A NERC billing complaint letter is a formal, written notice you send to your electricity distribution company’s Customer Complaints Unit, stating your account details, the billing problem, and the remedy you want, before escalating to NERC itself.
Most guides explain the complaint process but leave you to write the actual letter from scratch. This page gives you the letter itself, with every field marked so you can fill it in and send it today.
The full escalation timeline lives in a separate guide, linked further down.
What to include in a NERC billing complaint letter
A usable complaint letter needs six things: your identity and address, your account and meter number, the DisCo you are writing to, a clear description of the billing problem, the specific rule or reason the bill is wrong, and the outcome you want.
Skip any of these and the complaints unit has an easy excuse to sit on your letter. Keep the tone factual rather than angry, and state plainly what happened, when, and what you want done about it.
Attach copies of the disputed bill and past bills showing your normal usage, since the officer will compare them anyway.
Date the letter, keep a copy, and get a stamped or emailed acknowledgment when you submit it. That acknowledgment becomes your proof if you need to escalate later.

[DisCo Business Unit / District Office Address]Subject: Formal complaint regarding billing error on account [Account Number]
Dear Sir/Madam,
I am a registered customer of [DisCo Name] with account number [Account Number] and meter number [Meter Number], resident at [Your Address]. I am writing to formally dispute a bill I received dated [Bill Date], which charged me [Amount in Dispute] for the billing period [Billing Period].
The bill is incorrect for the following reason: [describe the issue, for example: my meter was not read and the bill is an estimate far above my usual consumption; or I was billed on a tariff band that does not match the supply hours I receive; or my prepaid meter’s token cost does not match the units purchased].
Under the NERC Order on the Capping of Estimated Bills, an unmetered customer should not be billed above the average of their last three months of actual consumption. [Delete if not disputing an estimated bill.] I also believe this bill does not reflect the service band actually delivered to my area. [Delete if not disputing a band mismatch.]
I have attached copies of the disputed bill, my last three bills for comparison, and [any photos, meter readings, or token receipts relevant to your case] in support of this complaint.
I request that [DisCo Name] investigate this bill, adjust it to reflect my correct consumption or tariff band, and issue a corrected bill promptly. I would also appreciate a written acknowledgment of this complaint, including a reference number.
Please contact me on [Your Phone Number] or [Your Email Address] if you require further information.
Yours faithfully,
[Your Full Name]
[Your Signature, if submitting a printed copy]

| Placeholder | What to enter |
|---|---|
| [Your Full Name] / [Your Address] | Your legal name and the address tied to the account, not a different property. |
| [Account Number] | The account number on your bill, not your meter number. |
| [Meter Number] | The number printed on your prepaid or postpaid meter. |
| [DisCo Name] | The specific distribution company on your bill, for example, Ikeja Electric, EKEDC, or AEDC. |
| [Amount in Dispute] / [Billing Period] | The naira figure you dispute and the exact month it covers. |
| [Bill Date] | The date printed on the disputed bill, not today’s date. |
How to fill in the account and meter details correctly
Get your account and meter numbers exactly right, since a mismatched number is the single most common reason DisCos delay or ignore a complaint.
Both usually appear on a recent bill, but if you cannot find yours, or suspect it changed after a meter swap, check your prepaid meter number directly on the meter before submitting the letter.
Also confirm the account name matches the person the account is registered to, since a complaint filed under a tenant’s name for a landlord’s account often gets bounced back unresolved.
Arandmi lets residents rate the power and internet reliability where they actually live, street by street, so if you are dealing with constant estimated bills or unstable supply, you can see what neighbors nearby are reporting before committing to a new address.
Which NERC rule to cite for your type of dispute
Cite the rule that matches your problem, since a generic reference to “NERC regulations” carries less weight than the specific order that applies.
| Dispute type | What to cite |
|---|---|
| Estimated bill with no meter reading | The NERC Order on the Capping of Estimated Bills and the three-month average consumption rule. |
| Sudden bill spike with a working meter | Request a meter accuracy test and cite your last three bills as evidence of normal consumption. |
| Wrong tariff band or mismatched supply hours | Reference the Service Based Tariff structure and ask the DisCo to confirm the band officially assigned to your feeder. |
| Prepaid token cost does not match units received | Request a transaction log from the DisCo’s vending platform alongside the bill correction. |
If your dispute is tied to a recent tariff adjustment rather than a metering error, it helps to understand the history of Nigeria’s electricity tariff increases so you can point out exactly which change your bill seems to be misapplying.
What to attach to your letter
Attach documents that let the officer verify your claim without asking for more information.
- A clear copy or photo of the disputed bill showing the amount, date, and billing period.
- Your last two or three bills, so the officer can compare your normal usage against the disputed one.
- A recent photo of your meter display or nameplate, if the dispute involves a reading or metering fault.
- Prepaid token purchase receipts or SMS confirmations, if the complaint concerns unit shortfall.
- Any prior correspondence with the DisCo about the same issue, since it shows the problem is not new.
If your complaint touches on how many hours of power your area receives, it is worth confirming you check your electricity band first, since a wrongly assigned band is a common cause of inflated charges.
How and where to send the letter
Send the letter to the Customer Complaints Unit at your local DisCo business unit, either by hand delivery with a stamped copy for your records, or by email if the DisCo publishes a complaints address.
A stamped, dated copy is harder for the office to lose track of than an email sitting unread, so if you email it, ask for a reply confirming receipt and follow up by phone if you hear nothing.
Keep that stamped copy or email confirmation somewhere safe as proof you complained within the required window, in case the matter needs to go further.
What happens after you send it
Once your DisCo receives the letter, it must investigate and respond within a set number of working days, and if it fails to resolve the issue or does not respond, you have the right to escalate to NERC directly.
This page focuses on the letter itself, since the full step-by-step NERC complaint process is covered in a separate guide.
If your DisCo goes quiet, reach NERC’s call centre on 02013444331 or 09088999244, email complaints@nerc.gov.ng, or open a ticket at nerc.freshdesk.com.
Before sending your letter, it helps to know what questions readers in the same situation tend to have, since a few small details trip up most first-time complainants.
Frequently asked questions
What should a NERC billing complaint letter include?
It should include your name and address, your account and meter number, the DisCo’s name, a clear description of the billing error, the rule it breaches, and the remedy you want.
Leaving out the account or meter number is the most common reason a letter gets delayed, since the officer cannot match it to your connection.
Attach past bills or meter photos, and always request a written acknowledgment with a reference number as proof of when you complained.
Can I dispute my electricity bill without a functional meter?
Yes, and this is one of the most common billing disputes in Nigeria, since customers without a meter are billed on an estimate rather than actual consumption.
Under NERC’s Order on the Capping of Estimated Bills, an unmetered customer should not be charged more than the average of their last three months of verified consumption.
Cite that rule directly and attach your previous bills as evidence.
Can I send my complaint letter by email instead of delivering it in person?
Yes, most DisCos accept complaints by email, though a hand-delivered copy stamped with a date and reference number is often easier to track than an email sitting in a shared inbox.
If you choose email, send it to the address published for your DisCo’s Customer Complaints Unit and ask for confirmation of receipt, then keep that reply as proof of submission in case you need to escalate later.
What happens if my DisCo does not respond to my letter?
If your DisCo fails to respond or does not resolve the issue within the required period, you have the right to escalate directly to NERC, which can investigate and order a correction.
You can reach NERC through its call centre, by email at complaints@nerc.gov.ng, or through its online support portal.
The full escalation steps and timelines are covered in a separate guide on filing a NERC complaint against your DisCo.
A clear, well-documented letter is often enough to get a billing error corrected without ever needing to escalate further, so take the extra ten minutes to fill in every field accurately before you send it.
