will depend on whether shared infrastructure supports genuine product and price choice.

Network quality will offer another test. When two retail providers rely on the same physical connection, service differentiation shifts towards customer support, routers, business products, security, installation, and reliability. The infrastructure owner must also have enough incentive to maintain and upgrade a network used by its competitors.

The approval establishes a framework rather than proving the model. Construction milestones, take-up, prices, access disputes, and service performance will show whether Flanders has found a workable balance between the efficiency of one build and the competitive pressure that gives operators a reason to improve it.
