Socket & Plug Installation in Westminster

About socket & plug installation in Westminster

Adding or relocating a power socket involves running a new spur or radial circuit from an existing circuit or consumer unit, mounting the back box, and connecting to the ring main or radial. Whether you need extra sockets in a kitchen, USB charging points in a bedroom, or a weatherproof outdoor socket for the garden, the work must be carried out safely and to current wiring standards. A qualified electrician ensures the circuit can handle the additional load and that the installation meets BS 7671.

Adding a new socket circuit or extending an existing one is notifiable electrical work under Part P of the Building Regulations when it involves work in kitchens, bathrooms, or outdoors. Even in other rooms, electrical work must comply with BS 7671. Overloading circuits with extension leads and adapters is a leading cause of domestic electrical fires in the UK — properly installed sockets eliminate this risk.
