Quick answer
From 1 September through 31 December 2026, TNB says domestic customers using 800 kWh or less a month are exempt from the Automatic Fuel Adjustment (AFA), the RM10 Retail Charge and 8% service tax. For September, eligible charges are calculated pro rata and credited to the October 2026 bill.Check for “BILL ADJUSTMENT (SEP 2026)” and “SERVICE TAX ADJUSTMENT (8%) (SEP 2026)”. This is TNB’s published billing instruction; it does not establish identical treatment for every electricity provider, a fixed ringgit saving or a reduction to the base tariff.Who may be affected
TNB says its domestic customers with monthly electricity use of 800 kWh or less are covered from 1 September through 31 December 2026. This raises the earlier 600 kWh threshold. “800 kWh and below” includes an exact 800 kWh reading.The 2 October TNB notice explains how the September benefit appears on an October bill. The notice is specific to TNB’s implementation; do not assume it sets the bill treatment for other providers, account types or locations.What the protection covers
TNB names three exemptions for eligible domestic customers:| Bill item | TNB’s notice |
|---|---|
| Automatic Fuel Adjustment (AFA) | Exempt for monthly use of 800 kWh or less during the stated period. |
| Retail Charge | The RM10 charge is exempt. |

How to check the relevant bill details
Use this checklist for the October 2026 TNB bill:- Check the billing period and monthly electricity use. TNB says the threshold is 800 kWh or less.
- Look for “BILL ADJUSTMENT (SEP 2026)” and “SERVICE TAX ADJUSTMENT (8%) (SEP 2026)”. These are the two labels TNB published for the September credit.
- TNB says the September adjustments are pro-rated. The notice does not publish a formula for estimating an individual customer’s credit, so do not treat a general estimate as a guaranteed saving.
- If the credit or usage figure is unclear, compare the itemised bill with TNB’s official billing information or contact TNB through its customer channels.
- For November and December usage, check the latest TNB notice before relying on this article; the stated protection period ends on 31 December 2026.

It explains TNB’s treatment, including the pro-rated September credit; it does not confirm the same implementation for every provider or every account arrangement.The stated protection period ends on 31 December 2026. Any later extension, expiry rule or threshold change needs a new official notice.Frequently asked questions
