Why choose a fixed-rate energy plan?
Certainty about your energy rates
No price increases
With a fixed-term contract, your rates are fixed, so you won’t be surprised by sudden price increases.
The supply rates for electricity and gas remain the same throughout the entire contract period, regardless of fluctuations in the energy market.
You can choose a contract term of 1 or 3 years and enjoy complete certainty during that period.
€876 cheaper than variable rates
Suppliers offer competitive rates and generous sign-up bonuses only to new customers.
However, most Dutch people have a variable-rate energy contract. Suppliers make more money from these contracts because they don’t have to pay out a bonus and can raise rates during the term of the contract.
Our research shows that a fixed-rate contract is therefore, on average, €876 cheaper per year.
Generous sign-up bonuses
Suppliers are eager to attract new customers and therefore offer generous discounts, especially on 1-year contracts.
On comparison sites like this one, those discounts are often even higher than on their own websites, which means they appear at the top of our comparison tool with the best deals.

What is a fixed-rate energy contract?
A fixed-rate energy contract is an agreement in which the rates for electricity and gas are fixed for an agreed-upon period (usually 1 or 3 years). During this term, your rates will not change, even if market prices rise.
In addition to providing certainty, our research (2025) shows that a fixed-rate contract is also always cheaper than a variable-rate contract.
Advantages of a fixed-rate energy contract:
- Fixed rates, so certainty
- Generous sign-up bonuses
- Benefit from a switching discount every year
- No need to worry about your energy bills
Disadvantages of a fixed-term contract:
- You don’t immediately benefit from price drops
- Risk of a penalty if you cancel early
A 1-year or 3-year fixed-rate plan?
According to Melvin Paalvast, an energy expert at Keuze.nl, a 1-year contract is usually the most cost-effective: rates are lower, and 1-year contracts typically come with relatively higher sign-up bonuses.
Are you looking for long-term security? Then a 3-year fixed-rate energy contract is a great option. You won’t have to worry about anything for 3 years.
Is a fixed-term energy contract a good idea?
Yes, a fixed-rate energy contract is a wise choice. A fixed-rate contract gives you price certainty and offers significant savings compared to a variable-rate contract. A 1-year contract is particularly advantageous: you benefit from a new welcome bonus every year.
Solar Panels and Fixed-Rate Contracts
Do you have solar panels? Even then, it’s advantageous to choose a fixed-rate energy contract. This allows you to fully benefit from the net metering program and get the most out of your solar panels.
Frequently Asked Questions
What happens when my fixed-term contract ends?
Once your fixed-term contract expires, you will automatically be transferred to an open-ended contract. You can then cancel your service at any time.
Tip: Switch suppliers as soon as your contract expires. That way, you’ll get another welcome bonus and avoid higher rates.
Did you know that Keuze.nl automatically notifies you when you’re eligible to switch again?
Want to cancel your fixed-term energy contract early?
If you cancel your fixed-term energy contract before the agreed-upon date, the supplier may charge a cancellation fee. This fee depends on:
- The remaining amount of electricity/gas based on your estimated annual consumption
- The reference rate; the resale value of the energy purchased for you to a new customer
- The rates at which you originally applied for the contract
The early termination fee varies by situation and will be calculated on a per-contract basis. The supplier determines the amount of this fee based on the loss they incur.
What rates are "fixed" under a fixed-term contract?
- Supply rates: the price per kWh of electricity and per m³ of gas.
- Fixed charges: the fixed costs per month, quarter, or year
Please note: suppliers are free to set these rates themselves, under the supervision of the ACM.
Which costs are still subject to change?
- Energy tax: this is a government levy
- Grid operator cost: costs for transmission and maintenance
These costs are set at the national level and may change each year.
