Temporary Electricity and Water for Construction in Thailand

Why You Need Temporary Electricity and Water Before Work Starts

Arranging temporary electricity and water for construction is a step many homeowners never think about until the crew arrives on site and there is no socket for the rebar cutter and no water to mix mortar. Most vacant plots in the Thai provinces have no meter of their own, simply because no house, and therefore no house number, has ever existed there.

Power and water are the two things a building site cannot do without from day one. Pile driving, tying rebar, cutting formwork and welding all run on electricity, while concrete pouring and curing, bricklaying and plastering consume large volumes of water every day. If either one is not ready, the whole project schedule slips.

Many people plan to run a line from a neighbour’s house in the meantime. That works as a short-term fix and depends entirely on the neighbour’s goodwill, but in Korat or Roi Et, where plots can sit a hundred metres apart, a cable that long suffers voltage drop and the shared electricity bill becomes hard to settle. Applying for your own temporary meter is the cleaner route.

Applying for Temporary Construction Power with the PEA: What to Prepare

Everywhere outside Bangkok and its neighbouring provinces, the electricity supplier is the Provincial Electricity Authority (PEA). You apply at the PEA branch responsible for the area where the land sits, not the branch nearest your current home. Whichever district the plot is in, that district’s branch handles the request.

The core documents are a copy of the landowner’s ID card, a copy of the chanote (title deed) or other land document, the building permit (the Or. 1 form issued by the local Subdistrict Administrative Organization, known as the SAO or Or Bor Tor, or by the municipality), and a copy of the house registration book if one exists. Where the land has no house number yet, officials use the building permit to confirm the location. If your contractor files on your behalf, you also need a power of attorney with ID copies from both parties.

The item most often forgotten is a wiring diagram for the temporary supply and the site distribution board, which must be installed and signed off by a licensed electrician. PEA inspects the board, breakers and earthing before fitting the meter. If the installation does not meet the standard, they will ask for corrections and schedule a new inspection, which adds several more days.

The Temporary Power Process, and How Many Days It Takes

The process starts with an application at the branch, or through PEA’s online channel, which is now available in many areas. An officer then visits the site to check where the nearest power pole is and whether extra poles or a line extension are needed, after which you receive a quote to pay.

Once payment is made, PEA technicians install the meter and connect it to the temporary board you have prepared. If the plot fronts a road with existing poles, the whole process usually wraps up in roughly one to two weeks, though the actual timeline varies by branch and how busy they are at the time.

The difficult case is land several hundred metres from the last pole, which is common with orchard plots around Pak Chong or rice-field land around Roi Et. PEA has to set additional poles and string new line, the landowner pays for that extension, and the wait can stretch to a month or more. Check the distance from the nearest pole to the plot before you buy, or at the very latest before you sign a construction contract.

Construction Power Costs More Than a Household Tariff, So Who Pays?

A temporary construction meter is billed at a higher rate than a normal residential connection, because PEA classifies it as temporary use and it does not qualify for the household tariff. Anyone shocked by the first month’s bill is usually seeing this, not a crew being wasteful with power.

At installation there is an application fee, a usage deposit and equipment charges, and each branch quotes the real figures after the site survey. Ask clearly which items are refunded when the temporary meter is cancelled and which are not, and keep every receipt.

Your construction contract should state plainly who carries the electricity and water costs during the build. Some builders include them in the lump-sum price, others have the owner pay on actual usage. Both approaches work, but if the contract is silent it tends to become an argument the day the bill arrives.

When the house is finished and has received its house number, you must apply again for a permanent meter. A temporary meter does not convert automatically. Owners often forget this and keep paying the temporary rate for months after moving in.

Temporary Water for Construction: Where to Apply, and What If No Main Runs Past

Provincial water comes from two systems. If the plot is inside an area served by the Provincial Waterworks Authority (PWA), such as Korat city or the larger district towns, you apply at that PWA branch office. The documents mirror the electricity application: ID card, land document and building permit, after which staff survey the pipe route.

A great many plots outside the towns, however, are served by village water systems run by the SAO or municipality, and you apply directly at that local office. This route is usually cheaper and faster, but pressure and consistency may not be enough for construction when the whole village draws water at the same time, so always keep a holding tank on site.

Another group of plots has no water main at all. The options are to drill a borehole or dig a shallow well, which many owners do anyway because they will keep using it after moving in, or to buy water delivered by truck. Per-load water looks cheap, but multiplied across every concrete-pouring and plastering day of the project the total is usually far higher than expected.

Whatever the source, test the water before work begins to confirm it is clean enough for mixing concrete. Water with high salt, rust or sediment content weakens concrete and shortens the life of reinforcing steel, a problem that stays hidden until the house is several years old.

Planning Power and Water So They Are Ready on Day One

The right moment to apply for temporary electricity and water is the day you receive the building permit, not after the contractor’s contract is signed. The permit is the last document both PEA and the water authority need, and every other step can run in parallel.

While you wait, have the contractor prepare the temporary distribution board, its mounting post, the earthing and the water holding tank on site, ready for inspection. If everything is in place on the day the officer surveys, the installation can often be done in a single visit without a return trip.

The OBILIS team builds the temporary electricity and water applications into the project plan from the document-preparation stage, and states in the contract which of these costs sit inside the lump-sum price, so the real start date matches the agreed one instead of slipping while everyone waits for a meter.

To get a rough budget before you talk to anyone, try our house price calculator, or contact the OBILIS team to talk through your plot.

Finally, photograph the meter position, meter number and opening reading on installation day, then note the reading at the end of every month against the bill. This simple habit shows which phase of the work used unusually high power or water, and lets you settle utility costs with the contractor without a dispute.

Frequently Asked Questions

How many days does temporary construction electricity take in Thailand?

If the plot sits next to an existing pole and the paperwork is complete, expect roughly one to two weeks from application to meter installation. If poles must be added to extend the line, it can take a month or more. Actual times vary by branch and area.

Can I get a temporary meter without a building permit?

PEA generally asks for the building permit or equivalent proof from the local authority with the application, because it confirms that construction is genuinely taking place at that location. Finish the permit first, then apply for power.

No water main reaches my land. Should I drill a borehole or buy water by the truckload?

If you plan to live in the house long term and the area has groundwater, drilling is usually the better value because you keep using it after moving in. Trucked water suits short jobs or sites where boreholes yield poor water. Have a driller assess the water table before deciding.
