All cooktops, regardless of type, will need to be installed by a licensed electrician. That said, there are still things you can do to make sure the installation goes as smoothly as possible.
Before making a purchasing decision you should always make sure you have measured the installation space accurately. The cooktop will need to fit into an existing opening or cut-out in your kitchen cabinet or bench, so accurate measurements will ensure you buy an appropriately sized cooktop for the space. If there is not already a cut out space or existing opening, then you will need to have bench or cabinet work done beforehand.
Depending on what sort of connections are already in place, some professional upgrading may also be required. Booking an assessment in advance will help determine what is needed. At The Good Guys we offer cooktop installation as part of our Home Services. This can include installation, demonstration, and clean-up depending on the service selected.
