Course overview


The Domestic Electrical Installer course is a practical course designed for installers who carry out some electrical work, mainly as a secondary role. This could be a gas installer whom wants to wire in a boiler or a kitchen fitter that wants to install a new ring main. To be able to join a competent persons scheme such as the JIB or NIC it is necessary to have the DEI Part P, 18th Edition Wiring Regulations, plus suitable experience. This will then enable you to notify works to the Local Authority Building Control. If you are a tradesperson that requires electrical work to be carried out as part of your job such as wiring a boiler, shower or cooker then you may currently have to sub this work out to other tradesmen costing time and money on the job for you. With the DEI and 18th Edition Regulations qualifications you will gain the skills and knowledge so that you can safely complete these tasks yourself.
