Notification banner
This component is currently experimental because [more research] is needed to validate it.
Use a notification banner to tell the user about something they need to know about, but that’s not directly related to the page content.

disableAutoFocus | other | If you set type to success, or role to alert, JavaScript moves the keyboard focus to the notification banner when the page loads. To disable this behaviour, set disableAutoFocus to true. | |
titleId | other | The id for the banner title, and the aria-labelledby attribute in the banner. Defaults to govuk-notification-banner-title. | |
type | other | The type of notification to render. You can use only the success or null values with this option. If you set type to success, the notification banner sets role to alert. JavaScript then moves the keyboard focus to the notification banner when the page loads. If you do not set type, the notification banner sets role to region. |
When to use this component
A notification banner lets you tell the user about something that’s not directly relevant to the thing they’re trying to do on that page of the service. For example:
- telling the user about a problem that’s affecting the service as a whole (for example, delays in processing applications because of an emergency)
- telling the user about something that affects them in particular (for example, an approaching deadline they need to meet)
- telling the user about the outcome of something they’ve just done on a previous page (for example, confirming that an email has been sent)
When not to use this component
Use notification banners sparingly. There’s evidence that people often miss them, and using them too often is likely to make this problem worse.
If the information is directly relevant to the thing the user is doing on that page, put the information in the main page content instead. Use inset text or warning text if it needs to stand out.
Do not:
- use a notification banner to tell the user about validation errors - use an error message and error summary instead
- show a notification banner and an error summary on the same page - just show the error summary
How it works
Position a notification banner immediately before the page h1
. The notification banner should be the same width as the page’s other content, such as components, headings and body text. For example, if the other content takes up two-thirds of the screen on desktop devices, then the notification banner should also take up two-thirds. Read about how to lay out pages.
Use role="region"
and aria-labelledby="govuk-notification-banner-title"
(with id="govuk-notification-banner-title"
on <govuk-notification-banner__title>
) so that screen reader users can navigate to the notification banner.
Avoid showing more than one notification banner on the same page. Instead, combine the messages in a single notification banner. If the messages are too different to combine, only show the highest priority notification banner.
Notification banner headings
You can use <h3>
headings in the govuk-notification-banner__content
to help structure your content.
Avoid using headings for single-line notifications that do not need them.
Telling the user about a problem that affects the whole service
Use a ‘neutral’ blue notification banner if the user needs to know about a problem with the service as a whole.
For example:
- in a service that lets the user register or apply for something, they might need to know that it’s taking longer than usual to process applications because of an emergency
- in an account-type service, the user might need to know that the service will be down for scheduled maintenance

<NotificationBanner>

If your service is on GOV.UK and it’s affected by an emergency, ask your department’s content team to request a change to the service start page.
If your service is getting more demand than usual, check that you’ve set up There is a problem with the service pages and Service unavailable pages, and the wording is up to date.
Telling the user about something that’s happening elsewhere
Use a ‘neutral’ notification banner if the user needs to know about something that’s happening elsewhere in the service. For example:
- in a case working system, the user might need to know that there are new cases waiting for their attention
- in an account-type service, you might need to tell the user that there’s a deadline approaching or that a payment is overdue

Reacting to something the user has done
You can also use a notification banner to tell the user about the outcome of something they’ve just done - but they have not finished using the service, so it does not make sense to use a confirmation page.
Using a notification banner is unlikely to be the right approach in a linear service - for example, a service that lets the user register or apply for a thing. For a linear service, it will usually make sense to stick to the ‘one thing per page’ approach. Do not use a notification banner to tell users that they’ve finished using a linear service. Use a confirmation page instead.
Use the green version of the notification banner to confirm that something they’re expecting to happen has happened.

</NotificationBanner>
Since you’re using the notification banner to tell the user about the outcome of something they’ve just done, add role="alert"
so focus shifts to the notification banner on page load.
Remove a green notification banner when the user moves to a new page.
To make the green version of the notification banner accessible:
- use headings like ‘Success’ - so that you’re not relying on colour alone to convey meaning)
- use the same heading for green notification banners within the same service - so that you’re identifying components that work in the same way consistently
Research on this component
We need more research to understand:
- how common it is for users to miss important information in notification banners (including users of assistive technology, who might skip straight to the
h1
) - whether it’s sometimes helpful to allow users to dismiss notifications, and how to do this
