Can my energy supplier raise my monthly advance?

DIRECT ANSWER

Yes — but only if your actual consumption (or tariffs) rose significantly, and only with proper substantiation. Unreasonable hikes you can refuse.

Reviewed by FFCheck-redactie · Last reviewed 2026-05-28

Your monthly advance is an estimate based on expected annual consumption × tariff. The supplier may adjust when

  1. measured consumption has demonstrably risen,
  2. tariffs changed significantly, or
  3. the annual statement showed a large balance. NOT allowedarbitrary increases to manage the supplier's cashflow. Requirements: written notice, transparent calculation, reasonable lead time (minimum 30 days). Think it's unreasonable? Request the calculation in writing, keep paying the old advance, and on refusal send a formal notice. On conflict: Geschillencommissie Energie.
