Hiring Licensed Electrical Workers
Hiring Licensed Electrical Workers for
your Safety
Electrical work, whether at home or the office, should be carried out or supervised by a Licensed Electrical Worker (LEW). This includes the:
- Installation, repair or modification of electrical wiring;
- Addition, extension or replacement of electrical power points like socket-outlets, switches or lighting points; and
- Repair or replacement of consumer control units or circuit breakers.
Electrical work carried out by unlicensed electrical workers may pose safety risks and cause damage to property or injury to person.
Classes of Licensed Electrical Workers (LEWs)
There are 3 classes of LEWs. They are:
- Licensed Electricians
- Licensed Electrical Technicians
- Licensed Electrical Engineers
The class of LEWs to engage will depend on the scale of the electrical installation. For example, electrical work in a HDB flat will require the services of an electrician, while larger electrical installations like a food court will require the services of an electrical technician or even an electrical engineer.
Classes of LEWs | Scale of Electrical Installations |

All LEWs are issued with a card. This card includes the licensed worker’s photograph and it shows his name, identity card number and licence number.
1) Electrician's Licence

2) Electrical Technician's Licence
3) Electrical Engineer's Licence
Do
verify the LEW’s card before commencing electrical work at your home or
office.
