The school phone ban: what it will and won't change

When your child goes back this term the phone rules will have changed. From 1 September every state funded school in England has to work to statutory guidance saying that schools should be mobile phone free environments by default. Plenty of schools already were. What is new is that it is no longer a matter of local preference. What a parent wants to know is whether it will change anything about how their child actually is, and on that there is now real UK evidence rather than assertion, most of it published in the last eighteen months.

What changes on 1 September

Section 36 of the Children's Wellbeing and Schools Act 2026 came into force on 29 June and requires the head teacher or proprietor of a school in England to have regard to the Secretary of State's guidance on pupils having mobile phones and other personal interactive communication devices during school hours. The guidance itself became statutory the same day, and schools are expected to be following it from 1 September (Department for Education, 2026). Its central line is that all schools should be mobile phone free environments by default, and anything other than that should be by exception only. In practice that means no access during lessons, between lessons, at break or at lunchtime. There are exceptions written into the guidance rather than bolted on afterwards. Schools have a duty under the Equality Act 2010 to make reasonable adjustments for disabled pupils, and allowing a disabled pupil access to their phone where the nature of their disability requires it may count as one. Pupils with medical conditions are covered, with continuous glucose monitoring linked to a phone given as the worked example. Sixth formers may be permitted access at certain limited times and places. Devices provided by the school itself sit outside the requirement altogether.

The largest UK study found no difference in wellbeing

The SMART Schools study, funded by the National Institute for Health and Care Research, recruited 1,227 pupils aged 12 to 15 across 30 English secondary schools: 20 that did not permit recreational phone use and 10 that did. The primary outcome was mental wellbeing, measured with the Warwick-Edinburgh Mental Well-Being Scale. The mean score was 47 out of a possible 70, and there was no evidence of a difference between the two types of school, with an adjusted mean difference of -0.48 and a confidence interval running from -2.05 to 1.06 (Goodyear et al., 2025). The authors' own conclusion was blunt: there is no evidence that restrictive school policies are associated with better mental wellbeing or with overall phone and social media use, and the policies require further development in their current form. That is not an argument for phones in classrooms. It is an argument against expecting the ban, on its own, to do anything for your child's mood.

The bans do work, on the hours they cover

The same study found that pupils in restrictive schools used their phones 0.67 hours less and social media 0.54 hours less during the school day, roughly 40 and 32 minutes. So the policies do what they say. The finding that matters is what happened either side of that: there was no evidence of any difference in phone or social media use when the researchers looked at the whole weekday, or at weekends (Goodyear et al., 2025). The time comes back after the bell. Meanwhile it was total use, not school hours use, that tracked with how children were doing. Higher phone and social media use across the day, the week and at weekends was associated with more depression and anxiety symptoms, more problematic social media use, and with poorer sleep, less physical activity, worse classroom behaviour and lower attainment. This was a cross-sectional study, so it cannot tell you which way the arrow points; a low teenager may reach for her phone more rather than the phone making her low. What it does show is that the variable associated with wellbeing is the one a school day policy leaves untouched.

Why restricting the school day is not enough on its own

The research team went back and asked people why. They ran 40 focus groups across seven secondary schools, four permissive and three restrictive, with 177 pupils, parents and staff. Both kinds of policy turned out to have positive and negative effects on wellbeing, working through health, connectedness, learning, a young person's sense of agency and resilience, and whether the environment felt safe and supportive. Which effects dominated depended heavily on the surrounding context of each school (Goodyear et al., 2026). Their conclusion was that anything aimed at phone use needs to sit inside a broader approach that covers both school and life outside it. A rule that operates for six hours a day, five days a week, thirty-nine weeks a year is a piece of that, not the whole of it.

What the ban is likely to be genuinely good for

A separate health economics analysis of the same study looked at 815 pupils across 20 schools and found the differences in quality of life and in wellbeing adjusted life years between restrictive and permissive schools were minimal. It did find that restrictive schools spent slightly less staff time on phones, the equivalent of 3.1 full time staff against 3.3, with an incremental cost difference of -£94 per pupil per school year, though the confidence interval crossed zero. The researchers' closing point was about how much time teachers spend managing phone use at all (Perry et al., 2026). That is the honest case for the policy: fewer arguments in corridors, and staff doing something other than policing pockets. Both are real gains. They are school improvements rather than mental health treatment, and it is fairer to everyone to describe them that way.

Children whose phone is doing a job

For most children the phone is a distraction and losing it for the day is a minor inconvenience. For some it is a coping strategy, and removing a coping strategy without putting anything in its place makes the day harder rather than easier. There is the anxious Year 7 who has been getting through the morning by texting home at break. There is the autistic young person who uses ten predictable minutes at lunch to reset before an afternoon of noise, and the child whose closest support at the moment is a friend at a different school. If that describes your child, the useful move is a conversation with the school before term starts rather than after the first bad week. Ask what the policy actually says, what the process for an exception is, whether a reasonable adjustment applies, and what a child who is struggling at lunchtime is meant to do instead. Schools have been given room in the guidance for exactly this. Most will use it if asked directly, and a request made in the last week of August is easier to accommodate than one made in October.

The part that is still yours

If the association with wellbeing sits in total use and total use is barely moved by school policy, then the evenings, the weekends and the school holidays are where any real change happens, and none of that is the school's to manage. Two things matter more than a screen time number. The first is where the phone sleeps: out of the bedroom overnight, charging somewhere else, is the single change most likely to protect sleep, and sleep is upstream of a great deal else. The second is knowing what the use actually is. Forty minutes messaging three close friends is not the same as forty minutes scrolling strangers, and the totals will not distinguish them. Ask what she is looking at rather than only how long she was on it. Expect the school's new rule to change the shape of the school day, and expect nothing from it at seven in the evening.

One last thing to separate out. If your child is anxious about the new rule to the point of not wanting to go in, or if their mood has been low for more than a few weeks, or if the phone has become the thing every argument in the house is about, the policy is not the problem you are dealing with.
