The circumstances in which we share and transfer the data we hold about individuals

Scheme Participants have the opportunity to share their contact details with other Scheme
Participants via the GGCS Registration Database. It will always be your choice whether you consent to us sharing your data, with whom and for what purpose. You will be obliged to opt-in in writing or online in order to give any consent. We may disclose your data if we are required to do so by law, or in order to enforce our own legal rights.
All Scheme Participants will have signed a letter agreement which includes clauses relating to confidentially. If you are a Scheme Participants (a Gas Producer or a Gas Supplier) or an Associate Member and are unsure of what is included in those clauses please send an email to
We will not under any circumstances transfer your data outside the European Economic Area (EEA). Given that, holding data about individuals on the internet, which is a global environment, means that it may be processed outside the EEA. If this were to be the case, the data will always be held securely and in line with the requirements of UK data protection legislation. 

The basis on which we hold and protect data about individuals

Where we process personal data from individuals who are employees or representatives of Scheme Participants the lawful basis for that processing is contractual. This processing is necessary for us to administer the Scheme in an efficient manner, ensuring that participants are able to access the Registration Database and are kept informed about Scheme developments. 
We may process some personal data on the basis that individual has consented to receive communication from the Scheme. Such persons may withdraw their consent at any time.
We will delete any data we hold about individuals after 10 years unless you request in writing within that time to continue to hold your data.
The GGCS website, the Registration Database and the GGCS CRM database are all protected and have a high level of security. We are committed to ensuring that your data is secure. In order to prevent unauthorised access or disclosure, we have put in place suitable physical, electronic and managerial procedures to safeguard and secure the information we hold.

How individuals will know if we decide to change this Privacy Policy

Should we decide to change this Privacy Policy statement in any way we will put a notice on our website to inform you of the changes and what their significance could be for you. We will also make this information available in any emails we send out to individuals who could be affected.
This Privacy Policy statement was adopted on February 21st 2024. There is a version control number at the start of the document so that you can easily trace any amendments which have been made to it and when.
