How much are St. Charles utility rates in 2026?
St. Charles utility rates are set by the city, not a private utility: inside city limits, the City of St. Charles bills electric, water, and sewer together on one monthly bill, and Nicor Gas handles natural gas. Under Ordinance 2026-M-7, approved April 6, 2026, electric rates dropped 5% in June 2026 while water and sewer rates rise every June through 2029. The city’s own sample bill goes from $200.00 before the change to $234.67 in June 2026 and $298.31 by June 2029, which is a real budget line for anyone shopping in Chicago’s Western Suburbs.

If you are just starting to look at homes in St. Charles, Illinois, the listing will show taxes and maybe HOA dues, but not the utility bill. On r/ChicagoSuburbs, one of the first questions in a “thinking of moving to St. Charles” thread was what monthly utilities run, and the answers ranged from about $175 to $250 a month for a townhouse.
Those numbers came before the 2026 increases. Here is how St. Charles utility rates work now, what the city’s ordinance and rate schedule actually say, why the bills are climbing, and how to check a specific address before you write an offer.
St. Charles utility rates by the numbers
All of the figures below come from Ordinance 2026-M-7, which amended Title 13 of the St. Charles Municipal Code. The new rates apply starting with the first billing period after June 1, 2026, and each later step takes effect for bills issued after June 1 of that year.
Electric: a city-owned system with a 5% cut
St. Charles has run its own electric utility since 1892. The city says it now serves more than 15,500 customers, buys its power under a long-term agreement with the Illinois Municipal Electric Agency that runs until 2035, and takes delivery from ComEd at its 9 substations before distributing it on city lines.
For a home on the residential rate, the ordinance sets a monthly customer charge of $16.86 per meter and an energy charge of $0.1148 per kilowatt hour. In summer billing months, which start with bills in June and run four more months, usage above 1,200 kilowatt hours costs $0.1298 per kilowatt hour.
The city’s sample bill holds the electric portion flat at $96.90 from June 2026 through June 2029. That is the one piece of the bill moving in your favor.
Water: the biggest jump
Water is where most of the increase in St. Charles utility rates lands. For a meter of three-quarters of an inch or smaller, which is typical for a house, the ordinance sets these steps:
- Monthly customer charge: $27.17 in 2026, $36.68 in 2027, $40.35 in 2028, and $42.36 in 2029.
- Base rate per 1,000 gallons: $11.70 in 2026, $16.38 in 2027, $18.02 in 2028, and $18.92 in 2029.
- Excess seasonal rate per 1,000 gallons: $14.70 in 2026, rising to $21.92 by 2029.
The seasonal rate only applies to summer use that is more than 130% of your winter monthly average and more than 6,500 gallons a month. If you plan to water a big lawn or fill a pool, that is the line to watch.
Sewer and the EPA mandate fee
Sewer charges, the third piece of St. Charles utility rates, follow your metered water use. The residential monthly demand charge is $28.13 in 2026, $30.94 in 2027, $34.03 in 2028, and $36.76 in 2029, and the usage charge per 1,000 gallons goes from $8.83 to $9.72, $10.69, and $11.54 over the same years.
There is a helpful cap. Your sewer charge cannot exceed 130% of your average water use from the bills issued in January, February, and March, so summer watering does not inflate the sewer side. A newer home with no winter history is billed on actual use until it completes a winter quarter.
The ordinance also sets a monthly EPA mandate fee of $4.45, up from $2.75, to fund projects required by federal and Illinois environmental rules.
What the city’s sample bill looks like
The city’s utility rate schedule for 2026 through 2029 walks one typical residential bill forward:
- Before June 2026: $200.00 ($102.00 electric, $58.00 sewer, $40.00 water).
- June 2026: $234.67.
- June 2027: $269.28.
- June 2028: $286.52.
- June 2029: $298.31 ($96.90 electric, $83.37 sewer, $118.04 water).
The city estimates the first step as a net increase of about 17% for a typical customer and stresses that your own change depends on how you use water and power. Treat the sample as a starting point, not a quote for a specific house.
Why St. Charles bills are rising, and what it means for an older home
The city ties the new St. Charles utility rates to its 10-year utility plans. Its rate overview puts the lead service line replacement program at an estimated $84 million, with no state funding attached.
The timeline is the pressure point. In 2024, Illinois EPA updated its rules to require lead service lines to be replaced within 10 years instead of the 30 years the city had planned around, and the city says it has already put $11 million of reserves toward water work over the last 3 years.
The city also lists more than 80 miles of water mains that are 75 to 100 years old, plus sewer capacity for redevelopment such as the east side sanitary sewer trunk line. For the bigger picture on the projects behind that, see our roundup of St. Charles development and what is changing in 2026.
Some of the water increase is meant to be temporary
The city says a significant portion of the water increase is tied to the 10-year lead line timeline, and it plans to re-evaluate rates once that project is done. It is also asking state legislators for a longer timeline, so watch for changes, but do not budget on them.
The city says it is looking into a budget billing option that would spread payments evenly through the year. As of this writing it describes that as something under consideration, not a program you can sign up for.
The service line is partly your responsibility
Here is the detail that matters on an older house. According to the city, it is responsible for the water service from the main to the property line, and the owner is responsible from the property line to the building, including all the plumbing inside.
Lead was common in plumbing before the mid-1950s, and the city is surveying owners to identify service line materials. On any older home, ask the seller what the line is made of and have your inspector look where it enters the basement. We covered how another Fox Valley city handles this in our guide to lead service lines in Aurora.
Check the address before you trust the numbers
A St. Charles mailing address does not always mean city services, and St. Charles utility rates only apply inside city limits. One west side resident in that same Reddit thread said they were unincorporated and could not help with utility questions at all.
Kane County’s parcel records include a municipality field, and you can look up any address or PIN on the Kane County GIS parcel map. If the parcel is outside city limits, these rates may not apply, and the home may rely on a private well and septic system, which calls for a different inspection plan like the one in our septic inspection guide.
Trash is billed separately
For homes inside city limits, Lakeshore Recycling Systems is the city’s contractor, and you choose between stickers and a cart subscription. Prices effective July 1, 2026 are $4.05 per refuse or yard waste sticker, or a monthly cart rental of $24.68 for 35 gallons, $26.04 for 65 gallons, or $27.41 for 95 gallons, billed quarterly by LRS.
Recycling carts are free, and collection is Monday east of the river and Tuesday west of the river. Brush pickup is limited to homes that pay an extra monthly fee on the city utility bill, so check the seller’s bill to see whether it is included.
A short checklist before you make an offer
- Confirm city limits. Look up the parcel’s municipality on the county map before you assume city electric, water, and sewer.
- Ask for 12 months of bills. City statements show real seasonal swings for electric and water, which a sample bill cannot.
- Re-run them at 2027 rates. Apply the June 2027 steps in St. Charles utility rates so your budget reflects the bill you will actually pay next year.
- Ask about the service line. Find out whether it is lead, galvanized, copper, or plastic, and who would pay for any private side work.
- Pick your trash option. Decide between stickers and a cart, and whether the brush fee is on the account.
- Schedule the switch. Call Utility Billing at least one business day before your closing date, and have your attorney confirm the seller’s final reading.
