This is a data-driven decision, and the Service Manual simply lists the minimum browser support that a government service should cater for. If you are a service team, does this mean you can stop supporting IE11 users from now? No, it doesn't. With Microsoft migrating IE11 users to their Edge, they will improve both security and overall web performance for these remaining users. This makes IE11 significantly less secure than other browsers like Microsoft Edge and Google Chrome. It isn't considered a 'modern browser' (a browser that automatically updates approximately every 4-6 weeks) as its updates are tied to the operating system updates (apart from iOS, iPadOS and Macintosh Safari that are currently the exception to this rule). IE11 was first released in October 2013, so it is coming up to 9 years old. We expect this to drop dramatically after the 15 June because a vast majority of IE11 visitors were using Windows 10 - so will be automatically upgraded to Edge. In April 2022 GOV.UK had 390,000 visitors who used IE11 - 0.65% of the total visitors. Beyond this point, Microsoft will be gradually migrating IE11 users on Windows 10 to their newer browser, Edge. This also happens to coincide with the announcement from Microsoft that IE11 was retired on 15 June 2022. Why we're making the change nowĪs of June 2022, Internet Explorer 11 (IE11) dropped below the monthly 95% threshold that's required to keep it on the Service Manual minimum browser support table. It’s updated in January and June every year. This list in the table is based on usage statistics for GOV.UK and represents approximately 95% of the most popular browsers. This is a data-driven process so it's as inclusive as possible to users of GOV.UK. The reasons these changes occurred is due to our rule that we only support the browsers the top 95% of people use. The last Internet Explorer change to the Service Manual was in June 2018, when we changed our testing requirements for Internet Explorer 8, 9 and 10.

This page gives service teams an idea of the minimum browser support their service should support. We constantly monitor the GOV.UK analytics browser stats and every 6 months we update the ‘ Designing for different browsers and devices ’ page in the Service Manual.
