Utility Bill Spike Investigator

Safety Boundary

This skill helps organize facts before the user contacts a utility, telecom, landlord, building office, or consumer protection resource about an unexpectedly high bill. It is administrative guidance only, not legal, financial, engineering, or regulatory advice.

Do not fabricate evidence, bypass meters, tamper with equipment, impersonate another person, or share full account numbers, passwords, payment details, identity documents, or private access codes. Use official provider channels and local consumer protection resources for unresolved disputes.

When to Use / When Not to Use

Use this skill when the user:

• Receives a sudden electricity, gas, water, internet, mobile, landline, trash, or bundled-service bill increase.
• Wants to compare usage, rate changes, fees, taxes, and plan changes before calling support.
• Needs a factual evidence log, call script, and follow-up tracker.
• Wants to decide what to ask for: explanation, correction, meter check, plan review, payment arrangement, or escalation.

Do not use this skill to:

• Give legal advice or decide whether the user has a valid legal claim.
• Bypass, alter, inspect dangerously, or tamper with meters or utility equipment.
• Avoid paying bills through unsafe or fraudulent tactics.
• Request sensitive information that is not needed for analysis.

Privacy Rules

Ask for partial or summarized information only:

• Good: provider name, bill type, service period, total amount, previous total, usage units, rate line items, due date, fees, plan name.
• Avoid: full account number, full address, payment card, bank details, Social Security number, national ID, passwords, security answers, full bill images.
• If the user pastes a bill, tell them to redact account numbers, barcodes, payment details, and personal identifiers first.

Five-Step Workflow

1. Capture the bill snapshot. Record bill type, provider, service period, due date, total amount, previous amount, usage amount, usage unit, and any shutoff or late-fee deadline.

2. Compare what changed. Separate usage change from rate change, fixed fees, taxes, one-time charges, deposits, adjustments, estimated readings, discounts that expired, and plan changes.

3. Build an explanation and evidence list. Identify household events, weather, leaks, appliance changes, guests, travel, billing-cycle length, meter readings, service outages, roaming, overage charges, or promotional endings.

4. Draft the support message or call script. Keep it factual, concise, and specific. Ask for an itemized explanation, correction review, meter or usage review, plan review, and case number.

5. Track escalation, payment, and follow-up. Record who was contacted, when, what they said, confirmation numbers, promised deadlines, payment arrangement options, and the next escalation date.

Comparison Checklist

Usage

• Did usage increase, or did only the price increase?
• Is the billing period longer than usual?
• Was the reading estimated last month and corrected this month?
• Is the meter reading on the bill close to the current meter or portal reading?
• Did weather, guests, travel, new appliances, leaks, irrigation, charging, or remote work change usage?

Rates and Plan

• Did the per-unit rate change?
• Did a promotional discount end?
• Did the account move to a different plan, tier, time-of-use schedule, or contract term?
• Are new delivery, demand, equipment, modem, rental, regulatory, or regional fees listed?
• Did taxes or government surcharges change?

Provider or Account Events

• Was service started, stopped, transferred, reconnected, or moved?
• Were late fees, deposits, returned-payment fees, installation charges, or equipment charges added?
• Was a prior credit removed or reversed?
• Was autopay, paperless billing, low-income assistance, or bundle discount removed?
• Did the provider issue a correction for earlier months?

Service-Specific Checks

For any meter-related check, stay safe: read visible displays only if accessible without entering restricted areas, opening equipment, climbing, or touching utility hardware.

Evidence Log

Support Call Script

Use this as a starting point:

"Hi, I am calling about an unexpected increase on my [service type] bill for [service period]. My total changed from about [previous amount] to [current amount]. I have compared the bill and want help understanding whether the increase came from usage, rates, fees, an estimated reading, a plan change, or a one-time charge. Can you review the account and explain the specific line items that changed?"

Follow-up questions:

• "Was this bill based on an actual or estimated reading?"
• "Did my rate, plan, promotion, or contract term change during this period?"
• "Are any one-time fees, deposits, equipment charges, late fees, or corrections included?"
• "Can you compare this period's usage with the same period last year?"
• "If this appears incorrect, what review, adjustment, meter check, or dispute process is available?"
• "What is the case number and when should I expect an update?"
• "If the review will take time, what payment arrangement or hold option is available to avoid late fees or service interruption?"

Written Message Template

Subject: Request for explanation and review of unexpected bill increase

Hello [Provider Name],

I am requesting a review of my [service type] bill for [service period]. The total amount increased from approximately [previous normal amount] to [current amount]. I would like an itemized explanation of the change, including usage, rates, fixed fees, taxes, one-time charges, estimated readings, plan changes, discounts, or corrections.

Please confirm:

• Whether the reading was actual or estimated.
• Which line items changed from the prior bill.
• Whether any plan, promotion, contract, equipment, or fee changes occurred.
• What correction, review, meter check, dispute, or payment arrangement options are available if the amount is incorrect.

Please provide a case number and expected response date.

Thank you, [Name]

Follow-Up Tracker

Escalation prompts:

• If no response by the promised date, contact the provider again with the case number.
• If the explanation is incomplete, ask for a line-item comparison in writing.
• If service interruption is possible, ask about payment arrangements while review is pending.
• If unresolved, look up official local consumer protection, public utility commission, telecom regulator, tenant resource, or legal aid information. Do not assume the correct authority without checking the user's location and service type.

Output Format

When using this skill, produce:

1. A privacy note reminding the user to redact sensitive information.
2. A bill-spike snapshot table.
3. A comparison checklist separating usage, rates, fees, and account events.
4. A service-specific evidence list.
5. A support call script or written message.
6. A follow-up tracker with deadlines and escalation prompts.

Example Prompt

"My water bill doubled this month. Help me figure out what to check before I call the utility. The bill covers 34 days, says actual reading, and usage is much higher than last month."

Differentiation: Produces a practical investigation packet for support calls and disputes, with privacy limits and evidence tracking instead of generic budgeting advice.
