Utility costs for a Prague flat: electricity, gas, heating and water

The advertised rent of a Prague flat is rarely the number that leaves your account each month. Between the rent and the real cost sit electricity, a heating bill that depends on whether the building has its own boiler or buys heat from a district network, water, and a set of building charges with names that do not translate neatly. A newcomer who budgets for the rent alone discovers the rest in the first winter.

Tariffs change often and by supplier, so this article does not give a price per kilowatt-hour. It explains the structure of a Czech household utility bill, who sends which invoice, and how to estimate the monthly total without relying on a guess. For the full monthly budget, see the cost of living in Prague.

Two ways utilities reach you

In Czech flats, utility costs come through one of two channels, and a lease should say which applies.

Directly from the supplier. You hold the contract and pay the supplier. This is common for electricity and, where the flat has its own gas boiler, for gas. You choose the supplier and the tariff.

Through the building or the landlord. Heat, hot water, cold water, lifts, stairwell cleaning and lighting of common areas are usually billed to the flat as part of the monthly service charges. The owner or the owners' association (the SVJ) pays the supplier and divides the cost among the flats. A tenant pays an advance to the landlord, and the landlord settles the account once a year.

Many leases combine the two: rent plus a monthly advance for services, with electricity billed separately. Our guide to how to rent a flat in Czechia as a foreigner explains how the pieces fit in a contract.

Electricity

Electricity is sold by competing suppliers over a network owned by regional distributors. Your bill has two parts: the price of the electricity itself, which the supplier sets, and the regulated charges for distribution and other fixed elements, which the Energy Regulatory Office (ERÚ) oversees. You can change supplier, and the ERÚ publishes comparison and consumer information (as of 2026; check the ERÚ).

When you move in, three steps matter:

1. Read the meter on the day of handover and photograph it with the date. The handover protocol should record the reading.
2. Register the change. Either take over the previous tenant's contract or sign a new one; the old account has to be closed at the same time.
3. Check the advance. The supplier sets a monthly advance from past consumption. If the previous tenant used little, your advance may be too low, and you will pay the difference at the settlement.

Gas, district heat and the heating question

Heating is the big variable, and it follows the building. A flat in a panel block or a modern development may receive district heat; a flat in an older building may have a gas boiler of its own, or a shared boiler house. The rules and costs differ, and our articles on district heating and heating systems explain each type.

In a building with district heat, hot water and radiators are usually included in the service charge. The cost is divided among the flats using meters or heat cost allocators on the radiators, plus a basic component related to the flat's area. A flat with a high consumption therefore pays more than its neighbours, and a flat on the top or corner of the building often uses more heat than one in the middle.

In a flat with its own gas boiler, you buy gas from a supplier and pay for it yourself. The boiler needs a periodic safety check, which the lease should assign to the owner or the tenant.

Water

Cold water and sewerage (vodné a stočné) are charged by the water company to the building, and passed on to flats by metered consumption. Many Czech buildings have a water meter in each flat, and readings are taken once or twice a year. Where no meters exist, the cost is split by an agreed key, such as the number of residents. A mid-year change in the number of people living in the flat should be reported to the landlord, since it can change the bill.

Hot water is heated either in the building (billed with heat) or in the flat (by a boiler or electric water heater, billed as electricity or gas). Always ask where the hot water is made, because it explains much of the difference between two similar flats.

Advances, settlement and the annual surprise

Most utilities are billed in advance, in equal monthly instalments, and settled once a year against the actual meter readings. If you paid too little, you pay the difference; if you paid too much, you get a refund. The law on services connected with the use of flats sets the rules for how a landlord settles service charges and the time allowed for the annual statement (as of 2026; check the Ministry for Regional Development).

A hypothetical example shows how it works. Suppose a landlord collects advances of CZK 3,000 a month for services. Over 12 months the tenant pays CZK 36,000. After the year ends the settlement shows actual costs of CZK 38,400. The tenant owes the difference of CZK 2,400. If the actual costs had been CZK 34,000, the landlord would refund CZK 2,000. These figures are invented to show the mechanism and are not typical costs.

What moves the total

The building's energy performance. Better-insulated buildings need less heat. The energy class on the certificate and the building's insulation tell you what to expect; our explainers on energy performance certificates and energy classes A to G show how to read them, and energy standards in new flats explains why new buildings usually cost less to heat.

Position and size. A top-floor flat with large windows facing north will cost more to heat than a small flat on a middle floor.

Habits. Radiator valves, ventilation and use of hot water change the bill more than most people expect, especially in buildings where costs are allocated by consumption.

The tariff. In your own electricity or gas contract, the tariff and fixed charges matter. A fixed-price contract protects against rises and also against falls, and it usually has an end date and conditions for leaving early.

The service charges. The owners' association decides some building costs through decisions in the owners' meeting. See service charges and building funds for what the charges cover and what they do not.

Owner or tenant: where the costs differ

An owner pays the same utilities and also contributes to the building's repair fund and pays property tax, which a tenant does not. The rent-versus-buy comparison therefore depends on running costs as well as the price and the mortgage. The buy-or-rent calculator on Hypoteky.com lets you include running costs when you compare owning with renting, using your own assumptions.

Frequently asked questions

Do I pay for utilities on top of the rent?

Often yes. Many Czech leases state a rent plus a monthly advance for services, and electricity is billed separately. Check the lease for what is included.

Can I choose my own electricity supplier?

Yes. Household electricity and gas are sold by competing suppliers, and the ERÚ publishes information for consumers (as of 2026; check the ERÚ). In buildings with district heat you do not choose the heat supplier.

What happens if the settlement shows I owe money?

You pay the difference by the date in the statement. If you think it is wrong, ask for the meter readings and the calculation; disputes can go to the landlord first and, if needed, to a consumer body.

Who is responsible for the heating system's maintenance?

It depends on the system and the lease. Maintenance of a flat's own boiler is usually the owner's responsibility unless the lease says otherwise.
