Not sure if your electrical problem needs an emergency call-out or can wait? Use this guide to decide — and when in doubt, always call.
A burning smell from sockets, switches, or your consumer unit is a fire warning. Switch off at the mains and call your Cardiff emergency electrician immediately.
Electric shocks indicate a live fault. Do not touch the person if still in contact with the source. Call 999 first, then call us to make the installation safe.
Visible sparks or scorch marks around sockets indicate a dangerous fault. Stop using the socket immediately and call your Cardiff emergency electrician.
A circuit breaker that trips repeatedly is protecting you from a fault. Do not keep resetting it — call a Cardiff emergency electrician to diagnose the cause.
Water ingress near sockets, consumer units, or light fittings is extremely dangerous. Switch off at the mains and call us before restoring power.
Persistent flickering is a sign of a loose connection or overloaded circuit. Not immediately dangerous but should be investigated by a Cardiff electrician.
If one room or area has lost power and resetting the consumer unit doesn't fix it, a circuit fault needs professional diagnosis.
An EICR (Electrical Installation Condition Report) is legally required for rental properties and recommended before purchasing. Book with your Cardiff electrician.
Our Cardiff electricians give honest advice over the phone — no call-out charge for the call itself.
