Demolition News editor, Mr Anthony, said “Here we are five years on no closer to understanding what caused it – there have been no prosecutions, no preliminary reports. There are still four families out there that have got no closure – no clue as to why their loves ones did not return home that day. The industry itself has no clue as to what it might do differently to avoid a repeat.”

Police investigating the collapse previously said they had examined almost 900 tonnes of evidence. Dep Ch Con Jason Hogg said: “As from day one we continue to investigate with the same focus, dedication, and a commitment to find out what led to the deaths of the four men and obtain answers for their families.

The power station dominated the surrounding landscape and was first used to generate power in 1970. In 2013, after 43 years of service, Didcot A Power Station was turned off, the power station’s six cooling towers were demolished by professional demolition contractors in two stages.

The final part of Didcot coal-fired power station was demolished nearly seven years after it was closed for good, the chimney demolition was nearly 200 meters high and one of the tallest structures in the country when it was brought down.

The power station has had its fair share of controversy over the years, in November 2006 Greenpeace protesters climbed to the top of one chimney and stayed there for two days, while 20 people were arrested in another protest back in October 2009. The power station was also voted as Britain’s third worst eyesore in 2003.

The demolition company involved in the investigation has previously stated that it does not believe it is responsible for the incident, in previous company accounts released the firm wrote:

“Investigations by external authorities are still under way but, as previously noted, the directors do not believe the company is responsible for the cause of the incident. This is based on rigorous independent inquiries and on advice received from the company’s professional advisers.”
