A small UK site. A ranked list, a parent script, a school kit, the research. Made for UK parents who would rather wait.

What "Knock" means

Your child wants a phone. It can feel like half the class already has one, and they've started to mention it. You're not dead against it. You've just got a bad feeling about handing a ten-year-old the whole internet, and no spare evening to work out whether the feeling is right.

Here's the thing a phone quietly takes, once you slow down enough to name it. Not the big stuff. The afternoon your child used to fill themselves: going round, knocking on, seeing who was about, coming home when they got hungry. Now they watch the group chat arrange it without them. That knock on the door is the verb this site is named for.

We're not trying to drag all of 1995 back. Childhood wasn't pure then either. But a few things are worth holding onto: Snake in a pocket, knocking for a friend, being daft without it being filmed, working out who you are with nobody watching. That's what the rest of the site is built around.

What Knock is, plainly

Knock is a UK editorial site on simple phones for children. It launched in May 2026, written and edited by Simon Tomlinson, who works in UK public-health communications by day and writes Knock in the evenings.

We're not an agency, a consultancy or a charity. We're a small editorial project, run by one person, with no staff. We're new. We're not phone reviewers either. What we've done is read what the named UK and US tech reviewers say (Wired, The Verge, GSMArena, TechRadar, Tech Advisor, Trusted Reviews, Stuff, Engadget), what UK parent campaigns like Smartphone Free Childhood and Wait Until 8th say in public, and the primary sources on every statistic. Then we've pulled it together for parents and teachers. Full list of who we read is on /editorial-standards. The site earns a small commission on Amazon UK buy buttons; that's the only income. Full disclosure at /affiliate-disclosure.

Knock does not consult one-to-one with UK families and does not claim to. The script and the kit are built from the public framing of campaigns such as Smartphone Free Childhood and Wait Until 8th, from named press coverage, and from Jonathan Haidt's framework in The Anxious Generation. The job of the site is to gather the practical guidance and the research in one place, so that UK parents who would rather wait can find both without searching the wider web.

Why it exists

The same question comes up in school WhatsApp groups, on after-school walks and in named UK press coverage of these campaigns: what phone should I actually buy, and what do I say. By May 2026 the case for delaying a first smartphone had been built by the Smartphone Free Childhood movement (which reports more than 500,000 UK parents organised in regional WhatsApp groups), the Anxious Generation framing was in the wider conversation, and UK schools were rolling out the Department for Education's February 2024 phone guidance. What was missing was a single UK site where the practical answers lived: ranked phones at UK retailers, a parent script, a school letter template, and the research with citations.

The proposition is grounded in a piece of behaviour-change theory: one family acting alone against the year-six WhatsApp group can feel mad; three families acting together feels reasonable. The kit on the site is built so three families can switch together in the same fortnight.

What Knock does

Knock ranks the simple phones available at UK retailers drawn from published UK and US tech reviews of basic phones (Wired, The Verge, GSMArena, TechRadar, Tech Advisor, Trusted Reviews, Stuff, Engadget) and manufacturer specification sheets. The public positions of UK parent campaigns (Smartphone Free Childhood, Wait Until 8th) inform the editorial framing; Knock does not claim a body of private parent testimony of its own. The site writes the parent script for the kitchen-table conversation, writes the school letter template for the head of year, and cites the research behind every position to its primary source. Every UK price is checked at the retailer on publish day. Phone recommendations are reviewed best-effort quarterly, with the date stamped on the page.

Knock does not stock phones. It does not run a paywall. It does not write sponsored content. It does not put affiliate links on the research, the switching kit or this page. Those three are the trust layer. Everything else is honestly transactional and disclosed at the top of every page that carries a buy button.

Editorial standards

Short enough to fit on one page. Apply to every word on the site.

1. Every statistic links to its primary source. If the source isn't visible, the claim doesn't print.
2. The mental-health evidence on smartphones is correlational, not causal. The site says so explicitly on every page where the evidence is discussed. Ofcom, the Department for Education, Parentkind and Ipsos are cited by name.
3. Affiliate programmes and the commission they pay are named on the disclosure page. Commission rates do not change the order of the phones list.
4. Phone recommendations are reviewed best-effort quarterly, with the date stamped on the page, against UK retail availability and price. Where a phone drops off the list, the reason is stated on the page.
5. Knock does not use stock photography of children. It does not call your child "kiddo", "little one" or "your tiny human".
6. UK school phone-free pilots are described as small qualitative studies of pupils with named academic partners. They are not described as population studies.
7. If the site makes a mistake, the correction lives on the page where the mistake landed, and anyone the site has emailed about that page is emailed about the correction.

Sources Knock draws on

Smartphone Free Childhood, the UK parent movement organised by Daisy Greenwell and Clare Fernyhough. Wait Until 8th, the US pledge that has reached UK families. After Babel, Jonathan Haidt and Zach Rausch's continuing work. The Department for Education's February 2024 guidance and the gov.uk policy page that followed. Ofcom on UK children's media use. Parentkind on UK parent attitudes. Ipsos UK on adult views on first-smartphone age. The published UK secondary-school phone-free pilots that have reported their findings. None of these sources are partners; none of them know Knock exists; Knock cites them because their work is the foundation the site is built on.
