Validate your certificate

Enter your details in the box below

If you are a gas consumer who has purchased green gas you will have been given an electronic or hard copy of a Green Gas Certificate. This certificate is proof of the authenticity and uniqueness of the gas that was injected and tells you where, when and how the gas was produced.

To check that it is genuine, enter in the box below one of the Renewable Gas Guarantees of Origin and the pin number, both shown on the certificate.

The system will check that the two match and will display the gas consumers name to which Renewable Gas Guarantees of Origin have been retired to.

Renewable Gas Guarantees of Origin can only be assigned to one consumer. This is your proof that the gas has only been sold once, and that it has been sold to you.

We just need the following information:
