I Switched Electricity Suppliers. Why Didn’t My Bill Go Down?

You changed electricity suppliers for a lower rate, then opened a bill that was just as high or higher. That result deserves a closer look. It does not, by itself, prove that the switch failed or that the new supplier overcharged you.

There are two different questions: Did my total bill fall? and Did the new supply arrangement cost less than the alternative for the electricity I actually used? A higher bill can coexist with real savings. A lower advertised rate can also cost more once fees are included. This guide helps you separate those outcomes using your own documents.

The method is for residential electricity accounts where supplier choice is available. The examples use a simple supply-and-delivery bill; they are not a tariff for any state. Texas retail plans need the adjustments explained below. Municipal utilities, cooperatives, aggregation programs, solar credits and specialized tariffs can follow different arrangements.

Confirm that the new supplier is actually on this bill

Start with the service dates, supplier name and effective date, not the bill's issue date or payment due date. A bill received after enrollment may cover electricity used before the switch. Keep the enrollment confirmation and ask for the actual service-start date if the documents disagree.

Do not assume switching always takes an entire billing cycle. For example, Pennsylvania's official shopping FAQ says a change can likely occur within three business days after the distribution company is notified. That is a Pennsylvania explanation, not a nationwide deadline or a guarantee that your first statement contains only the new supplier's charges.

If the bill spans two suppliers, identify the dates and kWh assigned to each. Ask for the allocation used to calculate the bill. Do not divide usage evenly by calendar days unless the billing records support that method: heating, cooling and other consumption need not be evenly distributed.

Also establish whether you receive one bill or two. West Penn Power's customer-choice guide describes both combined billing and separate distribution and supplier bills. Add distinct charges for matching service periods, but do not count supplier charges twice when they already appear on a combined bill.

Build a comparison from charges, not just the amount due

Gather the last full bill before the switch, the first full bill under the new supplier, the contract or price sheet, and any final bill from the previous supplier. If your utility provides a usage download, keep it alongside the statements. Record the following in a notebook or spreadsheet.

For example, a $200 payment demand containing $40 carried forward is not a $200 charge for this month's electricity. Reconcile the balance separately before comparing current-period costs. A refundable deposit affects cash flow, but should not silently become a recurring energy cost in your comparison.

PAPowerSwitch explains that Pennsylvania distribution service remains with the utility after a supply switch. Its Price to Compare concerns the competitive generation portion, not the whole household bill. Our supply-versus-delivery guide explains the distinction in more detail.

Reprice the same usage: a bill can rise while you save

The useful comparison holds the service period and electricity use constant, then applies the two sets of prices and fees. Here is a fully hypothetical example. Both example billing periods have 30 days. Delivery rates and the fixed delivery charge stay unchanged. There are no taxes, riders, credits, deposits, late fees or cancellation charges in this simplified illustration.

This distinction prevents two mistakes: calling any higher bill proof of a bad switch, or calling a 20% reduction in the supply rate a 20% reduction in the total bill. At the original 800 kWh, the new arrangement would total $123, only $9 below $132 after the fee and delivery charges.

Choose an honest benchmark. The last column assumes the old terms would still apply. If that contract expired, the old 10¢ rate may no longer be available. For a decision about staying or switching again, calculate the alternative actually available for the same service period, such as the applicable utility default price. Label a calculation using expired prices as a historical comparison, not an achievable saving.

Check fees, partial periods and credits before judging the switch

For a simple flat supply price, use: kWh × dollars per kWh + recurring supplier fees − eligible supplier credits. Compare like components. Delivery and taxes can cancel out only when they are identical under both alternatives; otherwise include their differences too.

In the example, the 2¢ rate advantage offsets the $7 fee at 350 kWh: $7 ÷ $0.02. Below that point, the supplier's recurring supply charge is higher. At 200 kWh it is $23 instead of $20. This threshold applies only to these invented flat-price terms, without other fees or credits.

A mid-cycle switch needs another adjustment. Suppose a 1,000-kWh statement allocates 400 kWh to an old 10¢ rate and 600 kWh to a new 8¢ rate. Supply usage costs $40 + $48 = $88, not $80. If a full $7 new-supplier fee applies under the contract, supply totals $95. Check the actual fee-proration rule; do not assume every fee is split by days.

The Pennsylvania contract-summary guidance identifies price structure, introductory terms, incentives, start dates and cancellation fees as items to review. Apply promised credits only when their eligibility conditions are met. Record a missing earned credit as a question for the supplier, with the contract provision and qualifying usage attached.

For an introductory or variable price, use the rate actually applicable to each period. A good first bill does not establish a year of savings. Keep a running comparison over subsequent bills, and use our contract-renewal checklist before the current terms end.

Use the right calculation for your tariff

In Texas areas with competitive retail electricity, distinguish a provider's energy-charge line from the average price on its Electricity Facts Label (EFL). PUCT rule §25.475(g) requires residential averages at 500, 1,000 and 2,000 kWh. Those averages reflect recurring charges; the rule excludes specified taxes. They are not simply the provider's energy rate.

Rebuild the cost at your actual usage from the EFL's components. Do not add delivery charges a second time to an average price that already includes them. Check thresholds for usage credits, base charges and the relevant transmission and distribution utility's charges. A 1,000-kWh example is not a promise of the same average price at 700 kWh. Variable-price EFL disclosures describe the first billing cycle, with subsequent changes governed by the applicable terms and rules.

For time-of-use pricing, a monthly kWh total is insufficient: compare the same usage in the relevant time bands. Our hourly-data comparison guide shows the method. Tiered prices, demand charges, solar exports and community-solar credits also need their own quantities and rules. Do not force a complicated plan into the flat-rate formula.

Explain the remaining change in the bill

Once you have checked the supplier's portion, look at the other lines. Con Edison's billing FAQ identifies longer billing periods, estimated readings, seasonal use and added appliances as reasons bills can change. Its guidance is specific to that utility, but these are useful fields to inspect on your own statement.

Compare kWh per day when billing periods differ. For instance, 800 kWh over 32 days and 750 kWh over 30 days both equal 25 kWh per day. That does not prove identical weather or habits; it simply removes the effect of period length from this first check. Use the high-bill diagnostic guide if the daily usage itself rose.

Separate the energy charge from a budget-plan payment. Con Edison's Budget Billing description explains that payments are spread across the year and may be adjusted, with differences reconciled. Your own utility's arrangements can differ. Look at actual charges and the accumulated balance, not just the monthly debit.

An estimated reading, catch-up adjustment, changed delivery rate or past-due balance needs its own explanation. Ask for the affected dates and calculation. Do not attribute an unexplained adjustment to the supplier merely because it appeared after enrollment.

Turn the result into a specific request

Write down your finding before calling: the new supplier is not yet active; it is cheaper at the same usage but consumption rose; fees erased the rate advantage; or the billed charge does not match the agreed terms. If you cannot choose one, list the missing information instead of guessing.

My bill covers [dates] and shows [kWh]. The supplier began on [date]. My contract lists [rate] and [fees], but the bill shows [charge]. Please confirm the usage allocated to each supplier, explain the calculation and any credit conditions, and identify the effective date and amount of any correction.

Use verified contact details from the bill or official website. Send the supplier questions about its price, fees or credit; direct meter readings, delivery charges and account-balance questions to the utility or the responsible billing provider. Keep the case number, documents, response and promised follow-up date.

If the explanation remains unresolved, use the regulator or consumer office responsible for your account. The Pennsylvania PUC complaint page, for example, generally requires contacting the utility first and recommends its informal process for typical billing concerns. Jurisdiction and complaint protections differ elsewhere. Do not assume that raising a dispute pauses payment obligations; ask what to pay while the issue is reviewed.

If the new terms are simply expensive, compare an available replacement at your usage and include any applicable exit fee. Confirm the switch date rather than requesting a shutoff. The useful outcome is a documented cost comparison and a clear next action, whether that means keeping the plan, correcting a bill or arranging a better supply contract.
