Domestic Electrical Installer Part P

The Domestic Electrical Installer (DEI2022) Training and Assessment package covers electrical work as outlined in the Building Regulations and complies with BS7671:2018 Amendment 2 (2022).

This course is designed for installers working within the electrical or related industries to enhance their electrical skills and knowledge along with the relevant Health and Safety aspects of working on, or with, electrical installations and equipment.

This course has not been designed to take a non-qualified / non-trade related person and to make them into an electrician, but has been designed to give these persons a greater understanding of the health and safety requirements of working with electricity.

Companies, businesses and sole traders wishing to join a Part P Competent Person Scheme (CPS) must have a designated Qualified Supervisor (QS).  In a larger organisation the QS will be responsible for the competence and work of all installers carrying out electrical installations. Sole traders are regarded as both the QS and the installer.

The Qualified Supervisor must hold as minimum LCL Awards Level 3 Certificate in Installing, Testing and Ensuring Compliance of Electrical Installation Work in Dwellings

For larger businesses, the DEI qualification can still be used for operatives who are under the direction of the qualifying supervisor. Sole traders must comply with the qualification entry requirement detailed above.

Further information can be found in the scheme document from IET who are responsible for the CPS requirements.

A full list of Competent Person Schemes can be found at communities.gov website

The Domestic Electrical Installer course covers the underpinning knowledge and practical aspects of planning, installing, fault finding and commissioning of domestic electrical installations. The areas covered are as follows:

This can also be used for operatives who are undertaking electrical work that is not notifiable under Building Regulations

Centres should ensure that the candidates have the potential to achieve this course. Candidates must have the minimum levels of literacy and numeracy to complete the course and all assessments.
