Why did the socket shock me?

The plate or the contacts were live at that moment. A loose wire, a damaged cable, a broken plate or a supply fault are possible. The shock does not prove which.

Are metal sockets more dangerous?

A metal plate is designed to have an earth connection. That connection may be missing, or a supply fault may raise the voltage on it. A plastic plate does not conduct in the same way. Either kind can shock you if the contacts or the wiring are damaged. The material does not tell you which fault it is.

Can a faulty socket start a fire?

Loose or worn contacts can overheat. Report discoloration, a burning smell or a plate that was hot. Leave the circuit off and do not open the socket.

I was shocked while plugging something in. What now?

Stop using that socket. Do not keep inserting the plug to confirm it. Isolate the circuit if you can do that safely and have the socket tested.

Why didn't the RCD trip?

It may not. An RCD detects some faults and limits the length of some shocks. HSE is clear that a shock can still cause serious injury. Report that nothing tripped.

Shocks from more than one socket

That can be one circuit or the installation earth, not a single plate. If taps or radiators are involved too, call 105 as well as an electrician.

Is a brief snap from a socket just static?

No. A mains contact can be brief. Stop using the socket and have it tested. Do not touch it again to decide. A snap from a door handle after walking on carpet is a different situation, on the static page, and even that is not proof.

Electric Shock When Touching A Socket

You get a shock from a socket faceplate, or while putting a plug in. Stop using that socket, do not open it, and have it tested. If taps or radiators do the same, call the electricity network on 105 as well.

What's happening?

A socket shock means the plate, the shutters or the contacts were live while you touched them. Shutters stop fingers reaching into the holes. They do nothing if the plate itself is live. Possible causes include a loose connection, damaged cable, a cracked plate, worn contacts, or a wider earth fault if more than one socket does it. A metal plate may be connected to the installation earth, so a supply fault can raise its voltage, or that connection may be missing. The shock does not prove which.

What usually causes it?

A loose connection or damaged cable at the socket
A cracked plate or worn contacts
A metal faceplate affected by an earth or supply fault
The same fault appearing at more than one socket
An appliance with a damaged plug, felt as the plug goes in

Is it dangerous?

Yes. Sockets are at child height, and a shock while inserting a plug can also mean damaged contacts that overheat. A brief tingle is enough to stop using it. Call 999 if someone is unconscious or not breathing normally, and do not touch them while they are still against the socket. If they seem well, still get a medical assessment: Electrical Safety First says injury, including a disturbed heart rhythm, may not show at once.

Can I fix it myself?

Do not use the socket, do not plug anything else in, and do not take the faceplate off. Switch off that circuit, or the main switch if you cannot tell which breaker it is, only if you can reach and operate it without touching suspect metal or standing in water. If you are not sure, keep away and call. Scorch marks or a burning smell are signs to report, not a diagnosis. If taps, radiators or several metal fittings shock you as well, keep off them and call 105 in England, Scotland and Wales as well as an electrician. The main switch does not clear a supply fault on bonded metal. Tell them which socket, whether a plug was going in, whether the plate is metal, whether anything tripped, and whether anyone is hurt.
