What Is Submetering? How Your Apartment Light Bill Works
Sub-metered apartment? Learn exactly what submetering means, how it affects your light bill, and what to do if the numbers don't add up.
If your light bill comes from your landlord or a company you never signed up with, you’re in a submetered apartment, and that changes everything about how you pay for lights.
This isn’t a scam. It’s a legal billing setup that’s common in Texas apartments. But it can absolutely catch you off guard if nobody explained it to you upfront. Here’s exactly how it works, what the rules are, and what you can do if the numbers feel wrong.
What Submetering Actually Means
A sub-metered apartment has its own individual meter that tracks only your unit’s usage. The landlord or property management company pays one master bill to the light company for the whole building, then divides the cost among tenants based on what each unit’s submeter recorded.
That middle company billing you, the one with a name like NWP Services, Conservice, or ista North America, is called a submetering company. They handle the math and send your bill. You never set up an account with a light company directly. You pay through them, and they settle up with the actual light company on the back end.
Submetered electricity in apartments is different from what’s called RUBS, which stands for Ratio Utility Billing System. With RUBS, the building splits the total light bill by square footage or number of occupants. Nobody has an individual meter. You just get assigned a share. With true submetering, your meter reads your actual usage, so you pay for what you used, not a guess.
Why Landlords Use Submetering
Simple answer: it saves them money and shifts cost to tenants.
When a landlord pays one master bill and bundles lights into rent, there’s no reason for tenants to conserve. Submetering makes each unit financially responsible for its own usage. That’s not automatically bad for you. If you’re careful with lights and AC, you may pay less than a neighbor in a bigger unit running the heat all day.
Landlords also use submetering because it’s cheaper to install one master meter on a building than to set up individual accounts for 200 units. The light company runs one line. The submetering company handles the rest.
What Shows Up on a Sub-Metered Apartment Light Bill
Your apartment electric billing statement from a submetering company will usually include a few line items beyond just usage:
- Your actual usage charge. Based on your submeter reading, multiplied by a per-kWh rate.
- A billing or administrative fee. Usually $3 to $10 per month. This is the submetering company’s cut.
- Possible pass-through charges. Things like transmission fees or taxes that the landlord’s master bill included.
In Texas, submetering companies are regulated by the Public Utility Commission of Texas (PUC). They cannot charge you more per kilowatt-hour than the landlord paid the light company. That’s the law. If your rate per kWh is higher than what your landlord’s light company charges, that’s a violation you can report.
How to Check If You’re Being Overcharged
This is straightforward. You have the right to ask your landlord for a copy of the master light bill. Texas law requires them to provide it if you ask in writing.
Once you have it, find the total cost per kWh the landlord paid. Then compare it to the rate on your submeter bill. Your rate should be equal to or lower than the landlord’s rate. If it’s higher, you’re being overcharged.
You can file a complaint with the PUC at puc.texas.gov or call 1-888-782-8477. Keep copies of your bills before you do.
Also check the meter read dates on your bill. If the billing period is 45 days but you’re being charged for 30, the math is off. Meter reading errors happen, and you’re allowed to request a reread.
What Submetering Means for No Deposit Lights
If you’re in a sub-metered apartment, you did not sign up with a light company directly. That means your credit was never pulled for lights. The landlord’s credit is what got the master account approved, not yours.
That’s actually good news for credit-challenged renters. Moving into a submetered building means you sidestep the deposit requirement entirely on lights. The tradeoff is less control. You can’t switch light companies to get a better rate. You pay whatever the building’s contract rate is.
If you’re moving and trying to avoid a big deposit, a sub-metered apartment is one real option. The other options are pay-as-you-go lights through a prepaid light company, or finding a light company that offers no deposit lights based on factors other than credit score.
When the Lights Got Cut Off in a Submetered Building
This is where things get complicated fast. If you fall behind on your submeter bill and your lights got cut off, you’re dealing with the landlord or the submetering company, not a light company you have a direct account with.
In Texas, a landlord cannot cut your lights off as a way to force you out. That’s illegal self-help eviction. If your lights got cut off and you’re current on rent, contact Texas Legal Services at 1-888-988-9996. They handle exactly this situation.
If you genuinely owe a past-due balance on the submeter account, you’ll need to pay that balance to the submetering company directly to get the lights back on. Get the exact amount in writing before you pay anything.
Bottom Line
Submetering is legal, common in Texas apartments, and not automatically a bad deal. You pay for what you use, and you skip the deposit fight with a light company. But you also have less control over your rate and fewer options when things go wrong. Know the rules, ask for the master bill if anything looks off, and keep your submeter statements every month.
