Where your information will be held

When we share your information, your information may be transferred outside the European Economic Area.

We store our information on cloud servers located in the USA, or engage vendors which do not always have equivalent data protection laws to those applicable in Europe. The transfer of this information is therefore governed by a contract including standard contractual clauses (SCCs) approved by the European Commission. Our client on-boarding team is based in India which does not have equivalent data protection laws to those applicable in Europe. The transfer of information to them is according to company rules that set out how we treat and protect information.

When you provide us with this information you are consenting that we may collect and use it in the way we've set out.

We will keep your information for as long as it is reasonably necessary. It will depend on factors such as whether you've still got an active account or any outstanding debt with us or have interacted with recent offers. We will retain and use your registration information as necessary to comply with our legal obligations, resolve disputes, and enforce our agreements.

We will only transfer data to jurisdictions outside the scope of the European General Data Protection Regulation (GDPR) where the appropriate safeguards set out in the GDPR are in place.


Your rights

You may have certain rights in relation to your information including a right to access or to correct the information we hold on you. Some of these rights will only apply in certain circumstances, however, such as the right to be forgotten or the right to request that we move your information to another company. They will generally not be available if there are outstanding contracts between us, if we required by law to keep the information or if the information is relevant to a legal dispute. If you would like to exercise or discuss any of these rights, please contact the Data Protection Officer.

  • You can remove consent, where you have provided it, at any time, as well as update any of your opt-in marketing preferences by phoning us on 0333 200 5100, logging into your account on MyAccount, or following this link;

Security and accuracy

We are committed to keeping your personal information safe. We've got physical, technical and administrative measures in place to prevent unauthorised access or use of your information. We also require that our suppliers protect such information from unauthorised access use and disclosure. 

We will also routinely refresh our information to ensure we keep it up-to-date.

__utmbThis cookie is used to establish and continue a user session with your site. When a user views a page on your site, the Google Analytics code attempts to update this cookie.

New Relic cookies

New Relic uses an enhanced version of the Episodes  JavaScript library to perform browser measurements, the same library used by Google Analytics. Page load timing (sometimes referred to as real user monitoring or RUM) also creates the following cookies in end-user browsers.

This cookie is only created in browsers that do not support the Navigation Timing API. When a browser supports the Navigation Timing API, a native interface can be used to determine navigation start time.NREUM is a session cookie that is deleted when the browser closes.


This cookie is created only when a token is handed out to an end user by the New Relic server. End user metrics are communicated to New Relic servers via a JSONP request from the browser (script retrieval). The returned JavaScript contains a call to set the token identifier which is written to the cookie on the next navigation (when the page unloads). This achieves a cross-domain communication between New Relic servers and the New Relic agent. This cookie is used to communicate between the New Relic server aggregating end user metrics and the agent(s) running in the associated web application. A token identifies and correlates application tier transaction traces with corresponding browser traces.NRAGENT is a session cookie that is deleted when the browser closes.

How we protect your personal information

EDF Energy takes the protection of our customer’s information very seriously.

For security reasons, as with all organisations, it wouldn’t be appropriate for us to disclose specific details as to how we protect information. We’ve taken a ‘defence in depth’ approach to Information Security, especially regarding our online services.

Our systems are kept up-to-date and we test our online services to make sure they’re secure and that unauthorised access is prevented.
