Online Bill Pay and 2025–2026 Portal Changes
Start from the City of Seneca site
Open Seneca Light & Water and use the official Utilities Payment link. This is safer than using saved old payment bookmarks.
Use GovernmentWindow for current online pay
The online payment page states that GovernmentWindow is now the utility payment processor for Seneca, SC Utilities.
Create a login if you need stored methods
The portal lets customers create a login for recurring bills and commonly used payment methods, or use a Pay Now style one-time payment route.
Re-enter autopay if needed
The online processor notice says autopayment information did not transfer from the previous system. Customers using autopay should create a new account and re-enter payment details.
Call if disconnected
GovernmentWindow says if you make a payment on a disconnected account, call SL&W at 864-885-2723 so the account can be updated right away.
2026 Online Payment Fees: Card and eCheck
Credit/debit card
Seneca Light & Water lists a convenience fee of 3% or $2 minimum on credit/debit card payments starting January 1, 2026.
eCheck
The listed eCheck fee is $2.50 starting January 1, 2026.

This is the most important section if your bill is late. The official FAQ is clear that online payment is not the safest standalone option for delinquent or disconnected accounts.
| Account status | Official rule | Best next step |
|---|---|---|
| Past due | Partial payments on past-due balances do not guarantee service will not be disconnected. | Call 864-885-2723 during business hours and confirm what amount is required. |
| Delinquent bill paid online | If you choose to pay a delinquent bill online, allow 48 hours for processing. | Do not assume the payment prevents disconnection unless the office confirms. |
| Disconnected for non-payment | Payment in full of past due balances plus a non-payment fee is required. | Call the office to process payment/reconnect steps rather than relying only on online pay. |
| Non-payment fee | Seneca Light & Water lists the non-payment fee as $25.00. | Budget for this fee if service has been disconnected or the account is on disconnect status. |
| Disconnected bill paid online | If you pay a disconnected bill online, allow 48 hours for processing. | Call 864-885-2723 so the office can update the account right away. |

Report a Power Outage, Water Leak or Sewer Backup

High Seneca Light & Water Bill Checklist
Seneca utility bills may combine electric, water and sewer charges. Before comparing with a neighbor, check which services are included and what changed in the home.
Compare full utility mix
SL&W notes its utilities are usually included on the same bill, so comparing to a neighbor with separate bills can mislead you.
Heating and cooling
Heating and cooling often drive energy use. Thermostat settings, insulation and appliance efficiency can change the bill.
Water or sewer spike
Check toilets, faucets, irrigation, outside spigots, underground leaks and any water-heavy activity before assuming the bill is wrong.
Before calling, gather this
- Current bill and previous 2–4 bills.
- Electric kWh usage, water usage and sewer charges if shown separately.
- Recent weather, thermostat changes or appliance changes.
- Any water leak, toilet repair, irrigation or plumbing work.
- Photos, meter readings, repair receipts or electrician/plumber notes.
- Whether the bill is current, past due or on disconnect status.
Electric Meter Basics for Seneca Customers
Read left to right
For digital electric meters, the official FAQ says the display is read like a car odometer, from left to right.
kWh meaning
A kilowatt-hour is 1,000 watts used for one hour. Electric consumption is billed based on kWh usage.
Usage math
Subtract the previous meter reading from the current reading to estimate monthly electric usage.
