We use cookies to make sure you always see the best possible version of our website. They’re how we personalise your visit and how you can get to the pages you use more quickly.

They’re text files formed by small bits of data, which download to your device when you visit a website. When you re-visit that website – or any other website that recognises that cookie – your device sends it back again.

Cookies allow a website to recognise a user's device and serve up more relevant content. They also help keep your device – and our systems – more secure.

We use four types of cookies. Some you have to use, others you don’t. The four types are: http://www.ico.org.uk/ http://www.iabuk.net/

These cookies are essential in order to enable you to move around the website and use its features, such as accessing secure areas of the website. Without these cookies, services you have asked for, like shopping baskets or e-billing, cannot be provided.

These cookies collect information about how visitors use a website, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies don't collect information that identifies a visitor. All information these cookies collect is aggregated and therefore anonymous. It is only used to improve how a website works.

These cookies allow the website to remember choices you make (such as your user name, language or the region you are in) and provide enhanced, more personal features. For instance, a website may be able to provide you with local weather reports or traffic news by storing in a cookie the region in which you are currently located. 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. They may also be used to provide services you have asked for such as watching a video or commenting on a blog. The information these cookies collect may be anonymised and they cannot track your browsing activity on other websites.

These cookies are used to deliver adverts more relevant to you and your interests. They 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 by advertising networks with the website operator's permission. They remember that you have visited a website and this information is shared with other organisations such as advertisers. Quite often targeting or advertising cookies will be linked to site functionality provided by the other organisation.

If you wish to opt out of any of the above cookies you will need to change your browser settings. For further details please visit the relevant provider –
