What the symptom can tell you
A non-working socket may involve the outlet, an appliance, a circuit or a protective device. An electrician needs to establish the cause before deciding what to replace. Do not remove the faceplate or touch wiring, and do not treat a dead outlet as isolated.
If there is scorching, unusual heat, sparking or a burning smell, keep people away from the affected fitting and stop using it. Avoid touching damaged equipment to investigate. A professional can assess the socket and the wider circuit rather than simply replacing the visible part.
The plug is loose or falls out
A connection that no longer holds a plug securely is a different observation from a socket with no apparent power, but neither should be dismissed because the appliance sometimes works. Stop using the affected connection and describe the behaviour to a qualified professional.
Do not wedge the plug in place, bend its pins or test it repeatedly in other positions. Loose plugs are included in the CPSC’s general warning-sign guidance; that reference is not a Portuguese installation standard.

When access is behind furniture or fitted equipment
Explain whether the fitting is visible, behind a freestanding item or concealed by a fitted appliance. Ask who will arrange appropriate access before the visit; the electrician may need information from the person responsible for the appliance or cabinetry.
Do not handle a damaged plug, pull out heavy equipment or dismantle a kitchen to inspect the connection. A description of the access constraint is more useful than taking risks to obtain a photograph.
A repair and an extra socket are separate decisions
If the failed point has also exposed a shortage of convenient sockets, list that as a second request. First explain the fault; then describe where equipment is used and which new positions would help. Do not treat an additional socket as a substitute for investigating the existing concern.
Ask the proposal to distinguish the repair, any circuit assessment and the new layout. Agree finishes and access responsibilities alongside the visible accessories.
Questions for your project
Is a socket that appears dead safe to open?
No. Lack of apparent power does not establish isolation. Do not remove the faceplate or touch wiring; arrange professional assessment.
Should I hold a loose plug in position if it still works?
No. Stop using that connection and have it assessed. Do not use improvised supports or alter the plug to keep it in place.
Can I ask for another socket at the same time as the repair?
You can describe both requests, but they need distinct scope decisions. The existing fault should not be ignored, and any new point needs assessment of its intended use and installation.
Useful details to record
- Where the socket is and when you first noticed the issue
- Whether other outlets or lights are affected
- Recent work nearby or visible water damage, if already known
