Four fire engines and around 25 firefighters tackled a fire at a church building on South Mall in Edmonton.
Part of a church building on the first floor of a mixed-use block was damaged by fire. There were no reports of any injuries.
The fire was discovered when fire alarms sounded and security staff found smoke coming from the top of the church entrance door.
The fire is believed to have been accidental and caused by an unattended candle.
A London Fire Brigade spokesperson said: “It’s really important that you never leave candles unattended and keep them away from anything that could catch fire such as curtains, furniture or clothes.
"We recommend swapping traditional candles for LED flameless ones as they are much safer, but if you do use real candles, follow our simple safety tips."
The Brigade was called at 1835 and the fire was under control by 1945. Fire crews from Enfield, Chingford, Southgate and Walthamstow fire stations attended the scene.
