Your first electricity bill in Phuket is going to be a surprise. Not necessarily a bad one — but probably different from what you expected. The Provincial Electricity Authority (PEA) charges a tiered rate that's actually quite affordable for modest usage. The problem is that a significant portion of Phuket expats never see PEA rates at all — they pay their landlord, who adds a generous markup on top.
I've been paying electricity bills in Phuket since 2019. I've had direct PEA meters, I've had landlord-managed bills at ฿8/unit, and I've helped plenty of friends understand why their ฿15,000 electricity bill seemed to have little relationship with actual consumption. This guide covers everything: PEA's tiered structure, the legal situation on surcharges, how to read your bill, and practical ways to cut your monthly AC spend.
Phuket's most common hidden cost: landlords routinely charge ฿7–9/kWh instead of the PEA rate (฿2.35–3.24/kWh). On a 500-unit monthly usage, that's a difference of ฿2,380–3,280 per month — or ฿28,560–39,360 extra per year. Always ask your landlord what rate they charge before signing your lease.
PEA Electricity Rates in Phuket 2026
Phuket is served by the Provincial Electricity Authority (PEA), which uses a progressive tariff. The more you use, the more you pay per unit. The rates below are for standard residential accounts (type 1.2 — single-phase).
| Usage Band | Rate per kWh | Monthly units (example) | Cost for band only |
|---|---|---|---|
| Service charge (fixed) | ฿38.22/month | — | ฿38.22 |
| 0–150 units | ฿2.3488 | 150 kWh | ฿352.32 |
| 151–400 units | ฿2.9882 | 250 kWh | ฿747.05 |
| 401+ units | ฿3.2405 | any above 400 | ฿3.24/unit |
| Ft surcharge (Q2 2026) | ฿0.0354/kWh | — | Variable |
| VAT | 7% | — | On total |
The Ft (Fuel Adjustment Factor) surcharge fluctuates quarterly based on fuel costs — it's usually a few satang per unit. Check the PEA website or your current bill for the latest figure.
Real Monthly Bills at PEA Direct Rates
| Household Type | Monthly Usage | Est. PEA Bill | Notes |
|---|---|---|---|
| Studio, minimal AC use | 100–200 kWh | ฿280–630 | Fan only + fridge + lights |
| 1-bed condo, moderate AC | 200–400 kWh | ฿630–1,350 | AC 4–6 hrs/day |
| 2-bed condo, regular AC | 400–700 kWh | ฿1,350–2,470 | AC 8+ hrs/day, 2 units |
| 3-bed house/villa, heavy AC | 700–1,500 kWh | ฿2,300–5,000+ | Multiple AC units, pool pump |
| Home office + AC all day | 500–900 kWh | ฿1,650–3,050 | AC 10–12 hrs/day |
Insider tip: If you have a pool, the pump is often the second-biggest consumer after air conditioning. A typical pool pump (0.75HP) running 8 hours/day uses about 120–150 kWh/month — adding ฿400–500 to your PEA bill. Ask whether pool electricity is included in your rent or metered separately.
The Landlord Electricity Markup: What's Legal, What's Common
This is the part no landlord wants you to read. In Thailand, a 2011 Energy Regulatory Commission (ERC) regulation technically prohibits landlords from charging more than the actual PEA rate for electricity. In practice, almost no landlord in Phuket follows this. The ERC rule is widely ignored, and enforcement is essentially zero.
What actually happens in Phuket:
| Billing Arrangement | What You Pay | Extra Cost vs PEA (500 units) |
|---|---|---|
| Direct PEA meter (your name) | PEA rate ฿2.35–3.24/unit + 7% VAT | — |
| Landlord billing at PEA rate | PEA rate ฿2.35–3.24/unit | ฿0 |
| Common landlord rate ฿6/unit | ฿6/unit flat | ~฿1,380/month extra |
| Common landlord rate ฿8/unit | ฿8/unit flat | ~฿2,380/month extra |
| Very high rate ฿10/unit | ฿10/unit flat | ~฿3,380/month extra |
How to Protect Yourself Before Signing
- Ask the exact electricity rate before signing. "What do you charge per unit for electricity?" If they can't answer clearly, that's a red flag.
- Request a direct PEA meter. Some landlords will agree — especially for longer leases or larger properties. A direct PEA account means you pay PEA directly and the landlord has no involvement.
- Get it in writing. If the rate is ฿6/unit, write "฿6.00 per kWh" in the lease. Vague terms like "at cost" or "monthly meter reading" are meaningless without a number.
- Check the meter type. If there's a shared meter for multiple units, ask how readings are allocated — some landlords divide total usage by number of units rather than reading individual sub-meters, which punishes lower consumers.
How to Read a Thai Electricity Bill
If you have a direct PEA account, you'll receive a paper bill (ใบแจ้งค่าไฟฟ้า) monthly. Here are the key fields:
| Thai Field | English | What to Check |
|---|---|---|
| ผู้ใช้ไฟ / ชื่อ | Account holder name | Should match your name |
| เลขที่มิเตอร์ | Meter number | Matches your physical meter |
| เลขหน่วยก่อน / หลัง | Previous / current reading | Calculate difference for units used |
| หน่วยที่ใช้ | Units consumed (kWh) | Your total monthly consumption |
| ค่าไฟฟ้า | Electricity charge | Pre-tax energy cost |
| ค่าบริการ | Service charge | Fixed ฿38.22/month |
| Ft | Fuel adjustment surcharge | Quarterly variable |
| ภาษีมูลค่าเพิ่ม (VAT) | VAT 7% | On total before VAT |
| ยอดที่ต้องชำระ | Total amount due | This is what you pay |
| วันที่ครบกำหนด | Due date | Pay within 7 days of issue |
Where to Pay Your PEA Bill
- 7-Eleven: Scan the QR code or barcode — most convenient, no fee
- PEA office, Phang Nga Road, Phuket Town: Weekdays 8:00–17:00, cash or card
- K-PLUS app (KBank): Bill payment → Electricity → PEA → enter meter number
- SCB EASY / KTB NEXT / other banking apps: Search "PEA" in bill payment
- Direct debit: Set up at PEA office — auto-deducted from your Thai bank account
- PromptPay: Use the 15-digit reference number on the bill
Late payments: PEA charges a 1.5% monthly surcharge on overdue amounts and will disconnect power after about 30 days of non-payment. If you travel frequently, set up direct debit or ask a neighbour to keep an eye on your bills.

Air Conditioning: The Biggest Electricity Cost in Phuket
Air conditioning accounts for 60–80% of most expat electricity bills in Phuket. Understanding how your AC unit works is the single best investment you can make in reducing your monthly bill.
Inverter vs Non-Inverter: The ฿12,000 Annual Difference
Non-inverter AC units (still common in older Phuket rentals) run at full power until the room reaches the set temperature, then switch off — then on again, then off. This constant cycling is inefficient. Inverter units modulate their speed to maintain temperature continuously, using 30–40% less electricity.
| AC Type | Monthly Usage (8 hrs/day) | Monthly Cost (PEA rate) | Monthly Cost (฿8/unit) |
|---|---|---|---|
| Non-inverter 9,000 BTU | ~240 kWh | ฿730 | ฿1,920 |
| Inverter 9,000 BTU | ~150 kWh | ฿430 | ฿1,200 |
| Non-inverter 12,000 BTU | ~320 kWh | ฿990 | ฿2,560 |
| Inverter 12,000 BTU | ~200 kWh | ฿590 | ฿1,600 |
| Non-inverter 18,000 BTU | ~480 kWh | ฿1,580 | ฿3,840 |
| Inverter 18,000 BTU | ~300 kWh | ฿920 | ฿2,400 |
8 Practical Ways to Reduce Your AC Bill
- Set 26°C, not 22°C. Each degree lower increases consumption by ~8%. 26°C with a ceiling fan feels the same as 22°C without one.
- Clean the filters monthly. Dirty filters block airflow and force the unit to work harder. Takes 10 minutes and can save 10–15% on consumption.
- Use the timer function. Set AC to turn off 30–45 minutes before you wake or return — the room stays cool and you're not cooling empty space.
- Close curtains during the day. Direct sun through glass can raise room temperature by 4–6°C, forcing your AC to compensate. Blackout curtains on west-facing windows are especially effective.
- Seal gaps around doors and windows. In older Phuket construction, gaps around window frames are common. A roll of foam weatherstripping costs ฿50–100 and makes a noticeable difference.
- Run ceiling fans with AC. A ceiling fan allows you to raise the AC setting by 2–3°C while feeling equally cool, reducing consumption by 15–25%.
- Sleep mode at night. Most modern AC units have a sleep mode that gradually raises the temperature by 1–2°C during the night when your body temperature naturally drops.
- Annual service. Have your AC unit serviced (cleaned, refrigerant checked) once per year. Cost ฿400–800 per unit in Phuket. Poorly maintained units use 20–30% more power.
Setting Up a New PEA Account in Phuket
If you're moving into a property that doesn't yet have electricity or if you're taking over a direct PEA account from a previous tenant:
- Visit the PEA office at Phang Nga Road, Phuket Town (weekdays 8:00–17:00). Bring: passport, rental contract (or property ownership document), and completed PEA application form (available at the office or on PEA's website)
- Pay the refundable deposit: ฿500 for single-phase (most houses/condos), ฿1,000 for three-phase
- A PEA technician will visit to connect and meter the property (usually within 1–3 working days)
- Your account number will be used for all future bill payments
Insider tip: PEA accounts in Thailand are typically in the name of the property owner, not the tenant. This means many landlords will transfer the account to their own name between tenants. If you want a direct PEA account in your own name, you'll need the landlord's cooperation and a power of attorney in some cases — it's easier to negotiate during the lease signing than after.
