Refracted sunlight is believed to be the cause of a balcony blaze on Hayling Close in Hackney this evening.
The first floor balcony of the town house was gutted by fire.
Two adults and five children left the property before the Brigade arrived. One adult and one child were suffering from smoke inhalation and treated at the scene by London Ambulance Service crews.
The Brigade's top three safety tips
• Keep mirrors and crystal or glass objects away from the sunny sills
• Fit at least one smoke alarm per floor and test them every week to make sure they work and the batteries are not flat
• If you have a fire, close the door on the blaze, get out stay out and call the Brigade
The Brigade was called at 1845 and the fire was under control by 1931. Fire crews from Stoke Newington, Islington and Ilford fire stations were at the scene.
