UK construction-safety guidance by the Riskora Editorial Team
Electrical installation work on commercial projects carries risks that can kill instantly. Arc flash, electrocution, and fire are ever-present hazards — particularly during first fix, isolation switching, and testing phases. A proper risk assessment is required before your electricians start work, and the principal contractor will expect to see one.

Under the Electricity at Work Regulations 1989 and CDM 2015, all electrical installation work must be preceded by a suitable and sufficient risk assessment. BS 7671 (IET Wiring Regulations) requires that persons carrying out electrical work are competent and that risks are assessed before work begins. On commercial projects, the principal contractor will require the risk assessment as part of the contractor's safety documentation. The assessment must consider live working risks, isolation procedures, and the specific hazards of the installation environment.
An electrical contractor in Leeds is carrying out a full rewire of a three-storey commercial office during an occupied refurbishment. Some areas remain live while others are isolated for works. The principal contractor requires a risk assessment covering all phases from first fix through to testing and commissioning. Using Riskora, the project electrician generates a comprehensive risk assessment — covering isolation procedures, arc flash risks, and coordination with the mechanical contractor — in under 5 minutes.
