Utilities are the budget line owners and renters in Phuket underestimate most often at the start. The spread is wide: a studio with no air conditioning barely registers an electricity bill, while a villa with a pool and constant AC can easily run five times higher. Here is a breakdown of what electricity, water, internet and condo fees really cost, where landlords build in a markup, how to read a bill in kilowatt-hours, what a tenant pays versus an owner, and how eco-certification lowers bills for owners in newer projects.

1. What makes up a utility bill
In Phuket, a monthly utility payment usually breaks down into four items:
- electricity — the largest and most variable part of the bill;
- water — fixed and almost always cheap;
- internet and mobile — fiber plus a SIM card or eSIM;
- maintenance fee — a separate line for condo and villa-complex owners, not strictly a “utility” but always part of the overall cost of ownership.
The overall range spans from a modest sum for an AC-free studio to a noticeably higher one for a villa with a pool. For the broader picture, see cost of living in Phuket and cost of living in Thailand.
2. Electricity: the government tariff
Electricity in Phuket is supplied by the Provincial Electricity Authority (PEA) — the state utility responsible for the grid in every province outside Bangkok and its surroundings. The government tariff runs about 4–5 THB per kilowatt-hour under a direct contract with the utility. This is the rate owners aim for when they put the meter in their own name after buying a unit or house.
| Property type | Electricity, govt. tariff | Main driver |
|---|---|---|
| Studio / 1BR | $50–100/mo | AC in the bedroom |
| 2BR apartment | $80–150/mo | AC in 2+ rooms |
| Villa / 3BR with pool | $150–350/mo | AC in every room + pool pump |

3. How to read the bill: kilowatt-hours × rate
An electricity bill is always the product of two numbers: consumption in kWh (the difference in meter readings over the month) and the rate per kWh. The first number depends on you — how many air conditioners run and how, the water heater, the pool pump. The second depends on who issues the bill: the PEA at the government tariff, or the landlord at the rate written into the lease. On identical consumption, the difference looks like this (300 kWh is a nominal volume used purely as a worked example):
| Rate | Who bills this way | Bill for 300 kWh | Difference vs govt. tariff |
|---|---|---|---|
| 4.5 THB/kWh | PEA, direct contract | 1,350 THB | — |
| 7 THB/kWh | Lower end of landlord markup | 2,100 THB | +56% |
| 8 THB/kWh | Typical lease rate (see the case in section 14) | 2,400 THB | +78% |
| 10 THB/kWh | Upper end of landlord markup | 3,000 THB | +122% |
The practical takeaway: a lease should state both numbers — the per-kWh rate and the meter reading on move-in day. Photograph the meter on moving in and moving out: it is the only protection against a dispute over how many kilowatt-hours you consumed. If the bill comes from the complex’s management company, ask for a breakdown — readings, rate and period; a refusal to provide one is a warning sign in itself.
4. Landlord markup: where money leaks out
When renting, the meter is often registered to the landlord rather than the tenant — and that is where a legal but noticeable markup appears. Instead of the government’s 4–5 THB/kWh, landlords frequently charge 7–10 THB/kWh — a difference that can push the total electricity bill up by 40–100%.
This is not a scam: owners are entitled to set their own rate as long as it is written into the lease. The real problem is that tenants often learn the markup only after the first bill arrives. The rule is simple: confirm the per-kWh rate before signing, not after moving in. For more on hidden rental costs, see renting in Thailand.
5. Air conditioning — the main variable
Across every scenario, air conditioning drives 60–80% of the electricity bill. A few practical takeaways:
- inverter split units run 20–30% more efficiently than older models at the same cooling capacity;
- 24–26°C instead of 20–22°C noticeably reduces compressor load;
- the number of running units matters more than floor area — a studio with two AC units can cost more than a villa with one well-insulated floor.
Seasonality matters too: during the hot months (March–May), AC bills rise island-wide regardless of location.
6. Water: tariff and quirks
Water is the most predictable utility item. The Provincial Waterworks Authority (PWA) keeps the tariff low (the PWA website has an official tariff calculator by consumption volume), and in most rental agreements the markup on water is either absent or minimal.
| Item | Range | Note |
|---|---|---|
| Water (any property type) | $5–15/mo | Tariff barely scales with floor area |
| Landlord markup on water | usually 0–10% | Far smaller than on electricity |
The one exception is villas with their own pool and garden: watering and pool top-ups add a moderate but noticeable amount compared with an apartment.
7. Internet and mobile service
Fiber internet is available almost everywhere on Phuket, including resort areas near Layan and Bang Tao beaches — relevant for owners working remotely too. A typical setup includes:
- home fiber (AIS Fibre, True, 3BB and similar) — stable rates, speed sufficient for video calls and streaming;
- mobile service / eSIM — inexpensive data packages with good coverage even outside tourist zones.
The combined line item runs $20–35/month per person for home internet and mobile together. For anyone planning to work from Thailand long-term, see Phuket for remote workers.
8. Condo maintenance fee — not a utility
It is important not to confuse utility bills with the common area maintenance fee (CAM fee). This is a separate item paid by the unit owner in a condo complex regardless of whether they live there or rent it out:
- covers cleaning, security, pool upkeep, landscaping, lobby and general infrastructure;
- calculated as a fixed rate per square meter per month — per the catalogue cards, 75 THB/sqm/month at Layan Green Park and 85 THB/sqm/month at Layan Verde;
- does not depend on how much electricity or water a specific unit consumes.
Alongside the CAM fee sits one more owner payment — the sinking fund, a one-off contribution to the building’s capital repair fund at purchase: 650 THB/sqm at Layan Green Park and 850 THB/sqm at Layan Verde. How these charges work and what they pay for is covered in sinking fund and CAM fees. These are a recurring (CAM) and a one-off (sinking fund) ownership cost that should be budgeted separately from rental income — see the methodology in how to calculate ROI in Phuket.
9. Tenant, owner, rental pool: who pays for what
The same unit costs different amounts depending on the role you occupy in it. Below is who usually carries each item (the actual split is always fixed by the contract):
| Item | Tenant (long-term lease) | Owner living in the unit | Owner with the unit in a rental pool |
|---|---|---|---|
| Electricity | Pays at the lease rate (often 7–10 THB/kWh) | Pays the PEA at the govt. tariff (4–5 THB/kWh) | Guests’ usage is a pool operating expense, deducted before profit is shared |
| Water | Pays, markup usually 0–10% | Pays the PWA at the govt. tariff | Pool operating expense |
| Internet and mobile | Pays directly or included in rent | Pays directly | Included in the hotel service, pool expense |
| CAM fee | Does not pay (built into the rent) | Pays monthly, per sqm | Owner pays monthly, per sqm |
| Sinking fund | Does not pay | Pays once at purchase | Pays once at purchase |
To get a sense of scale, here are the CAM fee and sinking fund for real unit sizes from the catalogue (calculated at the card rates: 75/650 THB for Layan Green Park, 85/850 THB for Layan Verde):
| Unit | Area | CAM fee per month | Sinking fund, one-off |
|---|---|---|---|
| Layan Green Park, phase 2 studio | 36.7 sqm | 2,752 THB | 23,855 THB |
| Layan Green Park, phase 2 one-bedroom | 43.7 sqm | 3,278 THB | 28,405 THB |
| Layan Verde, studio | 36.2 sqm | 3,077 THB | 30,770 THB |
| Layan Verde, one-bedroom | 51.9 sqm | 4,412 THB | 44,115 THB |
For an owner in a rental pool, the third column of the first table is the one that matters: guests’ electricity and water are a pool expense, not a separate bill to the owner, and only after all operating expenses is net profit split 60% to the owner and 40% to the management company. That is precisely why the building’s energy efficiency (section 10) affects an owner’s income directly: the lower the electricity cost, the more net profit is left to distribute. How the management programme works is covered in rental management programme in Phuket.
10. Eco-certification: how to cut bills
Some newer Phuket projects are built to energy-efficiency standards, which directly lowers bills for owners and tenants. Layan Green Park, Phuket’s first eco condo-hotel, holds an international EDGE certificate: energy-efficient building systems deliver savings of up to 40% on utility bills compared with a conventional building of similar class.
What is behind the acronym. EDGE (Excellence in Design for Greater Efficiencies) is a green-building certification system developed by IFC, a member of the World Bank Group. Under the standard’s rules, a project is certified only if it demonstrates at least 20% savings across three areas at once — energy, water and the embodied carbon of materials — compared with a conventional building in the same location. So 20% is the floor for any EDGE building, while the “up to 40%” claimed for Layan Green Park is the developer’s upper estimate for this specific project. In practice, the savings come from insulating facade and roof materials, energy-efficient glazing, efficient air conditioners and lighting, and water-saving fixtures.
For an investor, this is not just a green image — it is a concrete line in the income model: a unit in the rental pool with lower operating costs on electricity and water keeps more net profit, which is split between the owner (60%) and the management company (40%) — a benchmark yield of roughly 8–10% net annually with a payback period of around 12 years. The same logic underpins Layan Verde, an eco-district of 774 residences 700 meters from Layan beach. What else sets the two projects apart is covered in Layan Verde vs Layan Green Park.
11. Seasonality: budgeting month by month
An electricity bill in Phuket is never the same all year round — it follows the climate. Budget for the peak month, not the average:
| Period | Climate | What happens to the bill | How to plan |
|---|---|---|---|
| March–May (hot season) | Highest temperatures, little rain | Peak AC usage: +30–50% versus the cooler months | Put the year’s maximum here |
| June–October (rainy season) | Humid, cloudy, lower temperatures | AC runs less, but dehumidifying is often added; in villas, pool cleaning after downpours | Mid level; watch humidity, not just temperature |
| November–February (high season) | The most comfortable months | Minimal AC usage for residents; for units in a pool — maximum guest occupancy | For a pool owner, the bill rises with occupancy — that is normal |
Two consequences follow. A tenant signing a one-year lease in November should budget for the March bill in advance rather than extrapolating from the first comfortable months. An owner with a unit in a rental pool should remember that higher operating costs in high season come together with higher income, and both fall in the shoulder months; more on the seasons in rental seasons and occupancy in Phuket and Phuket’s rainy season.
12. Checklist before a lease and before a purchase
Before signing a lease:
- The per-kWh rate is written into the lease as a number, not as “at the owner’s tariff.”
- Electricity and water meter readings on move-in day are recorded in the handover note and photographed.
- It is clear whose name the meter is in — the PEA directly, the landlord, or the complex’s management company.
- It is confirmed whether internet is included in the rent and whose name the provider contract is in (on moving out it has to be closed or transferred).
- The utility deposit amount and the refund procedure are checked.
- You have calculated the peak month (March–May) at your AC usage pattern, not the average.
Before buying a unit:
- The CAM fee per sqm and the rules for its indexation are stated in the sale and purchase agreement — not only in the marketing brochure.
- The sinking fund is stated as a separate per-sqm amount and included in the deal budget alongside the other closing costs — the full list is in costs of buying property in Phuket.
- It is clear which tariff owners pay for electricity and water — the government rate, or through the management company with a markup (the Layan Green Park card states: government tariff).
- If the developer claims eco-certification, you have requested the certificate itself (EDGE or equivalent), not just a mention on the website.
- For a unit in a rental pool, you have requested the pool’s operating expense structure: exactly what is deducted before profit is distributed.
- The utility items are cross-checked against the general property handover checklist.
13. Pitfalls
- Not confirming the electricity rate before signing. The gap between 4–5 THB and 7–10 THB/kWh turns a “cheap” rental expensive from month one.
- Confusing the condo fee with utilities. The common-area charge is a separate line and does not replace electricity and water bills for your own unit.
- Ignoring AC seasonality. In the peak hot season, an electricity bill can rise 30–50% versus cooler months — budget for the peak month, not the average one.
- Not checking the meter type. If the meter is registered to the landlord rather than directly to the PEA, you cannot verify the government tariff yourself — you can only negotiate the rate in the contract.
- Ignoring energy efficiency when choosing a unit. The gap between an ordinary building and an EDGE-certified one is tens of dollars a month for years to come.
- Not recording the meter reading on move-in. Without a photo and a handover note, a dispute over “extra” kilowatt-hours on move-out is not resolved in the tenant’s favour — there is no way to prove the starting reading.
- Leaving the sinking fund out of the purchase budget. A one-off 650–850 THB/sqm for a studio is tens of thousands of baht on top of the unit price; if it is missing from the calculation, the deal budget is understated.
- Comparing utilities with another city from memory. A budget that balanced in a Bangkok apartment does not carry over to a villa with a pool by the sea — a different set of electricity consumers, a different rate.
14. Case study and takeaway
A family that relocated to Phuket and rented a villa with a pool in Bang Tao budgeted $150/month for utilities, based on the apartment they had rented in Bangkok. The actual bill for the first hot month (March) came to $340: a landlord markup (8 THB/kWh instead of the government’s 4.5) and continuous AC running in four rooms plus the pool pump were the drivers. After recalculating, the family switched to a 25°C setting instead of 21°C and added inverter units in two rooms — the bill dropped to $220/month from the second month on.
Let us look at what worked. Of the two factors in the bill, the family could influence only one — consumption in kilowatt-hours: the 8 THB rate was fixed by the lease until the end of the term. That is why they approached the next lease differently — starting with the question of the per-kWh rate rather than the monthly rent: at their level of consumption, the difference between 8 and 4.5 THB per kWh was worth more than haggling a few thousand baht off the rent.
The takeaway is simple: utility costs in Phuket are manageable once you know the structure of the bill in advance. Electricity is the main variable and the main source of markups, water and connectivity are predictable, and the condo fee and sinking fund are separate, mandatory lines for owners. Projects with eco-certification like Layan Green Park remove part of this burden structurally, not through the tenant’s own thrift.
