If one socket has stopped working while others still operate normally, the fault is usually local to that socket or its wiring path.
If you’re unsure where the fault is, using a simple Socket tester can quickly help identify whether the issue is with the socket, appliance, or wiring.
Common Reasons why Socket Not Working but Others Are Fine
Single-socket faults are often caused by loose or failed connections.
- Faulty socket outlet
- Loose wiring behind the socket
- Failed spur connection
- Loose connection in another socket on the ring
- Cable damage
- Partial circuit fault
Safe Checks You Can Carry Out
You can perform simple checks before calling an electrician.
- Test the socket with a different appliance
- Check nearby sockets for power
- Check the consumer unit for tripped breakers
- Do not remove the socket faceplate unless competent
- Use a Socket tester to quickly confirm whether the socket is wired correctly — this can immediately rule out common faults without needing to remove the socket.
If you’re comfortable carrying out basic checks, using a simple tester can help quickly identify whether the fault is with the socket, appliance, or wiring.
Before calling an electrician, many common electrical faults can be quickly identified using a few simple tools at home. These are the same types of testers electricians use to diagnose problems safely.
Recommended Tools
If you’re confident carrying out basic checks, these tools can help identify electrical faults safely:
- Socket tester – quickly shows if the socket is wired correctly and safe to use
- Multimeter – helps check voltage, continuity, and identify faults
- Voltage tester pen – detects live wires instantly without contact
- Spare fuse kit – allows you to safely replace blown fuses in plugs when appliances stop working
For a full list of tools you can use, see our guide on best electrical tools for homeowners.
Using these tools can help you identify the problem in minutes and avoid unnecessary call-out costs.
Many homeowners use a simple socket tester first before deciding whether an electrician is needed.
These tools are widely available online and can be useful for basic fault finding in the home.
When to Call an Electrician
Some socket faults require circuit testing.
- Multiple sockets stop working
- Socket shows signs of heat or damage
- Power is intermittent
- You suspect a ring circuit fault
