@Murdochcat is correct, we are only testing for electrical safety, lack of smoke alarms is nothing to do with an EICR. And
@chivers67 is also correct, much of it is personal, let's face it, 230 volts AC is potentially dangerous, how can anyone say it's not?
But an EIC is not the same as an EICR, the electrical installation certificate (EIC) needs to follow BS 7671 valid today, where the electrical installation condition report (EICR) as long as we know the date when the installation was installed we can see in this example
BS 7671:2008 Requirements for Electrical Installations was issued on 1st January 2008 and is intended to come into effect on 1st July 2008. Installations designed after 30th June 2008 are to comply with BS 7671:2008.
it is the date designed which is important, not what has changed since that date.
In real terms, the whole idea of the EICR is to keep you safe, in 2004 I would not be changing a bulb with the power switched on, I would burn my hand, today with LED bulbs, I could change a bulb with it switched on, not that I would, but things have changed.
One early version of the regulations said "Lighting fittings using filament lamps installed in a room having a non-conducting floor," at that time (13th edition) there was no such thing as LED lights, so what it refers to as "filament lamps" is not what we would consider today to be filament lamps. So there is a point when even if it did comply when designed, for your safety needs changing now.
So as
@Murdochcat has pointed out, there are some items which others may not agree with, so I can see why he wants to test himself, and I can see if he follows the EICR, and then when doing the EIC, finds something does not comply, it could result in an unexpected bill, which clearly he wants to avoid.
I hate EICR's, as so often one does not agree with the other guy's findings. Where I work (volunteer) I really don't want to get involved with the electrics, as I do not agree with how things have been done. They are not wrong, just not done my way.
