You should hire a certified electrician to do any electrical work required to install the charger. You should work with your strata manager or building manager to manage the installation.
In many cases it is possible that only a small amount of electrical work will be required to accommodate Level 1 charging. Installing Level 2 charging, however, may be more involved. Your electrician will be able to let you know what needs to be done to complete the install.
Hire a certified electrician
A certified electrician will arrange the proper permits and electrical inspection, and will ensure that the installation is completed to code. Use contractors that are familiar with electric vehicle charging and have experience installing chargers in apartments and townhouses.
