The last communication from BIPT – IBPT is an important moment for customer protection and tariff transparency in Belgium. Link to Press Release

With its decision of 28 January 2026, the Regulator clarifies how Articles 108, 109 and 110 of the Electronic Communications Act must actually be applied. In doing so, it brings more order and structure to provisions that existed in the Law but were not always implemented in a consistent way.

Belgium now stands out in Europe. It is currently the only EU country requiring operators to proactively inform customers every year about their most advantageous tariff plan. Other Member States have transparency obligations, but not with this level of recurring, structured requirement.

👉 So what does this mean in practice?
Any operator offering more than one standardised tariff plan must:
↪️ Inform each customer at least once per year about the best tariff plan
↪️ Base this tariff recommendation analysis using 3 months of usage data
↪️ Apply the same logic at contract renewal
↪️ Be able to explain and justify the calculation methodology if audited
↪️ Be fully compliant within 9 months

👉 This concerns large and small operators alike
👉 And it also applies to B2B customers served through standardised offers

Two things really matter here :
1️⃣ Methodology. It’s not enough to say a tariff is “better”. Operators must define how they calculate that, apply it consistently and be able to document it.
2️⃣ Timing. Nine months may sound comfortable, but when data flows, internal processes and possibly IT systems are involved, the clock moves fast.

The legal framework is now clearer. Expectations are more structured. The countdown has started.
