Electrical Warning Signs at Home | What to Do Safely

Choose the right response

Some signs need immediate action.

Emergency

Smoke, fire, sparking or exposed live parts

Keep away. If there is a fire or immediate danger to life, get out, stay out and call 999. Do not use water on electrical equipment.

Urgent

Burning smell, scorching, melting or unusual heat

Stop using the affected item or circuit if this can be done safely. Do not touch damaged or hot parts. Arrange prompt professional help.

Investigate

Repeated tripping, buzzing, flickering or intermittent power

These can indicate a fault, loose connection, moisture, overload or failing equipment. Record what was operating and arrange fault-finding.

Six signs to recognise

What the home may be telling you.

Burning smell or scorchingMay indicate overheating, arcing, a loose connection or damaged equipment.

Buzzing or cracklingSounds from a socket, switch, light fitting or consumer unit should be investigated.

Repeated protective-device tripsAn RCD, RCBO or circuit breaker is responding to a condition that should not be bypassed.

Flickering or intermittent powerCould relate to a lamp or appliance, but repeated or widespread symptoms need attention.

Shock or tingling sensationStop using the equipment or area and arrange urgent advice. Even a mild shock matters.

Damage or exposed partsCracked sockets, cut cables, loose accessories and accessible conductors must be made safe.

What to do safely

Observe, isolate only if safe, then explain what happened.

01
Keep people awayDo not touch exposed conductors, damaged accessories, wet electrical equipment or anyone still in contact with electricity.
02
Switch off only when it is safeUse the normal appliance switch, plug or consumer-unit control only if there is no heat, damage, water or other immediate danger.
03
Note what was happeningWhich room, circuit or appliance was in use? Was there a smell, noise, flash, trip or loss of power?
04
Send a photograph from a safe distanceA clear image can help plan the visit, but never move a cover, cable or damaged part to obtain it.

Do not tape over damage, fit a larger fuse, hold a breaker on, bypass an RCD or open electrical enclosures. These actions remove protection rather than solving the fault.

Common questions

What homeowners usually ask.

Is a warm plug or socket normal?

Some high-power equipment may produce slight warmth at the plug, but unusual heat, a hot socket, discolouration, a burning smell or melting is a warning sign. Stop using it if safe and arrange investigation.

Can I keep resetting a breaker that trips?

No. The device may be disconnecting an overload, leakage or fault. If it trips again, will not reset or the cause is not obvious, leave the affected circuit off and arrange fault-finding.

What should I do after an electric shock?

Move away from the source and seek appropriate medical advice. If someone is still in contact with electricity, do not touch them; isolate the supply only if it is safe and call 999 in an emergency.
