Utility bills in a Prague flat: what to budget and who sends the bill

You sign a lease at a rent that fits your budget, and then March brings a statement from the heating company. Nothing is wrong. The rent was never the whole cost. Utilities are the second budget of a Prague flat, and they follow the seasons.

We do not give prices, because tariffs, building types and habits make any figure unreliable. This guide shows what the costs are, who bills them and how to estimate your own.

Two kinds of bill

Our guide to who pays what in a Prague rental explains the structure. For budgeting, split utilities in two.

Paid through the landlord or building (service advances). Heating, hot and cold water, waste, the lift, cleaning of common areas and corridor lighting. You pay a monthly advance with the rent, and an annual statement (vyúčtování) settles the difference between the advance and actual cost. Rules sit in the Act on services connected with the use of flats.

Contracts in your name. Electricity and gas are normally contracts between you and a supplier. Internet, mobile and TV are yours too.

What drives each cost

Heating. It is the biggest seasonal swing. Many Prague flats are on district heating, others have a gas boiler, electric heating or a building boiler. Insulation, window quality and floor level matter. A top-floor flat in an uninsulated block costs more to heat than a middle-floor flat in an insulated one. New buildings must meet the nearly-zero-energy standard, which has applied to all new buildings since 2020 (as of 2026; check the Ministry of Industry and Trade). If you want to compare, you can browse new-build flats in Prague on Novostavby.com (in Czech) and ask developers about energy class.

Hot water. Often metered separately and priced higher than cold because it includes the cost of heating.

Electricity. Appliances, lighting, an electric hob, a dryer and any electric heating. Your own habits matter most.

Gas. Only if the flat has a gas boiler or hob.

Internet and mobile. Compare packages and contract length.

Television and radio. Czech public broadcasting has its own fees. Check the Czech Television and Czech Radio sites for what applies to your household.

How to estimate before you sign

The most useful number in the whole process costs you one question. Ask the landlord or the previous tenant what the bills were last January.

If you move in, take meter readings the same day; see taking meter readings. Read the move-in checklist too.

Choosing an energy supplier

Electricity and gas supply is a competitive market, and you can choose among suppliers. The Energy Regulatory Office (ERÚ) regulates the sector and explains consumer rights. Before signing, check:

• The price per unit and the monthly fixed fee.
• The contract length and what happens at the end.
• Exit and cancellation terms.
• Whether the advance is set realistically.

Doorstep and phone offers can be pushy. Do not sign on the spot, read the contract, and remember that distance contracts carry a 14-day withdrawal right (as of 2026; check ČOI). Disputes can go to the Czech Trade Inspection Authority (ČOI) and the ERÚ in their areas.

Roommates and shared bills

Sharing a flat? Name who holds each contract, set up a shared payment routine and keep copies. Our guide to roommates and splitting bills covers it.

Budget the winter, not the average

Plan on the winter bill, not the yearly mean, and put the difference aside in the summer. If your advances are lower than your real use, expect a statement with a payment due. If they are higher, you get a refund. Both are normal. For the wider picture, see how much money you need to live in Prague and the cost of living budget lines.

Heating, ventilation and the winter bill

Heating is the line you can influence most. In buildings with central heating, radiators often have thermostatic valves: learn how they work and turn them down when you are out. In a flat with its own boiler or electric heating, the settings matter even more. Closing doors between heated and unheated rooms helps, and so does airing the flat briefly with the windows wide open instead of leaving them tilted for hours, which wastes heat and does little for damp.

Damp and mould are winter problems in many older flats. They are partly about the building and partly about humidity, so ventilate after cooking and showering and keep furniture a few centimetres from outside walls. If mould keeps returning, tell the landlord in writing. It may be a building defect rather than your habits.

Internet contracts also deserve a note. Many run for a fixed term, so ask what happens if you move before it ends, and whether the provider can transfer the service to your next address.

Frequently asked questions

Are utilities included in Prague rent?

Partly. Heating, water, waste and some building costs are usually paid as monthly advances with the rent, while electricity and gas are often billed separately.

What is a vyúčtování?

The annual statement of service costs. It compares your advances with actual costs and shows a refund or a balance to pay.

Can I choose my electricity supplier?

Yes. Compare price, fees and contract terms. The ERÚ explains consumer rights.

How do I avoid a winter shock?

Ask for last winter's bills, check the heating type and make sure the advance is realistic.

Today: ask the landlord for the last annual statement, and read the heating line first.
