What is the purpose of cookies?

Cookies make the interaction with frequently-visited websites smoother and faster – for no extra effort on your part.  Websites use cookies mainly because they save time and make your browsing experience more efficient and enjoyable, but they can also use cookies for the purposes of collecting behavioural and demographic information about their users.

What are ‘cookies’?

‘Cookies’ are small text files that are stored by the browser (e.g. Internet Explorer or Safari) on your computer or mobile phone. You can think of cookies as providing a ‘memory’ for the website, enabling it to recognise a user and respond appropriately. Each website can only access cookies related to that specific website. Websites can contain elements from multiple third parties in order to provide different services or functionality. Therefore when you visit a website, your browser may receive cookies from several sources.

There are two different types of cookies:

Session cookies – these are temporary and are erased when you close your browser at the end of your web session. The next time you visit that particular site it will not recognise you and will treat you as a completely new visitor as there is nothing in your browser to let the site know that you have visited before.

Persistent cookies – these remain on your hard drive until you erase them or they expire. How long a cookie remains on your browser depends on how long the visited website has programmed the cookie to last.

How does use cookies?

A visit to a page on may generate the following cookies:

Anonymous analytics cookies

Every time a user visits our website, web analytics software provided by a third party generates an anonymous analytics cookie. These cookies record data about how you interact with and use the site. Your browser will tell the site if you have these cookies, and if you don’t, it generates new ones. This allows us to track how many individual unique users we have, and how often they visit the site. These cookies cannot be used to identify individuals; they are used for statistical purposes only. This allows us, for example, to tell which pages are the most visited at any one time.

Market Research Cookies

We use third parties to provide some of the functionality on our website. These third parties, and their partners, can place market research cookies on your browser. These cookies count how frequently you have accessed our website and enable the evaluation of the success of particular marketing programs by collecting aggregate data across multiple websites.

Targeted Advertising Cookies

Third-party providers, and their partners, may also place cookies on your device to help facilitate online behavioural advertising. These cookies help advertisers identify users who are likely to be interested in their products or services based on what their browsers or devices share online. These cookies also keep track of how many ads each user has seen.

How do I turn off cookies?

It is usually possible to stop your browser accepting cookies, or to stop it accepting cookies from a particular website.

All modern browsers allow you to change your cookie settings. These settings will typically be found in the ‘options’ or ‘preferences’ menu of your browser. In order to understand these settings, the following links may be helpful, otherwise you should use the ‘help’ option in your browser for more details.

Some third-party providers, such as social sharing tools, may also use non-cookie technologies, such as statistical IDs. Please keep in mind that your web browser may not permit you to block the use of these non-cookie technologies, and the browser settings that block cookies may have no effect on such techniques. If the third-party provider uses the non-cookie technologies for interest-based advertising, you can opt out at Please note the industry opt out only applies to use for interest-based advertising and may not apply to use for analytics or attribution.
