A group of property owners have promised to launch a class action against NSW company Endeavour Energy, in response to damaging fires which swept through the Blue Mountains last year.

The owners blame a fallen power pole for blazes which left 700 people homeless.

They allege the energy distributor failed to provide adequate maintenance in fire-zone areas and want courts to investigate.

Local resident Julie Willis has told 7.30 NSW she wants the energy company to be held accountable.

"Maybe they should take more responsibility where they put their lines and what's around their lines even if it is on other people's property."

Endeavour Energy has responded saying that they are fully committed to public safety.

"We understand the NSW RFS preliminary investigations indicate that the Linksview Rd, Springwood fire was started by a large tree falling across power lines during high winds. "The cause of this fire is also being investigated by the NSW Coroner and we’re doing everything we can to assist with this."

Residents have also been highly critical of the State Government’s unwillingness to provide tax relief for those forced to purchase new properties and pay large amounts of stamp duty.

Julie McGuinness, who is rebuilding her Blue Mountains home has been forced to rely on handouts and says more could be done by authorities.

"Friends that are struggling themselves with their daily lives have given us their hard-earned money to help us get into our home," she said.

"If government can give us some relief from stamp duty - even just deferring it, so we don't have to pay lump sum straight away - we could pay it back over five years and rebuild our lives."

The State Government has been approached to comment.
