Developer Fined £20,000 After Labourer Drowns in Water-Filled Excavation

Background

Alchemist DB Limited, acting as the principal contractor for a family-run property development, had dug new foundation footings crisscrossing the site without providing designated safe walkways. The Health and Safety Executive described the site as a death trap. Large, unsecured planks were used as makeshift bridges, lacking handrails or adequate lighting. Hustei's body was not discovered until 2:00 PM the following day. Only after the fatal incident and subsequent regulatory enforcement did the company install proper scaffolding framework walkways.

Industry implications

The tragic case highlights the severe legal and moral consequences of failing to secure groundworks. Alchemist DB Limited, which has since gone into liquidation, was sentenced in absentia at Luton Magistrates Court on 29 May 2026. The firm was convicted of breaching Regulation 22 of the Construction (Design and Management) Regulations 2015. Alongside the £20,000 fine, the company was ordered to pay £5,000 in costs. The ruling demonstrates that corporate liquidation will not halt criminal proceedings following a site fatality.

What contractors should do now

Principal contractors must install substantial physical barriers around all excavations where a fall risk exists. Site managers must establish well-lit, dedicated pedestrian walkways using engineered temporary bridges with secure handrails. Open trenches must never be left unguarded, particularly when site boundaries adjoin residential areas or worker accommodation. Site security must explicitly account for out-of-hours hazards and unauthorized access.

Expert view

Health and Safety Executive Inspector Rauf Ahmed noted that the company completely failed to take appropriate precautions to ensure the safety of those moving around the site. The failure to properly sequence groundworks and provide basic pedestrian safety measures demonstrates a catastrophic breakdown in site management. The makeshift use of slippery, bowing planks over deep, water-filled trenches falls drastically short of established industry safety standards.

What happens next

The regulator maintains a zero-tolerance approach to open, unguarded excavations. Inspectors will continue to issue immediate Prohibition Notices where deep trenches lack adequate edge protection. Groundwork contractors must ensure their site security measures are robust enough to prevent both workplace accidents and out-of-hours tragedies.
