General Information
Course Structure and Learning Outcomes
The Domestic Electrical Installer (DEI2026) Training and Assessment package covers electrical work as outlined in the Building Regulations Approved Document P and complies with BS7671:2018+A4:2026.
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 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 within dwellings.
Businesses and sole traders wishing to self-notify electrical work by joining a Part P Competent Person Scheme (CPS) must employ 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 installation work.
For larger businesses, the DEI course can still be used for operatives who are under the direction of the qualifying supervisor..
Further information on the competency requirements for QS 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
