Faulty fuse boxes are causing five house fires a week in the capital, according to new figures by the London Fire Brigade.
They say defective wiring and components are behind the problem. New regulations are being announced which will require them to be flame proof from 2015.
There's been a five fold increase in fires started by fuse boards over five years.
It's believed the increase is because many homes have installations subject to product recall.
Also, sometimes the wiring is not fitted properly at the time the unit is installed.

London Fire Brigade Station Manager Rhodri Horton, who is at the scene said:
“When crews arrived they were faced with a rapidly developing fire affecting the whole of a three storey house under refurbishment. Firefighters are working hard to bring the fire under control.
"A mother and a daughter from a neighbouring property escaped into their garden. Fire crews used a ladder to get them over a fence and away to safety. Thankfully they were both uninjured.”
