One socket has stopped working but the others in the room haven't: why

Is the socket actually on a switch

Many Estonian flats, especially newer builds and renovated Soviet-era panel flats, wire one or two sockets in a room to a wall switch — often meant for a lamp or a designated appliance socket near a desk. If that switch has been knocked off, or someone turned it off deliberately months ago and forgot, the socket reads as simply dead.

Walk the room and look for a switch that does not obviously control the ceiling light. Light switches by the door sometimes control a socket instead of, or as well as, the light. Flick anything that looks like it might be relevant and test the socket again before assuming a fault.

A simple test with a device you trust

Before deciding the socket is faulty, rule out the device you first tried it with. Plug something you know works — a phone charger with a visible light, or a lamp — into the dead socket. If it stays dead, try the same device in a socket you know is live, to confirm the device itself is not the problem.

If you have a simple plug-in socket tester, that is a faster way to check, but a known-good lamp does the job perfectly well. This takes two minutes and saves a call-out for a fault that turns out to be a broken extension lead or a dead lamp bulb.

How one loose joint can cut off a whole chain of sockets

Sockets in a room are usually wired in a ring or a daisy chain: cable runs from one socket to the next, and each one passes the connection on to the following one. If a connection at one socket works loose — a screw terminal that was never quite tight, or a connector that has vibrated over years — everything downstream of that point loses power, while everything before it stays live.

This is why one dead socket with working neighbours either side is not unusual: the fault is not necessarily at the dead socket itself, it can be at the last working one, where the connection feeding the next link in the chain has failed. Tracing which socket that is from outside the wall is not straightforward, which is the main reason this fault needs an electrician rather than guesswork.

What is safe to check yourself

A few checks are safe and worth doing before you call anyone, because they solve the problem in a fair number of cases without opening anything up.

Beyond this, do not remove the socket faceplate or poke at the wiring. A loose connection under a live faceplate is exactly the kind of thing that causes a shock or a small arc, and it is not obvious from the outside which wire is at fault.

• Check for a nearby switch controlling that socket specifically
• Test with a lamp or charger you know works, in the dead socket and then a live one
• Check the fuse or breaker box for anything showing an odd position, even if nothing has tripped
• If it is on an extension lead or power strip, test the socket in the wall directly instead
• Note which sockets in the room still work, so you can describe the pattern when you call

When to call at once rather than wait

A single dead socket with no other symptoms is rarely urgent, and it is reasonable to live with it for a few days if you have other sockets to use. It becomes a call-now situation if you notice a burning smell, scorch marks on the faceplate, a crackling sound when you plug something in, or if the socket has ever felt warm.

Those signs point to heat at a connection, which is a fire risk rather than a convenience issue, and are different from a socket that is simply dead. We are on call for genuinely urgent electrical faults in Tallinn and Harju county, any day of the week.

What an electrician actually does to fix it

For a dead socket with no other symptoms, an electrician isolates the circuit, opens the socket and the one before it in the chain, and checks each terminal for a loose or corroded connection. Tightening or remaking one joint usually restores power to everything downstream, and the whole visit is often under an hour.

Electrical work is charged from 49 € an hour with a 25 € call-out in Tallinn that comes off the bill if the job goes ahead. If the socket itself turns out to be worn or scorched inside and needs replacing rather than reconnecting, that is a socket installation from 35 € per job, and either way the work carries our 24-month guarantee.
