Hi, Would I need to be part of a self certification scheme if i was not to do any domestic work? Just commercial based work? General maintenance in commercial/industrial premises. Also could i carry out pat testing without scheme? PIR im assuming i would need to be under scheme? I would have indemnity and liability insurance in place. I'm looking at starting own my own alongside my current job, but dont want to be part of a scheme unless i need to or the work loads picks up. Regards Aaron
