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 real residential rate in Thailand is around 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.
What the Law Says About Rental / Dorm Electricity
Thailand's Office of the Consumer Protection Board (OCPB / สคบ.) issued an announcement designating “leasing a building for residential living” (dorms, rented rooms, apartments, leased condos) as a contract-controlled business. That means the lease must be fair within a legal framework. 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” — they cannot set their own electricity price to make a profit (e.g. charging 7-8 THB/unit when the utility charges around 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 4 THB/unit.

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.
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. If it's clearly above ~4-5 THB/unit, be suspicious.
Compare with the real utility rate — the current residential rate is about 4 THB/unit (around 4.2 with Ft + VAT). 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 compute the bill from your own usage, use the 2026 bill-calculation guide.
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 is around 4 THB/unit, changing each Ft period):
| Item | At the real utility rate (~4 THB/unit) | Dorm at 8 THB/unit |
|---|---|---|
| Units used | 120 units | 120 units |
| Rate per unit | ~4 THB | 8 THB |
| Electricity to pay | ~480 THB | 960 THB |
| Excess the dorm collects | — | ~480 THB/month |
In this example, charging 8 baht/unit nearly doubles the bill = about 480 THB/month over-collected. 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 ~4 THB/unit figure is an approximate rate that moves with the Ft period — it is not a fixed statutory ceiling.
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.
