The act of signing off other work on a technical basis is no different from the work we carry out on a day to day basis.
I disagree. A service, or LSC carries a certain expectation, as does a repair. Commissioning a new appliance carries higher expectations, so the onus is on whoever commissions it to carry greater responsibility. If something is wrong with the install and, say, the manufacturer's warranty is void because of it, it's your name on the benchmark, your responsibility to put it right. I'd want a lot more than a visual to take that burden on.
