Professional RCD Residual Current Device Testing in Surrey & West London Properties
Your Residual Current Device (RCD) is the silent guardian that cuts power in milliseconds if it detects even a tiny leak of current to earth — the kind of leak that could flow through your body and cause serious injury or death. But RCDs can fail over time: contacts wear out, electronics degrade, and mechanisms become sticky. ElectraWorks Ltd provides professional RCD testing across Surrey, Epsom, Leatherhead, Cobham, Esher, Walton-on-Thames, and West London using calibrated test equipment.
Mark measures both tripping time and tripping current against BS 7671 requirements, testing every RCD at multiple ratings and recording the results. Any device that fails is clearly identified for replacement with a modern, sensitive unit. NAPIT certified and City & Guilds qualified, Mark's testing gives you certainty that your protection is real — not assumed. Full documentation is provided for your records, your insurer, and your EICR requirements.
RCD Testing & Maintenance
Professional testing and replacement services for residual current devices across Surrey and West London.
Functional RCD Testing
Every RCD in your property is tested for correct tripping time and tripping current using calibrated test equipment. A slow or insensitive RCD may not protect you when it matters most.
Residential RCD Checks
Regular RCD testing for homeowners ensures your residual current devices are working correctly in kitchens, bathrooms, gardens, and all circuits requiring additional protection.
Commercial & Rental Testing
Landlords and businesses must ensure RCDs are operational. Mark provides scheduled testing, documented results, and replacement of faulty devices to keep you compliant.
Faulty RCD Replacement
RCDs that fail testing are replaced with modern, sensitive devices that meet current standards. Mark selects the right type and rating for each circuit and installs safely.
RCD Testing by a Qualified Professional
The monthly test button on your RCD is useful, but it is not a substitute for professional testing with calibrated equipment. Mark's RCD testing service across Surrey and West London measures the actual tripping time and current under controlled conditions, giving you certainty that your protection is real — not assumed. NAPIT certification and City & Guilds qualifications back every test, and full documentation is provided for your records, your insurer, and your EICR requirements.
