On 10 December 2014, Mr Edge, fell from the roof of a metal structure he was helping to dismantle in Ramsbottom, Bury.
He died hours later at Salford Royal Hospital, after suffering catastrophic head injuries.
At the time of the fall, Mr Edge was working for SR and RJ Brown and was working on a site run by Marshalls Mono.
A joint investigation by the Greater Manchester Police alongside the Health and Safety Executive (HSE) looked into the circumstances surrounding Mr Edge’s death.
It was heard in court how MA Excavations Ltd, contracted out the work to brothers Christopher and Robert ‘James’ Brown, directors at SR and RJ Brown Limited.
Mark Aspin, director at MA Excavations Ltd said he believed the Browns were ‘competent’ and could complete the job safely, but the court heard he did not check their qualifications.
Manchester Evening News reported that Robert ‘James’ Brown composed a ‘grossly inadequate’ risk assessment before the job which he did not show to anyone.
After Mr Edge was rushed to hospital he then typed up another risk assessment, which should have been done beforehand.
Peter Heap, 34, who had been working alongside Mr Edge was asked by Christopher Brown, 25, to go home and collect harnesses to make it look like the accident was Mr Edge’s fault, because he had not worn safety equipment.
“Foolishly, weakly and criminally – as he now realises – Peter Heap went along with what he was told to do,” Mr Justice Openshaw said.
The Browns maintained that the harnesses had been there before the incident, although they did admit falsifying the risk assessment.
During sentencing, addressing Christopher Brown and Robert ‘James’ Brown Ben’s mother said that when she saw her son’s coffin at the funeral she wanted to drag those responsible to the coffin so they could see what they had done.
She said: “Ben’s death was totally avoidable. He had everything to live for, but his future was stolen from him.”
Mrs Edge added: “Benjamin Edge, known affectionately as Ben, was my son and his father, Tim’s, son. We are so proud of Ben, not just what he achieved, but who he was.”
Ben’s family have issued a tribute to their son, who leaves behind a three year-old daughter, a loving mother and father, twin brother, and partner.
“Ben was taken from us in tragic circumstances aged only 25, and our family and all of his friends are totally grief stricken by his loss.
“We miss him so very, very much.
“He was a loving, caring son, twin brother and family man. Ben was a much loved partner and father and will always remain a huge part of everyone’s lives”.
