To facilitate the necessary administrative steps, your new supplier deals with the termination of your present supply contract as part of the procedure for changing supplier.
By signing a contract with a new supplier, you also give that new supplier the mandate to terminate your existing contract with your old supplier; you do not have to take any further steps and there is no risk of a break between the end of the existing contract with your old supplier and the start of supply by the new supplier. Your new supplier will supply you with energy no later than 3 weeks after the date of your change request.
Nevertheless, you should be aware that you must respect the notice period set out in the special conditions or even the general conditions of the supply contract you wish to terminate, otherwise penalties will apply.
In the case of a distance or off-premises contract with a supplier or as a result of cold calling, the consumer has the possibility of withdrawing from the contract within 14 days of its conclusion.
