Why Regular Safety Device Testing Matters
Many electrical protection devices fail silently — they appear intact but won't trip under fault conditions
Legal Compliance
BS 7671 and the Electricity at Work Regulations 1989 require all protective devices to be maintained in effective working order.
Fire Prevention
Faulty RCDs and MCBs that fail to trip under fault conditions are a significant cause of electrical fires in commercial premises.
Staff & Occupant Safety
RCDs that don't trip within the required 40ms provide no protection against electric shock — regular testing is essential.
Insurance Validity
Most commercial insurers require evidence of regular safety device testing as a condition of buildings and contents cover.
Preventive Maintenance
Identifying worn or underperforming devices before they fail completely avoids emergency callouts and costly downtime.
Scheduled Testing
We set up quarterly or annual testing schedules that fit around your operations — minimising disruption to your business.
