Is a mild shock from metal dangerous?

A brief snap from a door handle after friction is consistent with static, not proof. A shock from plumbing or an appliance needs a test even if it was brief. Do not touch it again.

Why only with wet hands?

Wet skin conducts more. A voltage you barely notice when dry can be obvious when wet. That includes both a wiring fault and a small voltage on the supply earth. Stop using the fitting either way.

It might be. Poor bonding, an appliance fault and a supply fault can feel similar. An electrician has to measure it. A rural supply is not, by itself, an explanation.

What if it is only in one room?

Say which room and which objects. If a single appliance was the only source, leave it unplugged. Do not plug everything back in one at a time.

Mild Electric Shock When Touching Metal

A shock from pipes, a window frame or an appliance case needs testing, including when it was brief. A snap from a door handle after friction is only consistent with static, not proof.

What's happening?

Do not touch the metal again to classify it. A brief snap from a door handle after friction is consistent with static, which the static page describes. It is not proof, because a mains contact can be brief too. A shock from pipes, frames or electrical fittings needs assessment even if it was short. Possible causes include an appliance, damaged cable, bonding, or a voltage on the supply earth. The IET notes that a small voltage between the supply earth and the ground can be felt with wet skin, and that a broken combined earth and neutral can put a much higher voltage on the same metalwork.

What usually causes it?

An appliance leaking current to its case or to nearby metal
Damaged cable touching pipework or a metal frame
Bonding that is loose, broken or missing
A small voltage on the supply earth, felt more with wet hands
A broken combined earth and neutral, including via shared pipes

Is it dangerous?

A shock from this metalwork is a warning, whether it lasted or was brief. Wet hands or bare feet can make the same voltage worse. Call 999 if someone is unconscious or not breathing normally. If they seem well, still get a medical assessment: Electrical Safety First says injury, including a disturbed heart rhythm, may not show at once. The static page is for snaps that follow friction, from ordinary handles, not from plumbing or appliances.

Can I fix it myself?

Do not touch the metal again. Unplug an appliance only if its plug and socket are dry, undamaged and easy to reach, and you do not move the appliance or touch its case. Otherwise leave it. Switch off at the consumer unit 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. Switching off does not clear a supply fault on bonded pipes. Call 105 in England, Scotland and Wales and an electrician. Tell them what you touched, whether the shock was brief, whether your hands were wet, and what else did the same.
