The numbers, and the one question to ask at signing. - Author: Somchai Jaidee - Tags: Money & Costs, Practicalities The bill arrived on the second of the month and I read it as a mistake, twice, then as a joke, then as a sign I had been overcharged, then as a sign I had not been overcharged. Three thousand four hundred baht. For a one-bedroom. For [air conditioning](https://easythailandvisa.com/thailand-hotel-basics-ac-hot-water-wifi/) and a fridge and a laptop and nothing else. The landlord told me the rate had gone up. The rate had not gone up. The building was charging me nearly two baht more per unit than the national tariff, and nobody had lied to me, exactly. Last verified 5 October 2026, against the current ERC and provincial tariff schedule. The fuel adjustment charge moves about four times a year, so the exact figure you pay depends on the period you are billed in. ## First, what a "unit" is Thailand sells electricity **by the unit, and a unit is exactly one kilowatt-hour**. There is no conversion, no fuel-adjustment ambiguity of the kind the UK has, and when a bill says 412 units you used 412 kilowatt-hours, which is the same as 412 units of electricity anywhere else in the world. ## What a unit actually costs you now Residential electricity is charged on **progressive tiers**: the first block is cheap, the next block costs more, the block above that costs more again. There is no standing charge worth mentioning and no demand charge. For the current 2026 period the numbers sit around these: **About 3.88 baht per unit** was the average for the January–April 2026 billing period. For the May–August 2026 period the average rose to about **3.95 baht per unit**, which already includes the fuel surcharge — the *Ft*, currently around **0.16 baht per unit** — but **not** the 7% [VAT](https://easythailandvisa.com/thailand-vat-refund-for-tourists/), which is added at the end. The underlying tiers work out at roughly **3.25 baht for the first 150 units, about 4.22 for the next 250, and about 4.42 above that**, plus the fuel surcharge, plus 7%. So the real answer to "what is electricity in Thailand" is: **nearly four baht a unit, about 4.2 once you include tax, and a long way below what most of Europe pays** — as long as you are on the national tariff. ## The markup, and the question that finds it Here is the part that costs you money and takes ten seconds to avoid. Small homes on a provincial or metropolitan meter pay the tariff above. **A rental room, dormitory or serviced apartment may not legally be charged more than about 4.88 baht per unit** — that is a consumer-protection cap, and a landlord pushing past it is not being clever, they are breaking the rule. Condos are different, and this is the trap. **Many buildings buy power in bulk on one meter and re-sell it to residents at a private flat rate, commonly six to nine baht a unit.** That is not illegal in the same way, and it is not a scam, and it is the single most common reason an expat in Thailand discovers their electric bill has doubled. Ask, before you sign anything: **"Is my unit on its own PEA or MEA meter, or is it on the building meter?"** If it is the building meter, ask for the rate in writing. Then do the arithmetic before you move in rather than after. **A worked example, one bedroom, AC running six to eight hours a day.** 500 units at the national rate is about **2,100 baht** with tax. The same 500 units on a building meter at 7 baht is **3,500 baht**. Nobody did anything criminal in either case. The difference is 1,400 baht a month, and the only way to know which one you are getting is to ask in the first ten minutes. ## Water, and why a high bill is suspicious Water is **genuinely cheap** on the national rate: usually around **100 to 300 baht a month for one person, and 200 to 500 for a household**. It is the least important line on the bill and it is the one that will tell you a building is re-billing you. The tell is simple. **Buildings that re-sell water commonly charge 18 to 25 baht per cubic metre**, several times the national rate, which is how a 150 baht bill quietly becomes 350\. If your water bill jumps when you move in and your flat is the same size as the last one, this is why. ## Internet, and the fourth bill nobody mentions [Fibre](https://easythailandvisa.com/thailand-internet-wifi-speed/) is fast and cheap: **300 to 500 baht a month** gets you 500 Mbps or a gigabit line, and in most of the country the symmetric speeds are genuinely symmetric. That bill is straightforward *unless* the building resells it, which some older buildings do, so check whether the number on your internet bill is the number on your telco's invoice. And the fourth thing that shows up in month two, which is not a utility at all: **a common-area fee** charged by the building for cleaning, security, gym and parking. Budget for it separately, because it is often larger than your water bill and it is not negotiable after you have moved in. ## Two chores you have to do in the first fortnight **Put the meter in your name.** The electricity and water meters should be transferred from the previous tenant or the landlord — *ย้ายชื่อมิเตอร์* — at the provincial or metropolitan electricity office and the local water office. It usually takes a working day and it needs your passport, your [lease](https://easythailandvisa.com/buying-property-in-thailand-foreigner-lease-rules/) or a document from your landlord, and sometimes a signature from the owner. **Do it early.** The failure mode is not a bigger bill; it is a bill you cannot query because the account is in someone else's name. **Ask for the no-outstanding-balance certificate** at handover. On a shared building meter especially, an old debt left on the account becomes your problem with no way to prove otherwise. ## What I would actually remember Electricity in Thailand is not expensive and water is almost free. The expensive thing is **not knowing which meter you are on**, and the single question that fixes it costs you nothing to ask. Ask it in the first ten minutes, get the rate in writing, do the multiplication, and your bill will be boring for the rest of your stay. Mine would have been 2,100 instead of 3,400, and I would have spent that difference on a great many better things. **More on this** - [I Washed My Clothes in a Laundromat in Chiang Mai for 60 Baht](https://easythailandvisa.com/laundry-in-thailand-laundromat-washing-clothes/) - [The 220 Baht Your Bank Does Not Tell You About](https://easythailandvisa.com/thai-atm-fees-explained/) - [Your Bank Called to Say the Card in Thailand Was Captured,](https://easythailandvisa.com/atm-and-card-fraud-in-thailand/) - [When to Stop Converting the Baht in Your Head](https://easythailandvisa.com/thai-baht-conversion-mindset/) - [Your First Seventy-Two Hours Decide Whether the Trip Went Well](https://easythailandvisa.com/thailand-first-72-hours-when-you-land/)
