A chimney sweep invoice for an Austrian apartment building may contain several groups of services. The review should first establish which work belongs to the safety-related chimney-sweeping trade, which tariff item was used and whether an additional service was actually instructed.
Section 125 of the Austrian Trade, Commerce and Industry Regulation Act, GewO, provides for provincial maximum tariffs for this trade. The provincial governor may set tariffs for the whole province, individual sweeping districts or individual municipalities. A single maximum amount for all of Austria would therefore be unreliable.
The relevant records are the flue or heating installation concerned, the sweeping district, the service date, the individual tariff item and the description of every extra service. Whether an amount may be passed on as a residential service charge is a separate question.
