Wrong Electricity Tariff Category? How to Fix Your Bill at Home or Your Small Business

If your electricity bill suddenly looks too high, the cause is often a wrong tariff category — a domestic home billed as commercial, or a small shop pushed into an industrial slab. The good news is that this is usually correctable. This guide shows you how to read your bill, compare it against your real usage, get the DISCOM to reclassify your connection, and escalate to the regulator or ombudsman if it drags.

This guide is for any electricity consumer in India who believes their connection has been placed in the wrong tariff category and is being overcharged as a result. The tariff category decides your per-unit rate, your fixed charges, and sometimes your meter rent. A wrong category can quietly add thousands of rupees over a year. It is useful for:

• Homeowners and tenants billed at a commercial rate when the premises are purely residential.
• Shopkeepers and small businesses pushed into a high industrial or large-commercial slab when their load is modest.
• People running a small clinic, tuition centre, salon, or workshop from part of their home, unsure whether a mixed tariff applies.
• Consumers who got a back-dated arrears demand after a meter inspection reclassified their connection.
• Anyone who wants the inspection report or assessment file that triggered a tariff change.

The exact category names, slabs, and rules differ in every state because tariffs are set by each State Electricity Regulatory Commission. So treat the category labels here as examples and always check your own state's tariff order and your DISCOM's rules.

Take out your last three to six electricity bills. On each bill, find the tariff category field. It is usually printed near your name, consumer number, and meter number. Note the exact label, the per-unit rate, the fixed charges, and the sanctioned load. Photograph or scan every bill clearly.

Now ask a simple question: does the printed category match how you really use this connection? A home used only for living should normally be on a domestic tariff. A standalone shop is usually commercial. Write down in one line what the connection is actually used for. If the printed category and the real use do not match, you have a case to make.

If the higher bill started suddenly, look for the month it changed. A reclassification often follows a meter inspection or a flying squad visit. Note that month — you will ask the DISCOM for the inspection report behind it.

Build your comparison. Make a small table: bill month, units consumed, tariff category, rate per unit, and total amount. This makes the jump obvious and is the single most persuasive document you can hand the DISCOM. If you can find a neighbour with similar usage on the correct category, note their rate too as a reference point.

Gather your proof of use. For a home, that means address proof, a copy of the property tax receipt or rent agreement, and a few photos showing it is residential. For a shop or small business, keep the trade licence or shop establishment registration ready, because the DISCOM will look at the purpose of supply.

Check your DISCOM's website and consumer app for the online complaint or tariff-change request option. Many DISCOMs let you raise a category-correction request online and give you a docket or complaint number. Note the helpline number printed on your bill too.

Draft your written correction request using the template lower down this guide. Keep it factual: state your consumer number, the current category, the category you believe is correct, and the dates and amounts in dispute. Attach your bill comparison table and proof of use.

Decide your payment stance for the disputed bill. In most states you can pay the undisputed portion on time and flag the disputed part in writing as paid under protest. This protects you from disconnection while keeping your dispute alive. Confirm the exact procedure with your DISCOM, since the rules vary.

Get everything ready to submit on Monday — print two copies of the request so you can get one stamped as received, and keep digital copies for online filing and for any later escalation to the regulator or ombudsman.

Locate the tariff category on your bill. Depending on the state it may read Domestic, Commercial, Non-domestic, LT-1, LT-2, or an industrial code. Note the rate per unit and the fixed or demand charges tied to that category. Also note the sanctioned load in kW or HP. These are separate fields — a wrong category and a wrong load are different problems, and you may have one without the other.

Match the printed category to the real purpose of supply. Most state tariff orders classify connections by how the electricity is used, not merely by the type of building. A home used only for living should be domestic. A shop should be commercial. A small home-run activity may fall under a mixed or partly commercial rule that varies by state. Decide which category you believe is correct and write down why.

Lay your bills side by side in a simple table: month, units, category, rate, total. If a single inspection or a tariff revision caused the jump, this table will show it at a glance. A clear comparison is far more convincing to a DISCOM officer than a long complaint paragraph, and it becomes your core exhibit at every later stage.

Submit a written request to your DISCOM's local office or through its online consumer portal. State your consumer number, the current category, the category you say is correct, the disputed period, and the amount in dispute. Attach your bill comparison, proof of use, and photos. Insist on a dated acknowledgement or an online docket number. This first written request is the foundation for every escalation, so keep the proof of submission safe.

If the DISCOM changed your category after a site visit or inspection, ask in writing for a copy of the inspection report, the site notes, and the order or assessment that reclassified you. You are entitled to know the basis of a decision that increases your bill. If the DISCOM is a government-owned distribution company, you can also file an RTI for these records — see the RTI section below. For a wider walk-through of using RTI on electricity matters, see our guide on electricity complaints through RTI.

While the dispute is pending, protect your supply. In most states you can pay the undisputed portion and mark the disputed amount as paid under protest in writing. This keeps your meter running and your dispute alive at the same time. The exact procedure, any deposit, and whether interest accrues on the disputed amount depend on your state regulations, so confirm before you withhold anything.

If the DISCOM does not correct the category in a reasonable time, take it to the Consumer Grievance Redressal Forum (CGRF) for your distribution licensee. Every DISCOM in India is required to have such a forum. File your complaint with the same documents plus the DISCOM's reply or your proof that it did not reply. The CGRF can direct the DISCOM to reclassify and adjust your bill.

If you are not satisfied with the CGRF order, the next step is the Electricity Ombudsman appointed by your State Electricity Regulatory Commission. The Ombudsman hears appeals against CGRF decisions. Carry the full paper trail: your original request, the DISCOM reply, the CGRF order, and your bill comparison. For general consumer overcharging, you may also consider the consumer commission route; weigh both with the facts of your case.

The Right to Information Act, 2005 applies to public authorities. Many electricity distribution companies in India are government-owned, and these are generally treated as public authorities. Where that is the case, RTI is a powerful way to get the paperwork behind a tariff change that the DISCOM is slow to share:

• The inspection report and assessment file: Ask the Public Information Officer for a copy of the inspection report, site notes, photographs, and the order that reclassified your connection. Frame it plainly: “A copy of the inspection report and the order changing the tariff category of consumer No. [Your Number], with the name and designation of the officer and the date of the change.”
• The basis of the rate applied: Ask for the specific clause of the approved tariff schedule under which your connection was placed in its current category, and the internal note recording that decision.
• Status of a pending request: If your written correction request has gone unanswered, ask for its current status and copies of any internal noting on it.

To file your application, see our step-by-step guide on filing an RTI online. If the PIO does not reply or refuses, use our guide on filing a first appeal under RTI Section 19, and the broader first appeal and second appeal guide if it escalates. You can also escalate a stuck grievance through CPGRAMS along with RTI. For deeper strategy on using RTI in disputes like this, The RTI Playbook is a useful companion.

RTI has clear limits in a tariff dispute:

• RTI cannot correct your tariff: RTI gives you information, not a decision. Only the DISCOM, the consumer grievance forum, or the Ombudsman can actually reclassify your connection and adjust your bill. Use RTI to strengthen those steps, not to replace them.
• Private licensees may be outside RTI: Where your DISCOM is a private distribution licensee, RTI may not apply directly to it. In that situation, demand the inspection report through your consumer grievance forum instead, and seek any approved tariff records from the State Electricity Regulatory Commission, which is itself a public authority.
• RTI is not a fast track: The 30-day RTI timeline is slower than a well-pressed grievance. For speed, push the CGRF and Ombudsman routes; use RTI in parallel to get documents you are being denied.

• Complaining only by phone: A call to the helpline rarely creates a record. Always put the correction request in writing and keep the acknowledgement or online docket number. Without proof of your request, escalation becomes much harder.
• Stopping payment entirely: Withholding the whole bill invites disconnection and late fees. Pay the undisputed part and mark the rest as paid under protest in writing, following your state's procedure.
• Confusing category with load: A wrong tariff category and a wrong sanctioned load are two different issues. Read your bill carefully and raise the correct one, or both, as separate points.
• Assuming the building type decides everything: Most tariff orders look at the purpose of supply, not just whether the property is a house or a shop. A commercial activity inside a home can attract a commercial or mixed tariff under many state rules.
• Not asking for the inspection report: If a back-dated arrears demand lands after an inspection, you are entitled to know the basis. Ask for the report in writing, and use RTI if the DISCOM is a public authority and stalls.
• Skipping the comparison table: A clear month-by-month table of units, category, rate, and total persuades officers far more than a long letter. It is your strongest single exhibit at every stage.
• Missing the appeal window: If the CGRF rules against you, the Electricity Ombudsman appeal has a time limit set by state regulations. Diarise it the day you receive the CGRF order so you do not lose the right to appeal.
• Guessing the correct rate from another state: Categories and rates differ in every state. Always rely on your own State Electricity Regulatory Commission's tariff order, not a figure you saw for another state.

If you also received a suspicious payment demand or link, do not act on it before reading our guide on the electricity bill scam over WhatsApp and SMS, because fake disconnection messages often ride on genuine billing confusion.

• Central Electricity Regulatory Commission (cercind.gov.in) — Central regulator; useful for the regulatory framework and orders
• National Consumer Helpline (consumerhelpline.gov.in) — Register a consumer grievance, including overcharging complaints
• CPGRAMS (pgportal.gov.in) — Public grievance portal for central and many state government bodies

For your own state, search for your State Electricity Regulatory Commission and your DISCOM's official website to find the current tariff order, the Consumer Grievance Redressal Forum, and the Electricity Ombudsman.

Your bill shows the tariff category, often printed as a code or words such as Domestic, Commercial, LT-1, LT-2, or Industrial near the consumer details. The applicable rate per unit, sanctioned load, and meter number appear on the same bill. Compare the printed category against how you actually use the connection. If they do not match, you may be on the wrong tariff.

It depends on the state regulations and the facts. Where the DISCOM accepts that it misclassified the connection, many utilities adjust the difference as a credit in future bills or process a refund. Where the higher category applied because of how you used the premises, the utility may instead raise arrears. The exact period, interest, and adjustment rules vary by state electricity regulatory commission, so ask the DISCOM to put its decision in writing.

Often yes. Most state tariff orders classify usage by the purpose of supply, not just the building type. If a part of your home is used for a shop, clinic, tuition centre, or other commercial activity, the DISCOM may apply a commercial or mixed tariff to all or part of the load. The precise rules, including any mixed-load provisions, are set by your state electricity regulatory commission and vary state to state.

Tariff category is the rate slab applied to your connection based on the purpose of use, such as domestic or commercial. Sanctioned load is the maximum power, in kW or HP, your connection is approved to draw. A wrong category changes your per-unit rate and fixed charges; a wrong load can trigger penalties or a different slab. Both are separate fields on the bill and can each be corrected through the DISCOM.

Each State Electricity Regulatory Commission, or the Joint Commission for some union territories, approves the tariff schedule for its distribution licensees through a tariff order. The DISCOM then applies those categories to each connection. So the categories and rates come from the regulator, while the day-to-day classification of your specific connection is done by the DISCOM.

If your DISCOM is a public authority, such as a state-owned distribution company, you can file an RTI with its Public Information Officer for the inspection report, site notes, and the file that led to your tariff reclassification. Where the DISCOM is a private licensee, RTI may not apply directly, but you can still seek records from the state regulatory commission or use the consumer grievance forum to demand the report.

Usually yes. Stopping payment can lead to disconnection, late fees, and a weaker position before the grievance forum. A common approach is to pay the undisputed portion on time and clearly mark the disputed amount in writing while your complaint is pending. Check your DISCOM's rules and the grievance forum's directions, because the right to pay under protest and any required deposit vary by state.
