“We're From the Electricity Utility, Here to Swap Your Meter” — Real or a Scam? The 4 Checks
A phone call, a LINE friend request, or someone at your gate saying they are a utility officer here to change your meter — the one question you must answer first is whether they are real. This page collects what the Metropolitan Electricity Authority (MEA) itself announced this Aug–Sep: the Smart Meter swap is always free, the four points that identify a genuine officer, the three scam patterns now circulating, and who to call if you already fell for it.
The short answer: MEA swaps meters to Smart Meters “free, with no charge whatsoever” — so if money is being collected on the spot, assume a scam immediately. A genuine officer will never ask you to scan a QR code, add a LINE account, or open any private contact channel. If in doubt, end the conversation and call back on a number you dialled yourself: MEA 1130 (24 h) or PEA 1129.
Does a Smart Meter swap cost anything?
How do you tell a real officer? MEA's 4 identification points
Always free — swapping to a Smart Meter is an MEA service that is “free, with no charge whatsoever”. If money is collected on site, assume a scammer immediately.
Advance notice, always — MEA always gives users in the area written notice or a public announcement before it comes to do the work. It does not simply turn up.
Uniform + ID card — contracted field workers must wear the standard outfit: dark-grey shirt and trousers, orange across the shoulders and upper back, silver reflective strips on chest and back, the words “ผู้รับจ้างเหมา การไฟฟ้านครหลวง” (MEA contractor) printed clearly on the back, and an identification card worn on the chest at all times.
No QR code, no LINE — field officers will absolutely never ask a customer to scan a QR code, add a LINE account, or open any private contact channel.
What are the 3 scam patterns being reported?
| Pattern | How it runs | The tell |
|---|---|---|
| Call or fake LINE: “your meter is faulty” | They claim the meter reader found a fault and the meter must be replaced free of charge, then push you to add a fake LINE account, send a photo of your bill, share your screen or tap a link. Some invent a “meter guarantee certificate” you must prepare. | The real target is your personal and financial data, later used to impersonate your bank or another agency for a second round — MEA has no policy of officers contacting people through a personal LINE account. |
| At your door, in the name of a state project | They pose as a state agency, or offer to “facilitate” the Smart Meter swap, and then charge a service fee. Some ask you to scan your face to “claim the entitlement”. | MEA swaps Smart Meters free of any charge and has no policy of sending staff door-to-door to collect money or to ask for a face scan to claim an entitlement. |
| Threats and urgency: “transfer to be verified” | Posing as a government officer or a call centre, they frighten the victim and press for an immediate decision to transfer money. | MEA and government agencies absolutely never phone or send a link asking you to transfer money for verification. Hold to the rule “don't believe, don't rush, don't transfer”. |
How do you verify the utility's real LINE account?
MEA's correct LINE Official Account must carry the name “MEA Connect”, LINE ID @MEAthailand, with the green Verified shield beside the account name — and nothing else. MEA warns that you must not judge by the display name, profile picture or logo alone, because scammers can copy all of those.
MEA also confirms it has no policy of officers making contact through a personal LINE account to ask you to share your phone screen, open notification messages, grant app permissions, tap links, reveal a password or OTP, or carry out financial transactions. The Smart Meter swap under MEA's programme is free, and there is no need for any transaction by phone or bank account at all. To check a balance or manage a service yourself, open the official PEA Smart Plus / MEA Smart Life apps yourself instead of tapping a link someone sent you.
You already shared your screen, tapped the link or transferred — now what?
Work through these in order, as fast as you can — every number below comes from MEA's own announcements.
1. Stop immediately
End the conversation at once. Do not tap links, do not install applications, do not share your screen, and send no further photos of your bill or personal data to an account you do not know.
2. Verify with the utility on a number you dial yourself
Call MEA Contact Center 1130, 24 hours (or PEA 1129) and ask whether meter work in your area is genuine. Do not call back on the number the contact gave you. For the Khlong Toei area MEA lists 02-249-1371 (24 hours) and 02-348-5238 (07.30–15.30) for verification.
3. If data or money already went out, call 1441
MEA points to the online-crime hotline on 1441 — call it at once. The sooner it is reported, the better the chance of limiting the damage.
4. Report the impersonator
If you see a suspicious person impersonating an MEA officer or fishing for personal data, report it to MEA Call Center 1130, 24 hours. And whenever someone comes to your premises, always ask to inspect their staff ID card first.
What this page does not answer (and where to look instead)
This page answers one question: is the person contacting me real or a scammer? If your question is a different one:
• How a digital/smart meter differs from a dial meter, and whether the bill really rises after the swap — read that page; this one does not explain the meter itself. • An abnormally high bill, suspected leakage or a wrong meter — that is a billing problem, not an impersonation one. • You have paper from the utility and are unsure which is a real bill and which is an arrears notice — that page separates the *documents*; this one separates the *people and channels*. • Penalties for meter tampering — that is where the customer is the offender, the opposite of being a victim. • Being cheated over a solar installation rather than a meter — a different industry; read that page instead.

Compiled by the CapSolar team, a commercial solar provider in Thailand, and reviewed by Frank Lee (Founder). The whole page cites four Metropolitan Electricity Authority (MEA) warning announcements published between 30 Aug and 6 Sep 2026, whose accessibility we verified on 8 Sep 2026 — the quoted lines are MEA's own wording. **We print no fine, fee or loss statistic the utility has not published**, because a safety page that invents numbers is more dangerous than no page at all. Confirm area-specific details on 1130 (MEA) / 1129 (PEA).
