My RCD keeps tripping — what should I do? +
An RCD that keeps tripping is detecting an earth leakage fault, which could be a sign of damaged wiring or a faulty appliance. Start by unplugging all appliances on the affected circuit, then reset the RCD. Plug each appliance back in one at a time to identify the culprit. If the RCD trips with nothing plugged in, the fault is in the fixed wiring and you need an electrician in Perth to trace and repair it.
How often should I have my electrics inspected? +
The IET Wiring Regulations recommend an electrical inspection (EICR) every 10 years for owner-occupied homes, every 5 years for rented properties (this is a legal requirement for landlords), and every 5 years for commercial premises. If your home was built before 1980 or has never been inspected, it is worth booking an EICR sooner. The inspection will identify any deteriorated wiring, missing earthing, or outdated components.
How long does a consumer unit replacement take? +
A consumer unit replacement in Perth usually takes 4 to 8 hours, depending on the number of circuits and the condition of the existing wiring. Your electricity supply will be off for most of this time, so plan accordingly — charge phones, fill flasks, and move any frozen food to a cool bag. The electrician will test every circuit before restoring power.
Do I get a certificate after electrical work is completed? +
Yes — for any notifiable electrical work (new circuits, consumer unit replacements, bathroom/kitchen installations), your electrician must issue an Electrical Installation Certificate and notify your local building control. For smaller jobs like replacing a socket or light fitting, you should receive a Minor Electrical Installation Works Certificate. Keep these certificates safe as you will need them when selling your property.
What is Part P and why does it matter? +
Part P of the Building Regulations covers electrical safety in dwellings. Certain types of electrical work — including new circuits, consumer unit replacements, and work in bathrooms or kitchens — are classed as notifiable and must either be carried out by a Part P registered electrician or inspected by building control. Using a registered electrician saves you the building control fee (typically £200–£300) and ensures the work is properly certified.
What should I do if I smell burning from a socket or switch? +
Switch off the circuit at the consumer unit immediately and unplug everything from the affected socket. Do not use the socket again until it has been inspected by a qualified electrician. A burning smell from electrical fittings usually indicates overheating caused by loose connections, overloaded circuits, or deteriorated wiring — all of which are fire hazards. Call an emergency electrician in Perth straight away.
