Longmont Utilities: Pay Bill, Login & Phone 2026
City of Longmont utilities • Colorado customer guide
If you need to pay a City of Longmont utilities bill, sign in to the new utility portal, start or stop service, report an electric outage or understand a high bill, start with the task-specific information below.
Longmont’s combined City utility bill can include electricity, water, sewer, storm drainage and solid-waste service. One important exception is NextLight internet, which is billed separately from the City’s regular utility account.
Longmont Utility Billing Quick Answers
Longmont’s former secure utility-billing page now directs customers to MyUtilityAccount.longmontcolorado.gov and tells existing users to re-register.
The City’s migration notice says customers who had recurring credit-card or bank-draft payments must set those payments up again in the new system.
Do not use the regular City utility-billing account to assume a NextLight internet balance has been paid. NextLight has separate billing and support.
What Is Included on a City of Longmont Utility Bill?
Longmont’s City utility account is broader than a typical water-only municipal bill. Depending on the property and services subscribed to, the account can contain several separate City services.
Community-owned electric service with tiered residential rates and separate summer pricing.
Monthly meter charge plus tiered water-consumption charges. Rates differ inside and outside City limits.
Metered customers pay a monthly service charge plus a volume-based charge.
Residential customers pay the current monthly storm-drainage user fee.
Residential waste charges depend on cart size, pickup frequency and whether curbside compost is included.
NextLight broadband is operated by Longmont Power & Communications but is billed separately from other City utility services.
How to Pay a Longmont Utilities Bill
The City currently lists six general payment methods: online payment, automatic recurring payment, in-person payment, mail, direct payment through your bank and phone payment.
Use the City’s new utility account system to register, pay bills and manage autopay.
The City’s Utility Bill page also identifies a one-time payment route for customers who do not want to save billing information month to month.
Enroll through the new online account. Longmont’s EFT program does not add a City service charge.
Call Utility Billing from 8:00 a.m.-5:00 p.m. weekdays to pay by credit or debit card.
Pay at the Longmont Civic Center during current business hours.
Mail a check with the monthly bill stub. Leave enough time for delivery and posting.
After opening the official Utility Bill page
- Choose online account registration, one-time payment or another listed payment method.
- If you want account history or autopay, use the new MyUtilityAccount portal.
- Keep your City utility account number from the monthly statement nearby.
- Confirm the service address and amount before submitting payment.
- Keep your transaction confirmation until the account balance reflects the payment.
Automatic Payment by EFT
Longmont’s automatic-payment program can withdraw the monthly amount directly from a checking account. The City says the bill is sent at least 10 days before the scheduled deduction so you have time to review it.
The payment is then deducted on the due date. The City says its EFT program does not add fees or service charges.
Official Longmont Automatic Bill Payment InstructionsAfter opening the automatic-payment page
- Open or create your account at MyUtilityAccount.longmontcolorado.gov.
- Use your utility account number to complete account setup.
- Open the billing and payment area in the portal.
- Choose the autopay option and enter the required payment information.
- Review the next bill to confirm automatic payment is active before relying on it.
City of Longmont Utilities Login: What Changed?
Longmont has moved utility customers to a new online payment website. This matters if you have an old bookmark: the previous secure portal now displays a notice directing customers to MyUtilityAccount.longmontcolorado.gov.
The City’s migration notice also tells previous users to re-register. Customers who used recurring card or bank-draft payments are instructed to set those payments up again in the new system.
Open MyUtilityAccount.longmontcolorado.govAfter opening the new Longmont utility portal
- If you have not used the new system, use its account-registration route rather than assuming old credentials will work.
- Have the account number from a recent City of Longmont utility statement available.
- Residential customers should make sure the Social Security information required by Utility Billing for account security is already on file.
- After registration, verify the service address and account balance.
- If you previously had autopay, confirm that the new recurring payment has been recreated successfully.
What Online Account Access Can Show
- Current amount owed to the City
- Previous payments
- Electric usage history
- Water usage history
- Online bill payment
- Paperless billing and account-management options
Start, Stop or Transfer Longmont Utility Service
Longmont gives residential customers both phone and online options, but the processing time differs. The City asks for at least two business days when requesting a change by phone and three business days for an online request.
If you own or are purchasing the home, Longmont says you can connect service by phone or online without a residential deposit.
Residential customers who do not own or purchase the home must normally pay a $100 electric deposit unless an acceptable prior-utility letter of credit is used.
Plan ahead so the City can read electric and water meters and close the previous customer’s account correctly.
Information Longmont May Request
For residential setup, the City says it may ask for identity and contact information including driver-license and Social Security details, employment information, phone numbers, a nearest relative and a local reference.
After opening the service-change page
- Choose whether you are connecting, transferring or disconnecting service.
- If using the online route, allow at least three business days.
- If calling Utility Billing, allow at least two business days.
- Prepare identity, contact and property information requested by the City.
- If you rent, confirm whether the $100 electric deposit or an acceptable letter of credit applies.
Selling a Home
Longmont says the property owner—not the realtor or title company—must request the utility disconnection. The City asks for at least 24 hours to complete a seller’s disconnect request.
In many sales, the final utility bill is sent to the title company. The title company can request an estimate before closing and escrow that amount so the transaction can close with the utility balance accounted for.
NextLight Is Separate
Starting or stopping regular City utilities does not automatically manage NextLight broadband. For NextLight service, call 303-774-4494. Longmont lists weekday NextLight customer-service hours separately from Utility Billing.
Past-Due Longmont Utility Bill or Disconnect Notice
Longmont mails utility bills approximately every 30 days. Your actual due date is printed on the bill. If you cannot pay by that date, the City instructs customers to contact Utility Billing rather than waiting for service interruption.
Longmont Utility Rates in 2026
Longmont’s combined utility bill can change for several reasons, so looking at only one rate can be misleading. Electricity is tiered, water is tiered by usage and location, and sewer, storm drainage and waste have separate charges.
2026 Residential Electric Rates
As of September 12, 2026, Longmont’s summer electric rates remain in effect through September 30. Standard residential electric service also carries a $17.50 monthly customer charge.
| Usage tier | Non-summer | Summer |
|---|---|---|
| First 750 kWh | 10.57¢ per kWh | 11.64¢ per kWh |
| 751-1,500 kWh | 12.45¢ per kWh | 13.73¢ per kWh |
| Over 1,500 kWh | 16.18¢ per kWh | 17.83¢ per kWh |
| Monthly customer charge | $17.50 | $17.50 |
After opening the electric-rate page
- Confirm whether your bill falls in the summer or non-summer period.
- Compare your total kWh with the three residential tiers.
- Include the $17.50 customer charge when reviewing the electric portion of the bill.
- If you are on the Residential Demand or self-generation rate instead, use that separate rate table.
2026 Water, Sewer and Stormwater Snapshot
| Charge | Current amount | Useful detail |
|---|---|---|
| 5/8-inch water meter service charge | $11.91 / month | Inside City limits; the City describes 5/8 inch as the typical residential meter. |
| Water: first 5,000 gallons | $4.84 per 1,000 gallons | Inside City limits; higher usage moves into progressively higher tiers. |
| Wastewater service charge | $11.50 / month | Metered accounts also pay a $7.82 volume charge per 1,000 gallons. |
| Residential storm drainage | $18.85 / month | Current City residential storm-drainage user fee. |
After opening the water and sewer rate page
- Confirm whether the property is inside or outside Longmont City limits.
- Find your water-meter size on the bill or account record.
- Match monthly water consumption to the correct tier.
- Review wastewater and storm-drainage charges separately rather than treating the bill as water only.
Current Residential Trash Options
Longmont uses a pay-as-you-throw structure. Current base trash-only prices are $7.10 per month for a small 48-gallon cart collected every other week, $14.10 for a medium 48-gallon weekly cart and $26.30 for a large 96-gallon weekly cart.
Recycling is included with residential trash service. Curbside composting is currently $9.90 per month, and Longmont also lists a $2.96 monthly Waste Management Fee.
Longmont High Bill, Budget Billing and Payment Assistance
A high bill does not always mean the same thing. Check electric and water usage first, then look for service-level changes such as a larger trash cart, seasonal electric pricing or heavy outdoor water use.
Budget Billing
Longmont’s Budget Billing Program spreads utility costs into equal monthly amounts based on the average of approximately one year of charges.
The City says you must have lived at the current address for at least six months and have no past-due balance to enroll. Call Utility Billing at 303-651-8664 for enrollment.
COPE and the OUR Center
Longmont’s COPE — Citizens’ Option to Provide Energy program helps residents with past-due utility bills after other resources have been exhausted. The City partners with the OUR Center, which screens assistance requests.
For assistance, the City also directs customers to the OUR Center at 303-772-5529.
Official Longmont Utility Assistance ResourcesAfter opening the assistance page
- Review the agencies and programs listed for Boulder County residents.
- Match the program to your situation rather than sending the same documents everywhere.
- Contact the program directly to confirm current eligibility and funding.
- Continue communicating with Utility Billing if your City account is already past due.
LEAP for Eligible All-Electric Homes
Longmont’s current Utility Bill FAQ says customers with an all-electric home and no gas heat may apply for Colorado’s LEAP program during its normal November-April season. The statewide LEAP number listed by the City is 866-432-8435.
