How Often Should Electrical Systems Be Inspected in a Commercial Property?

Reflecting on Electrical Fire Safety Week

Last week’s Electrical Fire Safety Week served as a vital reminder about maintaining safe electrical systems in commercial properties. Since electrical faults are a leading cause of workplace fires, regular inspections and maintenance are crucial for compliance, safety, and operational efficiency. How often should businesses check their electrical components? Let’s explore what you need to know.

Routine Electrical Inspections: How Often and Why?

In the UK, electrical inspections in commercial properties must adhere to key regulations such as the Electricity at Work Regulations 1989 and BS 7671 (IET Wiring Regulations). The recommended frequency of inspections varies depending on the type of installation, usage, and industry.

1. Fixed Wire Testing (EICR – Electrical Installation Condition Report)

• How often? Every five years (or more frequently for high-risk environments).
• Why? This thorough assessment identifies deterioration, defects, and potential hazards within the building’s electrical wiring.

2. PAT Testing (Portable Appliance Testing)

• How often? Varies based on equipment type and usage:
  • Office equipment (e.g. computers, printers): Every 2-4 years
  • Handheld equipment (e.g. power tools): Every 6-12 months
  • Construction sites: Every 3 months
• Why? Ensures portable appliances are safe to use, reducing the risk of electrical shocks and fires.

3. Emergency Lighting Inspections

• How often?
  • Monthly: Functional test (brief test to check operation)
  • Annually: Full-duration test (ensures lights function for the required emergency time, typically 3 hours)
• Why? Emergency lighting is critical for safe evacuation during power failures or fires.

4. Fire Alarm System Testing

• How often?
  • Weekly: Alarm sounder test
  • Six-monthly: Professional service by a qualified engineer
  • Annually: Full system inspection
• Why? Ensures early detection of fire hazards and compliance with BS 5839 standards.**

5. Thermal Imaging Surveys

• How often? Annually for high-risk industries or critical electrical systems.
• Why? Detects overheating components before they fail, preventing potential electrical fires.

Why Regular Inspections Matter

Neglecting electrical system maintenance can have severe consequences—from fire hazards and equipment breakdowns to legal violations and business interruptions. Regular inspections safeguard both people and property while ensuring smooth business operations free from unexpected electrical issues.
