Dorm & Rental Electricity Law 2026: Can a Landlord Overcharge?
Living in a dorm, rented room or condo and wondering whether the 7-8 baht/unit your landlord charges is even legal? This page summarises what Thailand's OCPB (สคบ.) law says about rental electricity, your rights as a tenant, how to tell if you're being over-charged, and the complaint channels that actually work.
Under Thailand's consumer-protection law (สคบ./OCPB), which makes “leasing a building for residential living” a contract-controlled business, a dorm/rental landlord may NOT charge electricity at a rate exceeding what the electricity authority actually charges — i.e. no profiteering on electricity. If a lease writes in an inflated electricity rate, that clause “has no legal effect” even if you signed it. The latest notification (B.E. 2568) sets an explicit ceiling: a landlord may bill a tenant “no more than 4.88 THB/unit”. The rate you should actually pay tracks the utility at around 3.95–4 THB/unit (it moves with the Ft each period), not the 7-8 baht many dorms collect. If you suspect over-charging, gather your bills/contract and complain to the OCPB on hotline 1166 or complaint.ocpb.go.th — see what a fair rental rate per unit is on the rental electricity page.
Dorm Electricity Law 2026: What Is the Maximum Per Unit?
Under the OCPB (สคบ.) notification B.E. 2568 (in force 4 Sept 2025), a dorm/rental landlord may bill tenants at most 4.88 THB/unit and may not add profit above the utility rate (the actual residential rate this period is around 3.95–4 THB/unit). Any lease clause charging more has no legal effect — if overcharged, complain to the OCPB hotline 1166. The key points on electricity are:
No charging above the utility rate
A landlord may collect electricity from tenants at a rate “not exceeding what the electricity authority (MEA/PEA) actually charges a residential user” and, under the B.E. 2568 notification, “no more than 4.88 THB/unit” — they cannot set their own electricity price to make a profit (e.g. charging 7-8 THB/unit when the utility charges around 3.95–4).
Over-charging clause = no legal effect
If a lease contains text conflicting with the OCPB announcement (e.g. an inflated electricity rate, or a deposit beyond the allowed limit), that text “has no legal effect” even if the tenant signed it. The tenant is therefore not bound to pay the unlawful rate.
Charges must be transparent
Electricity billed should reference the actual units used (meter reading) × a clearly stated per-unit rate. Tenants have the right to see the calculation and its source figures — not a vague “flat electricity fee” that can't be verified.
Important: the “fair utility rate” is not a fixed number — it's the residential rate for that period, which changes with the Ft every 4 months. Currently the residential average is around 3.95 THB/unit (incl. the current-period Ft), while the maximum a landlord may bill a tenant under the 2025 law is 4.88 THB/unit. See the latest at how many baht per unit 2026 to compare with your bill. For the specific penalty in a violation case, ask the OCPB on 1166 directly, as it depends on the nature of the offence and the legal basis applied. Note also that this framework applies where a lessor re-bills the electricity; if your unit is a condominium with the utility's own meter inside it, the position differs — the three cases are separated at condo electricity cost per unit.
Update Jul 2026: What the "First 200 Units ≤3 THB" Measure Means for Tenants
The NEPC resolution makes utility bills charge the first 200 units at no more than 3.00 THB/unit automatically (no registration), starting with Aug-2026 usage collected in the Sep-2026 bill cycle — and extends the residential class to dorms, apartments, and rental houses. Watch the unit basis: the announced 3.00 THB is an energy rate only, and it excludes Ft, the monthly service charge and 7% VAT, which every Thai bill adds on separate lines. A Type 1.2 household using exactly 200 units therefore pays about 3.52 THB/unit all-in (down from about 4.04 THB/unit without the measure), not 3.00 THB/unit — so it cannot be compared directly with the 4.88 THB/unit OCPB cap, which already includes Ft and VAT. The right also materialises at the building's UTILITY meter (the landlord's account), not the tenant's sub-meter: the landlord's cost falls, while the ceiling on what tenants may be charged remains the OCPB rule on this page (all-in calculation-method cap 4.88 THB/unit, no profit). If overcharged, report via 1567 / 1111 / OCPB 1166 — full explainer, the 3.00-to-3.52 build-up against 4.88, and the timeline: does the first-200-units 3-THB right reach tenants?
Water Charges Follow the Same Rule as Electricity
The same OCPB notification also governs water: a landlord may charge no more than what the waterworks authority (MWA/PWA) actually bills, with no profit margin, and must show the calculation. Unlike electricity, water has no fixed baht-per-unit cap figure, because official rates are volume-tiered ladders (MWA's residential ladder starts at 8.50 THB/m³; PWA's starts at 10.20 THB/m³ under the current notification, ex-VAT) and the building owner buys water through a master meter that climbs above the starting tier. The correct benchmark is therefore the building's real waterworks bill, not any single number. Tenants have the same rights as with electricity — to see the real bill and to complain to the OCPB on 1166. See nationwide water-charge statistics from our 400-listing survey (advertised medians, Bangkok vs provinces, and charge forms) at the rental water survey on the overcharge index.
How to Tell If You're Being Over-Charged
Do these 4 steps before deciding whether to complain:
Find the per-unit rate in your contract/bill — see how many baht/unit the dorm charges. Above the 4.88 THB/unit legal ceiling is clearly over the line, and anything above the real utility rate (about 3.95 THB/unit) already warrants suspicion of an added margin.
Compare with the real utility rate — the current residential rate averages about 3.95 THB/unit (incl. the current-period Ft). See how far above that the dorm is.
Read the meter yourself — note your room's meter at the start and end of the month, compute the actual units, and check it matches the units on your bill.
Keep evidence — save your lease, past electricity bills, photos of the meter, and chat messages with the landlord as evidence if you need to complain.
To know what a fair rental rate should be with worked examples, see how many baht per unit for rental rooms/dorms/condos. And to work a rental bill out from the meter readings yourself, step by step, see how to calculate a dorm or rental electricity bill, or the full utility-side formula in the 2026 bill-calculation guide. Landlord reads the meter for you? Learn to note the figures yourself and check back with how to read your electricity meter. For how far the real market charges above the cap, see the 2026 rental electricity survey. And if the meter figures and the bill diverge far enough to suspect the sub-meter has been altered — or the landlord accuses you of stealing power — read the law and the penalties in penalties for electricity theft and meter tampering.
Worked Example: How Much You Should Actually Pay
Suppose you used 120 units this month (read it off your own room meter: end-of-month reading − start-of-month reading). This table compares “charged at the real utility rate” vs “charged at 8 baht/unit by the dorm” — use it as a guide and plug in your own real units (the current residential utility rate averages about 3.95 THB/unit incl. Ft, changing each Ft period):
| Item | At the real utility rate (3.95 THB/unit) | Dorm at 8 THB/unit |
|---|---|---|
| Units used | 120 units | 120 units |
| Rate per unit | 3.95 THB | 8 THB |
| Electricity to pay | 474 THB | 960 THB |
| Excess the dorm collects | — | ~486 THB/month |
In this example, charging 8 baht/unit nearly doubles the bill = about 486 THB/month over-collected (960 − 474 THB). Since the OCPB rule bars charging above the real utility rate, that gap is what you have grounds to question. Plug in your own real units and latest utility rate — see the current rate at how many baht per unit 2026, or compute it in detail with the 2026 bill-calculation guide. The 3.95 THB/unit figure is the current-period average that moves with the Ft, while the maximum a landlord may bill a tenant under the 2025 law is 4.88 THB/unit.

Where and How to Complain
If you've talked to the landlord and are still over-charged, you have real complaint channels:
| Channel | Contact | Use for |
|---|---|---|
| OCPB (Consumer Protection) | Hotline 1166 / complaint.ocpb.go.th | Over-charged electricity/water, unfair lease terms |
| Electricity authority (MEA/PEA) | MEA 1130 / PEA 1129 | Confirm the correct residential rate to compare |
| Dormitory registrar (local welfare office) | Provincial/district social development office | Registered dorms breaching the Dormitory Act |
OCPB complaint steps in brief: (1) gather evidence — lease, bills, meter photos; (2) call 1166 or file online at complaint.ocpb.go.th; (3) enter the landlord's details, the dorm address, and the over-charging details; (4) an officer contacts you to mediate/act. Meanwhile keep collecting evidence and, where possible, pay only the correct portion first. Complaining is free, and you need not reveal your identity to the landlord if you prefer. For the detailed version — the evidence to prepare, which channel matches which problem, and the mistakes that stop a complaint going anywhere — see how to report over-charged rental electricity.
