How to escalate a BEST complaint

Forward the complaint number to your group so nobody has to search for it mid-outage.

Share on WhatsApp Facebook X

No toll-free/1912 number is published by BEST; complaints go to zonal landlines or ward fuse-control centres. On 2026-10-16 the WhatsApp number and the two customer-care numbers previously listed here (+91 7208836089, 022-24101517, 022-23771839) were found under Street Lighting Complaints on the complaints page, not general supply complaints, so they were removed. Tata Power also holds a parallel licence in the BEST area.

Complaint not fixed? How to escalate

Every distribution licensee in India must run a Consumer Grievance Redressal Forum, and every state has an Electricity Ombudsman above it. Work up the ladder; keep your complaint number from step one.

If the supply was out longer than your state allows, the discom may owe you compensation. What you can claim, and how.
