Overview

All electrical work in dwelling must be carried out in line with Part P of the Building Regulations. From 6 April 2014 a person who is registered with a third party certification scheme for electrical installations in dwellings will be able to check domestic electrical work that is undertaken by others and certify that it is compliant with the building regulations.

Another way of demonstrating that electrical work is compliant with Part P is either:

• having the work checked and certified by a local authority or a private sector approved inspector
• self-certification by an installer who carried out the work, if they are a member of one of the electrical installations competent person self-certification scheme. - to find an electrician that is a member of these schemes you can go to their register.
