Utilities, Internet, and Groceries in Phuket: Real Numbers for 2026

In a tropical climate, electricity bills can erode your budget faster than rent. A condo with three air conditioners in Phuket generates a monthly power bill of 5,000-9,000 THB. A pool villa with gardens pushes that figure to 12,000-25,000 THB. For investors calculating net rental yields, these are not minor line items - they are direct hits to your ROI.

This guide breaks down the real monthly cost of living in Phuket in 2026, from electricity tariffs to a kilogram of mango at the local market.

Quick Answer

• Electricity: 1 BR condo - 2,500-4,500 THB/month; 3 BR villa - 8,000-25,000 THB/month (varies by number of AC units and pool equipment)
• Water: 300-800 THB/month for a condo; 1,200-3,500 THB/month for a villa
• Fiber internet: 600-900 THB/month for speeds of 300-1,000 Mbps (providers: 3BB, True, AIS)
• Mobile plan: 300-600 THB/month for unlimited 5G
• Groceries for two adults: 15,000-30,000 THB/month depending on the mix of local markets versus imported goods
• CAM fee (condo common area maintenance): 40-80 THB per sqm per month

Scenarios and Options

Scenario 1: Solo resident in a studio or 1 BR condo

This is the most cost-efficient setup. With moderate AC use - running overnight and for three to four hours during the day - electricity comes to 2,500-4,000 THB. Water in most condos is either included in the CAM fee or costs a nominal 200-400 THB. Fiber internet from 3BB at 300 Mbps runs 590 THB/month. Groceries sourced primarily from local markets such as Banzaan Fresh Market or the vendors near Lotus's come to 8,000-12,000 THB.

Total utilities plus groceries: 12,000-18,000 THB/month (roughly $100-150 USD for utilities and $230-350 USD for food).

Scenario 2: Couple in a 2 BR condo

Two bedrooms mean two AC units, more laundry, and more cooking. Electricity climbs to 4,000-7,000 THB. A grocery basket for two, with regular visits to Villa Market or Makro for packaged goods, runs 15,000-22,000 THB. Add filtered drinking water in 20-litre jugs at 20-30 THB each - roughly eight jugs per month - for another 200 THB.

Total: 20,000-32,000 THB/month.

Scenario 3: Family in a pool villa

The numbers jump sharply here. Pool filtration and pump equipment add 1,500-3,000 THB to the electricity bill. An irrigated garden adds 800-2,000 THB to water costs. Factor in three or four AC units, a water heater, and a full kitchen. Professional pool maintenance - chemicals plus a pool technician - runs 3,000-5,000 THB/month. Groceries for a family with children, including imported dairy and European-brand products from Tops or Villa Market, reach 25,000-40,000 THB.

Total: 45,000-80,000 THB/month.

Electricity: why Phuket bills run higher than Bangkok

The Provincial Electricity Authority (PEA) applies a progressive tariff across Thailand: 3.2-4.2 THB/kWh plus an Ft (fuel adjustment) surcharge estimated at approximately 0.39 THB/kWh in 2026. Consumption on the island is higher than the national average simply because the climate demands it - average annual temperatures of 28-32°C mean air conditioners run year-round. Inverter-type AC units reduce energy use by 30-40% compared to conventional models. When buying a condo or villa as a rental investment, check the energy efficiency rating of installed appliances - it affects both your operating costs and tenant satisfaction scores.

Water: affordable but with seasonal caveats

Phuket draws its municipal supply from the Bang Wad and Bang Neaw Dum reservoirs. The municipal tariff is approximately 17-20 THB per cubic metre. During the dry season from January to April, pressure drops noticeably in elevated areas such as Kamala and Surin. Many villas install holding tanks of 1,000-3,000 litres as a buffer. Installation costs range from 15,000-40,000 THB as a one-time expense.

Tap water is not suitable for drinking. Bottled water in 20-litre containers costs 20-35 THB with delivery. A reverse osmosis under-sink filter system runs 8,000-15,000 THB installed, with membrane replacement approximately 2,000 THB per year.

Internet: Phuket has caught up with European standards

Fiber-optic coverage reaches over 95% of residential areas on the island. The three main providers and their current plans:

• 3BB: 300 Mbps for 590 THB/month; 1 Gbps for 790 THB/month
• True Online: 500 Mbps for 599 THB/month, including True ID streaming
• AIS Fibre: 1 Gbps for 799 THB/month

These are real-world speeds - Phuket consistently ranks among the top regions in Thailand on the Speedtest Global Index. Any plan at 300 Mbps or above handles remote work and video conferencing without issue. Installation is free with a 12-month contract.

Groceries: where to shop and what to budget

Local markets (Banzaan Fresh Market in Patong, Kaset Market in Phuket Town): rice at 35-50 THB/kg, chicken at 80-120 THB/kg, pork at 120-180 THB/kg, mango at 40-80 THB/kg, eggs at 45-55 THB for 10.

Supermarkets (Makro, Big C, Lotus's): comparable prices with a wider range of packaged goods. Local-brand milk runs 50-65 THB/litre; imported brands cost 95-130 THB/litre.

Premium retailers (Villa Market, Tops, Central Food Hall at Central Floresta): imported cheese at 250-600 THB per pack, olive oil at 300-500 THB/litre, European-style bread at 120-180 THB. Budgets can double quickly here.

The practical approach is to combine sources: fresh vegetables, fruit, and seafood from the market; dry goods and household products from Makro; occasional imported items from Villa Market. This keeps a two-person grocery budget at 15,000-20,000 THB/month with a genuinely varied diet.

Main Risks and Mistakes

• Underestimating electricity on a villa. Buyers focus on the rental income and overlook the fact that a pool and four AC units add 15,000-20,000 THB/month in operating costs. If you offer utilities-inclusive rentals, build these figures into your yield model from the start.

• Internet connectivity in new-build projects. Fiber infrastructure in recently completed developments sometimes takes 1-3 months to activate after handover. Confirm with the developer that 3BB, True, or AIS infrastructure is already in place before you commit.

• Electricity markup on rental units. Many landlords charge tenants 7-10 THB/kWh against a real PEA rate of 3.5-4.5 THB/kWh. This practice is legal but represents a near-100% markup. Owners who charge the actual rate report better long-term tenant retention.

• Water supply during peak season. Areas including Kamala, Surin, and Layan can experience reduced water pressure in March and April. A holding tank is a practical safeguard for villa owners.

• Overlooking the CAM fee. The monthly common area maintenance charge of 40-80 THB/sqm does not disappear when a unit sits vacant. On a 45 sqm apartment this amounts to 1,800-3,600 THB/month - a fixed cost that must be factored into any investment model.

FAQ

What is the electricity tariff in Phuket in 2026? The PEA progressive rate runs from 3.2 to 4.2 THB/kWh, plus an Ft surcharge of approximately 0.39 THB/kWh. A 1 BR condo averages 2,500-4,500 THB/month; a villa with a pool can reach 8,000-25,000 THB/month.

Which internet provider is best in Phuket? All three main providers - 3BB, True Online, and AIS Fibre - offer reliable fiber at 300-1,000 Mbps for 590-900 THB/month. For remote work, any plan at 300 Mbps or above performs well.

Can you drink tap water in Phuket? No. Use bottled water (20-35 THB for 20 litres with delivery) or install a reverse osmosis filter system (8,000-15,000 THB for installation).

What is the monthly grocery budget for two people? Shopping primarily at local markets and Makro: 15,000-20,000 THB/month. Adding regular premium supermarket visits for imported goods raises this to 25,000-30,000 THB.

What hidden costs should condo owners anticipate? CAM fee (40-80 THB/sqm/month), building insurance, sinking fund contributions, AC filter servicing, and water heater maintenance.

Are utilities typically included in rental prices? Rarely. The standard practice is for tenants to pay electricity and water by meter, arrange their own internet, and for the owner to cover the CAM fee.

How much more expensive is a villa compared to a condo to run? Roughly 2.5 to 4 times more in monthly utility costs. The key drivers are electricity (pool pump plus additional AC units), pool and garden maintenance, and higher water consumption.

Is 5G available in Phuket? Yes. AIS and True provide 5G coverage across the main tourist and residential areas. Unlimited 5G mobile plans run 400-600 THB/month.

Knowing these numbers before you buy - not after - is what separates a well-structured investment from one that underperforms on paper and in practice. Build utilities and maintenance into your financial model at the outset, and your yield projections will hold up in the real world.
