Cool UK's Overheating Schools: Tips for Parents and Teachers 2026

Cool UK's overheating schools is a pressing concern this summer as repeated heatwaves drive classroom temperatures to unbearable levels. Parents, teachers, and governors are scrambling to find affordable solutions while awaiting long-term government action. Here are practical steps you can take now to keep pupils safe and comfortable.

Why UK Schools Are Overheating

Many UK school buildings were designed for a cooler climate, with large windows and poor insulation. As climate change intensifies, temperatures inside classrooms regularly exceed 30°C, leading to closures and health risks. Experts agree that extreme heat is becoming a public health and safeguarding issue, not just a facilities problem.

First Steps for Parents

The first step is to raise the issue constructively with the school. Form a small group linked to the parent-teacher association to demonstrate a collective concern. Approach headteachers collaboratively—they face huge financial pressures. Next, ask the school to contact their local authority, foundation, or academy trust; many now have sustainability or climate resilience teams that can offer free advice.

Understanding Your School Building

Before spending money, understand why the building overheats. Polly Turton of Shade the UK warns: “There is a real risk that schools rush into installing air conditioning or invest in shading that isn’t appropriate.” A professional heat audit can identify the best interventions—whether it’s reflective paint, external shading, or improved ventilation.

Low-Cost Interventions to Cool Classrooms

Here are some immediate, low-cost measures parents and teachers can implement:

• White paint or reflective coatings on roofs and walls to reduce solar heat gain
• External blinds or shade sails over south-facing windows
• Tree planting to provide natural shade and cool the air around the building
• Portable fans and strategic use of night-time ventilation
• Adjusting school timetables to avoid peak heat hours for outdoor activities

Comparison of Cooling Options

As the table shows, air conditioning is not always the best answer—it’s expensive, energy-intensive, and can be inappropriate for listed buildings. Natural solutions like shading and tree planting offer sustainable long-term benefits.

Key Takeaways for Cooling Schools

• Collaborate with the school—don’t assume nothing is being done
• Request a professional heat audit before investing in solutions
• Prioritise low-cost, passive cooling measures like paint and shading
• Engage with local authority climate resilience teams
• Plan for both immediate relief and long-term adaptation
