Dutch energy market 2026: Tibber leads rankings, Mega sinks to bottom

Based on more than 10,400 consumer reviews, the 2026 Dutch energy‑supplier rating places Tibber at the top with a score of 9.6, praised for its transparent pricing, real‑time hour‑price app and lack of long‑term contracts. UnitedConsumers follows with an 8.9 rating, noted for clear monthly statements and responsive customer service, while Zonneplan scores 8.7, offering dynamic tariffs and extra compensation for solar feed‑in.

The list also highlights major incumbents: Essent (8.5), Vattenfall (8.1), Budget Thuis (8.1), Greenchoice (8.0) and Eneco (7.9). At the opposite end, Mega receives the lowest score of 3.4, with complaints about deceptive sales calls, unexpected bill increases and erroneous final statements. Other low‑rated providers include Frank Energie, Coolblue Energie, Innova Energie and ANWB Energie.

The rankings reflect consumer priorities such as service quality, transparent billing and how providers handle issues, rather than purely price differences, and they are compiled from reviews on platforms like Trustpilot and Energievergelijk.nl.
