Do I Need a Permit to Install Electric Radiant Floor Heating? in Polen
Electric radiant floor heating sometimes requires a permit, depending on the scope and jurisdiction. Mat-based systems installed under tile during a renovation often fall under the existing electrical permit for the project. However, a standalone radiant-heat installation that adds a new dedicated circuit, requires a sub-panel connection, or covers large areas typically triggers an electrical permit. Hardwired thermostats with line-voltage connections also add a permitting trigger in many US cities.

Country-specific detail
In Poland, installing elektryczne ogrzewanie podłogowe (electric radiant floor heating) typically does not require a pozwolenie na budowę (building permit) or even a zgłoszenie (notification) when installed during an interior remont (renovation) that does not alter the building's structure or external appearance. The work must be performed by an electrician holding SEP G1 qualifications, and the completed installation requires a protokół pomiarów (measurement protocol) confirming insulation resistance and GFCI operation. If the installation increases the building's total przyłącze (service capacity) above the contracted level, a separate application to the zakład energetyczny (energy utility) is needed. New-build installations are covered under the broader pozwolenie na budowę for the project.
