However, prices may change due to changing market conditions or government decisions. The price calculation is based on october 2026 tariffs.

An energy rate card summarises the most important information about an energy contract, such as the type of contract (fixed, variable or dynamic), the price per kWh, the fixed fee, any indexation formulas, duration and termination conditions. You will also find information on discounts, green electricity, injection tariffs for solar panels, network tariffs and an estimate of the annual cost. Here you will find an overview of all current and past rate cards of Luminus MaxxFlex.
Below you will find answers to the most frequently asked questions about Luminus MaxxFlex. Is your question not listed? Feel free to contact us.
Yes, Luminus MaxxFlex is a indexed tariff, i.e. the consumption price per kWh fluctuates every few month(s). The kWh price can therefore rise and fall during the term of your contract. However, the consumption price always follows the same market indexes using a fixed price formula. You can find all the price information and indexation formula in the tariff sheets.
When you switch suppliers, your new supplier Luminus takes care of everything. They will contact both your local grid operator and your previous energy supplier. Your switch usually follows 30 days after your request, but you can also choose a switch date yourself up to 6 months in the future. If you have requested a new connection or move, Luminus also takes care of everything, and then everything can be set up even faster.
Consumers are always entitled to a free cancellation period of 2 weeks after application. For this, you need to contact your new supplier yourself, or contact your current supplier and ask them to stop the switch. Business users are not entitled to 2 weeks' notice.
No, consumers in Belgium are still allowed to switch suppliers for free, and without giving any reason. You are not bound to a fixed contract duration. However, sometimes early termination means you lose your welcome discounts. We therefore advise you to remain a customer for at least one year before requesting an energy switch.
When the original contract term of 1 or 2 years is about to expire, Luminus will notify you. In this, they will offer you a new contract proposal with the same or similar tariff plan. This is the moment you should definitely come and compare your energy contract again on DareToCompare.be.
Luminus MaxxFlex is only available in Flanders & Wallonia, not in the other regions.
