Sarawak Energy’s utility arm, Syarikat SESCO Berhad (SESCO), is implementing the requirements set by the Inland Revenue Board of Malaysia (LHDN) on electronic invoicing (e-Invoice) for electricity and related bills starting 1 January 2026.

To ensure a smooth transition and compliance with these requirements, all electricity account holders are advised to update their personal or business information promptly. This will enable the accurate issuance of e-Invoices and prevent any potential billing interruptions.

SESCO has begun notifying customers through official letters outlining the required information and steps to complete the update process. Customers may conveniently update their details via the SEB Cares mobile application or web portal under “Subscription of Services – e-Invoice Registration” at
https://sebcares.sarawakenergy.com/SEBCares/EInvoiceRegistration.

Customers who prefer in-person assistance, or business entities with multiple contract accounts, may visit the nearest Sarawak Energy Customer Service Counter. Assistance is also available via email at customercare@sarawakenergy.com.

To facilitate the e-Invoice implementation, customers are required to provide complete and accurate information when updating their accounts.

Required details for individual accounts include the individual’s full name; identification number (I.C. number) for Malaysians or passport number and passport expiry date for non-Malaysians; Tax Identification Number (TIN); email address; and mobile number.

For business accounts, customers are required to provide the registered business name; Business Registration Number (BRN); Tax Identification Number (TIN); email address; and mobile number. Customers are also requested to provide supporting documents for verification to support the accuracy and completion of the update process.

This initiative aims to enhance billing efficiency and accuracy while supporting the Government’s nationwide digital compliance agenda. Customers who update their details will benefit from timely and accurate delivery of validated invoices, improved transparency and traceability of billing records, and readiness for future tax reporting and audit processes.

Customers who do not update their details may experience delays or disruptions in invoice delivery or billing accuracy.
