Fixed, variable or dynamic: Dutch energy contracts explained
Dutch suppliers offer three contract types. Which is best depends on how much certainty you want and whether you can shift your usage.
A fixed contract locks your rate for a set period, giving certainty but usually a small premium. A variable contract can change (typically twice a year) and follows the market. A dynamic contract changes every hour with the wholesale price, which can be cheapest if you can move usage to cheap hours and you have a smart meter. There is no single best type; it depends on your risk appetite and flexibility.
Fixed contracts (vast)
A fixed contract sets your price per kWh and per m3 for a fixed period, often one to three years. You know exactly where you stand, which is reassuring when prices are volatile. The trade-off is that you usually pay a small premium for that certainty, and leaving early can carry a capped fee.
Fixed suits people who want a predictable bill and do not want to think about energy again for a while.
Variable contracts (variabel)
A variable contract follows the market and can change, in practice usually at fixed moments (often twice a year). You are not locked in, so you can leave with short notice, but your rate can rise if the market rises. Many people who never actively chose end up on a variable standard rate, which is often not the cheapest option available.
Variable suits people who want flexibility and are willing to keep an eye on the market.
Dynamic contracts (dynamisch)
A dynamic contract changes every hour, following the wholesale electricity price. If you can run the dishwasher, charge the car or heat with a heat pump during cheap hours, it can be the cheapest option. It also carries more risk: during peak hours the price can spike. You need a smart meter for a dynamic contract.
Dynamic suits engaged users with flexible usage, solar panels, a home battery or an electric car, who are comfortable with prices that move.
How to choose
Ask yourself two questions: how much do I value a predictable bill, and how flexible is my usage? If you value certainty, lean fixed. If you want freedom without much effort, variable. If you can actively shift usage and want the lowest possible price, dynamic. Whatever you pick, the comparison ranks real contracts of each type on total yearly cost.
Frequently asked questions
Which energy contract is cheapest in the Netherlands?
There is no single cheapest type for everyone. Dynamic can be cheapest if you shift usage to cheap hours and have a smart meter; fixed gives certainty at a small premium; variable sits in between. The cheapest contract for you depends on your usage pattern and how much price risk you accept.
Do I need a smart meter for a dynamic contract?
Yes. Dynamic pricing changes every hour, so the supplier needs hourly meter data, which requires a smart meter. Most Dutch homes already have one; you can request one from your network operator if not.
Can I switch contract type later?
Yes. When your current contract ends (or now, if you are on a variable contract you can leave with short notice) you can move to a different type. Many people try dynamic once they have solar panels or an electric car.
What is the difference between a smart meter and a dynamic contract?
A smart meter is the digital meter that sends readings automatically; almost everyone has one. A dynamic contract is a pricing model that uses those hourly readings. Having a smart meter does not put you on dynamic pricing; that is a separate choice.
