The whole part of sighning it off means you check they havnt made any mistakes. so if a customer of yours had the gas disconnected and you had to go in after and re commission the appliances - you wouldnt do it?
That's a very different scenario, and you make it clear on the quote & invoice that you're recommissioning existing appliances with a visual check. Commissioning a new appliance means taking responsibility for the quality of the installation, IMO, and that can't be a visual.
