Cookies Policy

A cookie is a small piece of data that is sent from our web server to your browser when you visit the site. It is stored on your hard drive. Internet browsers normally accept cookies by default, but it is possible to set a browser to reject cookies.

Zero Burden Services sites comply with guidance recently issued by the relevant Data Protection legislation.

Our cookies

Cookies allow us to recognise devices and track how our visitors use Zero Burden We use cookies that are essential for you to navigate the site or provide you with basic website features. Data collected from some cookies helps us enhance the performance of the site and offer you a better user experience We will not use any of this data to identify you personally, it is used only to monitor and improve the site.

There are several types of cookie that are used to keep track of information needed by a site user as they travel from page to page within a website.

First-party cookies

Cookies can be used to track internet activity after the user has left a website. These are normally facilitated by organisations external to the website being visited and are generally known as ‘third-party’ cookies. They usually have a long lifetime with several months being quite common. They are ‘harvested’ and ‘refreshed’ whenever the user visits a page where the same or a similar cookie is being used.

Google Analytics

We currently use Google Analytics & Hubspot to measure and analyse visitor information related to our web site. For that purpose, your IP address, Internet traffic data and data on your browser type and PC are collected using several cookies (_utma, _utmc, utmb, utmz):

  • _utma is used to identify first-time site (‘unique’) visitors vs. returning visitors. It expires after two years
  • _utmc identifies unique visitors vs. returning visitors but expires when you close your browser.
  • _utmb is used for general visitor tracking and expires after 30 minutes.
  • _utmz tracks source visits (the origin of the visit). It expires after six months.

Third-party cookies and microsites

The domain specified in the cookie relates to the cookie’s owner (the “party”), who has set the cookie. Zero Burden cookies will have the site domain specified in a cookie. These are first-party cookies.

The site sets a number of cookies. These are used to analyse our members’ browsing of the site for future improvements and to provide certain useful functions such as storing your login details.

The data is not used to identify individual members. See our third party cookies policy for further information. A third-party cookie is set when you visit a site but the domain named in the cookie sent to your computer is not the same as the website.


Microsites are collections of webpages created as a discrete entity within a larger website. Microsite pages are usually related by content on a similar topic, such as Zero Burden Service’s sustainable business microsite.

They often have a different domain name from the parent website and content for microsites may be provided by specialist organisations. The site hosts several microsites on our servers and links to many others hosted by our corporate partners. Zero Burden Service does not control dissemination of third party cookies.

Member login

The .ASPXAUTH (Member login) cookie holds login information regarding the current session from a user on the site. It is used for quick reference and is encrypted by .net to ensure security.

Session Cookie

The ASP.NET_SessionId cookie is related to the client login cookie. It is used by ASP.NET to create a session cookie that contains ‘session id’ and is required for everyone visiting the site. This helps to maintain security and to keep track of visitor data. It is a required cookie for forms where it allows the data entered to be processed.


iFrames are set up on some of our pages to present event and booking information. IRIS provides iFrames for this purpose and may present cookies.

External Media

We sometimes embed media content from external websites. The site pages with embedded media content, for example photos from flickr or videos from YouTube, may provide cookies from these websites. Cookies may also be presented by external providers of a share content service, such as digg or Twitter.

Rejecting cookies

Internet browsers normally accept cookies by default, but it is possible to set a browser to reject cookies. If this is done it is important not to exclude the benign and useful cookies. Choose an option that rejects all third party and long-lived cookies.
