Do I need a chimney inspection in Czechia?
Yes — flue ways have mandatory intervals under Decree 34/2016. For solid-fuel appliances up to 50 kW (stoves, fireplaces, boilers): cleaning 3× a year for year-round operation (2× seasonal) and an inspection by a certified chimney sweep once a year, with at least 3 months between visits. Gas appliances: cleaning and inspection once a year. The good news: you may clean solid-fuel flues yourself — but the annual inspection belongs to the sweep, whose report is what your insurer asks for after a fire. A revision is a separate one-off act: new flue, fuel change, appliance swap, or after a chimney fire.
📋 The rules
- Solid fuel ≤50 kW: cleaning 3×/yr (seasonal 2×), sweep inspection 1×/yr
- Gas: 1× a year cleaning and inspection
- DIY cleaning allowed for solid fuel; inspections need a professional
- Revision: new flue, fuel/appliance change, after a chimney fire
- Keep the inspection report — insurers and firefighters ask for it
🔓 Exceptions
- Condensing gas boilers: per manufacturer/technical conditions (sometimes 1× per 2 years)
- Unused flues: no intervals, but a revision before reconnecting
⚠️ Penalties & fines
Missed intervals: fine up to CZK 10,000 (fire-protection misdemeanour). After a fire from a neglected chimney, insurers cut payouts and the fire service probes liability — damages run to hundreds of thousands.
