An electricians registration and certificate of completion and testing scheme has been set up, they say, but most of the public do not know about the protection it gives.
Around 110 electricians are registered with the Planning Department.
Any work involving more than adding a few extra plug sockets should require a certificate.
People who are having electrical work done on their properties should ask to see whether the workmen are registered with the department, and should ask for a certificate of completion and inspection when the work is done, say Planning.
