One editor behind the work.

By spring 2026, the UK conversation about delaying a child's first smartphone had matured. The Smartphone Free Childhood movement reported more than 500,000 UK parents in regional WhatsApp groups. Jonathan Haidt's The Anxious Generation had given a shared vocabulary. The Department for Education's February 2024 phone guidance was being rolled out across UK secondaries. A published UK secondary-school phone-free pilot had reported its findings. What was missing was a single UK site where the practical answers lived in one place: ranked phones at UK retailers, a parent script, a school comms template, and the research with citations. That's the gap Knock is written to fill.

Knock is not consulting; it is publishing. It does not advise individual families one-to-one and does not lab-test phones. It draws together the public framing of UK parent campaigns, the research, and the published UK and US tech reviews into a single editorial position, with the citations shown.

One piece of behaviour-change theory. Most parents already know it in their bones: a single family standing against a strong norm feels mad; a friendship group acting together feels reasonable. People are wired to lean toward what the people next to them are doing. So the conversation guide on the site is written four-up. Three families switching together in the same fortnight is, in named UK press coverage of families who have done this together, easier than one family switching alone.

One piece of evidence that isn't yet settled, said clearly: the science linking adolescent smartphone use to mental health is largely correlational. Knock cites Ofcom, Parentkind, Ipsos and the Department for Education by name, and never calls the science settled when it isn't. The precautionary case is strong enough to act on. The full position is on the risks page.

Knock is written by one editor. Long-form pieces are drafted, set aside, and re-read against the primary sources cited in each piece before publish. Statistics come from Ofcom, Parentkind, Ipsos, the Department for Education and peer-reviewed work where relevant. If a statistic is not in a cited source, it does not appear on the page. AI tools help reshape drafts and check for inconsistencies. They are never used to invent a claim, a quote or a parent story.

We're not phone reviewers. The reviews on Knock are drawn from what Wired, The Verge, GSMArena, TechRadar, Tech Advisor, Trusted Reviews, Stuff and Engadget have already written, plus manufacturer spec sheets. The public positions of UK parent campaigns (Smartphone Free Childhood, Wait Until 8th) and named press coverage shape the framing. Knock doesn't have a lab, doesn't pretend to, and doesn't have a body of private parent testimony of its own. The full list of who we read is on /editorial-standards. UK retail prices are checked at three retailers before publish, best-effort quarterly after that.
