Air-Conditioner Installation Works
HDB blocks completed on/ after 1 January 1994 or have undergone the Main Upgrading Programme (MUP)/ Home Improvement Programme (HIP) are provided with higher electrical loading of 40amps main switch.
If you are unsure of your block's electrical loading, you can use the Electrical Loading of Your HDB Block e-Service to check. You need not apply for a permit from HDB to install an air-conditioner or higher capacity electrical equipment/ appliances if your flat is provided with higher electrical loading.
Alternatively, you can call our Branch Service Line at 1800-225-5432 (toll-free) to enquire.
