If a double socket is not working, it may indicate a wiring issue, a tripped circuit, or a fault within the socket itself. This guide explains the most common causes and what checks you can safely carry out.
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 a Double Socket Is Not Working
- Loose or damaged wiring inside the socket
- Tripped circuit breaker or RCD
- Fault within the socket outlet
- Wiring fault on the circuit
- Burnt or damaged connections
Safe Checks You Can Carry Out
- 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.
- Check if other sockets are working
- Reset the circuit breaker or RCD
- Try another appliance in the socket
- Inspect for visible damage or burning
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
- Insulated screwdriver set – useful for safely tightening loose connections on sockets, switches, and plugs
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
- The socket remains dead after resetting the breaker
- Other sockets are also not working
- There are signs of burning or overheating
