What Is Commercial Electrical Testing & Inspection?

Commercial electrical testing and inspections ensure the safety and efficiency of electrical systems in workplaces. Poorly installed or maintained equipment can lead to issues which pose serious risks to life and property, such as:

  • Faulty wiring
  • Appliances, sockets or fuse boxes overheating
  • Damaged cables
  • Power surges

Regular inspections help identify and address these issues early, ensuring safety in the work environment for staff and customers.

What Is An Electrical Installation Condition Report (EICR)?

An EICR assesses the condition of a building’s electrical systems, including wiring, sockets, and consumer units. It involves:

  • Visual inspection: checks for signs of damage, wear, or hazards
  • Dead testing: ensures circuits are correctly connected and not damaged
  • Live testing: verifies the performance of circuits under normal operation
  • Earthing and bonding checks: ensures excess electrical energy is safely redirected

Upon completion, an EICR report categorises findings as satisfactory or unsatisfactory, along with recommendations for repairs or upgrades if necessary.

How Often Should A Commercial Property Be Electrically Tested?

The frequency of electrical testing, known as an EICR (Electrical Installation Condition Report), varies depending on the type of commercial premises. Certain premises may need more frequent EICRs due to their nature or usage. High-risk environments like industrial facilities or buildings with complex systems often require regular inspections. Similarly, hotels, offices, or properties with frequent electrical changes or additions benefit from more frequent assessments to ensure safety and compliance.

It is generally recommended that:

  • Office buildings and shops: every 5 years
  • Industrial facilities: every 3 years or sooner
  • Hotels and rental properties: every 1-3 years depending on risk assessment

Additional inspections should also be conducted:

  • After electrical alterations: to verify the safety of modified systems
  • Following electrical incidents: such as fires, equipment failures, or power surges
  • Before new occupancy: to ensure installations are safe for incoming tenants

Why Is Regular Electrical Testing Important?

Winter can accelerate wear and tear on electrical systems due to freezing temperatures, condensation, and increased energy demand from heaters and lights. Regular testing helps to:

  • Prevent hazards: identify risks that could lead to fires or electrocution
  • Protect equipment: detect faults early to avoid damage to appliances and reduce downtime
  • Ensure compliance: demonstrate adherence to safety standards and legal requirements, such as the Health and Safety at Work Act (1974)
  • Maintain insurance coverage: meet the conditions required for insurance policies

Why Is Checking Electrical Systems Crucial During Winter?

Colder temperatures can worsen issues like damaged cables, faulty wiring, and overloaded circuits, making regular electrical checks essential. At Datel Electrical, our expert electricians conduct thorough fault finding during testing or an EICR to ensure your building’s electrical installations are safe and compliant. This includes:

  • Consumer units: fuse boxes or distribution boards
  • Cabling: wiring systems that distribute power throughout the property
  • Accessories: sockets, switches, light fittings, and other electrical components

How Much Does A Commercial EICR Cost?

The cost of a commercial EICR depends on several factors:

  • Building size: larger buildings with more rooms typically cost more
  • Number of circuits: more circuits increase the complexity and cost
  • Accessibility: easily accessible circuits reduce costs, while hard-to-reach ones may increase them
  • Circuit board complexity: larger or more intricate boards can add to the expense

Legal Requirements For Commercial Electrical Testing In The UK

Under the Electricity at Work Regulations (1989), employers and landlords are legally responsible for ensuring the safety of electrical equipment and installations in their properties. This includes:

  • Periodic inspections: ensuring that fixed electrical systems comply with BS 7671 standards for design, installation, and maintenance
  • Portable Appliance Testing (PAT): regular testing of portable electrical appliances, with the frequency determined by the type of equipment and its environment

Failure to comply with these legal requirements can lead to significant consequences, including:

  • Legal liability: employers or landlords may face compensation claims if faulty electrics cause injury or damage
  • Regulatory penalties: non-compliance with safety regulations can result in fines or other penalties
  • Insurance issues: many policies require regular testing as a condition for coverage. Without it, claims may be invalidated
