We have set out below the personal data that we collect and how we collect it:

  • Direct interactions: if you give us your name, email address, contact information and other details when you contact us with an enquiry or give us feedback on our services (Identity Data).
  • Banking information: if you provide us with your direct debit details or bank card details (Financial Data).
  • Cookies: we use cookies on our website which collect data such as your IP address, device type, your login information, browser type and version, time zone setting, browser plug-in types and versions, screen resolution, operating system and platform; and information about your visit, including the full Uniform Resource Locators, clickstream to, through and from our site (including date and time), page response times, download errors, length of visits to certain pages, page interaction information (such as scrolling, clicks, and mouse-overs) and methods used to browse away from the page (Technical Data).
  • From industry sources: when you provide us with your address and/ or vehicle registration mark, we pull information from relevant industry databases to understand your energy demand and carbon footprint, in order to provide our services. This data includes your current gas and electricity suppliers, historical gas and electricity usage, switch history, meter type and details, EPC data, vehicle make and model, engine specifications and mileage (Industry Data). We continue to update this data on an ongoing basis until or unless you ask us not to or terminate the service. This may include half-hourly smart meter data if you have given us your explicit consent. Please note that in accessing certain industry data, we may be required to provide the industry data provider with a licence to enable them to provide their service to us.
  • From other companies: We may be contracted by a company that either provides services directly to you or has a relationship with your building (for example, a building management service that provides services to your landlord) (Partner). If you have a direct relationship with them, they may provide us with your Identity Data, plus instruct us to obtain Industry Data on your and their behalf, plus if we power the website interface(s) we will also obtain Technical Data, as above. We will use all of this data in the same way as if we were directly providing services to you and not via a Partner. If you do not have a direct relationship with them, we will not access Identity Data but will access Industry data which may still contain personal data, such as meter point administration number and usage. However, we will never share nor store this data. Access will only be in order to obtain an aggregated view of usage and carbon. Any personal data will be deleted immediately.

Legitimate Interests
We are permitted to process your personal data if it is based on our ‘legitimate interests’ i.e. we have good, sensible, practical reasons for processing your personal data which is in our interests. To do so, we have considered the impact on your interests and rights, and have placed appropriate safeguards to ensure that the intrusion on your privacy is reduced as much as possible.  The table in the section “Why do we process your personal data” explains the personal data processed on this basis.

Sometimes we want to use your personal data in a way that is entirely optional for you, such as Cookies, to ensure our website is optimised for your use.

We also access half-hourly smart meter data based on consent. Your consent will remain valid until you revoke it or at the automatic expiry at 2 years. You will be invited to renew consent at this time. If you fail to do so, we will deem consent withdrawn. This may affect our ability to provide some or all of our services.
