Firefighters have issued a safety warning after sunlight reflecting off a mirror is believed to have caused a fire at a house in Lady Margaret Road, Southall.
Two fire engines and 10 firefighters and officers were called to the blaze.
Part of a bedroom on the ground floor of the semi-detached house was damaged in the fire.
One man was out of the property before the Brigade arrived and was taken to hospital suffering smoke inhalation.
A spokesperson for the London Fire Brigade said: “These sort of fires are not as rare as you would think and shows these types of fires are not an urban myth.
“Crystals, glass ornaments and items such as dressing table mirrors should be kept out of direct sunlight.
“Everyone should have at least one smoke alarm on every level of their home and the safest option is to have those linked together.
"This will give the earliest warning if there is a fire in your home."
The Brigade was called at 1335 and the fire was under control at 1420. Fire crews from Southall fire station attended.
