UK households are being urged to press one button before the clocks go back this weekend, as Daylight Saving Time officially ends on Sunday, October 25, at 2am, when clocks will go back an hour to 1am. The seasonal change provides an extra hour in bed, but electrical certification body NICEIC is using the occasion to remind homeowners to test their residual-current device (RCD).
Why Testing Your RCD Matters
An RCD is a safety switch that automatically cuts off electricity when it detects a certain type of electrical fault, helping to protect against electric shocks and reduce the risk of electrical fires. British Standards state that RCDs should be tested every six months, making the clock change an easy reminder for this important household check.
Research from NICEIC's recent electrical safety campaign found that 22% of homeowners had not had their electrics checked by a professional in more than 10 years, if ever. A further 16% did not know whether their electrics had ever been professionally inspected, highlighting how easily important electrical safety checks can slip under the radar.
How to Test Your RCD
Testing an RCD is straightforward: simply press the 'Test' button on the device, which should trip the switch and cut off power to the circuits it protects. If it doesn't trip, homeowners are advised to contact an NICEIC-registered electrician to investigate.
While RCDs are a vital first line of defence, they should sit alongside good electrical safety habits to help reduce the risk of a fire starting in the first place. Warning signs such as scorch marks around socket-outlets, burning smells, buzzing sounds, unusually warm fittings, flickering lights, or circuit breakers that repeatedly trip or fuses that regularly blow could indicate an underlying fault.
Expert Advice and Next Steps
Paul Collins, Technical Integrity and Standards Director at NICEIC, commented: "We all have little jobs around the house that are easy to put off, but checking your RCD shouldn't be one of them. These devices play an important role in protecting your household from electrical danger, and testing them takes just a few moments."
He added: "The clocks changing is an easy way to remember to carry out this simple check twice a year. If your RCD doesn't trip when tested, or you notice signs of electrical damage or deterioration, don't ignore them. Contact a registered electrician to get things checked out."
For homeowners unsure about the condition of their electrics, an Electrical Installation Condition Report (EICR) can help identify potential problems with the property's fixed electrical installation. Similar to an MOT for home electrics, it involves a professional assessment to determine whether the installation is in a satisfactory condition for continued use and whether remedial work is needed.
