The price of a certificate varies depending upon the type of certificate.

The price of RECS certificates and Guarantees of Origin is set by the market, and influenced by such factors as when the energy was produced, the source of the energy and the type of production device. It is also influenced by the size of the transaction, large trades attracting lower prices than small trades.

Currently, EECS does not support those certificates put in place by governments specifically to support national support schemes: the price of these being set (or influenced) by government.
