Fencing firm fined £10,000 after worker suffers severe burns in live cable strike
City Fencing Contractors Limited was fined £10,000 on 26 May 2026 after a worker struck a live underground electrical cable during a project in Manchester. The incident left the operative with severe burns and highlights systemic failures in pre-excavation site surveys. The prosecution serves as an immediate warning to all groundworks and fencing contractors regarding the absolute necessity of accurate utility mapping before breaking ground.
Background
The injured employee was digging on site when his tool penetrated an unmarked live electrical cable, resulting in an immediate arc flash and severe thermal burns. An investigation by the Health and Safety Executive (HSE) revealed that City Fencing Contractors Limited, based in Liverpool, had failed to implement suitable controls to detect and avoid underground services. The regulator concluded that the contractor had not taken reasonable steps to locate the cables before authorising the digging operation. The company pleaded guilty at Warrington Magistrates' Court to breaching Regulation 25(4) of the Construction (Design and Management) Regulations 2015. They were ordered to pay £5,487 in costs alongside the £10,000 fine.
Industry implications
Striking underground utilities remains a highly prevalent and dangerous issue in UK construction. This judgment reinforces that relying on visual checks or outdated utility plans is not legally sufficient. Under the current regulatory framework, principal contractors and subcontractors share the duty to ensure excavation works do not create health and safety risks from existing underground services. A failure to locate and isolate these services before breaking ground leaves directors entirely exposed to criminal conviction and financial penalties.
What contractors should do now
Site managers must secure up-to-date service plans from local utility providers before any excavation begins. Groundworkers must be equipped with calibrated cable avoidance tools and receive regular, formal training in their safe use. Contractors must adopt recognised safe digging practices. This includes using insulated hand tools carefully near suspected utility lines instead of mechanical excavators. Trial holes should be used to confirm the exact depth and location of cables before general excavation commences.
Analysis
HSE inspector John Padfield told the court that underground services represent a significant risk across all construction environments. "It is important measures are taken to identify them before any excavation work is undertaken," Padfield stated. "Had the company implemented an effective safe system of work following HSE guidance, this incident would not have occurred." The decision to prosecute for this specific breach demonstrates a low tolerance for preventable cable strikes. The incident could easily have been fatal, a point the prosecution heavily emphasised during sentencing.
What happens next
The HSE continues to promote its safe digging guidance as a core focus of site inspections. Fencing and groundworks companies can expect increased scrutiny of their utility mapping protocols. Site audits will likely require immediate proof of utility diagrams and evidence of formal cable avoidance training for all active excavation teams.
