What is a fixed-price energy contract?

If you choose a Electricity or Gas Contract at a fixed price, this means that the price you pay per kilowatt-hour (kWh) will always remain the same throughout the entire contract. This ensures a stable price over a defined period (often one year or three years). This is the security option.

What is a variable price energy contract?

Contrariumwith a energy contract at variable rate the price of the kilowatt-hour you pay will be indexed every month or every three months based on a specific index.

For example, for gas, the majority of suppliers use the TTF103 index (quarterly reference index for gas in Belgium). So, the gas price per kilowatt-hour (without fixed components such as network cuts) is computed according to the TTF103 + X formula, or
– TTF103 is the value of the index that varies each quarter (expressed in c€/kWh);
– X represents the supplier’s margin (expressed in c€/kWh).

This type of contract tends to to be closer to the most premature of the market. Selecting this option This could result in reduced rates when electricity or gas prices are significantly lowered on wholesale markets, but you may also have the impact of a price increase.

Advantages and inconsistencies of fixed and variable prices

You will have understood both of them own advantages and unconveyors.

Fixed price:

  • Benefits : Prices are stable, so you don’t risk unpleasant surprises when receiving your down payment bill. You stay safe from unexpected pricing on the energy market.
  • Inconveyors: In exchange for this security, the supplier is taking on a slightly larger margin on a fixed price contract.

Variable price:

  • Benefits : You can get integrated discounts if the market price decreases during your contract. In addition, tariffs for this type of contract on the subscription date are usually lower than those for fixed-price contracts.
  • Inconveyors : The risks are higher, and you will not have protection in the event of price increases.

Please note that variable prices as fixed prices only affect the energy portion in the total price you have to pay. This represents about one fifth of your invoice. Its exact share varies according to your area and the type of energy. To see what other components make up your invoice, you can visit the CREG site.

Can we really compare fixed and variable prices?

In the meantime, it is rather complicated to compare fixed prices and variable prices because of their nature. Indeed, for an effective comparison, you should take into account the price change that occurs monthly or quarterly for the variable rate. However, it is impossible to predict it accurately. One solution would be to use the prices of the last 12 months to try to find a trend. However, this exercise will not allow you to obtain a prediction or complete comparison between the two types of tariffs.
