Do You Need a Permit to Replace a Boiler or Tankless Coil? in Polen
Usually yes. Replacing a boiler or tankless coil involves gas or oil connections, water piping, and venting changes that almost always require a mechanical or plumbing permit.

Country-specific detail
In Poland, replacing a kocioł grzewczy (heating boiler) typically requires a zgłoszenie (notification) to the Starostwo Powiatowe under the Prawo budowlane, and in many cases a full pozwolenie na budowę when the work involves changes to the instalacja gazowa (gas installation) or przewód kominowy (chimney flue). The installer must hold uprawnienia SEP (Stowarzyszenie Elektryków Polskich) kategoria G3 for gas work and provide a protokół odbioru (acceptance protocol). The Powiatowy Inspektorat Nadzoru Budowlanego (PINB) oversees compliance. If the replacement changes the moc cieplna (heating capacity) or fuel type, project documentation signed by a projektant z uprawnieniami (licensed designer) is usually required. Annual przegląd kominiarski (chimney inspection) by a mistrz kominiarski is mandatory for gas-fired boilers.
