When an existing socket may suit replacement

Work out whether the likely problem is the socket, a plugged-in item or a wider electrical fault before arranging a swap.

A residual current device (RCD) cuts power when it detects certain electrical leakage. An RCBO combines that protection with a circuit breaker for one circuit. Stop using the point if it buzzes, gives a shock or shows unusual fumes; crackling, tingling or a flash also mean stop. If there is no heat, damage, burning smell, water or tripping, check the socket’s normal switch and whether nearby sockets still work. Check only the appliance controls described by its manufacturer. Do not open the socket or try a wet, damaged or overheating item in another outlet. If protection has tripped, use the RCD or RCBO fault guide rather than repeatedly resetting it.

Safe checks before assuming the socket has failed

  • Note whether one socket, several nearby sockets or the whole circuit has stopped working, and whether the problem follows one plugged-in item.
  • Use only normal switches and manufacturer controls. Leave covers in place and do not use a plug-in tester as proof that a socket is safe.
  • A safe exterior photo is optional. If there is any warning sign named above, stop using the point and describe it instead of approaching for a photo.

When replacement is the right repair

  • Replacement may be suitable when the accessory is worn, cracked, loose or unreliable and the existing box, cable and circuit conditions are sound.
  • The electrician should isolate and prove dead, inspect the point, fit the correct accessory and complete the checks that apply before handover.
  • If the symptom follows an appliance, affects several points or involves tripping, fault finding may be more useful than replacing sockets one by one.
