Is an electrical socket not working even though other parts of your home still have power?
The problem may affect one socket, several sockets in the same room or an entire socket circuit. Possible causes include a faulty socket, a loose connection, damaged wiring or a circuit breaker that has tripped.

Why Is an Electrical Socket Not Working?
A socket without power does not always mean that the socket itself is faulty. The appliance plug, socket terminals, circuit wiring and protective devices inside the DB box may also need to be checked.
Possible causes include:
- A tripped MCB or RCCB.
- A damaged or worn electrical socket.
- A loose cable connection behind the socket.
- Damaged or disconnected wiring on the socket circuit.
- A fault at one point affecting other sockets on the same circuit.
- A faulty appliance or plug.
- A loss of power affecting part of the property.
The actual cause should be identified before replacing the socket or any other electrical component.
Is the Socket Faulty or Is the Appliance the Problem?
If only one appliance does not operate, the fault may be with the appliance or its plug rather than the electrical socket.
You can try another appliance that is known to be working on the affected socket. The suspected appliance may also be tested on another working socket if it is safe to do so.
Stop immediately if the socket feels loose or hot, produces a burning smell, shows signs of overheating or makes an unusual sound.
Check Whether the MCB or RCCB Has Tripped
An MCB or RCCB inside the DB box may disconnect the supply when it detects an unsuitable electrical condition. When this happens, one circuit or several parts of the property may lose power.
You may observe the position of the switches without removing the internal cover of the DB box. If an MCB or RCCB trips again after being reset, do not continue resetting it because a fault may still be present on the circuit or connected equipment.
If the socket problem occurs together with repeated tripping, read our guide explaining why home electricity keeps tripping.
Why Are Several Sockets Not Working?
Several sockets may be connected to the same circuit. A loss of supply, a faulty connection or a problem at one point on the circuit can cause several sockets to stop working at the same time.
This does not necessarily mean that every affected socket is damaged. The circuit should be checked to locate the fault before replacing multiple sockets.

Can a Loose Wiring Connection Cause the Problem?
Yes. Electrical cables behind a socket must be secured correctly at their terminals. A loose connection can interrupt the power supply and, in some cases, produce heat, noise or signs of burning.
The condition of these connections cannot normally be confirmed by looking at the outside of the socket. Do not remove the socket faceplate or touch the internal wiring unless you are qualified to carry out the work safely.
If the socket feels warm or shows signs of overheating, read our guide about a hot electrical socket and the warning signs that should not be ignored.
What Can You Check Safely?
You can make a few basic observations without opening the socket or DB box:
- Make sure the switch on the socket is turned on.
- Try another appliance that is known to be working.
- Check whether other sockets in the same room are also affected.
- Observe whether an MCB or RCCB has tripped.
- Look for cracks, black marks or discolouration.
- Check for unusual heat or a burning smell.
- Notice when the problem occurs and which appliances are being used.
Do not insert tools or other objects into the socket openings to test for electricity. You should also avoid removing the faceplate or touching the cables behind it.
When Should You Contact an Electrical Contractor?
Arrange an inspection if the socket remains without power after another appliance has been tried, or when several sockets stop working at the same time.
The problem should also be checked without delay if you notice:
- A burning or melted-plastic smell.
- Black marks, melting or discolouration.
- A loose socket faceplate.
- Buzzing, hissing, crackling or sparks.
- An MCB or RCCB that continues to trip.
- A socket becoming hot while in use.
- A loss of power affecting part of the property.

Does the Socket or Wiring Need to Be Replaced?
Not every socket problem requires the wiring to be replaced. If the fault is limited to the socket or one connection, repairing or replacing the affected part may be sufficient.
Wiring work may be required if damaged cables, faulty connections at several points or an unsuitable circuit are found during the inspection. The necessary work should be based on the actual fault rather than the loss of power alone.
Frequently Asked Questions
Why is only one electrical socket not working?
The problem may involve the socket, its terminal connection, the cable or the appliance being used. The affected parts need to be checked before the cause can be confirmed.
Why are all the sockets in one room not working?
The sockets may be connected to the same circuit. A tripped circuit breaker or a fault at one point on the circuit may affect several sockets.
Can I replace an electrical socket myself?
It is not recommended if you do not have the necessary knowledge and qualifications. The cables behind a socket may remain energised and can present a risk of electric shock, arcing or further damage.
Does a socket without power mean the home wiring is damaged?
Not necessarily. The problem may be limited to the socket, one connection, a circuit breaker or an electrical appliance. The wiring should be inspected before reaching a conclusion.
Need Help with an Electrical Socket?
If one or several sockets are not working, avoid replacing components before identifying the actual cause. An inspection can determine whether the problem involves the socket, wiring, circuit or protective devices inside the DB box.
