The Registry of Certificates on TESSA does not act as a trading platform. Trading of certificates occurs outside TESSA. You are responsible for arranging the sale of any certificates that you generate as an Accredited Certificate Provider.

TESSA provides the platform for registering the ownership of a certificate. Whenever a sale or trade occurs, the transfer of ownership must be registered on TESSA in accordance with the requirements of the Electricity Supply Act 1995 and the Electricity Supply (General) Regulation 2014.

For information about transferring the ownership of certificates, see the Transferring certificates page.
