I think most would agree that a system that ensured quality of work and adherence of standards is a good idea,but here's the shock,we havent got one.So what your left with,like it or not,is a vast and varied cornucopia of properties and installations that vary from poor to dangerous. We have all probably visited some. This does NOT prevent these from changing ownership and being in constant use. So how to deal with this large,on-going and increasing issue? Well,having a thorough inspection,testing and assessment by a competent person who is prepared to stand by that judgement,subject to any noted restrictions,has got to be ONE way. I believe that the phrase "signing off someone elses work..." over simplifies the problem that is already out there and you can give the process any fancy nomenclature,but it will merely be a version of an EICR. This situation,of course,should not be,if the system to date had functioned properly,but it has not. So i say let those handy and knowledgable help the job out and,god forbid,earn a few quid :troll:
