Where We Store Your Personal Data

The personal data that we collect from you may be transferred to, stored and otherwise processed at a destination outside the European Economic Area ("EEA"), including but not limited to Canada and the United States, in which Green Star  Energy, its subsidiaries, agents or third party suppliers maintain facilities, and by using our products or services (including our Site), you consent to any such transfer of information outside of the EEA. Personal data may also be processed by staff operating outside the EEA who work for us or for one of our subsidiaries, agents or suppliers. Such staff may be engaged in, among other things, the processing of your application and the provision of support services. By submitting your personal data, you agree to this transfer, storing or processing and we will take all steps reasonably necessary to ensure that your personal data is kept up to date, treated securely and in accordance with this Privacy Policy.

We will not keep your personal data for longer than is necessary or is permitted by law.

Safeguarding Personal Data

Green Star  Energy is committed to protecting the security of your personal data. We use a variety of technological, physical and organisational protections and procedures to help protect your personal data from unauthorised access, use, or disclosure, such as encryption, passwords and physical security measures. Whilst we strive to protect your personal data, Green Star  Energy cannot ensure or warrant that the personal data or private communications you transmit to us will always remain private.  The transmission of information via the internet is not completely secure. Although we will do our best to protect your personal data, we cannot guarantee the security of your data transmitted to the Site and any transmission is at your own risk. Once we have received your information, we will use strict procedures and security features to try to prevent unauthorised access.

If a password is used to help protect your accounts and personal information, it is your responsibility to keep your password confidential. Do not share this information with anyone.

  • enforce our contract(s);

Green Star  Energy does not, sell, trade or rent your personal data to third parties. We may share your personal data in accordance with the DPA with any member of our group, which means our subsidiaries, our ultimate holding company and its subsidiaries, as defined in section 1159 of the UK Companies Act 2006, or our agents to provide you with product(s) or service(s) you request or to make our business and that of our group more responsive to your needs.

In the event that we sell or buy any business or assets, we may disclose your personal information to the prospective seller or buyer of such business or assets and their professional advisors. Alternatively, if Green Star Energy, its group or substantially all of its assets are acquired by a third party, personal information held by Green Star Energy may be one of the transferred assets.

We may share your personal information with our business partners who may contact you to provide you with details of their products and services.  We may also share your personal data with business partners that help Green Star Energy and/or members of its group analyse and/or improve its communication or relationship with you.  We would share personal data with our Metering partners (to support site visits to read or check the meter), Distribution areas for emergency contacts (e.g supply outages), Debt Collection Agents when customer owe us monies.

We may disclose your personal information in connection with legal enforcement, fraud prevention, or other legal action; as required by law enforcement authorities or other government officials.  This would include instances where if Green Star Energy suspects that you have committed fraud or stolen energy either by tampering with the meter or diverting energy supply, we will record such incident on your account record and share such information with third parties who may have an interest, such as other energy suppliers, landlords, building/housing associations and any regulatory body.  We may use this information to make decisions about you and how likely we think you are to pay for your future energy services. Also if the gas or electricity supply to your property has previously been tampered with or stolen, or we suspect it has been stolen, we may take this into account when we decide what products or services we can offer you and the terms and conditions we give you.

Green Star Energy may ask your previous energy supplier for information that will allow us to take over your supply and you consent to us asking your previous supplier for such information, which may include meter readings and equipment or charges you owe your previous supplier. You agree that we can provide information we hold about you (such as information about meter readings, equipment or money you owe us) to your new supplier so they can begin supplying your gas and electricity.

We may pass your address, property and postcode, and details of your gas appliances, flue, hot-water cylinder, system controls and electrical installations (including details of any repairs or removals) to organisations that supervise these activities. These organisations may pass this information to local authorities to meet building regulations. They may also use this information to contact you to inspect appliances or systems, recall faulty products and carry out audits, and for health and safety purposes.

We may check your details with one or more credit-reference and fraud-prevention agencies to help us reach a decision about your ability to make payments and the products and services we can offer you.

Except as described above, we will not disclose your personal data to third parties for their own marketing purposes unless you have provided prior consent for such disclosure.
