If your Earth Leakage Circuit Breaker (ELCB) or Residual Current Circuit Breaker (RCCB) is not working, please engage a Licensed Electrical Worker (LEW) to install a new one. The installation cost of the RCCB for HDB flats is estimated to be about $500. If re-wiring works are required, the cost will depend on the scope of works involved to replace the existing wiring in the house. HDB will be writing to the homeowners of 3-room and larger HDB flat types, completed in and before 1985 without an RCCB, to share more information on the assistance programme for the installation of RCCB.

The RCCB installation cost for private homes is estimated to be about $600. If re-wiring works are required, the cost will depend on the scope of works involved to replace the existing wiring in the house. Homeowners are advised to get quotations from a few LEWs via here before deciding to engage one.
