Exact temperature it has to be for schools in England to close this winter

Why there isn’t a single temperature that triggers school closures

If you look at the headlines, you might expect a precise degree—say 15°C or 18°C—as the moment a school must shut. Reality is a lot messier. Temperature is important, but it’s not the only factor. Consider the four Cs: Comfort, Capacity, Connectivity, and Circulation.

First, comfort matters. Teachers and pupils deserve a classroom that’s safe to learn in. The commonly cited guideline is that indoor spaces should feel reasonably warm—often around 18°C as a minimum in many schools—so that learning can proceed without people shivering or losing focus. But comfort is subjective. A room that sits at 18°C with drafty windows feels different from a well-insulated space at the same reading. So, temperature is a guide, not a guarantee.

Second, capacity and occupancy change how temperatures feel. A full class will generate more heat than a nearly empty room, and a building with many occupied spaces can be harder to heat evenly. If some areas stay chilly while others are warm, it’s harder to run a normal day safely.

Third, connectivity—the ability to communicate with families and staff quickly—is crucial. If roads are dangerous or transport is unreliable, even a perfectly heated building can be rendered unusable because students can’t get there safely. Conversely, if transport is running but the school is risk-averse because of weather forecasts, closures may still be necessary.

Fourth, circulation and safety. A school building needs to be structurally sound and safe to enter. If a boiler fails, a heating system struggles, or there’s a risk of pipes freezing or power outages, administrators will weigh those risks before deciding to open or close. In short, you don’t close because it’s a touch cold; you close because the overall risk to students’ safety cannot be managed.

So, while a temperature is part of the conversation, it’s not the deciding factor. Think of weather- and safety-based closures as a carefully balanced checklist rather than a thermostat with a hard stop.

What temperature means for classroom comfort and learning

Establishing a practical target

Most schools aim for comfortable learning spaces without wasting energy. A common benchmark is to keep classrooms around 18°C or warmer, especially during lessons that involve young children who may feel cold more quickly. Some education authorities suggest higher targets during the winter months when students are more sensitive to cold, while others allow flexibility, understanding that energy costs and building design influence what’s feasible.

Of course, the actual temperature in a classroom is influenced by sunlight, building age, insulation, and how well the heating system is balanced. An older school with draughty windows may require longer heating times to reach a comfortable temperature, while a newer building with modern insulation can warm up faster and maintain warmth more efficiently. It’s not just about turning the heat up; it’s about turning the heat on early enough and keeping it even throughout the day.

Beyond numbers, comfort also means humidity, air quality, and draft control. A room that’s warm but stuffy can be uncomfortable just as much as a chilly room. Where possible, schools should balance warmth with air exchange to keep learning spaces healthy and conducive to concentration.

Energy efficiency and long-term costs

Winter warmth costs money, and budgets matter for schools. A well-maintained heating system can deliver reliable warmth without breaking the bank. Conversely, inefficiencies—like a radiator that’s not balancing properly, air leaks, or sludge buildup in the heating circuit—can waste energy and create cold zones that undermine comfort.

Addressing these inefficiencies isn’t only about comfort; it’s about safeguarding the school’s ability to stay open during tougher weather. When heating runs efficiently, it’s easier to maintain safe, warm learning spaces, which reduces the temptation to close on days when cold is the main challenge but safety isn’t.

For schools that want to optimize heating efficiency, professional services dedicated to school-quality heating can help. If you’re curious about improving boiler performance or ensuring a balanced system, consider consulting experts who specialize in educational facilities.

How winter decisions are made: a practical process for closures

Closing a school is never taken lightly. It’s a decision that involves several voices and a careful look at multiple data sources. Here’s a realistic view of the typical process during winter:

Step 1: Listen to the weather and travel advisories

Forecasts from reputable meteorological services inform the anticipated weather, including snowfall intensity, freezing rain, and wind chill. Local authorities and autumn/winter maintenance teams monitor road conditions and public transport viability. If predicted conditions look dangerous, planners begin contingency discussions well in advance.

Step 2: Assess transport and access

If bus routes, train services, or major roads are affected, families may struggle to get children to school safely. The safety of walkers, cyclists, and drivers is a priority. Transport teams and local authorities weigh the likelihood of disruption for the day and communicate early warnings when closures are probable.

Step 3: Check heating and building readiness

School facilities teams verify that boilers are functioning, fuel supply chains are stable, and that the building envelope isn’t compromising safety. If a boiler fails or there’s a risk to essential services, staying open becomes imprudent. In some cases, temporary closures may be necessary to protect students and staff while repairs are underway.

Step 4: Decide and communicate

If a decision is made to close, the school will notify families and staff as quickly as possible. Modern communications channels—texts, emails, school apps, and social media—help ensure messages reach households promptly. Transparent timing helps families plan for the day and arrange childcare if needed.

Throughout this process, temperatures and building comfort play a supporting role, but they’re rarely the sole determinant. A school might be prepared to open, with warm classrooms, yet decide to close due to transport hazards or a power outage. The goal remains safety first, followed by an environment conducive to learning when possible.

Practical steps schools can take to stay open safely in winter

While some days will inevitably require closures, there are proactive measures schools can adopt to maximize safety and warmth, reducing the frequency and duration of winter closures:

1) Build a robust heating plan

Develop a structured heating schedule that anticipates cold spells. Start heating early in the morning, pre-warm corridors and classrooms, and maintain a consistent temperature throughout the day. Regular maintenance ensures boilers operate reliably, reducing the risk of sudden outages. If you’re unsure where to start, a heating professional can tailor a plan to your school’s layout and occupancy patterns.

2) Improve insulation and draft exclusion

Drafts rob warmth and drive up energy usage. Weatherstripping doors, sealing gaps around windows, and using heavy curtains or blinds can help hold warmth inside classrooms. When windows must be opened for ventilation, consider smart scheduling so openings don’t coincide with peak cold periods.

3) Balance radiators and check for sludge

Radiators should heat evenly, with hot water circulating to all parts of the building. Air vents should be purged, and radiators bled where necessary. If you feel cold spots persist in many rooms, sludge buildup in the heating system can impede flow. This is where a professional service—such as a power flushing—can make a noticeable difference by removing sludge and improving circulation.

For schools facing radiator inefficiency, the results can be dramatic. Cleaner water flow means faster warm-up times and more stable temperatures across classrooms, which supports a safer environment for learning.

4) Prepare communication and contingency plans

Clear, timely communication with families matters as much as technical readiness. A well-defined plan includes how the school will notify changes, what remote learning options are available, and how meal services or transportation adjustments will be managed if closures occur.

5) Explore professional maintenance partnerships

Establish relationships with reputable heating technicians who understand school environments. Regular check-ins, predictive maintenance, and on-call support can prevent small issues from spiraling into closures. If you’re exploring service options, consider contacting established providers who specialize in educational facilities.

What parents should know and how to plan if closures happen

Parents and carers are on the front lines when schools announce closures. Quick, reliable information helps families rearrange plans with less stress. Here are practical tips for families facing winter disruptions:

1) Stay informed through official channels

Most schools publish closure information via text alerts, email newsletters, the school website, and social media. If you’re not already subscribed to your school’s communications, opt in ahead of the coldest months so you’re not scrambling when a decision is made in the early morning.

2) Have a flexible plan for childcare and work

Winter days can be unpredictable. Discuss contingency arrangements with employers and consider informal backup arrangements with friends or family that know your child’s needs in case of last-minute closures.

3) Use remote learning when available

Many schools offer remote learning options or activity packs when closures are unavoidable. Having a plan for keeping students engaged—whether through online lessons, recorded content, or independent study packets—minimizes learning disruption and reduces stress for families balancing multiple responsibilities.

4) Prepare for cold classrooms if closure is unlikely but temperature is borderline

If a day seems borderline—where travel is possible but chilly classrooms remain—the family can ensure appropriate clothing and warm layers for kids, as well as planning breaks to allow students to warm up if needed. Schools can also share tips on how to help students arrive warm and ready to learn, even when outside temperatures are low.

Heating systems in schools: keeping warmth up and costs down

Heating systems in schools are under constant pressure during winter. A reliable system isn’t just about cranking up the heat; it’s about efficient, consistent warmth that supports focus and well-being. Here’s how to approach this topic practically:

Regular maintenance matters

Boilers, pumps, thermostats, and control systems require routine checks. Scheduling annual servicing helps catch small issues before they escalate into failures during the coldest weeks. A well-maintained system reduces the risk of sudden outages that could force an early closure.

Efficiency upgrades pay off

Upgrades like modern thermostats, zone heating, and improved insulation pay for themselves over time by lowering energy use and improving comfort. If your school is weighing upgrades, a professional assessment can help you identify the most impactful improvements within budget constraints.

When facing stubborn inefficiencies, professional services can be a game changer. For example, a Powerflush can restore radiator efficiency by removing sludge and debris that hinder hot water flow. It’s one of the practical steps that can improve comfort without large energy hikes.
