Prevention or containment: 57% fear some teenage habits are already too ingrained to change
The UK is in a period of reassessment when it comes to protecting childhood. From legislation that tightens mobile phone restrictions in schools to renewed efforts to reduce high‑sugar and deep-fried foods in the canteen, public opinion is increasingly aligned around the need for intervention. The growing visibility of movements like ‘Smartphone Free Childhood’, recently explored by the BBC, also points to a broader cultural shift in attitudes towards children’s smartphone use. The question for many people is no longer whether children’s relationships with technology and healthy eating need addressing, but whether enough is being done at a pace that will change course for the next group of school starters.
Our latest research suggests that there is rising concern that some behaviours may already be too deeply entrenched, particularly among older children, and that any regulation in schools will have minimal impact. There is growing acknowledgement that expecting schools alone to do the heavy lifting is insufficient; the pivot needs to come from both the home and school environments in order to make a lasting difference.
Schools are seen as a support, but in no way the full solution
With new government laws coming into force to ban phones in schools, public attitudes towards school‑led interventions are largely supportive. Half of the public see mobile phone restrictions in schools as a necessary safety measure, while over a quarter view them as a welcome source of added support for parents.
There is recognition that these policies can help reset expectations at home. When boundaries are established at a school or national level, parents feel less isolated when enforcing rules, and less subject to social pressure or the need to negotiate with children.
Yet this support is tempered by realism. 63% of parents expect their children to react negatively to phone restrictions, highlighting that while these policy changes are generally welcomed, their day-to-day implementation is likely to be difficult.
Crucially, the findings suggest that schools are being looked to as allies rather than enforcers. There is growing acceptance that intervention is necessary, but less confidence that school rules alone can undo habits that have developed beyond the classroom.
New laws won’t have an impact if changes aren’t also made at home
Support for intervention does not translate into confidence that it will be effective on its own. A recurring theme in the data is the gap between what happens during the school day and what happens at home.
While 70% of people support schools restricting junk food, nearly half believe parents are unlikely to mirror these changes in the evening. This points more to the difficulty of maintaining change at home than any lack of support for healthier eating. 56% say healthy meals are too expensive, and 47% say their children are too fussy to eat them.
The same pattern appears in attitudes to technology. Concern about smartphone use is widespread, yet 55% believe parents are unlikely to limit screen time at home. As a result, 64% of the public think school-based changes will have limited impact unless they are reinforced outside the classroom.
This strengthens the sense that the challenge has shifted. Awareness is high, and support exists in principle, but many families feel constrained by cost, convenience, and resistance from children. The result leaves many families caught between what they believe is right, and what feels sustainable at home.
Why intervention now matters
For many people, the need for intervention feels urgent as it may be arriving too late for today’s teenagers. Almost 1 in 3 adults think teens were exposed to smartphones too early, and 57% believe their digital habits are now too ingrained to change.
By contrast, attitudes towards younger children are much more hopeful. 85% of people believe there is still time to help them build better habits if action is taken early, which reflects a broader belief that behaviours are easier to influence while habits are still forming. Interestingly, people are more optimistic about changing how teenagers eat than how they use technology: 64% believe it is still possible to improve a teenager’s relationship with food, even if their phone habits feel harder to shift.
This creates a clear public distinction between prevention and management. Younger children are seen as still reachable, while older teenagers are increasingly viewed as a group whose behaviours may need to be contained rather than reversed. The concern is not only that habits are unhealthy, but that some may already be too embedded in everyday teenage life, making delay feel riskier, early intervention more essential and the work of movements like ‘Smartphone Free Childhood’ increasingly significant.
This societal tension needs to translate into action, faster than it currently is
Public concern around screen time, diet, and behavioural health is translating into support for intervention, particularly for younger children, where change still feels possible and worthwhile.
As discussions continue around phone bans, school food standards, and wider safeguarding measures, the national mood appears to be shifting. The focus is less on whether to intervene, and more on who can lead practical change, and whether current approaches are overestimating how much impact school rules can have on behaviours shaped far beyond the school gate.
