Domestic Electrical Installer (Part P 2013) - Full Scope

The following training and assessment packages are certificated by Logic Certification Ltd to industry led standards

Title Content type
Code: DEI
Expiry: 5 years
Guided Learning Hours: 5 days

The Domestic Electrical Installer (DEI) Training and Assessment package covers electrical work as outlined in the Part P Building Regulation (April 2013) and BS7671:2008 (2011) 17th Edition Wiring Regulations.

The DEI course is for operatives who carry out work on domestic electrical installations as a secondary task to their main role or who wish to offer full electrical installations in domestic properties as a stand-alone task.

NB:  From the 6th April 2013 the qualification entry requirements for companies or businesses wishing to join a Part P Competent Person Scheme (CPS) changed. The relevant change is for the designated qualifying 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 both the QS and installer. The QS must hold as minimum the "Level 3 NVQ Certificate in Installing, Testing and Ensuring Compliance of Electrical Installation Work in Dwellings" or equivalent. For larger businesses, the Part P 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. For operatives who do not hold the Level 3 NVQ or equivalent detailed above there is still an entry route that will require a more in depth on site assessment by the CPS, please speak to your prefered CPS for their entry requirements. You will be required to hold as a minimum the QCF qualification BS7671:2008 17th Edition Wiring Regulations.

Please see the following press release from the EAS technical committee who are responsible for the CPS requirements. A full list of Competent Person Schemes can be found at: website.
