Prime Minister Sir Keir Starmer is expected to ban under-16s from major social media platforms including TikTok, Snapchat and Instagram.
The government will also stop children being able to livestream on “safer” sites, and stop them being able to talk to strangers on gaming apps.
Ministers are considering whether to impose social media curfews for children, but further details will not be unveiled until next month.
Australia introduced the world’s first outright ban on social media for under-16s in December 2025 and Whitehall sources are describing the UK’s scheme, to be unveiled by Sir Keir on Monday morning, as “Australia-plus”.
“This is a choice about whose side we’re on: families across the country, or a status quo that isn’t working,” Sir Keir said.
He would, he said, “call time on a system that’s failing our kids”.
While a government consultation has found a majority supports a social media ban for under-16s, some campaigners have said such sweeping measures would cause more problems.
The Sunday Times reported, external the prime minister was set to announce a ban covering the same 10 platforms now prohibited for under-16s in Australia: TikTok, Snapchat and Instagram, but also YouTube, Reddit, Twitch, X, Threads, Facebook and Kick.
It said the UK would “go further” than Australia with additional measures including curfews for older teenagers and restrictions on AI chatbots.
Sir Keir said: “How we keep kids safe online is one of the biggest debates of our time. As a dad, I know every parent wants their child to grow up safe and happy.
“This is a choice about whose side we’re on: families across the country, or a status quo that isn’t working.
“People rightly expect action, and this government will always stand up for parents and put children first.
“That’s why we will call time on a system that’s failing our kids and take bold action to give every child the best possible start in life.”
