Air fryers have rapidly become a kitchen essential across the UK, prized for their convenience, affordability, and ease of use. Yet, despite their popularity, these appliances carry a fire risk if used or maintained incorrectly.
Brian Michie, Managing Director at SBS Limited, a fire protection specialist company, warns that while air fryers themselves aren’t inherently hazardous, improper usage can lead to dangerous situations.
A key mistake is insufficient ventilation. Air fryers work by circulating hot air at high speed, meaning they require adequate space around them to operate safely. Positioning an air fryer too close to walls or cramped in corners restricts airflow and raises the chance of overheating.

“Many users underestimate how crucial it is to keep vents on the fryer’s back and sides unobstructed,” Brian explains. “Just a few inches of clearance can significantly improve safe operation.”
Another critical hazard is powering air fryers with extension cords or power strips. These appliances pull a substantial electrical load, which typical cords are not designed to handle safely. Overloading leads to generated heat, a common ignition source.
“It’s safest to plug the fryer directly into a wall outlet,” Brian advises, emphasizing that indirect power sources increase fire risk.
Vertical clearance is equally important. Using an air fryer under cabinets or shelves with limited space above can cause heat buildup and potential fire hazards. Brian cautions, “If there isn’t enough clearance overhead, the appliance shouldn’t be used in that position.”
Regular cleaning also plays a vital role in safety. Grease and food residue accumulate quickly, especially around the basket and heating element, increasing the likelihood of grease fires.
Brian recommends, “Clean the basket after every use and wipe down the heating elements frequently to prevent dangerous buildup.”
Avoid overfilling the fryer basket as well. When crowded, hot air circulation is impaired, forcing the fryer to work harder and generating more heat than it’s designed to handle.
“Cooking in batches keeps the fryer functioning safely and efficiently,” Brian notes.
Finally, never leave an air fryer unattended while in operation. Just as you wouldn’t leave a pan of hot oil on the stove alone, the same care should apply here.
“These appliances reach high temperatures quickly and can react suddenly to blockages or grease buildup,” Brian stresses. “Always stay close and turn it off if you need to step away.”
By following these essential tips—keeping the fryer well-ventilated, properly powered, cleaned, and monitored—owners can enjoy the convenience of air frying without compromising home safety.
