Please note the login method update: starting from September, CLP will adopt "passwordless login" to replace the old login methods using username and password. If you continue to log in using email or mobile number, please update your email address or mobile phone number to receive a one-time password (OTP) for logins.

If you use "iAM Smart Login" or social media login, you can continue using these methods.

When selecting the account type during login in the CLP One App, opting for "Residential" tab enables you to access all electricity accounts linked to your name for all residential properties. For commercial accounts, please select the "Business" tab on the Login page to login or create commercial electricity accounts.

If the system indicates incomplete identity verification documents or if addresses are not fully visible under "My Services," we recommend following the system's instructions to complete the identity verification process. This will facilitate the full display of your account details.

Can I still use my old login method for my CLP One Profile?

I am a shop owner and also the registered electricity account holder for the residential property. After logging into the CLP One Account, why can I only view the address of the residential property and not the commercial shop address?

After I log in, why are some of my electricity account addresses not fully displayed? How can I view the complete address?
