The Electrical Contractors' Association (ECA) has warned companies that fail to undertake regular electrical maintenance risk retribution under proposed corporate manslaughter laws.
The ECA has come out in support of the government's plans to introduce a corporate manslaughter charge.
The new charge will make individuals
with management responsibility criminally liable for serious accidents involving their employees or members of the public.
ECA figures show electrical fires in the workplace killed 95 and injured 3,325 people between 1990 and 1995.
The fires also caused more than £320m worth of damage.
An ECA spokesman said: "The proposed legislation could have far-reaching consequences for those companies and individuals within companies where electricity-related accidents occur."
"It's essential that companies undertake regular planned electrical maintenance in order to ensure safety."
