Quick answer
There is no fixed number of months. TNB does not disconnect on a calendar count. The process runs in stages — an unpaid bill, then a formal disconnection notice, and only then does disconnection follow. A tenant whose account is more than one billing cycle overdue and who ignores the notices is the realistic risk point.
The confusion comes from older guides that quote a single month number. In practice the trigger is not the month count but the notice flow: TNB issues reminders and a written disconnection warning before a technician is sent. Pay as soon as the notice arrives, or contact TNB to arrange a payment plan, and the power stays on. The exact days between notice and disconnection are set in TNB's current supply terms and can change, so confirm the live timeline on the myTNB portal rather than trusting a stale forum figure.
How TNB's unpaid-bill process actually works
TNB follows a staged recovery process: unpaid bill, reminder notices, a formal disconnection notice, then physical disconnection and reconnection fees. There is no automatic month-2 or month-3 cutoff in the tariff itself.
The table sets out the stages. The days given are the typical flow a tenant sees on the myTNB app and bill — confirm the current intervals against your own notice, because TNB updates its supply terms.
| Stage | What happens | What the tenant sees | What to do |
|---|---|---|---|
| 1. Bill due | Monthly bill generated; payment due date printed on the bill | "Amount due" in myTNB app and SMS/email reminder | Pay before the due date |
| 2. Overdue reminder | First reminder issued after the due date passes | Reminder notice, sometimes a red banner in myTNB | Pay immediately or contact TNB for a payment arrangement |
| 3. Disconnection notice | Formal written notice warning that supply will be disconnected if the arrears are not cleared | A disconnection warning notice — this is the last clear signal before a technician visit | Pay the full arrears, or call TNB before the stated date |
| 4. Disconnection | A TNB technician disconnects supply at the meter | Power goes off; a disconnection notice is left at the premises | Pay arrears plus reconnection charges to restore supply |
| 5. Reconnection | Supply restored after payment and a reconnection fee | Power restored, usually within a set period after payment clears | Keep the payment receipt until power is back |
The takeaway: the disconnection notice (Stage 3) is the real countdown, not the month count. A tenant who acts at Stage 2 or 3 almost always avoids Stage 4. For the full utility picture — including who the account should be in — read the managing utility bills guide for tenants and landlords.
Whose name is the account in, and why it matters here
TNB chases the registered account holder — the person whose name is on the account — not necessarily the person living in the unit. If the account is still in the landlord's name, an unpaid tenant bill lands on the landlord, and the landlord cannot then disconnect supply themselves as a remedy.
This is the part most tenants miss. The disconnection timeline above applies to the account holder. In a rental there are two common situations:
- Account in the tenant's name (transferred via the TNB Change-of-Tenancy process): the tenant is the account holder, TNB chases the tenant, and the disconnection process runs against the tenant directly.
- Account still in the landlord's name: the tenant pays the landlord or pays the bill on the landlord's account. If the tenant stops paying, the arrears build against the landlord, and TNB's notices go to the landlord — not the tenant.
The SPEEDHOME-recommended setup is to transfer the TNB account to the tenant's name at move-in and record the opening meter reading on both sides. That puts the tenant in direct control of the disconnection timeline and removes the most common end-of-tenancy dispute. See the TNB Change of Tenancy explainer for the documents and deposit involved.
The SPEEDHOME angle — prevent the problem, do not manage the cutoff
On a managed SPEEDHOME tenancy the utility responsibility is set out in the standard tenancy agreement before move-in, so the "whose name, who pays" question is answered upfront rather than fought over when a disconnection notice arrives.
The rental security deposit is separate from the TNB deposit and from monthly electricity bills. If a tenant leaves with arrears on an account still in the landlord's name, any deposit deduction has to be tied to a proven, quantified shortfall — not an assumed holdback. And a landlord who is frustrated by an unpaid TNB bill cannot take matters into their own hands: a landlord cannot lawfully recover possession or pressure a tenant by disconnecting water or electricity under the Specific Relief Act 1950 s.7(2). The lawful route for an unpaid bill is the civil process, not self-help.
Zero Deposit is a managed rental-risk system, not a financial guarantee product. It replaces the upfront cash deposit; in the rare case of severe end-of-tenancy damage the recoverable amount can be limited. It does not cover electricity arrears — those sit with whoever holds the TNB account.

FAQ
Will TNB really cut my electricity after one unpaid month?
Not automatically on a fixed count. After the due date TNB issues reminders, then a formal disconnection notice. Disconnection follows the notice, not a calendar month. If you receive a disconnection notice, pay or contact TNB the same day — the notice is the real countdown.
Can my landlord cut the electricity if I have not paid the TNB bill?
No. A landlord cannot lawfully disconnect water or electricity to pressure a tenant. Under the Specific Relief Act 1950 s.7(2) a landlord cannot recover possession or coerce payment by disconnecting water or electricity. Only TNB, acting on its own account process against the account holder, may disconnect supply. See whether a landlord can cut electricity or water.
The TNB account is in my landlord's name and I am behind on paying — what happens?
TNB's notices and any disconnection action go to the account holder, which is your landlord. You will not see the disconnection notice directly. Ask the landlord for the current balance and pay it, because the power to your unit will still go off if the account is disconnected — and the landlord can pursue the arrears from you under the tenancy agreement.
How do I stop a disconnection once I have had the notice?
Pay the full arrears shown on the disconnection notice, or call TNB before the stated disconnection date to arrange a payment plan. Keep the payment receipt. If supply has already been cut, pay the arrears plus the reconnection charge, and supply is restored once payment clears.
Should I transfer the TNB account to my own name as a tenant?
In most cases yes — it puts the billing and the disconnection timeline in your hands and avoids end-of-tenancy disputes over whose arrears they were. The transfer is done through the myTNB portal or a Kedai Tenaga, and requires the account documents and a deposit based on estimated usage. The TNB Change of Tenancy guide walks through the steps.
