Can I still use my old boiler in Czechia?
Not a class 1 or 2 boiler — its operation has been banned since 1 September 2024. The ban hits old coal and wood central-heating boilers (typically pre-2000 designs); class 3 and better stay legal, ideally ecodesign, while gas, electric and heat pumps run unrestricted. Your class shows on the label, in the documentation, or from the mandatory boiler inspection you must have every 3 years — the first document any check will ask for. Running a banned boiler risks a fine up to CZK 50,000. Replacement subsidies are running: boiler grants up to around 95 % for low-income households, New Green Savings for everyone else. Stoves and fireplaces are not covered.
📋 The rules
- Since 1 Sep 2024: class 1 and 2 solid-fuel boilers banned
- Legal: class 3+ and ecodesign; gas/electric/heat pumps unrestricted
- Boiler inspection every 3 years mandatory — checks ask for the report
- Banned boiler: fine up to CZK 50,000
- Subsidies: boiler grants (low-income, ~95 %), NZÚ for others
🔓 Exceptions
- Local heaters (stoves, fireplaces) — outside the ban
- A proven replacement order or subsidy application: considered at checks
- Gas and electric boilers and heat pumps: emission classes don't apply to them, operation unrestricted
⚠️ Penalties & fines
Running a class 1 or 2 boiler: a fine up to CZK 50,000, imposed by the extended-competence municipality. A missing inspection report is a separate breach with a band up to CZK 20,000, and since the inspection is due every three years, it is the first document a check will demand. Burning waste in the boiler is yet another, more harshly punished offence. Complaints come from neighbours — dark chimney smoke is visible and easy to photograph. If you can prove an ordered replacement or a filed subsidy application, the office takes that into account at the check.

❓ Frequently asked
How do I find my boiler's class?
Most reliably from the mandatory three-year inspection — the technician writes the class straight into the report, so you have it in black and white. The label can hint at it; boilers from before 2000 are almost always class 1 or 2.
Does the ban cover wood stoves?
No — it applies only to solid-fuel central-heating boilers, not to local heaters such as stoves and fireplaces. Those you may keep running without any emission class, though burning waste in them remains a separate offence.
What replacements are subsidised?
Heat pumps, biomass boilers and condensing gas boilers, where the subsidies reach highest. Low-income households can get around 95 % of the cost through the boiler grants, while everyone else draws on New Green Savings.
Who can inspect me?
The extended-competence municipality, typically after a neighbour reports dark smoke from your chimney. It first requests the inspection report, and only on reasonable suspicion does it carry out a check inside the house.
What if I can't replace it in time?
The ban applies regardless of supplier lead times, so simply heating on is not a solution. A demonstrably ordered replacement or a filed subsidy application is taken into account at a check, so keep the paperwork close at hand.
