Why School Holidays Are Your Highest-Risk Period and What to Do About It

A school with 1,200 pupils and 80 staff is one of the most naturally surveilled environments in the UK. Then the holidays arrive, and all of that human presence disappears overnight. The gates close, the car parks empty, and what was a busy, well-watched site becomes a largely unmonitored building full of expensive equipment. Criminals know this. Holiday periods consistently see higher rates of break-ins, vandalism and fly-tipping at school sites than term time. The good news is that with the right preparation, the risk is very manageable.

Understanding the Risk

The threats schools face during closures are not random. They follow predictable patterns, which makes them preventable.

Theft of equipment is the most financially damaging. Laptops, tablets, projectors and AV equipment are high-value, portable and easily sold. A single well-planned break-in can strip thousands of pounds worth of kit from an IT suite in under an hour. Schools often leave this equipment on desks or in unlocked rooms, making it straightforward to grab.

Vandalism tends to be opportunistic. An empty school with no visible security presence signals to opportunists that they are unlikely to be disturbed. Graffiti, broken windows and damaged fencing are common results. Left unaddressed, visible damage attracts further incidents.

Trespassing brings its own problems. Unsupervised access to a school site creates liability risks and safeguarding concerns, and trespassers who damage themselves on school property can lead to insurance and legal complications.

Fly-tipping is a growing issue for schools with accessible car parks or service yards. Once a site is used once, it tends to be used again. Clean-up costs and potential environmental penalties are significant.

Cyber threats do not pause for the summer. Dormant networks with fewer people monitoring them are attractive targets. Ransomware and phishing attacks on school systems tend to go undetected for longer during holidays, giving attackers more time to cause damage.

The Pre-Holiday Security Check

The most important security work happens before the last member of staff leaves. This should be a formal, documented process, not a quick walk-round by one person at the end of a busy term.

Physical checks should cover the full perimeter: all fencing, gates and barriers. Look for weak spots, loose bolts, damaged sections and anything that could provide an easy entry point. Every external door and window needs to be checked and secured, including those in temporary buildings and outbuildings. Clear the grounds of loose items, debris and anything that could be used to climb or cause damage. Bins and skips should be moved away from buildings.

Technology checks should confirm that all CCTV cameras are operational, lenses are clean and the recording system has enough storage for the full holiday period. Test the intruder alarm and confirm that monitoring centre contact details and keyholder information are current. Check that all external security lighting is working, particularly motion-activated units.

Asset security means getting valuable equipment into locked, designated secure rooms rather than leaving it on desks. Smaller high-value items should be moved to a single secure location. Critically, back up all key data to an off-site or cloud location before you close. A ransomware attack during the holidays is far more damaging if your last backup is two months old.

What Technology Actually Does During Holidays

A CCTV system with remote access lets a business manager or site manager do a virtual walk-round from their phone without physically visiting the site. Modern cameras with motion detection can send push alerts to a mobile app if activity is detected in an area where there should be none. High-resolution cameras with good night performance are particularly valuable for the long, dark evenings of winter closures.

The critical upgrade for holiday periods is professional monitoring. A self-monitored system relies on someone in your team seeing an alert and responding. During the summer holidays, that person might be on holiday themselves, or asleep, or simply not looking at their phone. A professionally monitored system through an NSI or SSAIB-approved Alarm Receiving Centre means trained operators are watching 24 hours a day, seven days a week, regardless of what your staff are doing.

When a camera or alarm is triggered, the ARC operator reviews the footage in real time. They can distinguish between a genuine intruder and a fox crossing the car park, which matters for police response. If a Unique Reference Number (URN) is in place, confirmed activations can receive a police response. Keyholders are contacted in sequence. Every activation is logged and reportable.

Access control systems add another layer. The system can be configured to deny all access during the closure period, with specific exceptions for pre-authorised maintenance contractors or cleaning staff. Every entry attempt is logged with a timestamp. When school reopens, you have a complete audit trail of who was on site and when.

Intruder alarms should be monitored rather than simply audible. A siren that goes off at 2am in an empty street is not a security system. A monitored alarm that triggers a verified response is.

Procedures That Support the Technology

Technology does not operate in a vacuum. A few straightforward procedural steps significantly improve its effectiveness.

Let your local police community support officers know your holiday schedule and give them a keyholder contact number. PCSOs can include your site on their patrol routes during extended closures, and a visible police presence is a deterrent in itself.

Review your keyholder list before every closure. Contact details change, people leave, and a list that has not been updated is a list that will let you down when it matters. There should be at least two or three keyholders available at all times during a closure, not one person who is also the one most likely to be away.

Inform neighbours and local businesses that the school will be closed and ask them to report anything suspicious to 101. A community that knows to be vigilant is an extension of your security system.

When School Reopens

The return from holidays should include a formal site inspection before any pupils or non-essential staff arrive. A nominated person should walk the full site, inside and out, looking for signs of entry, damage or anything out of place. Check that all security systems were recording throughout the closure and review any alerts that were generated.

Any damage or suspected theft should be reported to the police immediately and your insurer notified. Clear CCTV footage from the closure period will be the most important asset in any insurance claim or police investigation. Ensure footage is preserved and not overwritten before it is reviewed.

If anything was compromised during the holidays, treat it as an opportunity to improve your pre-closure checklist for next time. Most holiday-period incidents are preventable with better preparation.
