When the UK heats up, most people think about barbecues, fans, paddling pools and trying to sleep at night. But extreme temperatures also bring a much higher risk of fire,  both at home and in commercial properties.

At Bath West Fire & Security, we’ve already seen an increase in seasonal fire safety concerns during hot weather periods. From overloaded extension leads to dry garden fires and overheating electrical systems, heatwaves can create serious fire hazards if you’re not prepared.

Here’s some practical fire safety advice to help protect your home, business and family this summer.

Why Heatwaves Increase Fire Risk

Extreme heat creates the perfect conditions for fires to start and spread quickly. Dry grass, overheated electrical equipment and increased use of cooling appliances can all contribute to fire incidents.

During hot weather, common causes of fire include:

• Overloaded electrical sockets
• Faulty fans or portable air conditioning units
• BBQ and outdoor cooking accidents
• Disposable BBQs on dry grass
  
• Cigarettes discarded outdoors
• Lithium-ion battery overheating
• Increased strain on commercial electrical systems
• This is why fire prevention becomes even more important during periods of extreme heat.

 

Home Fire Safety Tips During Hot Weather

Avoid Overloading Plug Sockets

Fans, portable air conditioners and extra appliances often mean more extension leads and overloaded sockets during summer.

To reduce electrical fire risk:

• Never plug multiple high-powered devices into one extension lead
• Check cables for heat damage
• Unplug appliances when not in use
• Avoid running fans overnight unattended
• Electrical fires remain one of the leading causes of house fires in the UK.

 

Be Careful With BBQs and Outdoor Cooking

Nothing says British summer like a BBQ — but they’re a major cause of accidental fires every year.

BBQ Safety Advice

• Keep BBQs well away from fences, sheds and dry grass
• Never leave cooking unattended
• Keep children and pets away
• Avoid disposable BBQs in parks or dry areas
• Fully extinguish coals after use

 

Even a small spark can quickly spread during a heatwave.

Check Your Smoke Alarms

Hot weather is the perfect reminder to test your smoke alarms and fire alarm systems.

You should:

• Test alarms weekly
• Replace batteries if needed
• Ensure smoke detectors are installed on every level
• Upgrade outdated systems where necessary

 

Working smoke alarms save lives and provide critical early warning in the event of a fire.

 

Fire Safety for Businesses During a Heatwave

Commercial buildings face additional risks during extreme temperatures, especially where electrical systems are under pressure.

Business Fire Safety Checklist

• Inspect server rooms and electrical equipment
• Ensure fire extinguishers are accessible
• Check emergency lighting systems
• Test fire alarm systems
• Review fire evacuation procedures
• Avoid blocking ventilation systems
• If your business relies on air conditioning or cooling equipment, regular maintenance is essential to prevent overheating and electrical faults.

 

Lithium Battery Fire Risks in Summer

E-bikes, power tools, laptops and vape devices all use lithium-ion batteries, which become more dangerous in high temperatures.

Battery Safety Tips

• Never charge batteries in direct sunlight
• Avoid charging overnight
• Use manufacturer-approved chargers
• Stop using damaged batteries immediately
• Store batteries in cool, dry areas
• Battery fires can spread rapidly and are extremely difficult to extinguish once ignited.

 

Don’t Ignore Fire Alarm Maintenance

Summer is often when businesses become quieter due to holidays — making it an ideal time for fire alarm servicing and fire risk assessments.

Routine maintenance helps ensure:

• Your fire alarm system works correctly
• Emergency exits remain compliant
• Fire extinguishers are operational
• Your property meets UK fire safety regulations
• Regular servicing can also reduce false alarms and identify potential issues before they become dangerous.
