These statements will have been generated by the SAV registry hosted at www.greengas.org.uk and are referred to as Retirement Statements.
They are created when RGGOs are retired and are an electronic statement which lists the RGGOs that have been retired and allocated to an end-use consumer. These Retirement Statements can be verified by entering the RGGO details and the pin number here.
An example retirement statement can be downloaded here.
These statements will have been generated by the G-REX Registry, operated by Grexel, and are referred to as Cancellation Statements. Cancellation and Retirement are two terms for the same process.
Cancellation Statements generated by the G-REX contain a URL (if this option is selected by the Account Holder during cancellation) which can be shared and used by any party to check the validity of the statement.
Contact the GGCS to be provided with an example statement.
