How much you can save through the group buying auction partly depends on the prices offered by the winning supplier and, of course, your personal energy consumption. Mega and EnergyVision won the May 2026 auction with the best deals for variable and fixed contracts. Mega's variable contract and EnergyVision's fixed contract were both 31% cheaper than what was currently being offered on the market.*

If you’re wondering how much you could save, just open KBC Mobile and sign up. 

* The prices currently offered on the market are derived from the average of similar contracts currently offered by the six largest suppliers in Flanders, namely ENGIE, Eneco, Mega, Elegant, TotalEnergies and Luminus. A similar contract is one with similar or the same conditions as the contract for the group buying scheme.

Our partner ‘Switch Together’ specialises in group buying schemes and brings consumers together to strengthen their position in negotiations with energy suppliers. By combining the purchasing power of a large group of people, participants gain access to cheaper prices for gas and electricity.

Switch Together is a time-limited offer. You can sign up through the KBC Mobile app free of charge and with no obligation. Even if you’re not a customer with us, enter the details stated on your annual energy statement or final bill.

If you’ve already signed up, you’ll receive your personal proposal after the energy supplier auction and find out how much you can save on gas and electricity.

Once you receive your personalised proposal, you have one month to accept it.

If you’re happy with the proposal, accept the contract and our partner will ensure that switching to your new energy contract goes hitch-free. You don’t have to do a thing. It’s all done for you!
