Your registration:

Upon receipt of your complete registration, IBBK Fachgruppe Biogas GmbH will invoice you by e-mail. The registration for an IBBK event is legally binding. Each participant has to fill in his own registration form. You will receive the invoice by e-mail, which is considered as a reservation. Upon receipt of your payment, your reservation is confirmed. Admission will only be granted if the registration fee has already been paid.

Please note the following: We issue our invoices in accordance with applicable German law. With regard to value added tax (VAT). this means that invoices for participation in:

Attendance events (conferences / trainings) that take place in Germany will always be issued by us with VAT. According to the German Value Added Tax Act (§ 3a UStG), the “Reverse Charge” regulation cannot be applied, even for companies that are based in the EU and have a valid VAT identification number.

Online events will be invoiced by us:

  • to private persons always with VAT,
  • for companies that have their registered office in Germany always with VAT,
  • for companies that have their registered office in the EU and provide us with a valid VAT identification number, using the “Reverse Charge” regulation without VAT, and
  • for companies from non-European countries without VAT only if a company certificate is sent to us together with the registration. This must be legible for the German tax authorities – i.e. in German or English.

Exhibitors at and sponsors of face-to-face events are subject to separate VAT regulations, which will be pointed out at the appropriate places.

If the number of places is limited, the order of registration will decide.


Cancellation must be made in writing. Until 15 days prior to the start of the event, the participant will be charged an administrative fee of 10% of the invoiced amount (minimum 150€). In case of later cancellation or no-show (also due to illness) the full participation fee is due. If the participant is unable to attend, a substitute participant can be named. The name of this substitute must be communicated to the organizer in writing up to 4 working days before the event.

Cancellation of the event:

In case of cancellation of the event by the organizer, the full participation fee will be refunded. Further claims are excluded.
