Reasons we collect your Personal Data and the grounds for which we process it

Personal Data which we do collect:

Information        Reasons why it is necessary to process
Online identifiers such as IP address and device identifiers To study website and app usage and efficiencies in order to improve our products and services to you, including the operation of our websites and apps.
Personal details such as your name, date of birth, address, etc. To enter into a contractual relationship with you, for example a contract of supply of energy.
Contact details such as your phone number and email address In order to contact you about important information regarding your application or contract with us.
Financial details such as your bank account number and cardholder name To arrange Direct Debit payments or take card payments from you for supplied energy.
Vulnerability information such as health/medical conditions To place you on our Priority Service Register if you feel you or someone in your household is in a vulnerable situation.
Documentation to support a change of name request, such as a marriage certificate, decree absolute or deed poll

Bills from your previous supplier, legal  documentation, tenancy agreements or copies of cheques or bank statements To allow us to resolve enquiries and complaints, where it is necessary for us to request this information.
Details of your household income  To ensure that we’re offering you the best tariff for your circumstances, we may request this data to check whether you are eligible for certain government discount schemes or tariffs.
Sanctions screening To facilitate compliance with legal and regulatory obligations, we carry out screening on our customers, business partners, and on individuals associated with our existing and potential business counter-parties. This screening takes place against publicly-available or government-issued sanctions lists and media sources. This screening includes individuals such as customers, directors, officers, sole traders, shareholders and key stakeholders of our current and potential counter-parties. The purpose of this screening is to enable us to protect our assets and employees/contractors, and specifically to ensure that we can comply with trade control, anti-money laundering and/or bribery and corruption laws and other regulatory requirements. This screening does not result in any automated decision making.
Credit checks

We will perform automated processing in the form of a credit check before we open an account for you. We use credit referencing agencies to confirm the following:

  • that you live at the property you’d like Green Star Energy to supply;
  • the previous addresses you may have occupied;
  • your credit score. This is calculated by credit reference agencies based on information including (but not limited to) your financial accounts, credit applications and insolvency related events.

If you fail to pass our credit checks we may ask you for a security deposit or provide you with a prepayment meter before we set up your account.

For more information regarding how your personal data is processed by credit reference agencies and how your credit score is calculated, please visit Experian’s Credit Reference Agency Information Notice at


If you have consented to receive communications from Green Star Energy, or if you have previously purchased similar goods/and or services from us, you may receive offers that are tailored towards your preferences based on the information gathered about you from the various sources described above in order to provide you with better products and increasingly tailored services.

We may send you service updates and notifications without your advance consent only where such updates and/or notifications are necessary for the proper functioning of the services that you use.

You may receive pertinent offers and communications by different channels and you may update your subscription preferences via contacting our customer services team or using the unsubscribe functionality for the different digital channels.


We will process your Personal Data for the purposes set out above because:

  • you consented;
  • you have gained consent to supply another’s Personal Data, such as emergency contacts;
  • it is necessary for complying with a legal obligation;
  • it is pursuant to our legitimate interests, such as the pursuit for the payment of debt or the establishing, exercising and defending of our legal rights;
  • it is pursuant to a substantial public interest.

Any processing of your Personal Data by us will be done in a manner that is proportionate to the task pursued and with security measures to safeguard your rights and freedoms in relation to that information.

Where the processing is based on consent, you have the right to withdraw your consent at any time. This will not affect the validity of the processing prior to the withdrawal of consent. However, choosing to withdraw your consent may affect your ability to fully interact with us or participate in our programs or services.  

Special category data and public task. Where we process your health data, or any other special category data about you, we may rely on the substantial public interest involved as an additional condition for processing that data.

We may use your data or share it with other organisations in situations where we know you require additional assistance and either we, another supplier, or industry organisations (i.e. distribution network operators and gas transporters) need to process your data so you can continue to receive appropriate services to meet your needs and to ensure you remain on supply.


Sharing your Personal Data

Your personal information may be shared with any company that is a member of our Group of companies, which includes, Shell Energy Retail Limited (SERL), and our parent company Royal Dutch Shell plc, where necessary for internal administrative purposes, corporate strategy, auditing and monitoring, sanctions screening, and research and development. (For more information on how your personal information will be used for sanctions screening, please see the “Reasons we collect your personal data and the grounds for which we process it” section of this Privacy Policy.) 

In addition, we may disclose to:

  • anti-fraud services;

  • external professional advisors to our group of companies subject to obligations of confidentiality;
  • debt collection agencies;
  • data aggregation services;
  • third party service suppliers such as billing services and customer service administration;

  • any legal authority for the purposes of detection, prevention or investigation of crimes or threats to public safety;
  • potential third party acquirers in the event that we sell or transfer a portion or all of our business or assets.


Transfers of Personal Data

From time to time, we may need to transfer your personal data to authorised third parties located outside of the European Economic Area (or the UK in the event the UK is no longer part of the European Economic Area). When we do send data outside of the EEA, we take organisational, contractual and legal measures to ensure that your personal data is exclusively processed for the purposes above and that adequate levels of protection have been implemented to safeguard your personal data. These measures include:

  • Binding Corporate Rules, the European Commission approved transfer mechanisms for transfers to third parties in countries which have not been deemed to provide an adequate level of data protection as well as any additional local legal requirements;
  • Sending information to countries which have been deemed as having adequate protection by the EU;
  • Entering into European Commission approved standard contractual arrangements with the third party.
For more information, please contact us at [email protected].


Data security

We implement technical and organisational measures specifically drawn to protect your Personal Data against unauthorised, accidental or unlawful access, loss, alteration and disclosure. These measures all aim to handling your information to achieve data minimisation. This means that we process selected pieces of your Personal Data given within your consent only as required for the task at hand. If the task does not require your Personal Data, that portion of your information will not get processed. If the task does require your Personal Data, we would pseudonymise it so that it is sent in files that separate that from the remainder of the information.

Data retention

If your contractual relationship with us ends without any outstanding issues for resolution and without any outstanding legal obligations on our part to retain your Personal Data, we will remove it from our records within a reasonable amount of time after the end of that relationship.

If it ends with potential outstanding issues, we will retain your Personal Information:

  • for 6 years when that issue is reasonably identifiable;
  • for the duration of resolution of that issue until it is resolved entirely, whichever is sooner. We would retain the minimum amount of your Personal Data as necessary in order to identify the relevant pieces of information relevant to resolve the issue.

Whenever the removal of your Personal Data is due to be removed from our records, we will do so within a reasonable amount of time after that. We have processes which ensure the deletion of information after it is appropriate to do so and systematically, your information when it is due to be removed should be removed at the next cycle of systematic deletion.

Your rights

You have certain statutory rights in relation to the Personal Data that we hold about you as your Data Controller, including:

  • the right to receive copies of the Personal Data we do hold;
  • confirmation of the nature of processing, whether we disclose it to third parties and where those third parties are located;
  • the right to request rectification of any inaccuracies in your Personal Data;
  • the right to request erasure of Personal Data which we have on record for you which is not strictly necessary to our performance of our contractual and legal obligations;
  • the right to withdraw your consent of our processing of your Personal Data to the extent that your withdrawn consent does not obstruct our performance of our contractual and legal obligations nor impairs our rights as Data Controller to maintain amounts of information regarding you in order to exercise our rights to legitimately use that data, for example in the pursuit of debt you owe us;
  • the right to lodge a complaint with an official data protection regulator should you feel that we have processed your Personal Data in contravention of your statutory rights and freedoms.
