Four fire engines and around 25 firefighters tackled a house fire on Grove Crescent in Feltham.
Half of the ground floor of a terraced house was damaged by fire. A man was treated on scene by London Ambulance Service crews and a woman was taken to hospital.
The Brigade’s Control Officers took the first of three calls to the fire at 1747 and sent crews from Twickenham and Feltham fire stations to the scene. The fire was under control by 1854.
The cause of the fire is under investigation by the Brigade and the Metropolitan Police Service.
