About this component

The cookie banner is a notification banner  at the top of all site pages. It gives users the option to accept or reject non-essential cookies. You should use it in combination with the cookie page pattern.

Users will see the cookie banner every time they access your website or service until they:

  • accept or reject cookies using the options in the cookie banner, or
  • save their cookie preferences on your cookie settings page

The term ’cookies’ on this page refers to:

  • browser and HTTP-only cookies
  • HTML5 local storage
  • service workers
  • any other technologies you use that store files on a user's device

Confirmation message

When a user has accepted or rejected cookies:

  • the cookie banner changes to a confirmation message and is not shown again
  • a cookie is set that remembers the user’s choice for 1 year

Sample HTML

<div id="cookie-confirm" class="ds_notification  ds_notification--cookie-success  ds_reversed  js-confirm-cookie-content" data-module="ds-notification">
    <div class="ds_wrapper">
        <div class="ds_notification__content">
            <div class="ds_notification__text">
                <h2 class="visually-hidden">Information</h2>

                <div class="ds_notification__text">
                    <p>Your cookie preferences have been saved. You can <a href="/cookies/">change your cookie settings</a> at any time.</p>

                <button class="ds_notification__close  js-close-notification" type="button">
                    <span class="visually-hidden">Close this notification</span>
                    <svg class="ds_icon  ds_icon--fill" aria-hidden="true" role="img"><use href="/assets/images/icons/icons.stack.svg#close"></use></svg>

When to use this component

Use this component if your website or service sets any cookies on a user’s device.

You must:

  • inform users about any cookies that you set on their device
  • allow users to reject any cookies that are not essential

If there is more than one notification banner on a page, the cookie banner should appear first.

Why we use this component

The cookie banner component you meet data protection legislation including:

  • Privacy and Electronic Communications Regulations (PECR)
  • General Data Protection Regulation (GDPR)

PECR asks that websites:

  • say what cookies will be set
  • explain what the cookies will do
  • get consent from users to store cookies on their devices


This component is currently experimental because we need more research to validate it. 47%+ of all users on interacted with this pattern in September 2021. But we also know from a survey carried out in 2019 and 2020 that many users have become blind to cookie notices.

Using that user survey and desk-based research, we set these rules for the new cookie banner. The cookie notice and cookie settings page should:

  • be non-intrusive across all devices
  • ensure that users know that they need to accept essential cookies
  • make it clear that we need the user’s consent to use cookies
  • show users how cookies help them to get the most out of a site
  • never use ‘dark patterns’ that trick users, such as where clicking ‘x’ accepts cookies
  • enable users to have control over cookie preferences for non-essential cookies

Website analytics

You can track clicks on links in the cookie banner using the data-banner data attribute. You can also record against the original page path the click URL, the click text or a data attribute for button clicks.

The Design System’s ‘tracking’ script adds the data attributes.
