Tower Hamlets Council prosecuted Sofina Begum, 52, and Aminur Rahman, 55, who owned the fourth-floor flat in Maddocks House, Shadwell where tenant Mizanur Rahman, 41, died in a fire on March 5, 2023.
The blaze was caused by a faulty lithium-ion e-bike battery which was charging at the time.
The property was licensed for just three people from two households.
The pair were sentenced at Snaresbrook Crown Court following their convictions in November 2023 before Thames Magistrates’ Court.
The council successfully obtained a confiscation order, which is a court order to recover money made from illegal activities.
Sofina Begum was ordered to pay a fine of £10,000 and £2,000 in prosecution costs, as well as a victim surcharge of £2,000.
She was also told to pay a confiscation order of £78,049.
Aminur Rahman was ordered to pay a fine of £2,000 and the victim surcharge of £800, as well as a confiscation order of £1.01.
The landlords had previously pleaded guilty to a total of nine charges brought under the Housing Act 2004.
This included allowing the premises to become overcrowded, failing to comply with licensing conditions, not conducting required inspections, lacking a valid gas safety certificate, and failing to provide the council with requested documentation.

“Our thoughts and prayers remain with the family and friends of Mizanur Rahman, who tragically lost his life in the fire, caused by a faulty e-bike battery, at Maddocks House, and with all those affected by this devastating incident.
“We are clamping down on rogue landlords who operate in our borough.
“We pursued this prosecution and the court’s decision sends a clear message: we will not tolerate criminal landlords who endanger lives for profit.”
