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 Cambridge straight away.
Is a tripping circuit breaker dangerous? +
A circuit breaker that trips occasionally is doing its job — protecting you from overcurrent. However, frequent or immediate tripping indicates an underlying fault such as a short circuit, overloaded ring main, or deteriorated cable insulation. Do not simply keep resetting it, as this bypasses the protection that is keeping you safe. Have an electrician in Cambridge diagnose the cause before using the circuit again.
What should I do if a socket is sparking? +
Stop using the socket immediately and switch off the circuit at the consumer unit. Sparking when plugging in can sometimes be normal (a brief blue flash), but persistent sparking, blackening around the socket, or a crackling sound indicates a serious wiring fault. Do not attempt to remove the socket faceplate yourself — call a qualified electrician in Cambridge to inspect and repair it safely.
Will the electrician give me a quote before starting work? +
Yes — a professional electrician will diagnose the fault and provide a clear quote before beginning any repair work. For emergency call-outs, they will explain the call-out fee upfront and then quote for the repair once the fault has been identified. You should receive a Minor Electrical Installation Works Certificate or full Electrical Installation Certificate depending on the scope of the job.
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.
Why do my lights flicker in Cambridge? +
Occasional flickering is usually caused by a loose bulb or a poor connection at the light fitting. Persistent flickering across multiple lights can indicate a loose neutral connection at the consumer unit, a faulty main switch, or an issue with the incoming supply. If all lights in your home flicker simultaneously, this could be a supply-side issue — contact your DNO first. Otherwise, have an electrician in Cambridge check the connections at your consumer unit.
