Investigators have been unable to find out what caused the blaze at The White Horse pub.
About 40 firefighters fought the flames at the disused watering hole in the High Road, Chadwell Heath on Sunday, September 20.
Most of the historic, locally listed building was destroyed in the fire. There were no reported injuries.
London Fire Brigade (LFB) has confirmed that its investigators have been unable to determine the cause of the blaze because of the severe damage caused.
A bus driver on the road at the time radioed TfL to report that the two-storey building was on fire. TfL then alerted the fire brigade at 4.47am. The fire was under control by 7.17am.

Firefighters saw large amounts of smoke on the road as they arrived. Crews from Dagenham, Ilford, Romford, Hainault, Barking and East Ham fought for several hours to extinguish the flames, which spread from a corner of the roof to the rest of the building. Firefighters also used drones to help.
