Spot on, when I joined ELECSA they said "you can't carry out EICRs unless you pay the extra ÂŁxxxx" I pointed out I can do what I damn well like without paying them for anything other than notifyable work. They didn't like it, but when I asked them what the extra fee covered there was a lot of huffing and puffing but they couldn't come up with a single thing.
When I joined ELECSA, they advised me that I don''t need the extra cert for EICRs, and probably only useful if doing a lot of them, e.g. for councils, insurance companies etc, who want to see formal assessment. If doing just the occaisional EICR, they advised me not to bother! It was refreshing not to have them try to sell me something I don't really need!
