A letter from your energy supplier lands: your termijnbedrag is going up, or there’s a tariefswijziging. Dutch energy bills are full of words that sound alarming and cost money if you misread them. Here is how the bill actually works, what a tariff change means, and when you can simply walk away.
The termijnbedrag is a prepayment
First, the figure that worries people most. As ACM ConsuWijzer explains the termijnbedrag, your termijnbedrag is a monthly advance payment, an estimate based on your expected yearly use and the price.
It’s not your real cost. Once a year, in the jaarafrekening (annual statement), the supplier compares it to what you actually used, and you either pay extra (bijbetalen) or get money back (teruggave). So a high termijnbedrag isn’t a charge, it’s a prepayment that gets reconciled.
Tariefswijziging: when they raise the rate
The other alarming word. As ACM ConsuWijzer explains rate increases, on a variable contract the supplier can change tariffs (e.g. when wholesale prices rise), but must announce a tariefswijziging generally about 30 days in advance.
A change to your termijnbedrag has a lighter notice rule, but still needs a good reason. On a fixed (vast) contract, your rate is locked for the term.
Your escape hatch
Here’s the power you have. As the price-increase guidance notes, with a variable contract you can always cancel without a penalty (notice period per your contract). So if a tariefswijziging makes your deal uncompetitive, switch.
A fixed contract is different and may carry an opzegvergoeding (early-exit fee). Think an increase is unjustified? Write to the supplier, and you can report it to the ACM.

Where it connects
Your energy bill ties into the wider home-utilities picture, submitting your meterstanden (which keeps the termijnbedrag accurate), choosing a dynamic contract, and the household systems behind it, the CV-ketel boiler. Switching for a better rate is the same yearly habit as the December zorgverzekering switch. It’s also one of the official-looking bills you must actually read, like a blue-envelope letter from the Belastingdienst, and it’s part of setting up a home from scratch, alongside getting your internet connected.
The bottom line
A Dutch energy bill runs on a termijnbedrag (monthly prepayment) settled in the yearly jaarafrekening (you bijbetalen or get a teruggave). A tariefswijziging on a variable contract can raise your rate, but with ~30 days’ notice, and you can cancel a variable contract penalty-free and switch. Learn termijnbedrag, jaarafrekening and tariefswijziging, submit accurate meter readings, and an intimidating bill becomes something you can challenge or escape.

Frequently asked questions
What is the termijnbedrag on my energy bill?
The termijnbedrag is your monthly advance payment for energy, an estimate based on your expected yearly use and the price. It’s not your actual cost; once a year the supplier compares it to what you really used in the jaarafrekening (annual statement), and you either pay extra or get a refund. So a high termijnbedrag isn’t a charge as such, it’s a prepayment that gets reconciled annually.
Can my energy supplier just raise my rates (tariefswijziging)?
On a variable-rate contract, yes, the supplier can change tariffs, for example when wholesale prices rise, but they must announce a tariff change (tariefswijziging) to you, generally about 30 days in advance. A change to your monthly termijnbedrag has a lighter notice rule but must have a good reason. On a fixed contract your rate is locked for the term.
Can I cancel my energy contract if the price goes up?
If you have a variable contract, you can always cancel it without paying a termination fee, the notice period is in your contract or terms. So if a tariefswijziging makes your variable deal uncompetitive, you can switch suppliers. A fixed contract is different and may carry an opzegvergoeding (early-termination fee). If you think a rate increase is unjustified, write to the supplier and you can also report it to the ACM.
