It’s all in the detail

This Cookie Policy forms part of our Privacy Policy which can be viewed here

Our websites and apps use cookies and similar technologies to collect information about users’ activities, including browsing and purchasing behaviour. This includes information about pages viewed, products purchased and the customers’ journey around our apps and websites. Detailed information is set out in our Cookie Policy. We use the term ‘site’ to refer to websites and apps.


Cookie Policy



This policy applies to all Marks and Spencer Plc (“M&S”) owned and operated sites, both in the UK and in the international territories in which we operate. This includes M&S owned web pages which refer a user to M&S branded products and services which are provided by third party organisations.



Cookies are small data files which are placed on your smart phone, tablet, laptop or other device when you use sites. They are used to ‘remember’ when the same device returns to a site, to track activity via the device, or to identify a user as having come from another site. Some cookies are used just for the duration of your visit (“session cookies”) and others for an extended period (“persistent cookies”).

M&S sites use cookies and other similar technologies which also store or provide access to information stored in your devices including, web beacons, plug ins, APIs, and fingerprinting technologies which permit the identification and tracking of a device. For the purposes of this policy we use the term “cookies” to include all technology that stores or accesses information on a user’s device all of which are governed by the same legal rules.



In most cases cookies cannot be deployed without consent. When you first enter our sites, you will be shown a pop-up cookie notification banner. The banner informs the user that our site uses cookies and provides options on whether to accept all cookies, to reject all (except ‘essential’ ones) or to accept only certain types. When you click “Accept all Cookies”, you are consenting to non-essential cookies unless you have disabled them using your browser settings. An explanation of what we mean by the terms essential and non-essential cookies is set out in the section below.



Essential cookies

  • To improve the quality of our services and develop new ones.
  • To enable special site features such as widgets or embedded media files.
    These special features are not essential to the operation of the site but are intended to enhance user experience. They also allow us to develop and test new site features.
  • To Enable M&S to meet its contractual obligations to make payments to third parties when a product is purchased by someone who has visited our site from a site operated by those parties.


Show personalised content based on your interests, preferences or location

We use these cookies to improve the way our sites and mobile apps work so that we can personalise your experience and show you content which is most relevant to you. For example, a product or service may only be available in a particular location and may be more relevant to you depending on where you are, or we might show you certain products or services that we believe are most relevant to you based on your previous browsing or purchasing behaviour.

Some cookies can tell us if you have seen a specific advert, and when you saw it. This information allows us to measure the effectiveness of our online advertising campaigns and control the number of times you are shown an advert.

We also use cookies to measure the effectiveness of our marketing communications, for example by telling us if you have opened a marketing email that we have sent.
