We are not sure the exact nature of the attestation you are referring to. Energy cheques are sometimes sent out with an attestation proving the right to certain legal rights associated with being an energy cheque beneficiary, so this could be what this document is.
These rights include not having to pay any fees for starting a new electricity or gas supply service, and certain protections in the case of difficulties with paying gas or electricity bills.

If you are unsure about any specifics as to how to use the cheque, there is a free helpline for questions about the energy cheque (in French) at 0805 204 805.
