We do - and for that reason I would not participate in a forum which discussed 'voting'. However, in dramatic contrast, politics affects me every day of my life, so I might well (although I don't!) feel inclined to participate in a 'politics' forum.
What you don't seem to appreciate is that those non-electricians who, like me, are regular participants in this forum undertake electric work, (and not necessarily all 'simple' work) much more frequently than once in a blue moon.
I do not have to "t*t about with it continually". I undertake routine maintenance and repair, just as with any electrical installation (although there is probably more than that than most people experience, because of teh scale of the installation) and occasional additions/modifications.
I wasn't actually talking about "issuing an EICR" but, rather, simply enjoying the reassurance of inspecting and testing my installation more frequently than most people would do, or I could afford to have done. However, what makes you think that one meeds to be "qualified" to 'issue an EICR', should one so wish?
Only if I were incompetent, just as they would probably have a field day if it emerged that a so-called 'electrician' (with some 'qualifications') had undertaken incompetent electrical work.
However, insurance companies could be the least of your problems. When you undertake electrical work 'once in a blue moon', do you undertake all the necessary proper testing? If not, then you could well be committing a criminal offence. The law (Part P of the Building Regulations) requires that "Reasonable provision shall be made in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury.” and I imagine that a Court would probably feel that the "reasonable provision" should include the undertaking of recognised tests as required by BS7671 to confirm that the law was being satisfied.
