In the UK, it is not illegal to perform simple electrical work yourself, such as replacing light switches or sockets on a like-for-like basis. However, major works - such as installing a new circuit, rewiring a property, or adding circuits in kitchens and bathrooms - fall under Part P of the Building Regulations and must legally be certified by a registered competent person or notified to Building Control.
Always check that the electrician is registered with a government-approved scheme such as the NICEIC. This guarantees they undergo regular audits, carry sufficient public liability insurance, and are authorised to self-certify their work under Part P. Additionally, look for direct employment rather than sub-contractors.
Part P is the section of the Building Regulations in England and Wales that covers electrical safety in dwellings. A Part P certificate proves that your electrical installation is compliant and safe. You will require this certificate when selling or leasing your home, or when resolving insurance claims.
