Too hot to handle? Protect your tech in a heatwave

July 7th 2026

When hot weather hits, social care providers rightly focus on keeping people safe, cool and hydrated. But heat can also affect the technology your service relies on every day — from care planning systems and electronic medication records to phones, laptops, routers, sensors, alarms and other tech enabled care.

Recent NHS reports show how quickly heat can disrupt essential services. During the June heatwave, hospitals declared critical incidents after cooling failures affected IT systems, MRI scanners and other clinical equipment. Queen Alexandra Hospital in Portsmouth reported that loss of cooling capacity had affected digital systems and critical clinical services. Norfolk and Norwich University Hospitals NHS Foundation Trust also reported problems with MRI scanners after cooling systems were affected by heat and humidity.

The issues may be different in social care, but the message is the same: extreme heat can increase the risk of disruption, data loss, device failure and cyber incidents. If systems slow down or stop working, staff may be more likely to use workarounds, delay recording, miss alerts or use personal devices. That can create risks for people drawing on care, staff and the organisation.

Start with the kit you rely on most

Think about which technology would cause the biggest problem if it failed. This might include internet connections, Wi-Fi, phone systems, digital care records, medication systems, access control, nurse call systems, falls sensors or monitoring equipment.

Check server cupboards, comms rooms and areas with routers, switches or phone equipment. Keep them clear of boxes and paperwork, which can block airflow and trap heat. If you use air conditioning or fans in these spaces, check they are working safely. If you spot old-looking equipment, ask your IT or telecoms provider before switching it off — it may still be doing an important job.

Look after mobile devices on the move

Home care staff often carry phones or tablets between visits. These can overheat quickly if left on a dashboard, passenger seat, windowsill or in direct sun. Encourage staff to keep devices in the shade, carry them in a bag rather than loose in a hot vehicle, and avoid charging them in direct sunlight.

If a device shows a temperature warning, shuts down or feels unusually hot, staff should stop using it, move it out of the heat and report the issue. Don’t put devices in fridges or freezers — sudden temperature changes and condensation can cause damage.

Reduce cyber risk during disruption

Heat does not cause a cyber attack by itself, but disruption can lead to risky workarounds. When systems are down and staff are under pressure, people may be tempted to share passwords, use unapproved apps, save information locally or send personal data to personal email accounts so they can keep working.

Remind staff that data protection and cyber security rules still apply during heatwaves. Make sure everyone knows the approved fallback arrangements, how to report IT problems, and what to do if a device is lost, damaged or behaving strangely.

Plan for continuity, not just cooling

Review your heatwave plan alongside your business continuity, cyber security and digital contingency plans. What would you do if Wi-Fi failed, your care planning system was unavailable, mobile devices overheated, or a power cut affected charging and connectivity? Decide who contacts suppliers, how staff record essential information, how updates are shared, and how records are brought back up to date safely.

Providers should also sign up for Heat-Health Alerts and use the UK Health Security Agency action cards for health and social care providers. They focus on protecting people’s health, but they are also a useful nudge to check whether the systems supporting safe care are ready for extreme weather.

Quick actions to take now

Keep key equipment cool, clear and well ventilated.
Keep phones, tablets and laptops out of direct sun.
Ask staff to report overheating or slow systems early.
Check backups and key supplier contacts.
Don’t use personal accounts, unapproved apps or shared passwords.
Agree how essential records and alerts will be managed if systems go down.

Heatwave planning is about people first. But in modern social care, protecting people also means protecting the technology, information and communication systems that staff depend on to provide safe, timely support.
