Cookie Policy

Our websites (our “sites”) use cookies to distinguish you from other users. This helps us to provide you with a good experience when you browse our sites and also allows us to improve our sites. By continuing to browse our sites, you are agreeing to our use of cookies.

A cookie is a small file of letters and numbers that we store on your browser or the hard drive of your computer if you agree. Cookies contain information that is transferred to your computer’s hard drive.

We use the following cookies:

Strictly necessary cookies. These are cookies that are required for the operation of our sites and use of their features. They include, for example, cookies that enable you to log into secure areas of our sites. Without these cookies, services you have asked for, like shopping baskets or e-billing, cannot be provided.
Analytical/performance cookies. These allow us to recognise and count the number of visitors and to see how visitors move around our sites when they are using them, for instance which pages users go to most often, and any error messages received. All this information is aggregated and anonymous. This helps us to improve the way our sites work, for example, by ensuring that users are finding what they are looking for easily.

Functionality cookies. These are used to recognise you when you return to our sites and remember the choices you make. This enables us to personalise our content for you, greet you by name and remember your preferences (such as your user name, language or the region you are in). These cookies can also be used to remember changes you have made to text size, fonts and other parts of web pages that you can customise.

Targeting cookies. These cookies record your visit to our sites, the pages you have visited and the links you have followed. These cookies are used to deliver adverts more relevant to you and your interests and are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of the advertising campaign. They are usually placed on our sites by advertising networks with our permission. They remember that you have visited a website and this information is shared with other organisations such as advertisers.

We use a third party marketing automation tool called Pardot to set cookies.

Pardot tracks visitor activities on our website by setting cookies on their browsers. These cookies are set in order to remember preferences when an individual returns to our site, such as form field values. We also set a cookie for Pardot users who are logged into Pardot’s app, which allows us to maintain the login session and remember table filters.

What are the names of the cookies and what are they for?
Pardot sets three cookies:

Visitor Cookie: The visitor cookie includes the name “visitor_id” together with a unique identifier for the visitor, e.g.: “visitor_id1234”. This cookie is set by our tracking code on all visitors.
Opt In Cookie: We use the persistent cookie named “pi_opt_in” to stay in compliance with the “Do Not Track” initiative.
Pardot App Session Cookie: The session cookie named “pardot” is only set if you’re logged into Pardot’s app as a user (i.e. prospects will not have this cookie set).

What does this mean for you?
Visitors that have “do not track” settings enabled on their browser will not have their activities tracked while on our site.

To comply with the EU privacy directive, tracking opt-in can be enabled in your Pardot account by country. Visitors to our website from selected countries will receive a message at the top of the landing page on their first visit requesting permission to track their activities. More details are available in Tracking Opt-in by Country. If you click “do not track”, a small cookie is placed on their browser that signals to Pardot not to record or remember any of their activities while on our site.

Visitors that do not have “do not track” settings enabled in their browser and do have JavaScript enabled will have their page views and other activities tracked on Pardot landing pages and pages on our website that include Pardot tracking code.

With tracking enabled, visitors should not notice anything out of the ordinary other than the fact that we will “remember” the data they submit through a Pardot form. For example, their email address will be prefilled when they return, fields that were already completed will not display again unless they’re set to “always display” in the form, and there may be new conditional fields displaying that the visitor had not viewed before.

What domains do we set cookies on?

We set the cookie on the tracker (CName) and Pardot domains, so for example,, and also the root, *

Do the cookies expire?

The cookie duration is set to 10 years.

Do the cookies store any personal information (encrypted or otherwise)?

No. Pardot cookies are simply a numeric identifier that allow us to recognize repeat visitors, and have no functionality outside the Pardot system.

How would someone stop being tracked?

Pardot relies on being able to set cookies on users’ browsers. If cookies are disabled (generally or selectively), or if a browser extension (such as Ghostery) is enabled, Pardot cookies may not be set properly and prospect activity may not be tracked. For Pardot users’ logins to remain active, cookies must be enabled and any cookie-blocking extensions must be disabled for
