Maybe stick to domestic then? Competence and experience go hand in hand IMHO.

It is perfectly acceptable to install 230V ventilation equipment in zone one providing it is IPX4 and meets all other requirements of BS7671. Pre 17th ed that would mean no 30mA RCD protection would have been required. (I'm assuming the install is pre 17th ed.)
