Overview
Residual Current Devices (RCDs) are critical components of electrical safety systems — designed to disconnect power instantly when a fault or imbalance is detected.
However, RCDs can fail mechanically, degrade over time, or fall outside required trip-time tolerances without visible warning.
Our NICEIC-certified engineers carry out structured RCD inspection and testing to verify:
- Correct operation
- Compliance with BS 7671 disconnection times
- Ongoing reliability of protective devices
Regular RCD testing supports compliance under:
- BS 7671 (IET Wiring Regulations)
- Electricity at Work Regulations (EAWR)
- Insurer and audit requirements
RCD verification is often delivered alongside full Fixed Wire Testing (EICR) inspections, or as a standalone compliance programme for high-demand sites.
Who This Service Is For
RCD testing is essential for:
Key benefits include:
Manufacturing facilities
Pharmaceutical sites
Warehouses and logistics centres
Commercial offices and retail environments
Facilities managers responsible for electrical compliance
If your site relies on protective devices to prevent shock, fire, or escalation of electrical faults, structured RCD verification is critical.

Case Study
Fixed Wire Testing Takeover — Manufacturing Plant, Ripley, Derbyshire
Challenge:
A large manufacturing facility in Ripley required a full Fixed Wire Testing programme after taking over from a national testing provider.
ElectroGlow identified serious gaps in the existing inspection records, including multiple distribution boards that were missing from previous reports and had not been tested or certified.
The site required an urgent compliance-led approach to restore visibility, safety assurance, and insurer confidence.
Solution:
ElectroGlow carried out a comprehensive site-wide EICR inspection, verifying all distribution boards, final circuits, and fixed electrical infrastructure.
Our engineers:
Re-established accurate board schedules and circuit identification
Completed inspection and testing of previously unrecorded equipment
Issued clear coded observations with prioritised remedial actions
Delivered structured reporting for compliance and insurance submission
Results achieved:
128 C2 observations identified and prioritised for urgent corrective works
195 C3 improvements recorded to support long-term compliance planning
Previously missing distribution boards brought back into certification scope
Full visibility restored across the site’s electrical safety status
Clear compliance roadmap delivered for phased upgrades

Frequently Asked Questions
Answers to common questions about our solar and EV solutions.
How often should RCDs be tested?
RCDs should be manually tested every 6 months using the built-in test button. Professional testing and recorded verification is typically required every 1–3 years, depending on site risk level, operational environment, and insurer requirements.
Can RCD testing be carried out during live operations?
Yes. We regularly work within operational commercial and industrial facilities and can phase testing or schedule out-of-hours and weekend works to minimise disruption.
Will RCD testing interrupt power?
Each RCD must briefly trip to confirm correct operation. We coordinate testing with site teams to ensure controlled, minimal impact on protected circuits.
Will the documentation be suitable for insurers and audits?
Yes. All testing is completed to NICEIC standards, with clear reporting and certification suitable for compliance audits, insurers, and internal safety records.
Do you carry out remedial works if defects are identified?
Yes. Where faults or non-compliances are identified, we can complete corrective works efficiently, re-test affected circuits, and issue updated certification.
Ensure every protective device on your site is verified, documented, and compliant.
