You can find out who your responsible chimney sweep is from the administration of your district, independent city or special status city.
Since 2009, there is no longer an obligation to have all tasks on your system carried out exclusively by the responsible district chimney sweep (authorized district chimney sweep). Your district chimney sweep is still responsible for inspecting your combustion system and carrying out the fireplace inspection.
Since January 2013, you have been free to choose your own chimney sweep for the non-sovereign tasks (sweeping and checking your combustion system and measuring flue gas values). Anyone authorized to carry out chimney sweeping activities in Germany is entered in a chimney sweep register kept by the Federal Office of Economics and Export Control, which is published on the Internet. From 2013, there will only be a scale of fees for the work that must be carried out by the authorized district chimney sweep. The costs for all other activities will no longer be regulated and can be negotiated.
The local authorities of your district, independent city or special status city supervise the district chimney sweeps.
