Spain: Fenadismer asks CNMC to publish the list of fuel stations that did not apply the diesel discount

We previously reported that the actual professional diesel discount in Spain came to just 5 cents, far below the 20 cents promised under Royal Decree-Law 18/2026. Fenadismer now takes it a step further: from asking for compensation to asking for sanctions.

What changed

At a meeting with Economy Minister Carlos Cuerpo, the federation presented concrete figures: in September, the discount owed was 12 cents per litre, but in the first few days it only reached 6 cents — and meanwhile the pump price rose by a further 16 cents, effectively wiping out the tax benefit for anyone refuelling.

What Fenadismer is asking for

Based on the publication and monitoring obligations set out in the June Royal Decree that created the second transport aid package, Fenadismer is asking the Ministry to instruct Spain’s National Markets and Competition Commission (CNMC) to publish, without further delay, the list of fuel stations with anomalous pricing behaviour and the monitoring report already required by law. The list would give hauliers grounds for complaints and give the Tax Agency a basis for inspecting the stations named.

Why it matters for hauliers leaving Portugal

Anyone crossing Spain to refuel at lower prices should keep their receipts: if the CNMC does publish the list, it could become the basis for reclaiming the discount not applied on refuelling already done since September.
