A toaster that was accidentally switched on is believed to have caused a flat fire on Thames Street in Greenwich.
Clutter left near a toaster accidentally pushed its leaver down and caused the plastic casing to ignite.
Part of a first floor flat was damaged by fire. Around 12 people self evacuated the block before the Brigade arrived.
London Fire Brigade spokesperson said:
"Keep clutter to a minimum on your kitchen work surfaces especially near toasters and hobs as they can accidentally switch them on or catch fire."
The Brigade was called at 1219 and the fire was under control by 1326. Four fire engines and around 25 firefighters from Greenwich, Deptford, and East Greenwich fire stations were at the scene.
