Page not found pages
Experimental

This pattern is currently experimental because more research is needed to validate it.

A page not found tells someone we cannot find the page they were trying to view. They are also known as 404 pages.

When to use this pattern

Use a page not found if someone is trying to view a page that does not exist. This happens if someone:

  • selects a link or button that takes them to a page that does not exist
  • types or copies a web address for a page that does not exist
  • types or copies a web address incorrectly

Test all links and buttons to make sure they work. Remember to do the hard work to make it simple.

Make sure any web addresses in your service, letters, forms and on GOV.UK are for pages that exist or redirect to pages that exist.

How it works

The page should have:

  • ‘Page not found – service name – GOV.UK’ as the page title
  • ‘Page not found’ as the H1
  • contact information, if it exists and helps meet a user need

Contact information should either:

  • be a link to a specific page that includes numbers and opening times
  • include all numbers and opening times

The content should be clear and concise, not blame the user.

Do not use:

  • breadcrumbs
  • technical jargon like 404 or bad request
  • informal or humorous words like oops
  • red text to warn people

Research on this pattern

More research is needed to find out if people:

  • can fix the problem on their own
  • understand what has happened
  • understand the content and if there is anything missing
