Workplace Electrical Safety Statistics UK: 2026 Facts, Data & Key Insights

Electrical Safety in the Workplace

Every UK employer has a legal duty to ensure that electrical equipment and installations in their workplace are safe. This duty, set out in the Electricity at Work Regulations 1989, is not conditional on the size of the business, the sector, or the perceived level of electrical risk — it applies universally, from a single-person office with a laptop and a kettle to a large industrial facility with high-voltage machinery.

Yet electrical safety remains one of the most consistently undermanaged workplace hazards. The combination of its invisibility, the misperception that modern equipment is inherently safe, and a widespread misunderstanding of what the law actually requires means that thousands of UK workplaces carry preventable electrical risk at any given time.

This guide brings together the latest verified data on workplace electrical safety in the UK. For the overall picture of electrical accidents, see our Electrical Accident Statistics UK guide.

Key Facts & Figures (Overview)

The Legal Framework for Workplace Electrical Safety

The Electricity at Work Regulations 1989 is the primary legislation governing electrical safety in UK workplaces. Key duties include:

The Health and Safety at Work etc. Act 1974 imposes the general employer duty to provide safe equipment and a safe working environment.

The Provision and Use of Work Equipment Regulations 1998 (PUWER) require all work equipment — including electrical equipment — to be suitable for its purpose, properly maintained, and used only by trained and competent workers.

Taken together, these regulations create an unambiguous duty for all UK employers to ensure their electrical equipment — fixed and portable — is regularly inspected, tested, and maintained by competent persons.

Electrical Accidents by Sector

HSE and RIDDOR data identifies the sectors with the highest rates of workplace electrical incidents:

Construction is consistently the highest-risk sector for electrical fatalities. Contact with overhead and underground power lines during groundwork and excavation, temporary electrical installations on dynamic sites, and work near live electrical systems are all significant hazard scenarios. Construction accounts for a disproportionate share of the approximately 30 annual workplace electrical fatalities.

Manufacturing involves sustained operation of complex electrical machinery, high-voltage equipment, and industrial processes with significant electrical risk. Arc flash — the release of electrical energy through an unintended arc — is a particular manufacturing hazard capable of causing severe burns and fatalities.

Agriculture faces specific risk from overhead power lines crossing farmland. Agricultural machinery — particularly during harvesting — can make contact with overhead lines, causing fatal electrocution. The combination of outdoor working, large mobile machinery, and the presence of water further elevates agricultural electrical risk.

Maintenance and facilities management workers interact regularly with electrical plant, switchgear, and fixed installations. Electrical work on live systems — even briefly — is among the highest-risk workplace activities.

Retail and food service — while not typically associated with high electrical risk — generate a disproportionate share of electrical fire incidents due to extended operating hours, high-density use of kitchen appliances, and electrical installations under sustained load.

Workplace Fires by Sector

The 2024/25 MHCLG workplace fire statistics provide detailed sector breakdowns:

Industrial premises: ~25% of workplace fires (approx. 1,666 fires) The highest-risk category, driven by flammable materials, high-temperature processes, heavy machinery, and complex electrical systems under sustained load.

Food and drink premises: ~19% (~1,263 fires) Commercial kitchens, restaurants, cafes, and takeaway outlets. Cooking is the primary cause but electrical faults in catering equipment contribute significantly.

Retail: ~18% (~1,200 fires) Electrical installations, combustible stock, back-of-house storage, and long trading hours.

Hospitality: 7.6% (505 fires)

Education: 6.3% (417 fires) See our School Electrical Safety Statistics UK guide for full data.

Healthcare: 6.5% (433 fires) See our Care Home Electrical Safety Statistics UK guide.

Offices: 5.2% (348 fires) Despite appearing lower-risk, office environments carry significant electrical risk from dense concentrations of IT equipment, charging devices, and kitchen appliances. See our Office Electrical Safety Statistics UK guide.

What Causes Workplace Electrical Accidents

Analysis of HSE investigations and RIDDOR incident data identifies consistent patterns in the root causes of workplace electrical accidents:

Contact with live conductors — the most common fatal electrical accident scenario. This includes contact with overhead cables, live wires in fixed installations, and live terminals in equipment under repair or maintenance.

Faulty electrical equipment — portable and fixed equipment with damaged cables, inadequate insulation, or mechanical failure creating live exposed parts. Regular inspection and testing is the principal preventive control.

Inadequate maintenance — electrical systems that have not been inspected or tested at appropriate intervals, allowing deterioration to reach the point of danger before being identified.

Unsafe working practices — working on live systems when working dead is feasible, failure to use appropriate personal protective equipment, and inadequate isolation of electrical systems before maintenance work.

Overloaded circuits and extension leads — particularly in offices and retail environments where the electrical demand has grown beyond the original installation design, creating fire risk through sustained overloading.

Inadequate competence — electrical work carried out by unqualified or undertrained individuals. The Electricity at Work Regulations require only competent persons to work on electrical systems — competence that must be demonstrated through qualifications such as those offered by City & Guilds and LCL Awards.

Electrical Safety Compliance and Inspection

UK employers have two principal obligations for maintaining electrical safety:

Electrical Installation Condition Reports (EICRs): EICR testing of fixed wiring is the primary mechanism for assessing the safety of a building’s permanent electrical infrastructure — wiring, consumer units, distribution boards, circuits, and fixed equipment. For commercial properties, EICRs are typically recommended every 5 years.

Portable Appliance Testing (PAT): PAT testing of portable and moveable electrical equipment addresses the other major category of electrical risk. Under the Electricity at Work Regulations, employers must maintain portable appliances to prevent danger — and PAT testing is the standard mechanism for discharging this duty. See our Portable Appliance Testing Statistics UK guide for full data on PAT testing frequency, failure rates, and what the testing reveals.

The Consequences of Non-Compliance

Failure to maintain electrical safety in the workplace carries both regulatory and financial consequences:

Criminal prosecution: Breaches of the Electricity at Work Regulations can result in unlimited fines and up to two years’ imprisonment for responsible individuals.

HSE investigation: Any workplace electrical incident that results in injury or death triggers an HSE investigation. Where inadequate maintenance, lack of testing, or unsafe working practices are identified, prosecution typically follows.

Insurance invalidation: Many commercial insurance policies require evidence of EICR and PAT compliance. Failure to maintain appropriate records of electrical inspection and testing can result in claims being refused following a fire or electrical incident.

Civil liability: Workers injured due to inadequate electrical maintenance can bring civil claims against employers. The cost of defending and settling such claims can far exceed the cost of the inspection and testing programme that would have prevented the incident.
