James Harper, the sole director of Cavendish Basements Limited, has received a suspended prison sentence after a worker was crushed by a collapsing excavation wall on a London site. The 50-year-old man suffered life-changing injuries during the incident on Vant Road. Harper failed to report the accident to the Health and Safety Executive, prompting a delayed investigation that uncovered multiple systemic safety failings across the project.
Background
The injured man was working within an unsupported trench when the side of the excavation fell towards him. The collapse left the worker pinned against the wall and critically injured. Harper did not notify the regulator of the incident, directly breaching the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2012. The injured worker's solicitor eventually reported the accident to the Health and Safety Executive two months later, triggering an immediate site inspection.
Industry implications
Inspectors visited the Vant Road site multiple times following the delayed report. They found that the construction work was not planned, managed, or monitored to ensure safety. The regulator identified specific, ongoing failures regarding the stability of structures, excavation support, work at height, and general site supervision. These discoveries resulted in multiple enforcement notices being issued to the company. The case highlights the severe legal and financial risks for company directors who attempt to conceal site accidents from the authorities.
What contractors should do now
Contractors must ensure all excavation work is properly supported, battered back, or shielded before any worker enters the trench. Site managers must report qualifying injuries to the regulator under the statutory timeframes set out in the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations. Directors must actively monitor site conditions and verify that temporary works designs are implemented correctly, rather than relying on informal oversight.
Expert view
This prosecution underscores the regulator's willingness to target individual directors when site safety management completely breaks down. The failure to report the incident compounded the severity of the enforcement action. By prosecuting under Section 37 of the Health and Safety at Work Act, the regulator has demonstrated that corporate structures will not shield individuals who neglect their duties under the Construction (Design and Management) Regulations 2015.
What happens next
Harper pleaded guilty to breaching Section 37(1) of the Health and Safety at Work Act 1974 by virtue of regulation 15(2) of the Construction (Design and Management) Regulations 2015. A judge sentenced him to six months in prison, suspended for two years. The court also ordered Harper to pay £4,608 in costs and a £154 victim surcharge. The Health and Safety Executive has confirmed that Cavendish Basements Limited remains under regulatory scrutiny.
