Short answer: in the UK a child's first phone has three free layers, and most parents use one. The network's 18+ content lock (EE's is free and needs a credit-card age check to remove), the phone's own controls (Screen Time on iPhone, Family Link on Android), and each app's own settings. Set them in that order, then test on the child's phone.

Why UK parents get a different answer

Most parental-controls guides are written for the US. Two things are different here, and one of them is free money left on the table.

The first is the network layer. On EE the 18+ Content Lock is a free network-level filter, switchable by text (STRICT or MODERATE to 150), online, by phone or in store with photo ID, and turning 18+ content back on requires a credit-card age check [S115]. Nobody sells that to you; it comes with the SIM. The US equivalents are structured differently: Verizon Family's free tier covers location, Safe Walk with SOS and call and text review, and puts Parental Controls behind the paid Plus tier [S106]; AT&T Secure Family needs iOS 16 or Android 13 and up [S108].

The second is that the phone-level settings are region-flagged. Apple states "Age varies by country or region" [S031][S268]; Google writes the qualifying age as "13 (or the applicable age of consent in your country)" [S255]. A US guide can describe a screen that your child's phone, on a UK account, does not show.

The question UK parents actually ask, on Mumsnet, is not "which app" but "how": "Ideally I would like to have a timer on her phone so it turns on and off at particular times" [S015]; "if she wants to download any apps that I must give permission first" [S015]; and the house rule that comes up over and over: "Phones only charge in the kitchen. No phones in bedrooms" [S016].

Prices are the vendors' own list prices as read on 2026-09-09. Only EE's lock is sourced in the kit; other UK networks were not verified and are not described.

What you'll have when you're done

  1. The network's 18+ lock confirmed on for the child's SIM, and confirmed that removing it needs an adult's card [S115].
  2. The phone locked down screen by screen: parent passcode first, purchase approval, daily limits, content restrictions, deletion blocked [S012][S031][S270][S013].
  3. YouTube, Instagram, Snapchat and Roblox configured one at a time with each platform's own free tool [S114][S113][S253][S258].
  4. Proof the limits hold, from a test on the child's own phone, on WiFi and on 4G [S269][S169].
  5. The UK version of the one-page family agreement, with the school's own phone rules written into it, signed by both of you [S014].

The three layers, in order

TL;DR

  • Layer 1, the network: check the 18+ content lock on the child's SIM. On EE it is free, text STRICT or MODERATE to 150, credit-card check to remove [S115].
  • Layer 2, the phone: passcode first, then approval, limits, content, deletion block. Screen Time [S012][S031] or Family Link [S013][S266].
  • Layer 3, the apps: YouTube, Instagram, Snapchat, Roblox, each with its own tool [S114][S261][S253][S267].
  • Test on the child's phone, then with WiFi off [S269][S169]. Sign the UK agreement, school rules included [S014].
  1. Before anything: write down the exact OS version and the account country. Apple's screens differ by region and by version [S031][S268]; Google's qualifying age depends on the country [S255]. Two minutes now saves an evening of "my screen doesn't look like that".
  2. Layer 1, the network. On EE: Content Lock is a free 18+ filter; switch it by texting STRICT or MODERATE to 150, online, by phone or in store with photo ID; with it on, 18-rated content shows a blocking page and "you'll need to complete a credit card age check" to view it [S115]. EE's page documents the switch, not the out-of-box default, so check the child's account rather than assuming. On any other network, ask them the question directly and in writing. Done when: you know it is on, and you know a child cannot turn it off without an adult's card.
  3. Layer 2, iPhone. Settings → Screen Time → Family → [child] → App & Website Activity → Turn On → Lock Screen Time Settings, four digits entered twice, with Passcode Recovery on [S012][S273]. Then Ask to Buy, so "If you decline the request, no purchase or download will take place" [S101]. Then Downtime and App Limits [S012]. Then Content & Privacy Restrictions, sub-screen by sub-screen [S031], including iTunes & App Store Purchases → Deleting Apps → Don't Allow [S270]. Communication Safety is on by default for under-18 accounts; you do not pay a subscription for it [S102][S100].
  4. Layer 2, Android. Check which of Google's two systems the phone offers: on-device controls with no child account, or Family Link for several devices [S266]. To supervise an existing account you must be 18 or over with the child and their device present [S105]. Set app approval, Daily limit, Weekly schedule and App limits from your own phone before the child holds theirs again [S013]; the web filter lives under Controls → Google Chrome and Web, where "Only allow approved sites" takes whole domains [S265]. Then Developer Options and USB debugging off [S275].
  5. Layer 3, the apps. The phone settings do not reach inside the apps. A supervised YouTube account makes you pick a content setting yourself [S114]. Instagram Teen Accounts protect 13-to-17-year-olds by default, and 13-to-15-year-olds cannot loosen them without a parent [S113][S261]; a supervising parent cannot read the messages but can see who the teen messaged in the past seven days [S261]. Snapchat's Family Center does not show the content of private conversations [S253]. Roblox has required facial age checks for chat globally since January 2026 [S258][S267]: decide whether chat stays on at all, and write it down.
  6. Test, on the child's phone. Open screentime.report and tap the app you limited; if the page does not load, the block is on; give it a few minutes after any change [S269]. Then turn WiFi off and test again: controls set on the device and on home broadband "won't work if they use 3G, 4G or 5G, public WiFi or log onto a friend's connection" [S169].
  7. Sign the UK agreement the same evening. Downloads need a yes, when and where the phone works, where it charges overnight, and the school's own phone rules written in: "incorporate the school's rules" is the step most guides skip [S014]. Write the IMEI on it, and the loss plan: call the network with the account and the IMEI, tell the police the IMEI, change the passwords the phone could reach [S279][S018]. It is a household document, not a legal contract.

The hard part: what this page does not know about the UK

Only EE's lock is sourced. O2, Vodafone, Three and the virtual networks all publish something, but none of them met the kit's sourcing standard on the day it was checked, so nothing about them is printed here. Ask your own network the one-line question in step 2 and keep the answer.

The law is named, not interpreted. The UK Online Safety Act collection [S254] and the ICO Children's Code [S028] are linked so you can read them. Whether either creates a duty for you is a question for a qualified adviser, not for a guide.

WhatsApp, the app UK kids actually use, is a gap. The kit prints neither "no parental controls" nor "now has them", because the page that would settle it could not be read at verification time. WhatsApp's own Help Centre, read today, is the only answer we trust.

And the general limit, from the NSPCC's Luke Savage: "There are limitations to parental controls. They're not perfect - children can bypass them if they're clever enough." [S283] The test in step 6, repeated monthly, is the honest reply.

Questions parents actually ask

Is the network content lock already on, and does it cost anything?

On EE, Content Lock is a free network-level 18+ filter; you can switch it by texting STRICT or MODERATE to 150, and "you'll need to complete a credit card age check" to view 18-rated content with it on [S115]. EE's page covers switching it, not whether a new child SIM ships with it on, so check your own account. We only verified EE; ask any other network the same question directly: "Is there a network-level filter on this account, is it on, and what does it cost?"

Screen Time and Family Link are free. What does a paid guide add?

The order, both platforms, and the test. The settings are free and documented by Apple [S012][S031] and Google [S013][S266]; what parents in UK forums ask for is the sequence: "Ideally I would like to have a timer on her phone so it turns on and off at particular times" [S015]. The kit puts the passcode step first, the deletion block second, and a block test at the end, then a signed agreement with the school's rules folded in [S014].

The screens on my child's phone don't match the instructions. Why?

Almost always version or region. Apple states "Age varies by country or region" and documents the request-for-more-time flow for iOS 26 and iPadOS 26 only [S031][S268]. Google writes the qualifying age as "13 (or the applicable age of consent in your country)" [S255]. Write down the exact OS version and the account country before you follow any guide, including this one.

Does this make us compliant with the Online Safety Act or the Children's Code?

No, and neither this page nor the kit claims that. Both are named and linked, the UK Online Safety Act collection [S254] and the ICO Children's Code [S028], and interpreted by nobody here. Whether either creates a duty for you, in your situation, is a question for a qualified adviser.

What about WhatsApp?

Named honestly as a gap. The kit says neither "WhatsApp has no parental controls" nor "WhatsApp now has them", because the page that would settle it could not be read at verification time. Open WhatsApp's own Help Centre and read what it says for the UK today.

This isn't for you if: you're looking for a setting described as unbeatable (none of the sources this kit relies on claim one exists), you want continuous monitoring as a paid service, or you want someone to interpret the law for you. This kit uses only what the phone already has, tested once, with a habit to keep checking it.
This kit is information, not professional advice. It organises your questions and your settings. It does not replace a professional. For anything past this page's scope, see the linked official pages (FCC, FTC/COPPA, ICO Children's Code) and consult a qualified professional if needed. Settings screens change with operating-system updates; check anything that matters against the platform's own page. Nothing here interprets any law. No refunds on this digital download.
