Why faulty sockets matter
Plug sockets are used every day, so wear and damage are common. A loose, cracked or scorched socket is more than an inconvenience: poor connections can overheat and cause a fire, and damaged faceplates can expose live parts. With most households running more devices than ever, sockets in good condition help prevent overheating and reduce fire risk.
Warning signs include scorch marks or discolouration, a burning smell, buzzing or crackling, plugs that feel loose or fall out, a socket or plug that gets warm, and sockets that only work some of the time. If you notice any of these, stop using the socket and get it checked.
How repair and replacement work
The process usually starts with an inspection of the problem socket and the circuit it is on. The electrician will isolate the circuit, check the wiring condition and connections, test for faults and recommend whether to repair or replace. New sockets are installed to BS 7671:2018+A4:2026, the current IET Wiring Regulations, with options such as USB charging sockets, smart sockets or weatherproof sockets for outdoor use. Every installation is tested before handover.
RCD protection, Part P and certificates
BS 7671 requires new socket-outlets rated up to 32 A, and sockets used for equipment outdoors, to have 30 mA RCD protection. In England, replacing a socket like for like, or adding a socket to an existing circuit outside a bathroom, is not usually notifiable under Part P, and you should receive a Minor Electrical Installation Works Certificate (MEIWC). A new circuit, or new sockets in the zones around a bath or shower, is notifiable and comes with an Electrical Installation Certificate (EIC).
Combining socket work with bigger projects
Many homeowners combine socket work with consumer unit upgrades or add home surge protection to protect appliances.
