Plug Socket Not Working: How to Fix Dead Outlets

Why Has My Socket Stopped Working?

A dead socket is frustrating, but the cause is usually identifiable. Before calling an electrician, try these troubleshooting steps.

Quick Checks First

Common Causes and Solutions

1. Tripped Circuit Breaker

The most common cause - and the easiest fix.

How to Check:

• Go to your consumer unit (fuse board)
• Look for switches in the 'off' or middle position
• Push any tripped switches firmly to 'on'
• Test the socket

If It Trips Again:

• Something on that circuit has a fault
• Unplug everything and reset
• Plug items back one at a time to find the culprit

2. Tripped RCD

Similar to above, but the larger RCD switch:

• Protects multiple circuits
• Will cut power to several sockets
• Reset the same way

Keep Tripping? See our guide on RCD troubleshooting.

3. Socket Switch Turned Off

Sounds obvious, but easily overlooked:

• Check the switch on the socket itself
• Some double sockets have independent switches
• Switch may be stiff or stuck

4. Faulty Appliance

The appliance, not the socket, may be the problem:

Test by:

• Trying appliance in a different socket
• Trying different appliance in 'dead' socket
• Checking appliance fuse

5. Blown Fuse in Plug

Older appliances and high-power devices have fuses:

How to Check:

• Remove plug from socket
• Unscrew fuse carrier (if visible) or open plug
• Test fuse with multimeter or replace with known good fuse
• Replace with correct rating (3A or 13A typically)

6. Faulty Socket

Sockets can fail due to:

• Worn internal contacts
• Loose terminal connections
• Overheating damage
• Physical damage to faceplate

Signs of Socket Failure:

• Socket warm to touch
• Burn marks around outlet
• Plug fits loosely
• Socket works intermittently

Solution: Replace socket (electrician recommended)

7. Wiring Fault

More serious causes:

• Cable damage (rodents, screws, age)
• Junction box failure
• Loose connections in back of socket
• Damaged cable in wall

Requires professional investigation.

The Ring Circuit Problem

How Socket Circuits Work

Most UK homes use ring circuits:

• Cable loops from consumer unit through all sockets and back
• Each socket is part of the chain
• One break can affect multiple sockets

Finding Ring Faults

If several sockets are dead:

• They may be on the same ring
• Break in the ring kills sockets 'downstream'
• Requires electrician to trace and repair

Spur Sockets

What's a Spur?

Some sockets are 'spurred' off the ring:

• Connected to the ring at one point only
• If spur cable fails, only that socket dies
• Easier to diagnose than ring faults

Signs of Spur Failure:

• Single socket dead
• Ring circuit working fine
• Cable damage between ring and spur

When to Call an Electrician

Definitely Call If:

• Multiple sockets dead (and not tripped breaker)
• Burning smell from socket
• Scorch marks visible
• Socket feels hot
• Buzzing or crackling sounds
• Breaker keeps tripping when reset
• You're not confident working safely

Safe for DIY

Only if you're competent:

• Replacing plug fuses
• Resetting tripped breakers
• Testing different appliances
• Tightening face plate screws (power off!)

Testing a Socket

Basic Testing

With a socket tester (available from hardware stores):

• Plug tester into socket
• Read LED pattern
• Compare to guide on tester
• Identifies common wiring faults

What Testers Show

Socket testers cost £10-20 and are worth having.

Common Fixes and Costs

Preventing Socket Problems

Regular Checks

• Don't overload sockets
• Avoid using damaged plugs
• Check sockets aren't loose
• Look for discolouration

Warning Signs

Call before complete failure if you notice:

• Sockets feeling warm
• Plugs difficult to insert/remove
• Intermittent connection
• Clicking sounds
• Burning smell (even briefly)

Frequently Asked Questions

Why does only one socket not work?

Often a local issue: faulty socket, spur connection, or the socket's switch. If others work, it's not the circuit breaker.

Can I replace a socket myself?

Legally, you can replace a socket like-for-like in most rooms. But we recommend professional installation for safety.

Why did my socket work and then stop?

Connections can loosen over time, sockets wear out, or cables can be damaged. Something has changed - find out what.

My extension lead doesn't work in this socket - why?

Try the extension in another socket. If it works, the original socket may have worn contacts that don't grip well.
