Electrical work or gas service work should be carried out or supervised by a licensed worker.
For electrical work, this includes new wiring, rewiring, and extensions. Before electricity supply is turned on, these works have to be tested and certified safe for use by a licensed electrical worker of the appropriate class. Related works such as replacement of bulbs, installation of water heaters, electrical equipment or appliances do not require a licensed electrical worker unless wiring works are involved.
Gas service work involves piped gas installation or piped gas appliances. This may include new gas installation and replacement, addition and alteration to existing gas installations. Similarly, such works are to be tested and certified safe for use by a licensed gas service worker before the piped gas supply can be turned on.
If you need electrical or gas service work to be done at your premises, make sure the person you intend to hire for electrical work has a valid licence issued by EMA.
Before commencing any earthworks, contractors must engage a licensed cable detection worker to carry out cable detection work.
