It's a ridiculous idea, where did you dream that one up?
However, it is only a matter of time before someone in the (parasite) insurance industry cottons on to the clause in every home insurance policy about keeping the property in good order through proper maintenance and uses it as a get out of paying a claim excuse.
We will then witness a scramble as all insurers make regular EICRs a stipulated condition, this will be closely followed by a race to the bottom as idiotic people undercut each other in the hope of cornering their local market in them. Following this will be a massive upsurge in drive by reporting with every property being given a clean bill of health.
RIP domestic electrical trade, it was **** poor to start with, then got worse.
