What are cookies?

Cookies are small text files that are saved to your computer. We use cookies to remember users during a visit, upon return to the site, and are required to enable certain functionality. In addition, cookies are used to help us understand how our customers use our websites and we use this information to help plan improvements to the site enabling us to get to know you better. For example, using persistent cookies allows us to recognise you when you return to the site, identify your preferences so as to provide you with a more personalised service and speed up searches that you conduct when visiting. Below are details of how we currently use cookies, with details of how you can manage their use.

How to control the use of cookies

If you wish to restrict or block the use of cookies on your computer when you visit our website, you can do this through the cookie preference centre or your browser settings. The "Help" function within your browser should also give details of how to delete cookies already on your computer.

How we use cookies

Both npower and third parties make use of cookies when you visit websites. The following is a description of the types of cookie that we use, why they are used and details of the individual cookies.

We use both session cookies and persistent cookies.

Session cookies are used by us to recognise a user throughout a visit. This enables us to remember information that you have entered such as the product you have selected during a purchase which can then be used at each stage of processing your purchase. Session cookies are also used to remember you when you log in for the duration of your visit.

Persistent cookies allow us to retain information and settings about a user for more than one session. These cookies stay on a computer or a device until they expire or a user removes them. They enable us to recognise a user when they return to our site, identify their preferences so as to provide a user with a more personalised service and speed up searches a user conducts when visiting the site. They allow us to tailor marketing and servicing messages to users based on what we know users have or haven’t done in previous sessions. We are able to optimise the website for a user’s return to the site knowing whether they have previously bought something or whether they may need support to complete a service transaction.

_hjRecordingLastActivity This should be found in Session storage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session Analytics
_hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session Analytics
