RCD TestingTesting, Installation & Replacement

A Residual Current Device (RCD) is a life-saving device that instantly cuts power when it detects an electrical fault. It monitors the current flowing in and out of a circuit and trips within milliseconds if it detects an imbalance, preventing fatal electric shocks. RCDs are a critical safety feature in all modern electrical installations across Bedfordshire, and we test and install them throughout Bedford, Luton, Dunstable, and the surrounding areas.

You should test RCDs monthly by pressing the test button on the device. Professional testing should be conducted every 6 months or as part of your periodic electrical inspection (EICR). Regular testing ensures the RCD will operate correctly in an emergency. We offer RCD testing services across all Bedfordshire areas including Bedford, Luton, Dunstable, Leighton Buzzard, Biggleswade, Ampthill, and Flitwick.

An MCB (Miniature Circuit Breaker) protects against overload and short circuits. An RCD protects against earth faults and electric shocks. An RCBO combines both functions in one device, providing comprehensive protection for individual circuits. Modern consumer unit upgrades in Bedfordshire typically use RCBOs for each circuit, meaning if one circuit trips, the rest of your home stays on.

Frequent RCD tripping indicates an electrical fault such as damaged cables, faulty appliances, moisture ingress, or deteriorating insulation. It's a warning sign that shouldn't be ignored. Our electricians provide professional fault-finding across Bedfordshire — covering Bedford, Luton, Dunstable, Leighton Buzzard, Biggleswade, and all surrounding areas — to identify and resolve the underlying problem quickly.

Current 18th Edition wiring regulations require RCD protection for most circuits, especially sockets, outdoor circuits, and bathrooms. Many older properties in Bedfordshire — particularly in Bedford, Luton, and Dunstable — may not have full RCD protection. Upgrading to a modern consumer unit with RCBOs provides the best protection and is often required following an EICR inspection.

A faulty RCD won't protect you from electric shocks, creating a serious safety risk. Regular testing identifies failed RCDs before they're needed in an emergency. If your RCD fails testing, it must be replaced immediately by a qualified electrician. We carry out RCD replacements across all Bedfordshire areas, typically on the same day as testing.

RCD testing in Bedfordshire is typically included as part of an EICR inspection. Standalone RCD testing for landlords or businesses starts from around £75–£150 depending on the number of circuits and devices. We offer competitive rates across Bedford, Luton, Dunstable, Leighton Buzzard, Biggleswade, and all surrounding Bedfordshire areas. Contact us for a free quote.

Yes, RCD testing is part of the mandatory EICR inspection that all Bedfordshire landlords must carry out every 5 years. If your rental property in Bedford, Luton, or Dunstable doesn't have adequate RCD protection, this will be flagged as a C2 (potentially dangerous) code on your EICR, requiring urgent remedial work. We help landlords across Bedfordshire achieve compliance quickly and cost-effectively.

Yes — we cover the entire county of Bedfordshire for RCD testing and installation, including Bedford, Luton, Dunstable, Leighton Buzzard, Biggleswade, Sandy, Ampthill, Flitwick, Kempston, Shefford, Potton, Woburn, and all surrounding villages. We also cover Hertfordshire and Buckinghamshire. Call 07853 318489 for a free quote or to book an appointment.

A 30mA RCD is the standard for personal protection — it trips fast enough to prevent fatal electric shocks. A 100mA RCD is used for fire protection and trips more slowly. In domestic properties across Bedfordshire, 30mA RCDs are required for socket circuits, outdoor circuits, and bathroom circuits. We ensure all RCDs are correctly rated and installed to current BS 7671 standards.

Yes, we replace faulty RCDs and RCBOs across all Bedfordshire areas, typically on the same day as testing. We carry a range of replacement devices to suit all consumer unit types. If your RCD is tripping frequently or failing the test button check, call us on 07853 318489 and we'll arrange a prompt visit to your Bedford, Luton, or Dunstable property.

An RCBO (Residual Current Breaker with Overcurrent protection) combines the functions of an MCB and RCD in a single device. Upgrading to RCBOs means each circuit has its own individual protection — if one circuit trips, the rest of your home stays on. This is the gold standard for electrical safety and is what we install in all new consumer unit upgrades across Bedfordshire.
