New figures from the Home Office show that 1,293 house fires were started by a household appliance in the area between April 2012 and March last year.
More than half the incidents attended by the West Sussex Fire and Rescue Service were started by cookers, with 767 fires causing 147 deaths or casualties over the five-year period.
Between April 2012 and March 2017, 247 fires started by domestic appliances caused deaths or injuries.
Over 110 fires were started by faulty appliances or leads in West Sussex over the five years. Across England, such faults started over 13,000 fires.
The most common reason for fires started by appliances was misuse of the equipment, which caused 863 fires in West Sussex, and nearly 48,000 nationally.
But the old staple of fire safety talks, chip pans, were still the cause of 132 fires in West Sussex, and over 9,000 fires nationally.
