Staying Safe in the Heat: How to Prevent Fires During Hot Weather in the UK
As temperatures across the UK continue to rise, so does the risk of fires — both in our homes and in the wider environment. Prolonged hot and dry spells create conditions where fires can start more easily and spread far more quickly than usual. Whether you're at home, in the garden, or out and about, here's what you need to know to stay safe this summer.
Why Heat Increases Fire Risk
High temperatures dry out vegetation, materials, and surfaces that would normally contain some moisture. This makes them far more flammable. Combined with strong winds and low humidity, a small spark can quickly become a serious blaze. The UK has seen a significant increase in grass fires, wildfires, and home fires during recent heatwaves — and fire services across the country urge extra caution during these periods.
At Home
In the Kitchen
- Never leave cooking unattended, especially on the hob — heat makes oils and fats reach ignition point faster than usual
- Keep kitchen windows open where possible to reduce heat buildup
- Avoid using the oven during the hottest parts of the day if you can
Electrical Appliances
- Don't overload plug sockets — appliances generate more heat in already warm conditions
- Unplug appliances that aren't in use, especially overnight
- Make sure tumble dryers and washing machines have proper ventilation — these are a leading cause of house fires year-round, and heat makes them more dangerous
- Never charge phones, laptops, or e-bikes/e-scooters unattended or overnight
General Home Safety
- Test your smoke alarms — this is a good habit at any time of year but especially important now
- Keep flammable materials like curtains, paper, and fabrics away from windows where sunlight can concentrate heat
- Be careful with candles — never leave them burning unattended and keep them away from direct sunlight
In the Garden
- Avoid bonfires and burning garden waste during hot, dry, or windy conditions — fire can spread to fences, sheds, and neighbouring properties incredibly quickly
- BBQs need extra care — only use them on a stable, non-flammable surface, never leave them unattended, and make sure they are fully extinguished afterwards. Never use a BBQ indoors or in a garage
- Keep garden furniture and trampolines away from the house where possible — they can act as fuel if a fire starts nearby
- Store petrol, gas canisters, and lighter fluid safely away from heat sources and direct sunlight
In Open Spaces
- Never have a BBQ or open fire on grassland, in woods, or in parks during dry weather
- Don't discard cigarettes from car windows or drop them on dry ground — this is one of the most common causes of grass fires
- Broken glass and bottles left in sunny spots can act as a magnifying glass and start fires — dispose of them responsibly
- If you see a wildfire or grass fire, call 999 immediately — do not attempt to tackle it yourself
In Your Car
- Aerosols, lighters, and hand sanitiser left in a hot car can become a fire hazard — remove them or store them safely
- Check your tyres — underinflated tyres can overheat on hot road surfaces
What to Do If a Fire Starts
- Get everyone out immediately — don't stop to collect belongings
- Close doors behind you to slow the spread of fire
- Call 999 as soon as you are safely outside
- Never go back into a burning building
- If smoke is present, stay low where the air is cleaner
A Final Word
A little extra caution during hot weather goes a long way. Fires can start in seconds but the consequences can last a lifetime. Make sure your smoke alarms are working, talk to your family about what to do in an emergency, and be mindful of the extra risks that come with high temperatures.
