Ten fire engines and around 70 firefighters were called to a fire near Mount Pleasant Lane in Clapton.
The fire involved a four-storey block of maisonettes. One maisonette on the ground and first floors of the building was destroyed by fire. A further five flats sustained partial damage. The external fascia and balcony of a flat on the second and third floors was also damaged.
One person was treated at the scene by emergency service crews but did not require any hospital treatment. There were no reports of any further injuries.
The fire was producing a significant amount of smoke. The Brigade advised people in the local area to keep their windows and doors closed due to smoke travel. A number of road closures have also been in place.
Deputy Assistant Commissioner Chris Jenner, who is the Commander for the North East Area, said: “Crews were met with a well-developed fire, which was spreading. The conditions inside the maisonette that was mostly alight were challenging and firefighters worked professionally and safely to bring this part of the fire under control as swiftly as possible. Firefighters worked exceptionally hard and quickly to prevent the fire spreading and causing significant damage to other flats in the building.
“After arriving on scene, crews carried out a full search of the building. Several residents had already safely evacuated the building, with one person led to safety by firefighters.
“Working alongside the local authority and other agency partners, a rest centre was set up locally for around 20 displaced residents, who were supported by officers and our Community Engagement team. Some of those residents were able to return home overnight with those unable to return home left in the care of the local authority. Over the coming days, we will continue to engage with the local community and carry out home fire safety visits in the area.
“Firefighters have worked through the night to extinguish hotspots and a small number of crews remain on scene today.
“An investigation into the cause of the fire is ongoing by our Fire Investigation Team and the Metropolitan Police; however at this stage, we do not believe the fire was started deliberately.”
The Brigade received the first of 67 calls about this fire at 2004 and Control Officers mobilised crews from Stoke Newington, Tottenham, Homerton and surrounding fire stations to the scene. A 32-metre turntable ladder was also in attendance.
The fire was brought under control by 2254.
The cause of the fire is under investigation.
