Electrical Problem

Socket Not Working?

A dead socket can indicate a simple fix or a more serious wiring issue. Our CHAS approved electricians quickly diagnose and repair all socket problems.

Why Is My Socket Not Working?

Before you call anyone, check your consumer unit. Look for an MCB (miniature circuit breaker) that's flipped to the 'off' or middle position – this is the most common reason a socket goes dead. Push it firmly back to 'on'. If it trips again immediately, stop there – you've got an active fault that needs professional diagnosis.

If the breaker holds but the socket still won't work, the issue is likely at the socket itself. We see this regularly in Devon properties – particularly in 1960s–80s builds where the original wiring used PVC cables that become brittle over decades. The terminal screws loosen, the conductor oxidises, and eventually the connection fails. In ring circuits (which supply most UK sockets), a break at one point can knock out several outlets because the circuit can no longer 'loop' properly.

When we attend a dead socket callout, we test continuity on the ring circuit using a multifunction tester, check insulation resistance, and inspect the socket's back box for signs of overheating or arcing. Nine times out of ten, it's a straightforward fix – but occasionally we uncover deeper issues like rodent-damaged cables in the cavity or a failed spur connection hidden behind plasterboard.

Common Causes of Dead Sockets

Tripped Circuit Breaker

Low Risk

The circuit protecting that socket may have tripped in your consumer unit. Check for switches in the 'off' position.

Solution:Reset the MCB in your consumer unit. If it trips again, call an electrician.

Loose Wiring Connection

Medium Risk

Wires can work loose over time, especially in older properties or heavily-used sockets.

Solution:Professional tightening of connections and inspection

Damaged Socket Face

Medium Risk

Physical damage to the socket itself can break internal connections and create hazards.

Solution:Socket replacement by qualified electrician

Broken Back Box

Medium Risk

The metal or plastic box behind the socket may be cracked or damaged, affecting the installation.

Solution:Back box replacement and socket reinstallation

Faulty Wiring in Wall

High Risk

Damaged cables within the wall due to rodent activity, DIY damage, or deterioration.

Solution:Cable tracing and repair or replacement

Failed RCD Protection

High Risk

If the socket is on an RCD-protected circuit, the RCD may have tripped or failed.

Solution:RCD testing and potential replacement

When to Call an Electrician

  • Multiple sockets on the same circuit aren't working
  • You've reset the breaker but the socket still doesn't work
  • The socket feels warm or shows discolouration
  • You can smell burning near the socket
  • The socket is in a kitchen or bathroom
  • Plugs spark when inserted into the socket

Frequently Asked Questions

Why is my socket not working but others are?

A single socket not working usually indicates a loose connection, faulty socket, or that specific socket's circuit has tripped. Check your consumer unit for tripped switches. If resetting doesn't help, you'll need an electrician to diagnose the issue.

Can a dead socket be dangerous?

While a completely dead socket isn't typically dangerous on its own, the cause might be. Loose connections can cause arcing and overheating, which are fire risks. It's important to have non-working sockets investigated by a qualified electrician.

How much does it cost to fix a broken socket?

Simple socket replacement typically costs £50-£80 including parts. If the issue is faulty wiring behind the socket, costs range from £80-£150. Complex rewiring work would be quoted separately after inspection.

Frequently Asked Questions

Why has my socket stopped working?

Common causes include a tripped MCB, loose connections behind the socket plate, a failed socket mechanism, or a break in the ring circuit wiring. Check your consumer unit first for any tripped switches.

How much does it cost to fix a dead socket?

Diagnosis starts at £80 plus VAT. Replacing a faulty socket costs £80-£120. If the issue is a broken ring circuit or loose connection in the wiring, repair costs range from £100-£300.

Is a dead socket dangerous?

A single dead socket isn't usually dangerous, but it can indicate wiring issues that should be investigated. If the socket is warm, discoloured, or smells of burning, turn off the circuit and call us immediately.

Can you add new sockets to my home?

Yes, we install additional sockets throughout Devon homes. Double sockets, USB charging points, outdoor sockets, and dedicated circuits for home offices and workshops.
